it is better not to leave
anything to chance and make sure of being on the safe side.

As was the case with the fry during the whole of the earlier part of
their lives, the yearlings will divide into two more or less separate
packs, though the fish may have been separated several times before in
order to divide those which kept at the head from those which kept at
the lower end of the pond. Those trout at the lower end must be coaxed
to the upper end as much as possible, care being taken when feeding that
all the fish get a fair share of food. Should any of the fish remain
obstinately at the lower end, and those at the upper end outgrow them to
a marked extent, the smaller ones must be again separated from the
larger.

When, in September or October, the little fish have grown active and
strong, they may be turned out into the water they are to occupy for the
rest of their lives. There is really no reason why, if they are
well-grown and strong, they should not be turned out in August if the
water they have to be taken to is quite close to the rearing ponds, but
if they have to be carried any distance, it is better to keep them in
the rearing ponds for a few weeks longer, till the weather gets cool
enough to make it quite safe to allow for a possible delay in the
transit.

The turning out of the fish requires some little care. I have seen fish
which had been sent by rail, poured out with the water contained in the
cans, in as hurried a manner as possible. Though of course it is
important to get the fish out of the cans used for transport as soon as
is compatible with safety; still, undue haste in this operation is
likely to do much harm. Young fish of any kind require delicate
handling, and young trout particularly. The cans should, when possible,
be partly emptied, and some water from that into which they are to be
turned put into the can. This is of course not necessary if the rearing
ponds are supplied from the same source as the water into which the fish
are turned. The cans should then be partially immersed in the water, and
the edges brought gradually below the surface. This allows the fish to
swim out of the cans of their own accord, and the few which will not go
out may be forced to do so by gently turning the can upside down.

It is a very good thing to give each of the fish a dose of salt before
turning them out, particularly if they have travelled any distance. This
is easily managed by catching the fish, a
