Prof. S. F. BAIRD:

Sir: I have just been in the fish market and a crew were bringing in
their fish from one of the "traps." A noticeable and peculiar feature
of the fishery this year is the great numbers of young salmon caught,
especially at the Vineyard, although some few are caught daily at
Sconticut Neck (mouth of our river). There are apparently two different
ages of them. Mostly about 2 pounds in weight (about as long as a large
mackerel) and about one-half as many weighing from 6 to 8 pounds;
occasionally one larger. One last week weighed 33 pounds and one 18
pounds. The fishermen think they are the young of those with which some
of our rivers have been stocked, as nothing of the kind has occurred in
past years at all like this.

Prof SPENCER F. BAIRD:

SIR: I received yours. I have examined carefully since your letter, but
no salmon have been taken. The run was about the two first weeks in May
and a few the last of April. Mr. Bassett had about 30 to 35 from the
trap at Menimpsha, and 10 or 12 from Sconticut Neck, the mouth of our
river. Mr. Bartlett, at his fish market, had about one dozen; 12 from
the traps near the mouth of Slocum's River, six miles west of here, and
I have heard of two taken at mouth of Westport River.

As to the particular species, I do not get any reliable information, as
so few of our fishermen know anything about salmon, and in fact the men
from the traps on Sconticut Neck did not know what the fish were.

JOHN H. THOMSON.

FISHING ITEMS. "A ten-pound salmon and seventeen tautog, weighing over
one hundred pounds, were taken from the weirs of Magnolia, Thursday
night. This is the first salmon caught off Cape Ann for over thirty
years. On Saturday morning three more large salmon were taken and 150
large mackerel. The fishermen are highly elated at the prospect of
salmon catching." (Cape Ann Advertiser, June 6, 1879.)

Albany weighing twelve and a half pounds, sold for 40 cents per pound.
The first that have been caught for years."

STATE OF MAINE, DEPARTMENT OF FISHERIES,
Bangor, August 25, 1879. [Extracts.]

DEAR PROFESSOR: We have had a great run of salmon this year, and
consisting largely of fish planted by us in the Penobscot four or five
years ago, so far as we could judge; there were a very large number,
running from 9 to 12 pounds. The east and west branches of the Penobscot
report a great many fish in the river. On the Mattawamkeag where we
put in 250,000 and upwards, in 1875 and 1876, a great many salmon
are reported trying to get over the lower dam at Gordon's Falls,
13 feet high. These fish were put in at Bancroft, Eaton and Kingman, on
the European and North American Railroad. The dam at Kingham is 13 feet;
at Slewgundy, 14 feet; at Gordon's Falls, 13 feet and yet a salmon has
been hooked on a trout fly at Bancroft and salmon are seen in the river
at Kingman, and between the dams at Slewgundy and Gordon's Falls. The
dealers in our city have retailed this season 50 tons Penobscot salmon,
and about 3 tons Saint John salmon; it all sells as Penobscot salmon.
Saint John salmon costs here, duty and all included, about 14 cents per
pound. Our first salmon sells at $1 per pound, and so on down to 12 1/2
cents the last of the season.'

Salmon at Bucksport has sold to dealers here at 8 cents. Two tons taken
at Bucksport and Orland in 24 hours. Average price at retail here for
whole season, 25 cents.

Truly, yours,

E. M. Stillwell.

STATE OF MAINE, DEPARTMENT OF FISHERIES,
Bangor, October 4, 1879.

DEAR PROFESSOR: My delay in replying to your kind letter has been from
no want of courtesy, but a desire to send you the required "data" you
asked. Neither myself nor Mr. Atkins have been able to procure them. The
weir fishermen keep no records at all, and it is difficult to obtain
from them anything reliable; while the fishermen above tidewater are a
bad set of confirmed poachers, whose only occupation is hunting and
fishing both in and out of season. They are always jealous and loth to
let us know how good a thing they make of it, for fear of us and fear of
competition from their own class.

Four or five years since I put in some 300,000 salmon fry into the
Mattawamkeag at Bancroft, Eaton, Kingsmore, and at Mattawamkeag village.
There are three dams between Mattawamkeag and Bancroft--none less than
12 feet high. About six weeks since Mr. Nathaniel Sweat, a railroad
conductor on the European and North American Railroad, while fishing for
trout from a pier above the railroad bridge at Bancroft, hooked a large
salmon and lost his line and flies. Salmon in great numbers have been
continually jumping below the first dam, which is called "Gordon's
Falls."

My colleague, Everett Smith, of Portland, a civil engineer, while making
a survey for a fishway, counted 15 salmon jumping in 30 minutes. A Mr.
Bailey, who is foreman of the repair shop at Mattawamkeag walked up to
the falls some three weeks since entirely out of curiosity excited by
the rumors of the sight, and counted 60 salmon jumping in about an hour,
within half or three-quarters of a mile of the falls. This is on the
Mattawamkeag, which is a great tributary of the Penobscot.

On the east branch of the Penobscot there has been a great run of
salmon. An explorer on the Wassattaquoik reported the pools literally
black with salmon. A party of poachers, hearing the rumor, went in from
the town of Hodgon and killed 25. I inclose you a letter to me from Mr.
Prentiss, one of our most wealthy and prominent merchants, which speaks
for itself: I will be obliged to you if you will return this, as I shall
have occasion to use it in my report.

On the West branch of the Penobscot I hear reports of large numbers of
salmon, but the breaking of the two great dams at Chesancook and the
North Twin Dam, which holds back the great magazine of water of the
great tributary lakes which feed the Penobscot, which is used to drive
the logs cut in the winter, through the summer's drought, has let up all
the fish which hitherto were held back until the opening of the gates to
let the logs through. These fish would not, of course, be seen, as they
would silently make their way up.

I regret that I have nothing of more value to give you. Hoping that this
small contribution may at least cheer you as it has me,

I remain, truly, yours,

E. M. STILWELL, Commissioner of Fisheries for State of Maine.

United States Commissioner Fish and Fisheries.
BANGOR, October 3, 1879.

M. STILWELL, Esq.,

DEAR SIR: Prof. C. E. Hamlin of Harvard, and I made a trip to Mount
Katahdin last month for scientific examination and survey of the
mountain. I had been salmon fishing in July on the Grand Bonaventure, on
Bay of Chaleur, and I could not see why we could not catch salmon on the
east branch of the Penobscot at the Hunt place where we crossed it on
our way in to Katahdin. I thought the pool from mouth of Wassatiquoik to
the Hunt place, about a half-mile, must be an excellent salmon pool, and
my guide and the people there confirmed this opinion. They said over a
hundred salmon had been taken in that one pool this season. The nearest
settlement, and only one on the whole east branch, is about six miles
out from there, and the young men go on Sundays and fish with
drift-nets. No regular fishing for market--only a backwoods local supply
can be used. These fish were about of one size--say 8 to 11 pounds.

There were never enough fish here before to make it worth while for them
to drift for them. A few years ago no salmon were caught there at all.
Twenty-two years ago, before our fish laws were enacted, the farmer at
the Hunt place used to have a net that went entirely across the river
clear to the bottom, which he kept all the time stretched across, and he
only used to get two or three salmon a week. I was there August, 1857,
with Mr. Joseph Carr, an old salmon fisher, and we fished for ten days
and could not get a rise. The net had been taken up, because the farmer
did not get fish enough to pay for looking after it.

But the stocking the river makes it good fishing and I intend to try the
east branch next season with the fly.

Very truly,

HENRY M. PRENTISS.

October 13, 1879
East Windsor Hill, Conn.

Professor BAIRD:

DEAR SIR: It may be of interest to you to know that your salmon are not
all lost. Last Friday, 10th, I was with a party of three fishing in
Snipsic Lake, and one of our party caught a salmon that weighed 1 3/4
pounds. This is the second one taken since the pond was stocked as I was
told. The other was caught this summer and weighed 12 ounces.

Cannot something be done to save our fish in Connecticut River? There is
an establishment at Holyoke, Mass., and another at Windsor Locks, Conn.,
that are manufacturing logs into paper, and I am told that the chemicals
used for that purpose are let off into the river twice a day, and that
the fish for half a mile come up as though they had been cockled.

Both of these factories are at the foot of falls where the fish collect
and stop in great numbers and are all killed. Our shores and sand-bars
are literally lined with dead fish. Three salmon have been found among
them within two miles of my office. They were judged to weigh 12, 20 and
25 pounds. The dead fish are so numerous that eagles are here after
them. I have received nine that have been shot here in the past two
seasons.

I have written you in order that the fish commissioners might stop this
nuisance and save the fish that they have taken so much pains to
propagate.

Truly yours,

Wm Hood, East Windsor Hill, Conn., October 13, 1879

SAINT STEPHEN, March 1, 1880.

Prof. SPENCER F. BAIRD
U. S. Commissioner Fish and Fisheries:

Dear Sir: I send you remarks in relation to the Restigouche and Saint
Croix Rivers, which, though crude, I am sure are quite correct, as they
are either taken from the official statistics, or are facts of which I
am myself cognizant. You may, if of use, publish any part of them.

I very much wish we could procure some young shad for the Saint Croix;
this fish was once very abundant, and perhaps would be again if
introduced. I know you have been very successful in restocking the
Connecticut. Our old people deplore the loss of the shad--say it was a
much better food-fish than the salmon. I do a great deal of shooting,
and am much interested in ornithology, and specimens of our birds that
you might want I should be happy to lookout for; do a good deal of coast
shooting winters; have been hopefully looking for a Labrador duck for a
number of seasons--fear they have totally disappeared.

I have nice spring-water conducted to my house and think of doing a
little fish-hatching in a small way. The amount of water I can spare is
a stream of about half inch diameter; the force will be considerable, as
the water rises to top of my house, some 50 feet above where I should
set trays. I write to you to ask what hatching apparatus would be best
to get, where to buy, and probable cost. I am trying to get some
sea-trout ova to hatch in it. I presume all your California ova have
been disposed of ere this.

FRANK TODD.

SAINT STEPHEN, March 1, 1880.

Prof SPENCER F. BAIRD, U. S. Commissioner Fish and Fisheries:

SIR: In regard to the Saint Croix, would say, that it was once one of
the most prolific salmon rivers in New Brunswick, but owing to the
erection of impassable dams, fifteen or twenty years ago, this valuable
fish had almost entirely disappeared. At about this time fishways were
placed in all the dams, and gradually salmon began to increase, but the
first great stimulus was given some ten years ago by the distribution of
some hundreds of thousands of young salmon in the headwaters, by the
fishery commissioners of Maine.

The Dobsis Club also placed in the Saint Croix some 200,000 or more from
their hatchery, a portion being the California salmon. With these
exceptions our river has had no artificial aid, but for the last five
years the number of salmon has largely increased, due mainly, no doubt,
to the deposits before mentioned.

The fish ways are generally in good condition (although some
improvements will be made), and fish have easy access to headwaters,
That large numbers go up and spawn is evidenced by the large numbers of
smolt seen at the head of tidal water in the spring, many being taken by
boys with the rod. I have reason to expect that our government will
hereafter distribute annually in the Saint Croix a goodly number of
young salmon which, together with the contributions of the Maine
commissioners will soon make this fish again abundant. Alewives are very
abundant and apparently increasing every year. Shad that were once
plenty have entirely disappeared. I very much wish that the river could
be stocked with this valuable fish; possibly you could kindly assist us
in this.

Landlocked salmon (here so called) are, I think, nearly or quite as
plenty at Grand Lake Stream as they were ten years ago; this, I think,
is almost entirely due to the hatchery under the charge of Mr. Atkins;
the tannery at the head of the stream having entirely destroyed their
natural spawning beds, the deposit of hair and other refuse being in
some places inches deep. The twenty-five per cent. of all fish hatched,
which are honestly returned to our river, is, I think, each year more
than we would get by the natural process, under present circumstances,
in ten years.

FRANK TODD.

SAINT STEPHEN, N. B., DOMINION OF CANADA.

Prof. SPENCER F. BAIRD, U. S. Commissioner Fish and Fisheries:

SIR: I think it has been clearly demonstrated in this Dominion that by
artificial propagation and a fair amount of protection, all natural
salmon rivers may be kept thoroughly stocked with this fish, and rivers
that have been depleted, through any cause, brought back to their former
excellence.

I would instance the river Restigouche in support of the above
statement.

This river, which empties into the Bay of Chaleur, is now, and always
has been, the foremost salmon river in New Brunswick, both as to size
and number of fish. It has not a dam or obstruction to the free passage
of fish from its mouth to its source, yet up to 1868 and 1869 the
numbers of salmon had constantly decreased. This, no doubt, was
occasioned by excessive netting at the mouth, and spearing the fish
during the summer in the pools; natural production was not able to keep
up with this waste.

In the year 1868 the number of salmon was so small that the total catch
by anglers was only 20 salmon, and the commercial yield only 37,000
pounds. At about this date, the first salmon hatchery of the Dominion
was built upon this river and a better system of protection inaugurated;
every year since some hundreds of thousands of young salmon have been
hatched and placed in these waters, and the result has been, that in
1878 one angler alone (out of hundreds that were fishing the river)
in sixteen days killed by his own rod eighty salmon, seventy-five of
which averaged over twenty-six pounds each; while at the same time the
numbers that were being taken by the net fishermen below, for commercial
purposes, were beyond precedent, amounting in that one division alone
(not counting local and home consumption) to the enormous weight of
500,000 pounds, and the cash receipts for salmon in Restigouche County
that year amounted to more than $40,000, besides which some $5,000 was
expended by anglers; this result was almost entirely brought about by
artificial propagation. A new hatchery of size sufficient to produce
five million young fish annually will no doubt soon be erected by the
Dominion Government upon this river.

A somewhat similar record might be given of the river Saguenay. Some
years ago anglers and net fishers of this river said it was useless to
lease from the department, as the scarcity of salmon was such as not to
warrant the outlay. A hatchery was built, and this state of things is
now wonderfully changed; so much so, indeed, that in 1878 salmon, from
the great numbers which were taken at the tidal fisheries, became a drug
in the market, selling often as low as three cents per pound, and
angling in the tributaries was most excellent.

Some one hundred million young salmon have been artificially hatched and
distributed in the waters of the Dominion during the last few years, and
new government hatcheries are constantly being erected.

Yours, &c.,

FRANK TODD, Fishery Overseer, Saint Croix District.



ARTICLE II

SKETCH OF THE PENOBSCOT SALMON-BREEDING ESTABLISHMENT

by

Charles G. Atkins

Written by request of Prof. S. F. Baird, for the London Exhibition,
1883

_Bulletin of the United States Fish Commission_, Vol. 3, Page 373, 1883



The rivers of the United States tributary to the Atlantic, north of the
Hudson, were, in their natural state, the resorts of the migratory
salmon, _Salmo salar_, and most of them continued to support important
fisheries for this species down to recent times. The occupation of the
country by Europeans introduced a new set of antagonistic forces which
began even in the seventeenth and eighteenth centuries to operate
against the natural increase and maintenance of the salmon and other
migratory fishes.

In many localities the closing of smaller streams by dams, and the
pursuit of the fish with nets and other implements, had already begun
to tell on their number; but it was not until the present century that
the industrial activities of the country began to seize upon the water
power of the larger rivers and to interrupt in them by lofty dams the
ascent of salmon to their principal spawning grounds. These forces were
rapid in their operations, aided as they were by a greatly augmented
demand for food from a rapidly increasing population.

In 1865 the salmon fisheries were extinct in all but five or six of the
thirty rivers known to have been originally inhabited by them. In many
of these rivers the last salmon had been taken, and in others the
occurrence of individual specimens was extremely rare. Among the
exhausted rivers may be mentioned the Connecticut, 380 miles long; the
Merrimack,180 miles long; the Saco,120 miles long; the Androscoggin,
220 miles long; and some twenty smaller rivers. There still survived
salmon fisheries in the following rivers, namely, the Penobscot, the
Kennebec, the Denny's, the East Machias, the Saint Croix, and the
Aroostook, a tributary of the Saint John. The most productive of these
was the Penobscot, yielding 5,000 to 10,000 salmon yearly. The Kennebec
occasionally yielded 1,200 in a year, but generally much less. The
other rivers were still less productive.

The movement for the re-establishment of these fisheries originated in
action of the legislature of New Hampshire, seconded by that of the
neighboring state of Massachusetts, having in view primarily the
fisheries of the Merrimack and Connecticut Rivers. The course of the
Merrimack lies wholly within the states of New Hampshire and
Massachusetts; that of the Connecticut lies partly in the state of
Connecticut, and many of its tributaries are in the state of Vermont.
These two states were therefore early interested in the project, and
their action soon led to similar exertions on the part of Rhode Island
and Maine. Within the borders of the six states mentioned, collectively
known as "New England," are all of the rivers of the United States
known to have been frequented by the sea-going _Salmo salar_, with the
possible exception of certain rivers, tributary to the Saint Lawrence,
in the northern part of New York.

The governments of these states having appointed boards of
commissioners to whom was confided the task of restocking the exhausted
rivers, other states, one after another, adopted like measures, and in
1872 the United States Government established a commission to inquire
into the condition and needs of the fisheries in general, with
authority to take steps for the propagation of food fishes.

The New England commissioners turned their attention at once to the two
most important of their migratory fishes, the salmon and the shad. The
utter extermination of salmon from most of their rivers compelled them
to consider the best mode of introducing them from abroad.

Agents were sent to the rivers of Canada, where for several years they
were permitted to take salmon from their spawning beds, and some
hundreds of thousands of salmon eggs were thus obtained and hatched
with a measure of success. After a few seasons permits for such
operations were discontinued, and the only foreign source of supply
thereafter remaining open to the states was found in the breeding
establishments under control of the Canadian Government, and even these
were practically closed by the high price at which the eggs were
valued.

In 1870 it had become clear that to a continuation of efforts it was
essential that a new supply of salmon ova should be discovered.
Attention was now directed to the Penobscot River in the state of
Maine, which, though very unproductive compared with Canadian rivers,
might yet, perhaps, be made to yield the requisite quantity of spawn.

A preliminary examination of the river brought out the following facts:
The Penobscot is about 225 miles in length. The upper half of its
course and nearly all of its principal tributaries lie in an
uninhabited wilderness, and in this district are the breeding grounds
of the salmon. The fisheries, however, are all on the lower part of the
river and in the estuary into which it empties, Penobscot Bay. There
was no means of knowing how great a proportion of the salmon entering
this river succeeded in passing safely the traps and nets set to
intercept them, but supposing half of them to escape capture there
would still be but about 6,000 fish of both sexes scattered through the
hundreds of miles of rivers and streams forming the headwaters of the
Penobscot.

It was very doubtful whether they would be congregated about any one
spot in sufficient numbers to supply a breeding station, and it would
be impracticable to occupy any widely extended part of the river, on
account of the difficulties of communication. At the mouth of the
river, on the other hand, the supply of adult salmon could be found
with certainty, but they must be obtained from the ordinary salmon
fisheries in June and held in durance until October or November, and
the possibility of confining them without interfering seriously with
the normal action of their reproductive functions was not yet
established. The latter plan was finally adopted, and in 1871 the first
attempt at this method of breeding salmon was instituted by the
commissioners' of Maine, Massachusetts, and Connecticut. The site fixed
upon for an inclosure was at Craig's Pond Brook in the town of Orland,
and arrangements for a supply of fish were made with two fishermen of
Verona at the very mouth of the river. The salmon first brought were
confined in a newly constructed artificial pond in the brook, which was
of such remarkable purity that a small coin could be distinctly seen at
the depth of 7 feet. All of these died except a few which after a short
stay were removed to other quarters. The most prominent symptom was the
appearance of a white fungoid growth in patches upon the exterior of
the fish. In a lake (locally designated as Craig's Pond) of equal
purity, but greater depth, several of these diseased fish recovered.

Of the salmon later obtained some were placed in an inclosure of nets
in the edge of a natural pond with but 7 feet of water, of average
purity, some in a shallow inclosure in a brook, and some turned loose
in a natural lake of some 60 acres area, with muddy bottom and
peat-colored water. In each case the salmon passed the summer with few
losses, arrived at the breeding season in perfect health, and yielded
at the proper time their normal amount of healthy spawn and milt,
though the great sacrifice of breeding fish by the early experiments of
the season reduced the crop of eggs to the small number of 72,000.

The conditions of success were thus sufficiently indicated, and in 1872
the same parties, joined with the United States Commission of
Fisheries, renewed operations on a larger scale, locating their
headquarters at the village of Bucksport, confining the breeding salmon
in Spofford's Pond (Salmon Pond on the general map of Penobscot
station), and establishing their hatchery on the brook formed by its
overflow. This is the lake of 60 acres in which, as mentioned above, a
few salmon had been successfully confined the year before.

Though not at all such water as would be chosen by a salmon at large,
it nevertheless proved well adapted to the purpose of an inclosure for
the breeding fish. It was shallow, its greatest depth, at the season of
highest water, being but 10 feet; at its upper end it abuts against an
extensive swamp, and almost its entire bottom, except close to the
shore, is composed of a deposit of soft, brown, peaty mud of unknown
depth. The water is strongly colored with peaty solutions, has a muddy
flavor, and under the rays of a summer sun becomes warmed to 70°
(Fahrenheit) at the very bottom.* Yet in such a forbidding place as
this, salmon passed the summer in perfect health. There were some
losses, but every reason to believe them all to have been caused by
injuries received prior to their inclosure.

* During the month of August, 1872, the bottom temperature at 1 p.m.
was never below 70°, and on six days was found to be 71°.

During and after the hottest term of each summer (the month of August)
very few died.

The supply of salmon was obtained mainly, as in 1871, from the weirs in
the southern part of Verona. They were placed in cars, specially
fitted for the purpose; and towed to Bucksport on the flood tide. From
the river to the inclosure they were hauled on drays in wooden tanks 3
feet long, 2 feet wide and 2 feet deep, half a dozen at once. From the
weirs to the boats and from the boats to the tanks they were dipped in
great canvas bags. From all this handling but few losses ensued.

In the establishment at Bucksport village the work was carried on for
four years, from 1872 to 1876, with a fair degree of success. Then
ensued a suspension till 1879, when the reappearance of salmon in the
Merrimack, Connecticut, and some other rivers renewed the hopes of
final success, and encouraged the commissioners to reopen the station.
It had, however, been found that the old location had serious defects.

The inclosure was costly to maintain, and the recapture of the fish
involved a great deal of labor and trouble. The water supplied to the
hatchery was liable in seasons of little rain to be totally unfit,
causing a premature weakening of the shell and very serious losses in
transportation. After a careful search through the neighboring country
it was found that the most promising site for an inclosure was in Dead
Brook, near the village of Orland (though within the limits of the town
of Bucksport), and for a hatchery no location was equal to Craigs Pond
Brook, the spot where the original experiments were tried in 1871. The
only serious drawback was the separation of the two by a distance of
some 2 miles, which could not offset the positive advantage of the
hatchery site. Accordingly the necessary leases were negotiated, an
inclosure made in Dead Brook, and a stock of breeding salmon placed
therein in June, 1879. Since then the work has been continued without
interruption.

It is still found most convenient to obtain the stock of breeding
salmon, as in the early years of the enterprise, from about a dozen
weirs in the Penobscot River along the shores of the island of Verona.
The fishermen are provided with dip-nets or bags with which to capture
the fish in their weirs, with tanks or cars in which to transport them
to the collecting headquarters, whither they are brought immediately
after capturing, about low water.

The collection is in the hands of a fisherman of experience, who
receives the salmon as they are brought in, counts and examines them,
adjudges their weight, and dispatches them in cars to the inclosure at
Dead Brook. The cars are made out of the common fishing boats of the
district, called dories, by providing them with grated openings, to
allow of a free circulation of water in transit, and covering them with
netting above to prevent the fish from escaping over the sides. The car
is ballasted so that it will be mostly submerged. Ten to fifteen salmon
are placed in a single car, and from one to four cars are taken in tow
by a boat with two to four oarsmen.

From the collecting headquarters to Orland village, a distance of about
5 miles, the route is in brackish water, and the tow is favored by the
flood tide. At Orland is a dam which is surmounted by means of a lock,
and thence, two miles further to Dead Brook, the route is through the
tide less fresh water of Narramissic River. The sudden change from salt
to fresh water does not appear to trouble the fish except when the
weather is very hot and the fresh water is much the warmest. The cars
are towed directly into the inclosure, where the fish are at once
liberated.

The inclosure is formed by placing two substantial barriers of woodwork
across the stream 2,200 feet apart. The lower barrier is provided with
gates which swing open to admit boats. Within the inclosure the water
is from 3 to 8 feet deep, the current very gentle, the bottom partly
muddy, partly gravelly, supporting a dense growth of aquatic
vegetation. The brook has two clean lakes at its source, and its water
is purer than that of ordinary brooks.

The collection of salmon usually continues from the first ten days of
June until the beginning of July. During the early weeks of their
imprisonment the salmon are extremely active, swimming about and
leaping often into the air. After that they become very quiet, lying in
the deepest holes and rarely showing themselves. Early in October they
begin to renew their activity, evidently excited by the reproductive
functions. Preparations are now made for catching them by constructing
traps at the upper barrier. If the brook is in ordinary volume, these
means suffice to take nearly all, but a few linger in the deeper pools
and must be swept out with seines. About October 25 the taking of spawn
begins. After that date the fish are almost always ripe when they first
come to hand, and in three weeks the work of spawning is substantially
finished.

Although the salmon are taken from the fisherman without any attempt to
distinguish between males and females, it is always found at the
spawning season that the females are in excess, the average of four
seasons being about 34 males to 66 females. This is a favorable
circumstance, since the milt of a single male is fully equal to the
impregnation of the ova of many females.

The experiment has several times been tried of marking the salmon after
spawning and watching for their return in after years. After some
experiments, the mode finally fixed upon as best was to attach a light
platinum tag to the rear margin of the dorsal fin by means of a fine
platinum wire. The tags were rolled very thin, cut about half an inch
long and stamped with a steel die. The fish marked were dis missed in
the month of November. Every time it was tried a considerable number of
them was caught the ensuing spring, but with no essential change in
their condition, indicating that they had not meanwhile visited their
spawning grounds. In no case was a specimen caught in improved
condition during the first season succeeding the marking.

But the following year, in May and June, a few of them were taken in
prime condition--none otherwise--and it several times occurred that
female salmon were a second time committed to the inclosure and yielded
a second litter of eggs. The growth of the salmon during their absence
had been very considerable, there being always an increase in length
and a gain of twenty-five to forty per cent. in weight. The conclusion
seems unavoidable that the adult salmon do not enter the Penobscot for
spawning oftener than once in two years.

The method of impregnation employed has always been an imitation of the
Russian method introduced into America in 1871. The eggs are first
expressed into tin pans, milt is pressed upon them, and after they are
thoroughly mixed together, water is added. The result has been
excellent, the percentage of impregnated eggs rarely falling so low as
95.

After impregnation the eggs are transferred to the hatchery at Craig's
Pond Brook, where they are developed, resting upon wire-cloth trays in
wooden troughs, placed in tiers ten trays deep, to economize space, and
at the same time secure a free horizontal circulation of water.

The hatchery is fitted up in the basement of an old mill, of which
entire control has been obtained. The brook is one of exceptional
purity, and a steep descent within a few feet of the hatchery enables
us to secure at pleasure a fall of 50 feet or less. The brook formerly
received the overflow of some copious springs within a few hundred feet
of the hatchery, which so affected the temperature of the water that
the eggs were brought to the shipping point early in December, an
inconvenient date. This has been remedied by building a cement aqueduct
1,600 feet long, to a point on the brook above all the springs, which
brings in a supply of very cold water.

The shipment of eggs is made in January, February, and March, when they
are sent by express, packed in bog-moss, all over the northern States,
with entire safety, even in the coldest weather.

In the following statement is embraced a general summary of the results

ARTICLE III

PENNING OF SALMON IN ORDER TO SECURE THEIR EGGS.

By C. J. Bottemanne M.D. [From a letter to Prof. S. F. Baird.]

_Bulletin of the United States Fish Commission_, Vol. 4, Page 169, 1884.



In the Dutch "Economist" of 1874 I gave a description of the fish
breeding establishment of the State of New York, and therein I mentioned
the United States salmon-breeding establishment on the Penobscot,
principally for the penning of the salmon from June till breeding time.
As you are likely aware, the Dutch Government pays yearly $4,800 to
salmon breeders for young salmon delivered in spring, at the rate of 10
cents for yearlings, and not quite (4/5) one dollar per hundred for
those that are about rid of the umbilical sac, and ready to shift for
themselves. For the latter they receive payment only if there is money
left after delivering the yearlings.

The breeders get their eggs from Germany from Schuster in Freiburg, and
from Gloser in Basel; but complain always that the eggs are from too
young individuals, that there is always too much loss in transportation,
that the eggs are so weak that after the fish have come out there is
great mortality in the fry, &c.

In this month's "Economist" I published the results on the Penobscot,
and figured out that if breeders here set to work in the same style they
would get at least four eggs to one, at the same price, and be
independent.

We have an association here for promoting the fresh-water fisheries, of
which the principal salmon fishermen are members, and also several
gentlemen not in the business, including myself. In the December meeting
I told them all I knew about the Penobscot; and one breeder got a credit
for $200 for getting ripe salmon and keeping them in a scow till he had
what he wanted, and he has succeeded pretty well. Still this is only on
a limited scale. I want to put up larger pens and in the style of the
Penobscot. In order to do this I must know exactly what is done on the
Penobscot, and how.

What is the size of the pen, how large area, how deep? Is it above tidal
water? (This I take for granted.) What is the situation of the pond
compared with the river? What kind of failures were there, and the
probable reasons therefor? In short, I would like a complete description
of the place, with the history of it. I hope you will excuse my drawing
on you for such an amount, but as the United States is the authority in
practical fish-breeding, we are obliged to come to you.

I am sorry to say that I cannot report the catch of any _S. quinnat_,
yet three fish have been sent in for the premium we held out for the
first fifteen caught, but they proved not to be quinnat. Lately I heard
that there were so many salmon caught in the Ourthe, near Liege, Belgium
(the Ourthe is one of the feeders of the Maas), which was an astonishing
fact, as salmon are seldom taken there.

MEMORANDA RELATIVE TO INCLOSURES FOR THE CONFINEMENT OF SALMON DRAWN
FROM EXPERIENCE AT BUCKSPORT, PENOBSCOT RIVER, MAINE.

By Charles G. Atkins

[In response to request of Dr. C. J. Bottemanne.]
April 7, 1884.

_Bulletin of the United States Fish Commission_, Vol. 4, Pages 170-174,
1884.



The Penobscot salmon-breeding establishment was founded in 1872, at
Bucksport; in the State of Maine, near the mouth of the Penobscot River.
The location was primarily determined by the necessity of being near a
supply of living adult salmon, to be used for breeders.

After an exploration of the headwaters of the Penobscot, which lie
mostly in an uninhabited wilderness, the conclusion was reached that the
chances of securing a sufficient stock of breeders were much greater at
the mouth of the river, where the principal salmon fisheries are
located; but to avail ourselves of the supply here afforded we must take
the salmon at the ordinary fishing season, May, June, and July, and keep
them in confinement until the spawning season, which is here the last of
October and first of November. As the salmon naturally pass this period
of their lives in the upper parts of the rivers, it was thought
essential to confine our captives in fresh water.

Later experiments in Canada indicate that they will do as well in salt
water, but the construction and maintenance of inclosures is much easier
when they are located above the reach of the tide, to say nothing of the
proximity of suitable fresh water for the treatment of the eggs. In the
precise location of the inclosures several changes have been made, but
they have always been in fresh water, and within convenient distance (5
to 10 miles) of the place where the salmon were captured.

In our experiments and routine work we have made use of four inclosures,
which I will now describe.

No. 1. In Craig's Pond Brook, a very pure and transparent stream, an
artificial pond 40 square rods in area and 7 feet in extreme depth, was
formed by the erection of a dam. The bottom of this pond was mainly a
grassy sod newly flooded. About half the water came from springs in the
immediate vicinity, and the rest from a very pure lake half a mile
distant. The water derived from the lake was thoroughly aerated by its
passage over a steep rocky bed. The transparency of the water in the
pond was so great that a pin could be seen at the depth of six feet.

This inclosure was a complete failure. The salmon placed therein were
after a day or two attacked by a parasitic fungoid growth on the skin,
and in a few days died. Out of 59 impounded not one escaped the disease
and only those speedily removed to other waters recovered. Several,
removed in a very sickly condition to the lake supplying the brook,
recovered completely, from which it is safe to infer that the cause of
the trouble did not lie in the lake water.

Of the spring water I have some suspicions, and should not dare to
inclose salmon in it again.

No. 2. After the failure of the above experiment an inclosure was made
in the edge of an ordinary lake by stretching a stout net on stakes.
This water was brown in color, and objects 4 feet beneath the surface
were invisible. The bottom was gravelly and devoid of vegetation.

The depth was 7 and one half feet in early summer, and about 4 feet
after the drought of August and September. The area inclosed was about
25 square rods in June, and perhaps half as much at the end of summer.
This inclosure was entirely successful, very few salmon dying in it
except those that had been attacked by disease before their
introduction, and all the survivors were found to be in first-rate
condition in November. This site was not afterwards occupied, because
it was inconveniently located, and was exposed to the full force of
violent winds sweeping across the lake, and therefore unsafe.

No. 3. The inclosure in use for the confinement of the stock of
breeding fish for the four years from 1872 to 1875, inclusive, was made
by running a barrier across a narrow arm of a small lake (mentioned in
official reports as "Spofford's Pond") near Bucksport village. This
body of water, about 60 acres in area in the summer, receives the
drainage of not more than 5 square miles of territory through several
small brooks, that are reduced to dry beds by an ordinary drought.
About a quarter of the shores are marshy and the rest stony. The water
is highly colored by peaty matters in solution, and all objects are
invisible at a depth of 2 feet: The bottom is composed mostly of a fine
brown peaty mud of unknown depth. Aquatic vegetation of the genera,
_Nuphar_, _Nymphaea_, _Bragenia_, _Potamogeton_, &c., is abundant. The
water is nowhere more than 16 feet deep in the spring, and 11 feet in
midsummer. The portion inclosed is 2 feet shoaler.

The inclosure occupied sometimes 8 or 10 acres, and sometimes less. The
barrier was from 400 to 600 feet long, and was formed the first year of
brush; the second and third years of stake-nets, weighted down at the
bottom with chains; and the fourth year of wooden racks, 4 feet wide
and long enough to reach the bottom, which were pushed down side by
side. The brush was unsatisfactory. There were holes in it by which the
fish escaped. A single net would not retain its strength through a
whole season, the bottom rotting away and letting the fish out, unless
before the autumn was far advanced its position were reversed, the
stronger part that had been above water being placed now at the bottom.
This method was therefore rather expensive and not perfectly secure.
The wooden racks were costly and heavy to handle, but quite secure.

The salmon placed in this inclosure had to be carted in tanks of water
overland about a mile in addition to transportation in floating cars
from 3 to 5 miles; they were transferred suddenly from the salt water
of the river (about two-thirds as salt as common sea-water) into the
entirely fresh water of the lake. To all the supposed unfavorable
circumstances must be added the high summer temperature of the water.
During August the mean was generally above 70 degrees Fahrenheit at the
bottom and several degrees warmer at the surface. Occasionally there
was observed a midday temperature of 74 degrees F. and once 75 degrees
at the bottom. Yet this proved an excellent place for our purpose, a
satisfactory percentage of the salmon remaining in perfect health from
June to November.

No. 4. The inclosure in use since 1870 at Dead Brook, Bucksport. It is
located in a gently running stream bordered by marshy ground, with a
bottom in part of gravel but mostly of mud, crowded with aquatic
vegetation. The water, supplied by two small lakes among the hills, is
cleaner than the average of Maine rivers, but does not in that respect
approach the water of inclosure No. 1. The greatest depth is about 8
feet, but in the greater part of the inclosure it is from 3 to 5 feet.
The width of the stream is from 2 to 4 rods, and the portion inclosed
is 2,200 feet long. The barriers to retain the fish are in the form of
wooden gratings, with facilities for speedily clearing them of debris
brought down by the stream.

Better results were expected from this inclosure than from No. 3, but
have not been realized. The percentage of salmon dying in confinement
has been greater, amounting commonly to about 25 percent of those
introduced, and this notwithstanding the salmon are conveyed to the
inclosure by water carriage the entire distance (7 miles) instead of
being carted in tanks.

The cause of the trouble has not yet been discovered, but there is good
reason for thinking that it lies in some of the circumstances attending
the transfer of the fish from the place of capture, and that the
inclosure itself is perfectly suited to its purpose. This view is
supported by the fact that nearly all the losses occur within a few
weeks after the introduction of the salmon and almost wholly cease by
the end of July. If the cause of disease was located in the inclosure,
we should expect it to be more fatal after a long than a short duration
of the exposure of the fish to its action, and that with the smaller
volume and higher temperature of August it would be more active than in
June and July.

The above description will, I think, give Dr. Bottemanne a sufficiently
correct idea of the character of the inclosures we have tried. There
are, however, several other points to be touched upon to put him in
possession of the practical results of our experience.

The facilities for the recapture of the salmon when the spawning season
approaches must be considered. In the lake at Bucksport village (No. 3)
we hoped at first that their desire to reach a suitable spawning ground
would induce them all to enter the small brook that forms the outlet,
which was within the limits of the inclosure. In this matter our
expectations were but partially realized. Many of the fish refused to
leave the lake through the narrow opening that was afforded them, and
were only obtained by pound-nets, seines, and gill-nets, all of which
involved a considerable expenditure of labor and material.

The drawing of a seine in a large body of fresh water is likely to be
a serious undertaking unless the bottom has been previously cleared of
snags. In this respect the long and narrow inclosure at Dead Brook
possesses great advantages, since it can be swept with a comparatively
short seine. However, the influx and efflux of a considerable volume of
water is of great advantage in enticing the gravid fish into traps that
can readily be contrived for them by any ingenious fisherman.

The existence of a gravelly bottom in the inclosure must be considered
a positive disadvantage, inasmuch as it affords the fish a ground on
which they may lay their eggs before they can be caught; but the danger
of such an occurrence is less as the bounds of the inclosure are more
contracted and the facilities for capturing the fish are better.

As to the number of fish to a given area, I think we have never
approached the maximum. I should have no hesitation in putting 1000
salmon in the inclosure at Dead Brook, which covers an area of less
than 3 acres. Of course the renewal of the water supply, or its
aeration by winds, is of importance here.

The capture and transport of the fish in June involves methods
requiring some explanation. The salmon fisheries about the mouth of the
Penobscot River are pursued by means of a sort of trap termed a "weir."
It is constructed of fine-meshed nets hung upon stakes, arranged so as
to entrap and detain the fish without insnaring them in the meshes.
They swim about in the narrow "pound" of the weir until the retreating
tide leaves them upon a broad floor.

Just before the floor is laid bare, the salmon destined for the
breeding works are dipped out carefully with a cloth bag or a very fine
bag-net and placed in transporting cars or boats, rigged specially for
the purpose, sunk deep in the water, which fills them, passing in at
two grated openings above, and passing out at two others astern, and
covered with a net to prevent escape. In a boat 13 or 14 feet long (on
the bottom) we put 10 or 15 salmon, to be towed a distance of 7 miles.
If the water is cool, twice as many can go safely, but there must be no
delay. It is very important that this car be smooth inside, with no
projections for the salmon to chafe on, and the gratings must be so
close that they cannot get their heads in between the bars.

If conveyance overland is necessary, a wooden tank 3 feet long, 2 feet
wide, and 2 feet deep, with a sliding cover, will take six salmon at a
time for a mile and perhaps farther, and they may be jolted along over
a rough road in comparative safety.

It has been our uniform experience that all the salmon that survive
till autumn were in normal condition as to their reproductive function,
and yielded healthy spawn and milt. On two occasions we suffered
serious losses of eggs. In neither instance could the loss be
attributed to any defect in the inclosure, but on one occasion the
conclusion was reached that the water which was well suited to the
maintenance of the fish was injurious to the eggs, rendering the shell
so soft that they could not be transported safely.

With the exception of the disasters enumerated above, there has been
but one that I can recall, and that was caused by the bursting of our
barriers at Dead Brook under the pressure of a flood.

METHODS EMPLOYED AT CRAIG BROOK STATION IN REARING YOUNG SALMONID
FISHES

By Charles G. Atkins, Superintendent U. S. Fish Commission Station at
Craig Brook, Maine.

_Bulletin of the United States Fish Commission_, Vol. 13,
Pages 221-228, 1893.



The station of the U. S. Fish Commission at Craig Brook was founded in
1889, on the same site where, in 1871, the first attempt at the
artificial spawning of salmon in the United States was made. This site
had been selected by the commissioners of fisheries of the States of
Maine, Massachusetts, and Connecticut for that experiment because of
its proximity to the salmon fisheries of the Penobscot River and the
facilities presented for the maturing of the spawn that might be
obtained.

The collection of spawn has been carried on in the vicinity annually
from 1871 to the present time, with the exception of the three years
1876,1877, and 1878, and since 1879 the development of the spawn has
been conducted constantly at Craig Brook. No attempt was, however, made
to rear the fry of any species until 1886. Two years later it was
definitely determined to found a permanent station at Craig Brook, and
in 1889 the purchase of the grounds was effected and permanent
improvements begun.

The station is located in the town of Orland, Me., 7 miles east of
Bucksport, a seaport on the Penobscot River. Its territory embraces a
tract of land extending between Allamoosook Lake and Craig Pond and
embracing within its limits the entire length of Craig Brook, which
connects those two bodies of water. Its latitude is about 44 degrees
42' N. The mean annual temperature and precipitation are believed to
approximate those of Orono, 25 miles distant, namely, 42.48° F. [5.8°
C.] and 45.44 inches [116 cm.]. The range of air temperature observed
at the station is from 18° F. below zero to 92.5°F. above [-27.7° C.
to 33.6° C.]. Frosts not infrequently occur as late as the 1st of June
and as early in autumn as the first week in September. The lakes in the
vicinity are commonly covered with ice before the end of November, and
they are not often released until near the end of April.

The water supply is derived from Craig Brook and from three large and
several lesser springs. The source of the brook is Craig Pond, which
affords a constant supply of exceedingly transparent water, warm in
summer and cold in winter, moderated, however; in both extremes by the
water from the springs, which mingles with the brook in its lower
course, forming about a third of its volume. It is this mixed water
which is mainly used in the rearing of fish. Its temperature ranges
from 34° F. [1.1° C.] to 70°F. [21.1°C.]. The lowest monthly mean in
1893 was 35.8° F. [2.1° C.] in February. The highest was 64.6°F.
[18.1°C.] in August. The total volume is variable, ranging from 875
to 3,000 gallons and averaging about 1,200 gallons per minute.

The difference of level between the source and mouth of the brook is
about 190 feet. The sharpest descent is just above the hatchery and
rearing troughs, which therefore receive well-aerated water. The
conformation of the ground offers good facilities for the distribution
and utilization of the water.

The leading motive in the foundation of this station was the desire to
apply to the Atlantic salmon the system of rearing fish to the age of
at least several months before liberating them. This motive has
determined not only the principal subjects of the work, but also to a
considerable extent the fixtures and methods. The scheme of work was
determined in outline several years before the acquisition of full
title to the premises, and, circumstances rendering it desirable to
enter at once on its development, it became necessary to have recourse
to movable apparatus, pending authority for permanent improvements.

Hence the erection of a series of small troughs in the open air, which
gave such excellent satisfaction that enlargement took the same
direction; and it has thus come about that the rearing operations of
the station down to the present time have been almost exclusively
conducted in open-air troughs. A series of ponds has been constructed,
but with the exception of a few small ones none of them have been as
yet brought into use.

The troughs are for the most part such as are used in the hatchery for
the maturing of spawn, and their form and size have been adapted to the
hatching apparatus which has been in use at the Maine station for many
years. The eggs are developed on wire-cloth trays measuring 12 and one
half inches in width and length, and the troughs are therefore 12 and
three quarter inches wide. Their depth is 9 inches and their length is
10 feet 6 inches. Such short troughs were adopted for two reasons:

(1) It was thought that a greater length might involve the exposure of
the eggs near the lower end to the danger of a partial exhaustion of
the air from the water by the eggs above them;

(2) these short troughs are very convenient to cleanse and to move
about for repairs or other purposes. They are made of pine boards
seven-eighths inch thick. On the inside they are planed and varnished
with asphaltum. When used for rearing fish each trough is fitted with a
pair of thin wooden covers reaching its entire length hinged to the
sides and meeting each other, when closed, at a right angle, forming;
as it were, a roof over the trough. When closed they protect from
predatory birds and other vermin; when open they are fixed in an
upright position, in effect adding to the height of the sides and
preventing the fish jumping out. The time spent in opening and closing
the troughs is by this arrangement reduced to a minimum.

Water is fed through wooden tubes, and the volume admitted is regulated
by slides The exit of the water is through another tube or hollow plug
standing upright near the lower end of the trough, and by its height
governing the depth of the water. The outlet tube is movable and is
taken out in cleaning. A wire-cloth screen just above the outlet tube
prevents the fish escaping.

In a trough of standard size 2,000 fry are generally placed, and to
accommodate the large numbers of fish reared we bring into use
sometimes nearly 200 troughs which are of necessity placed in the open
air. They are arranged in pairs with their heads against the feed
troughs, supported by wooden horses at a convenient height from the
ground. They are given an inclination of about 2 inches to facilitate
cleaning.

The volume of water fed to each trough has varied from time to time,
but is ordinarily about 5 gallons per minute, which renews the water
every four minutes. The ordinary arrangement is to use the water but
once in the troughs, letting it waste into some small ponds in which
yearling and older fish are kept; but there is one system of 52 troughs
arranged in four series, which use in succession the same water. From
these we have learned that young salmon thrive quite as well in the
fourth series as in the first. Indeed, by an actual test, with fish of
like origin and character in each series, the fish reared in the fourth
series were found to grow faster, to an important degree, than those in
the first. This phenomenon probably resulted from a somewhat higher
temperature which the water acquired in passing through the several
series. A like observation has been made on a few salmon maintained for
a few weeks, in the warmer water of a neighboring brook.

As already stated, the activity of the station has been mainly occupied
with Atlantic salmon, but there have been reared each year a few
landlocked salmon and brook trout, and occasional lots of other
salmonoids, such as Loch Leven, Von Behr, Swiss-lake, rainbow, and
Scotch sea trout. All these have received the same treatment. With the
exception of the rainbow trout, they are all autumn-spawning fishes,
and their eggs hatch early in the spring.

The embryos of salmon begin to burst the shell in the month of March,
and the 1st of April may be stated as the mean date of hatching. If the
open-air troughs are in order--and we aim to have them so--the eggs are
counted out into lots of 2,000 or 4,000 each and placed before hatching
in their summer quarters. The water is at that time very cold, the
development of the alevins is slow, and it is not until the latter part
of May that the yolk sack is fully absorbed. June 1 is, therefore, the
date when feeding is ordinarily begun. The growth of the fish is at
first slow, the water being still cool, but is accelerated as the
summer passes away. In October and November, beginning commonly about
the middle of October, most of the fish are counted out and liberated,
but a small number, rarely more than 15,000, being carried through the
winter at the station. The reserved fish are sometimes left until
midwinter in their summer quarters, and with a careful covering of the
conduits and banking of the troughs themselves each with coarse hay and
evergreen boughs it is possible to keep them there the year round; but
for ordinary winter storage there is provided a system of sunken tanks
covered by a rough shed with a constant water supply. These tanks are
molasses hogsheads, securely hooped with iron, sunk nearly their entire
depth into the ground, each with an independent water supply and waste,
the perforation for the latter being near the surface. They have a
capacity of from 100 gallons of water upward, and will carry safely
each 500 to 700 fish in their first winter, that is, just approaching
the age of one year.

This arrangement has answered its purpose fairly well, and in a very
rigorous climate or where the water is very cold it is to be
recommended; but since its construction it has been discovered that at
Craig Brook it is not at all difficult to protect the ordinary troughs
in such a way as to insure their safety from freezing, and their
attendance through the winter is less troublesome than that of the
sunken tanks.

A list of the articles employed for food at the station since its
foundation, if designed to include those used on an experimental as
well as a practical scale, would be a long one, and I will content
myself with naming the following: On a practical scale we have used
butcher's offal, flesh of horses and other domestic animals by the
carcass, fresh fish, maggots; and on an experimental scale, pickled
fish, fresh-water mussels, mosquito larvae, miscellaneous aquatic
animals of minute size.

In the production of maggots we have also made use of large quantities
of stale meat from the markets and some barrels of fish pomace, in
addition to the articles mentioned above.

The butcher's offal comprises the livers, hearts and lights of such
animals as are slaughtered in Orland and Bucksport--mainly lambs and
veals. These are collected from the slaughter-houses twice or thrice
weekly, and preserved in refrigerators until used. The quantity of such
material to be had in the vicinity has been inadequate to our needs and
we have been compelled to look in other directions for food.

The flesh of horses has been used only during the season of 1893. Old
and worn out horses and those hopelessly crippled or dying suddenly
have been bought when offered, and used in the same way as the
butcher's offal; the parts that could be chopped readily have been fed
direct to the fish so far as needed; and other parts have been used in
the rearing of maggots. The season's experience has been so
satisfactory that greater use will be made of horse flesh hereafter.

Next to the chopped meat, maggots have constituted the most important
article of food, and their systematic production has received much
attention. A rough wooden building has been erected for the
accommodation of this branch of the work and one man is constantly
employed about it during the summer and early autumn months. The
maggots thus far employed are exclusively flesh-eaters, mainly those of
two undetermined species of flies--the first and most important being
a small smooth, shining green or bluish-green fly occurring at the
beginning of summer and remaining in somewhat diminished numbers until
October, and the other a large rough, steel-blue fly that makes its
appearance later and in autumn becomes the predominating species,
having such hardiness as to continue the reproduction of its kind long
after the occurrence of frosts sufficiently severe to freeze the
ground.

In outline the procedure is to expose the flesh of animals in a
sheltered location during the day, and when well stocked with the spawn
of the flies to place it in boxes which are set away in the "fly house"
to develop; when fully grown the maggots are taken out and fed at once
to the fish. The materials used for the enticing of the flies and the
nourishment of the maggots have been various. Stale meat from the
markets has been perhaps the leading article, but we have also used
such parts of the butcher's offal and of the horse carcasses as were
not well adapted to chopping; fish, fresh dried or pickled; fish pomace
from herring-oil works, and any animal refuse that came to hand.

Fresh or slightly tainted meat has been used to greater extent than any
other material, and has proved itself equally good with any. Fresh fish
is very attractive to the flies, and when in just the proper condition
may be equally good with fresh meat, but some kinds of fish are too
oily, for instance, alewives and herring, and all sorts thus far tried
are apt to be too watery.

A very limited trial of fish dried without salt or smoke indicates that
it is, when free from oil, a very superior article; it has, of course,
to be moistened before using. Its preparation presents some
difficulties, but in winter it is easily effected by impaling the whole
fish on sticks and hanging them up, (after the manner of alewives or
herring in a smokehouse) under a roof where they will be protected from
rain without hindering the circulation of air; in this way we have
dried many flounders and other refuse fish from the smelt fisheries,
which are conducted with bag nets in the vicinity of Bucksport.

Doubtless a centrifugal drying machine might be successfully used for
this purpose in summer. Pickled alewives, freshened out in water, have
been found to answer fairly well, when other materials are lacking, at
least to give growth to maggots otherwise started. Fish pomace has not
thus far given satisfaction, but seems worthy of further trial.

It is commonly necessary to expose meat but a single day to obtain
sufficient fly spawn; the larvae are hatched and active the next day,
except in cool weather, and they attain their full growth in two or
three days. To separate them from the remnants of food and other debris
was at first a troublesome task. It is now effected as follows: the
meat bearing the fly spawn is placed on a layer of loose hay or straw
in a box which has a wire-cloth bottom, and which stands inside a
slightly larger box with a tight wooden bottom. When full grown the
maggots work their way down through the hay into the lower box, where
they are found nearly free from dirt.

When young salmon or trout first begin to feed they are quite unable to
swallow full-grown maggots. Small ones are obtained for them by putting
a large quantity of fly spawn with a small quantity of meat, the result
being that the maggots soon begin to crowd each other and the surplus
is worked off into the lower box before attaining great size. No
attempt is, however, made to induce the young fish to swallow even the
smallest maggots until they have been fed a while an chopped liver.

In the above methods maggots are produced and used in considerable
numbers, sometimes as many as a bushel in a day. Through September,
1893, although the weather and some other circumstances were not very
favorable, the average daily production was a little over half a
bushel.

They are eagerly eaten by the fish, which appear to thrive on them
better than on dead meat. Having great tenacity of life, if not snapped
up immediately by the fish they remain alive for a day or two, and, as
they wriggle about on the bottom, are almost certain to be finally
eaten; whereas the particles of dead flesh that fall to the bottom are
largely neglected by the fish and begin to putrefy in a few hours. In
the fish troughs there are, therefore, certain gains in both
cleanliness and economy from the use of maggots which may be set down
as compensating the waste and filthiness of the fly-house.

As the growth of maggots can be controlled by regulation of the
temperature, it is possible to keep them all winter in a pit or cellar,
and advantage is taken of this to use them during winter as food for
fish confined in deep tanks not easily cleaned.

The offensive odors of decaying flesh may be largely overcome by
covering it, on putting it away in the boxes, after the visits of the
flies, with pulverized earth, and it is not improbable that by this or
some other method the business may be made almost wholly inoffensive,
but in its present stage of development it is too malodorous to admit
of practice in any place where there are human habitations or resorts
within half a mile of the spot where the maggots are grown.

As remarked above, only flesh-eating maggots have yet been tried. It
would be well worth while to experiment with the larvae of other
species, such as the house fly, the stable fly, etc. There is also a
white maggot known to grow in heaps of seaweed. Should the rate of
growth of either of these species be found to be satisfactory they
might be substituted for the flesh maggots with advantage.

Occasional use has been made of fresh fish for direct feeding. When
thrown into the water after chopping it breaks up into fibers to such
an extent that it is not very satisfactory, and I do not suppose we
shall use it in the future, unless in a coarsely chopped form for the
food of large fish. A few barrels of salted alewives have been used,
and if well soaked out and chopped they are readily eaten by the larger
fish and can be fed to fry, but are less satisfactory with the latter,
and like fresh fish they break up to such an extent that they are only
to be regarded as one of the last resorts.

Fresh-water mussels have been occasionally gathered in the lake close
to the station when there has been a scarcity of food. Those employed
belong almost wholly to a species of Unio which abounds over a
considerable area of soft bottom, under a depth of 2 to 10 feet of
water. Many were taken with a boat dredge; more were scooped up with
long-handled dip nets of special construction. Finally a wide, flat
dredge was made, to be drawn by a windlass on the shore and manipulated
by means of poles from a large boat.

When needed for food the mussels were opened with knives--a great
task--and chopped. The meat is readily eaten by all fishes, and appears
to form an excellent diet. Being more buoyant than any other article
tried, it sinks slower in the water and gives the fish more time to
seize it before it reaches the bottom, a consideration of considerable
practical importance. The labor involved in dredging and shelling is a
serious drawback, but were the colonies of unios sufficiently extensive
or their reproduction rapid enough to warrant expenditure of time in
experimentation; improved methods might be devised, which would put
this food-source on a practicable basis.

During the seasons of 1886 and 1888 some use was made of mosquito
larvae. Near the station is an extensive swamp where these insects
breed in great numbers. From the pools of water the larvae were daily
collected by means of a set of strainers specially devised for this
use. Barrels filled with water were also disposed in convenient places
near the rearing troughs, and were soon swarming with larvae from the
eggs deposited by the mosquitoes on the surface of the water. When near
the completion of their growth, which was only some ten days after the
deposit of the eggs, the larvae (or pupae) were strained out and fed
to the fish. No kind of food has been used this station that has been
more eagerly devoured, and so far as our observation has gone no other
food has contributed more to the growth of the fish; indeed, I am
inclined to put them at the head in both respects. It was found,
however, that the time expended in collecting them was out of all
proportion to the quantity of food secured, and pending opportunity for
further experiment their use was discontinued.

I think it quite possible that an arrangement might be devised whereby
the greater part of the labor might be saved. Perhaps a series of
breeding tanks arranged in proximity to the fish troughs, into which
the water containing the larvae might be drawn when desirable by the
simple opening of faucet, would solve the problem.

Various methods of serving the food have been tried, but at present
everything is given with a spoon. The attendant carries the food with
the left hand--in a 2-quart dipper if chopped meat, in a larger vessel
if maggots--and, dipping it out with a large spoon, strews it the whole
length of the trough, being careful to put the greater portion at the
head, where the fish nearly always congregate. Finely chopped food, for
very young fish, is slightly thinned with water before feeding. At one
time the finest food was fed through perforations in the bottom of a
tin dish; the food was placed in the dish, which was dipped into the
water a little and shaken till enough of the food had dropped out of
the perforations; this practice was laid aside because it was thought
that the food was too much diluted.

In feeding maggots it was, at first, the practice to place them on
small "feeding boards" of special construction suspended over the water
in the troughs and let them crawl off into the water; but whatever
advantage this method may have had in furnishing the meal to the fish
slowly was more than counterbalanced by the extra labor of caring for
the boards and by the offensive odor, and it was abandoned. For use in
feeding fish in a pond a box containing a series of shelves, down which
the maggots slowly crawl, was found sufficiently useful to be retained.

It is the common practice to feed all meat raw except the lights, which
chop better if boiled first, except also occasional lots of meat that
are on the point of becoming tainted and are boiled to save them. All
meats fed direct to the fish are first passed through a chopping
machine. The machine known as the "Enterprise" is the one now in use.
It forces the meat through perforated steel plates. The plate used for
the smaller fish has perforations 2 inch in diameter, and for coarser
work there are two plates 3/16th inch and 3/8th inch, respectively. It
is operated by a crank turned by hand.

Food is given to those fish just beginning to eat four times a day (in
some cases even six times). As the season progresses the number of
rations is gradually reduced to two daily. In winter such fish as are
carried through are fed but once a day. The cleaning of the troughs has
been a troublesome matter, and the subject of much study and
experiment, but nothing more satisfactory has been found than the
following practice: The troughs are all to be cleaned daily--not all at
one time, but as time is found for it in the intervals of other work.
To facilitate cleaning, the troughs are inclined about 2 inches. The
outlet is commanded, as already explained, by a hollow plug.

When this is drawn the water rushes out rapidly and carries most of the
debris against the screen. The fishes are excited, and, scurrying
about, they loosen nearly all dirt from the bottom; what will not
otherwise yield must be started with a brush, but after the first few
weeks the brush has rarely to be used except to rub the debris through
the outlet screen. Owing to the inclination of the trough the water
recedes from the upper end until the fishes lying there are almost
wholly out of water, but, although they are left in that position
sometimes for 10 or 15 minutes, no harm has ever been known to result.

It has been the common rule at the station to count all the embryos
devoted to the process of rearing, either before or after hatching; to
keep an accurate record of losses during the season, and to check the
record by a recount in the fall. When eggs are counted they are lifted
in a teaspoon.

The counting of small fish is effected in this way: The fish are first
gathered in a fine, soft bag-net, commonly one made of cheese-cloth,
and from this, hanging meanwhile in the water, yet so that the fish
cannot escape, they are dipped out a few at a time, in a small dipper
or cup, counted, and placed in a pail of water or some other
receptacle.

This counting is generally preliminary to weighing, and in this case
the fish, after counting, are placed in another bag-net, in which they
are lowered, several hundred at a time, into a pail of water which has
been previously weighed, and the increase noted. With care to avoid
transferring to the weighing pail any surplus water, this is a correct
method and very easy and safe for the fish.

In conclusion, I submit some estimates of cost. In September, 1893, we
fed fry that were estimated at the close of the month to number
238,300. There were also a few hundred larger fish.

From the known total outlay for food, attendance, and superintendence a
suitable allowance is made for the maintenance of the older fish, and
the balance is charged to the fry. By this method we arrive at the
following results:


Cost...................Total........Per fish.
Food                   $155.00      $0.00065
Attendance               99.79        .00042
Superintendence         205.96        .00086
Total                   460.75       0.00193

Applied to the rearing operations of 1891, a similar calculation gives
us this result: The fry that were carried through the season from June
to October, inclusive, cost, for food, attendance, and superintendence,
$0.0081 each; that is, about four-fifths of a cent each for the term of
five months.



ARTICLE VII

NOTES ON THE CAPTURE OF ATLANTIC SALMON AT SEA AND IN THE COAST WATERS
OF THE EASTERN STATES

By Hugh M. Smith, M. D., Assistant in charge of Division of Statistics
and Methods of the Fisheries.

_Bulletin of the United States Fish Commission_, Vol. 14, Page 95, 1894.



In carrying out its most important function--the maintenance and
increase of the supply of food fishes--the U.S. Commission of Fish and
Fisheries, in addition to direct efforts to increase the abundance of
fishes naturally inhabiting our various rivers, lakes, and coast
waters, has given considerable attention to the experimental
introduction of fishes into regions or streams to which they were not
native.

The wonderful success which has followed the planting of shad and
striped bass fry in the waters of the Pacific coast is well known. The
results attending the recent attempts of the Commission to establish
a run of salmon (_Salmo salar_) in some of the large rivers of the
Atlantic coast have been so noteworthy in the case of the Hudson as
to afford reasonable ground for expecting the early inauguration of a
regular fishery, should the present rate of increase in the abundance of
the fish be maintained. Similar striking results may also be anticipated
in all the more northern streams of the east coast, including the
Housatonic, Connecticut, and Merrimac, in which salmon were at one time
found in abundance and are now taken in small numbers, if the ascent
of the adult fish to the headwaters for the purpose of spawning is
permitted and if sufficiently extensive fish-cultural operations are
continued.

The primary purpose of this paper is to record some of the apparent
results of salmon propagation in our rivers as shown by the occurrence
of the fish at points on the coast or at sea more or less remote from
the places where fry have been deposited.

While an interesting and instructive compilation might be made of the
instances of the capture of salmon in the Hudson, Delaware,
Susquehanna, Potomac, and other rivers in which the fish has been
acclimated, such a work is not necessary in view of the notice which
has already been accorded the matter in the public press and in the
reports of several of the State fish commissions, notably the New York
commission.

So much yet remains to be learned regarding the lines of migration of
the salmon to and from the rivers, its winter habitat, the existence of
an "instinct of nativity" which is supposed to impel the return of the
fish to the place where hatched, the extent of the coastwise
distribution of salmon originally belonging in a given river, and
numerous other practical and scientific questions, that the
presentation of any data bearing on the occurrence of the fish outside
of the rivers may be regarded as acceptable and timely.

In an interesting article on "Salmon at Sea," communicated to the issue
of _Forest and Stream_ for February 18, 1892, Mr. A. N. Cheney, the
well-known angling expert and writer on fish-cultural matters, discusses
the question of the whereabouts of salmon after they leave the rivers,
and quotes the following from a previous contribution by himself on the
subject:

"There is a certain mystery about the habits and movements of the sea
salmon, after it has left the fresh-water rivers in which it spawns and
gone down to the sea, that never has been satisfactorily explained. One
theory is that all the salmon of the rivers along a coast may journey
down to the sea, and then move ultimately in one great body southward
along the coast until they find water of suitable temperature, with an
abundance of food, in which to spend their time in growing fat until
the spawning instinct warns them to return, when they proceed
northward, each river school entering its own particular river as the
main school arrives opposite the river month.

"Another theory is that the salmon of each river, as they arrive at its
mouth after descending from its headwaters, go out to sea sufficiently
far to find the conditions of temperature and food which suit them, and
there they remain, separate from the salmon of other rivers, until it
is time for them to return to fresh water. Considering the certainty
with which the salmon of any particular river return again to the
stream of their birth, the latter theory seems the more tenable of the
two."

Another object of this paper is to solicit correspondence from
fishermen, especially those engaged in the coast and offshore
fisheries, concerning the circumstances of the capture of salmon in
their nets, and to bring to their attention the opportunity they will
thus have of increasing the knowledge of the movements of the salmon,
of aiding in the determination of the results of fishcultural
operations, and of ultimately if not immediately benefiting themselves
by supplying information that will conduce to the most effective
application of artificial methods.

To this end it is the intention to send the paper to fishermen engaged
in the mackerel, menhaden, and other sea fisheries, and to operators of
pound nets, traps, and other shore appliances, with the hope that
instances of the capture of salmon may be communicated to this
Commission and notes on the size, condition, movements, etc., of the
fish be furnished.

To aid in the identification of the salmon when caught by fishermen who
have not previously met with the fish, a figure is presented.

In this connection mention may be made of the chinook or quinnat salmon
of the Pacific coast (_Oncorhynchus chouicha_), fry of which have been
extensively planted in eastern waters by the U. S. Commission of Fish
and Fisheries. Up to and including the year 1880, about 12,000,000 fry
were deposited in rivers and other waters tributary to the Atlantic.
While a few relatively large examples have been taken, this office has
no information to show that the attempts to acclimate this species on
the Atlantic coast have as yet been successful. In 1891 a few thousand
yearling salmon were placed in New York waters tributary to the sea.
The possibility of the survival and growth of some of these and of the
large early colonies prompts this reference to the matter and suggests
the publication of the accompanying figure of the species, to afford a
basis for distinguishing the two kinds of salmon, which closely
resemble each other. To further aid in the identification of the two
species the following key has been prepared:

Rays in anal fin, 9; scales between gill opening and base of tail, 120;
branchiostegals (false gill openings), 11 ..........ATLANTIC SALMON.

Rays in anal fin, 16; scales between gill opening and base of tail,
150; branchiostegals, (false gill openings) 15 to 19..........PACIFIC
SALMON.

Numerous instances might be cited of the taking of salmon in the waters
of the Atlantic coast in recent years. Their occurrence in the traps
and pound nets is in fact so common that it would hardly be entitled to
notice at this time were it not for the circumstance that in regions in
which salmon were already known there has been a decided increase in
the number observed outside the rivers, and that the fish is now being
taken in localities in which it was not previously found.

Instances of the capture of salmon in the coast waters of Maine are
naturally numerous, and without significance so far as the purposes of
the present paper are concerned. The existence of two important salmon
rivers, the Kennebec and the Penobscot, affords an easy explanation of
the presence of salmon on the shores of either side of the mouths of
those streams. In the report of the U. S. Commission of Fish and
Fisheries for 1873-73 Mr. Charles G. Atkins, now superintendent of the
salmon-rearing establishment at East Orland, Me., and an authoritative
writer on the Atlantic salmon, contributes some notes on its occurrence
in the sea adjacent to Penobscot Bay and at Richmond Island, near
Portland. These cases, however, have little bearing on the subject in
hand, as Mr. Atkins suggests in a recent letter.

A special inquiry, personally conducted on Matinicus, Monhegan, and
other islands lying far off the Maine coast, and special researches
there made with appropriate apparatus, would doubtless disclose many
interesting facts regarding the salmon of a practical and scientific
nature. A few apparently unrecorded notes concerning the fish among
islands off the island of Mount Desert may be given, which are probably
indicative of what may be expected in other sections.

Mr. W. I. Mayo, who has fished herring brush-weirs at the Cranberry
Isles for many years, and is a life-long fisherman in that section,
communicates the intelligence that salmon were first observed about
those islands in 1888. On June 17 a salmon, weighing 20 pounds, was
taken in a herring weir, and on June 19 another, weighing 19 pounds,
was caught. On July 14 of the same year 6 salmon, weighing 4 to 6
pounds apiece, were secured, but were liberated on account of their
size. During the four years intervening between 1888 and 1893 none was
taken around these islands, but in June of the latter year they
reappeared. On June 11 a salmon weighing 15 pounds was taken in a weir,
and on various occasions during that month a number weighing 12 to 15
pounds each were caught by boat fishermen on trawl lines fished for
cod.

The trawls were baited with herring and set on the bottom in rather
deep water. Mr. Mayo states that these were the first salmon ever taken
on trawl lines in that region. The Cranberry Isles lie off the
southeastern part of Mount Desert Island, and are about 25 miles east
from Penobscot Bay and about 35 miles in a straight line from the mouth
of the Penobscot River.

On the Massachusetts coast salmon are now regularly taken each year at
most of the important pound-net and trap fisheries. The largest numbers
are caught in Cape Cod Bay. A State law prohibits the taking of salmon
in nets and requires the return to the water alive of all fish so
caught. This makes the fishermen diffident about giving information and
renders difficult the determination of the abundance of the fish. On
June 6, 1879 the _Cape Ann Advertiser_, of Gloucester, contained the
following note:

"A 10-pound salmon was taken from a weir off Magnolia Thursday night.
This is the first salmon caught off Cape Ann for over thirty years. On
Saturday morning three more large salmon were taken. The fishermen are
highly elated at the prospect of salmon-catching."

During the past five or six years a few salmon have been taken almost
every season in the vicinity of Gloucester, the average annual catch
being 4 to 6 fish. In 1888 the State fish commissioners reported the
capture of 18 salmon in traps at Manchester and Gloucester. In 1893, 13
traps in the neighborhood of Gloucester took 5 salmon.

In December, 1891, a salmon weighing 28 pounds was caught on a cod
trawl line set near Halfway Rock, off Salem Harbor, Mass.; Mr. William
Dennett, of Gloucester, who secured the fish, reports that he sold it
for $46. Mr. Samuel Wiley, of Gloucester, in September 1893, caught a
salmon at sea off Gloucester on a trawl line fished for hake. These are
the only instances that have been reported of the capture of salmon on
a hook in the vicinity of Gloucester. As the trawl lines in question
were set on the bottom at a depth of 20 or 25 fathoms, the fact that
these two fish at least were swimming on the bottom may be considered
established.

Relatively large numbers of salmon have recently been taken in the
pound nets of Cape Cod Bay. Capt. Atkins Hughes, of North Truro, one of
the best-informed and most reliable fishermen in the region, informs us
that at North Truro, the principal pound-net center in the bay, about
70 large salmon have been annually caught for two or three years. The
fish are taken throughout the entire pound-net season, but are most
common in the early part of the fishing year (May and June). Some fish
weighing 25 to 28 pounds have recently been caught. For two or three
years he has noticed in the pound nets in October large numbers of
young salmon, about 6 inches long; each net probably takes one or two
barrels of these annually; he had never observed these small fish
before in his long fishing career in that region. In 1893, however,
rather less than the usual number of large salmon were observed, and
very few of the small fish mentioned were taken.

Mr. Vinal N. Edwards, of the Fish Commission station at Woods Holl,
Mass., states that in September, 1892, when he visited the Cape Cod
region, a great many salmon were being taken in the pound nets. They
weighed 4 or 5 pounds apiece. At one pound-net fishery in Provincetown
he saw enough salmon to fill two sugar barrels.

Concerning the occurrence of salmon in the Cape Cod region, Mr. Cheney,
in the article previously mentioned, quotes Hon. Eugene G. Blackford,
of New York, as follows:

"We get every winter a few fish from the Atlantic coast that are
evidently part of the schools of fish that run up into the Kennebec,
Penobscot, and other eastern rivers. During November and December we
had about 15 to 20 fish, weighing from 12 to 24 pounds each, that were
caught in the mackerel nets in the vicinity of Provincetown and North
Truro, Mass. These nets are set out from the Cape in very deep water.

"During the past two or three weeks we have received several specimens
of very handsome salmon from Maine, where they have been caught by the
smelt fishermen in their nets when they have been fishing for smelt. I
think these catches of salmon go very far to prove that the schools of
fish are not very far off from our shores during the time that they are
not found in the rivers, and that both shad and salmon, when they leave
our rivers, do not go either east or south, but are within 100 miles or
so of the rivers where they were spawned. The fish are remarkable in
being in splendid condition and perfect in form and appearance."

Mr. Cheney thinks the salmon taken off Cape Cod belong in either the
Merrimac River or the Penobscot River; and, as in the year in question
fish were being caught at the mouth of the Penobscot at the same time
they were being taken at Cape Cod, he thinks it probable that the fish
in the latter region were from the Merrimac.

In the pound-net fishery of the northern coast of New Jersey the recent
capture of salmon has been a subject of much interest to the local
fishermen and of considerable importance to fish-culturists and
naturalists.

For a number of years a few salmon have, from time to time, been taken
in Sandy Hook Bay, but within the past two or three years there has
been an increase in the number caught. At Belford, the principal
fishing center in the bay, Mr. M. C. Lohsen states that some have been
taken weighing from 12 to 40 pounds, and that in the spring of 1893
more than the usual number were caught in the pound nets. Mr. Harry
White, of the same place, never took salmon in pound nets prior to
1891; he secured 1 that year and 2 in 1892, but failed to get any in
1893. Other fishermen, however, obtained one or two fish. The average
weight of the salmon taken here is 12 to 15 pounds; the largest caught
by Mr. White weighed 17 and one half pounds. Small ones, weighing half
a pound each, are sometimes observed. It is only during the month of
May that salmon are noticed on this shore. One weighing 16 pounds,
taken in a pound net at this place in 1891, sold for $11; the following
year two, with a combined weight of 23 pounds, sold for $15.95.

In the vicinity of Long Branch, we are informed of the recent capture
of a number of salmon in the pound nets set directly in the ocean. Mr.
Ed. Hennessey, of North Long Branch, reports that in 1892 two salmon
and in 1893 one salmon were taken in his pound; they weighed from 10 to
15 pounds each. In April, 1891, Messrs. Gaskins and Hennessey, of the
same place, secured a salmon in their pound; this was the only one they
ever took. Messrs. W. T. Van Dyke & Co., pound-net fishermen of Long
Branch, communicate the following instances of the taking of salmon by
them in 1893: May 10, 1 salmon weighing 9 1/2 pounds; May 11, 1 salmon
weighing 13 1/2 pounds; May 17, 1 salmon, and May 18, 1 salmon, weight
not given. Messrs. West and Jeffrey, pound-net fishermen at Long
Branch, report that in 1892 they caught 2 small salmon.

In 1893, 3 fish were taken, as follows: May 10, a salmon weighing 19
pounds; May 18, 1 weighing 12 pounds; May 20, 1 weighing 10 pounds. Mr.
Henry F. Harvey, who fishes a pound net at Mantoloking, N. J., about 35
miles south of Sandy Hook, communicates the information that in May,
1893, 2 salmon weighing 10 or 12 pounds each were taken at that place.
None had ever before been caught there.

One of the most interesting facts at hand concerning the oceanic
occurrence of the salmon has been noted in a previous paper in this
Bulletin, (*) but may be again referred to in order to make the present
article more complete. Instances of the capture or observation of
salmon far out at sea or even at relatively short distances from land
are very rare and are entitled to publication whenever noted.

About April 10, 1893 the mackerel schooner _Ethel B. Jacobs_, of
Gloucester, Mass., was cruising for mackerel off the coast of Delaware.
When in latitude 38 degrees, at a point about 50 miles ESE. of Fenwick
Island light-ship, the vessel fell in at night with a large body of
mackerel, and the seine was thrown round a part of the school. Among
the mackerel taken was an Atlantic salmon weighing 16 pounds, which
Capt. Solomon Jacobs, who was in command of the schooner, sent home to
Gloucester. Capt. Jacobs informs us that the fish was fat and in fine
condition. Some of the crew told the captain that there was another
salmon in the seine, but it escaped over the cork line as the seine was
being "dried in." The light-ship mentioned is about 10 miles off the
coast, so the place where these salmon were taken was about 60 miles
from the nearest land.

The foregoing is the only instance known to this Commission of the
capture of salmon so far at sea on the coast of the United States or of
the taking of salmon in a purse seine with mackerel under any
circumstances. Capt. S. J. Martin, the veteran fisherman of Gloucester,
Mass., has never known of another such occurrence, and a special
inquiry conducted by him among the mackerel fishermen of that port
failed to disclose the knowledge among them of a similar case.
