ches below the surface and the little fish allowed to swim out into
the box.

As soon as the yolk-sacs of the alevins are absorbed the little fish
cease to be alevins, and are called "fry."

The alevin stage was that in which the fish give least trouble, the
stage I am now describing is that in which they give most. They must be
fed frequently--at least four times a day. "Little and often" is the
maxim which should rule the actions of the fish culturist with regard to
feeding the fry. If he can only feed his fish four times a day, he must
spend some time on each of these four occasions. The food must not be
thrown in all at once. If this be done the little fish will not get half
of it; the other half will sink to the bottom.

The food should be introduced in small quantities at a time, and if the
amateur has several boxes he should put a little food into each in
succession, coming back to the first when he has put some into the last,
repeating this operation at least half a dozen times. The less he puts
in at each time, and the oftener he does it, the better. The ideal plan
would be to put a very small quantity of food in each time, and to go on
doing this at intervals of from five to ten minutes all day.

Livingstone Stone says, "You need not be afraid of the young fry's
eating too much." And again, "I never knew any healthy young fry of mine
decline eating but once, and then I had fed them incessantly for two
hours, at the end of which time they gave up, beaten." Personally, I
have found no limit to the time that the fry will continue feeding. I
have kept on putting small quantities of food into a rearing box for a
whole afternoon, and I was tired of feeding before the fry were tired of
eating. My reader will infer from this that I believe that the fry
cannot be over-fed, and this is to a certain extent true. If finely
divided food is given in such small quantities that practically none of
it sinks to the bottom without their having a fair chance at it, I
believe that in a box containing only a couple of thousand fry, it would
be found that they never stopped feeding during the whole day. If,
however, too large pieces of food are offered to the little fish, many
of them are likely to be choked and to die, from trying to swallow a
piece a little too big for them.

The amateur will observe that shortly after the fry have been let out
into the box and are feeding freely, they will separate into two more or
less dist
