the eggs are in proper condition they
will flow readily. la this way there are
extracted from three to FIVE thousand eggs
from each fish. This having been done
with the female, the male is served in the
same manner, milk instead of eggs being
extracted. The quantity of milk necessa-
ry is very small, fifteen grains being sufn-
Gent to impregnate ten thousand eggs.
The eggs and milk remain in contact Tor
short time when they are removed to the
Matching boxes, the bottoms of which are
we'll covered with gravel. The Matching
process is then begun, and is accomplished
in from sixty to ninety days, according to
the temperature Of the water. The best
temperature being from 45 to so degrees,
every degree colder or warmer makes SIX
days difference in Matching. Daily chang
es in the appearance of the egg can be
seen in the Matching boxes, and proves a
very interesting study. The egg is about
the size of a small pea, but gradually
grows larger. About the tenth day fine
dark line is observed in the egg-shell; this
is the backbone of the future fish. AS
this line increases, two black specks ap
pear, which afterward prove to be eyes
| When Matched nothing can be seen with
the unAssisted eye but two exceedingly
bright spots, nearly equal to the bright
ness of diamonds. By and by is observ
able a sack suspended from the throat
this sack is absorbed into the body of the
young fish, a process requiring about fifty
days time. Up to the time of it's .disap'
pearance no food is required, as the sack
contains sufficien nutriment for the young
fish.
At three months old the troutlet is
about one and one-half inches long; they
are then regularly fed. Their, food cou
sisting of curd, beef's liver and heart
chopped exceedingly fine. Great care is
required in, feeding the young fish at this
stage; it is very Necessary they should
have all the food they will eat, but they
should not have any food left, as it would
decompose and make the water foul, and
thus become a positive injury to them.
When six months old they are. about
three inches in length, when year old
they are removed to other apartments tc
make room for the smaller fry, and when
they have reached the age of two years
they are capable of caring for themselves,
and also ready for the anglers hook.
The art Of artiftially formulating fish is
not Of modern discovery it was known as
early as the fourteenth century. The Sc.
cret has been twice lost and twice reds
covered, and it's rediscovery in both in
stances was due to the fact that the fish
cries were becoming reduced, and almost a
total failure Of the oyster, mussel, and
other fish were felt. 1t became necessary
to restock their streams in some way, but
no very great success was met with until
the year 1912 about that time the gov
eminent of France took hold of the mat
ter and established the great fish farm at
Huningue. Since that time other govern
ments have investigated and examined the
subject of fish culture to such an extent
that fish farms have sprung up all ovel
Europe, and our own rivers are rapidly
becoming restocked with many varieties
| of excellent table fish.
