few at a time, in a
landing-net from the travelling can, and then, instead of putting them
straight into the water, putting them into a bucket of salt and water
for a short time. Sea water is of course better if it is available. This
does away with any risk of their developing fungus on the spots which
have very likely got bruised during the journey.

The yearlings are best taken from the rearing ponds by netting them. A
net which is more than broad enough to go across the rearing pond is
necessary. Too many should not be taken out at a time in each haul of
the net, as they are thus more likely to be injured or dropped on the
ground. The amateur should not forget, that though the little fish will
stand a good deal of moving about as long as they are in water, they are
likely to be killed, or at least severely injured, by a shock,
particularly if that shock is sustained while they are out of the water
for a second or two during their being moved from one place to another.

If the amateur intends to keep any of his yearlings longer than
December, he will have to make a larger pond. This pond need not be a
long, narrow one like those in which the fry were kept. Though the fish
of course still require a sufficient supply of well-aerated water, a
larger pond without the same marked current through it will do perfectly
well. They must be well fed, and if any grow markedly bigger than the
rest these should be separated. If they are not well supplied with food
they are very likely to try and eat each other, that is to say, the
largest will try to eat the smallest.

CHAPTER XI

THE REARING OF THE RAINBOW TROUT, AMERICAN BROOK TROUT, AND CHAR

As the methods used in hatching out the ova and rearing the young fish
are very similar in the case of different species of trout to those I
have already described in dealing with the common trout (_Salmo fario_),
I will confine myself to pointing out the most marked differences in the
habits of such species as are suitable to our waters, and which are
likely to be of use to the fish culturist. The salmon- or sea-trout will
be dealt with under salmon.

First and foremost among the trout, excluding of course our own brown
trout, I put the rainbow trout (_Salmo irideus_). There are several
varieties of this species, but that which is now being so freely
introduced into many waters in England is the McCloud River rainbow (_S.
irideus_, var. _shasta_). As I have before stated, th
