In the matter of replenishing the streams
with most desirable game and food fish
science comes to the aid of ma
are ripe until the fry have reached a
size of from n to inches. A description
of how these 1900, 900 odd trout were OBJ
tanned and cared for until distributed will
give comprehensive idea of the general
process of artificial piscatorial propagation.
All the eggs from which these fish were
Matched were obtained from Lake Tahoe.
The parent fish were caught at the mouths
of Taylor and Blackwood creeks, seines
being used at the former and traps at the
latter. The work of capturing them began
on the 18th of April and continued until
the Goth of June, the period during which
the trout leave the lake to run up the
creeks to spawn.
AS the fish are caught the males and
ent tanks, which are fastened alongside
the spawning scow. The ripe females are
stripped of their eggs by light pressure
along their sides, and the males are SINH
larly operated upon for the expul-
sion of their mills. The fertilization
of the eggs is then accomplished by mix
ing the eggs and mills in pan containing
no water. While in the ordinary course
of nature but per cent of the eggs are
fertilized, by the artificial method the re-
markable result is obtained of SO per cent
of the eggs being made productive.
Should fish prove to be unripe it is put
into a special tank and operated upon
until the desired result is obtained. Des-
pite the handling that the parent fish are
thus made to undergo the loss is but one
half per cent of the total capture.
All the eggs as rapidly as they are fer
tilized are removed to the hatchery at
Tahoe City, where they are placed in wire
baskets, the meshes OF which are just too
small to allow the eggs to drop through
into the troughs of running water in
which the baskets are submerged. But
as soon as the outer shell of the
egg breaks, which occurs in from
perature of the water, the embryo fish,
which are now known as alveus, drop into
the trough. Before the eggs break at all

become the eyes s and the eggs are
They remain alveus from ten to fifteen
days, according to the temperature and

The fry do not begin to feed until
they are eight days old. They are
at first given sweet curds and later
this food is alternated with raw liver and
meat finely ground. AT first they show
great timidity when the food is placed in
the water, but they soon get. to learn that
any foreign substance placed in their home
is for them to feed upon, and they then
display voracious appetite. Distribution

OF the ATE, 900 eggs originally placed in
the Tahoe hatchery $500, 600 were shipped
to the Sisson hatchery after they had be-
come eyed. The greatest care is exercised
in the transportation of the partly devel-
oped eggs, specially designed cases, meas
uring two feet each way, being used. In
these eggs have been successfully shipped
to France and to Australia. Each case
holds about LIZ, 900 eggs.
The fry are transported in twenty-gallon
cans, each holding from 5000 to 1000 fish,
and during transportation require the con-
slant care of an attendant. whose
duty it is to aerate the water by
every seven minutes and allowing it
to flow back into the can. In making the
trip from Sisson to Fosters, in San Diego
County, r. w. Requa, the shipper, was
forced to 60 without sleep for sixty hours
in order to properly perform his duties
and ensure the arrival OF his fish in good
condition. On one occasion w. II. Shelby

ery), in taking a consignment of fry to
San Raroordino County was forrod IN
