The Artificial Reproduction Of
Fishes.

Theodatus Gsrlick, of Cleveland, Ohio,
in connection with Prof. Ackley, have been
making some experiments in the lately re-
vived science of breeding fish by artIf,ial
means. He says:
We determined to select the speckled
trout Salnso frontinaIis) for our first ex-
pertinent Accordingly, in the month Of
August last, started for the Saut Ste. Ma
fEie, with the purpose of obtaining the parent
fishes. while Prof. Ackley was preparing a
suitable place for their reception, by build
ing dam across very larry spring OF water
on his farm, some two mites from Cleve-
land.
The number ofeggs produced by sin
gle female trout in one season has been va
riously stated by.different writer's, but it is a
moderate statement to say that it is many
thousands. word TO those who may
wish to make the experiment, as to my man
ner OF proceeding. ..a. ....,.
partially filled the eartheL vessel with
water, and taking the female in my left
hand, and making gentle pressure on her
abdomen with my right, the eggs were
forced into the earthen vessels containing
the water; the male was treated in precise
y tn. same manneI, forcing the spermatic
Auid into the same vessel; the appearance
OF the eggs vas almost Immediately chan
ged from their bright golden orange color
to tie transparent yellow; they were then
placed nrunning waer with the vessel con-
tainr them.
The attempt should only be made when
the eggs are mature; to be certain in this
it will be best for the beginner to take the
parent fishes when engaged in deposltng
he eggs. After the eggs are forced into
the vessel containing the wafer, they ShouIl
be stirred about little, the water poured
off, and the Vessel filled again before the
spermatic fluid IS added, after which the
water should second time be agitated
in order that it may come in contact with
all the eggs; this is necessary to the impreg-
nation ot all of them. They should then
be placed where they have running water
constantly passing over them. This must
be done by having series OF boxes partly
| filled with coarse sand and gravel, each
( placed below the other in the form of IA
stairway, the water passing from the first
/ boxEo the second, and SO on. lt would
also be we'll to have the bottoms Of The box
es pierced with small holes in order to pre-
Fvent the sediment from accumuatlng,
which is very destructive to the eggs.
These general rules, il followed, will be
sure to crown the effort with success.
The successful experiments OF MeSsrs
Remy and Gehin OF France, in the artificial
reproduction of certain kinds OF fishes will,
without doubt, be repeatedly made in this
and other countries, and with the same sat
isfactory results.
Thc immense advantages resulting from
this discovery, particularly IN countries
aboundinL with such 4 variety and extent OF
inland waters as our own, can hardly be eS'
timated.
Such streams as are not suited TO tht
trout can be stocked vita other choice warn
cites of fish with the same ease. ...,.,
Every one who may be 50 fortunate as
to possess spring of water OF moderate
size rear this charming fish in great
numbers, and the streams that have been
depopulated by the untirng zeal of the an
gler, can be replenshed with little trouble
and at q small expense.
