SUMMARY AND CONCLUSIONS.
_
have little fear on this account, however loudly its doom might
be pronounced.
—
_
In areas coristantly harassed there can be ne doubt that the ;
shes become more wary and thus more difcult of capture.
:
A tiny laiwal or post—larval cod will avoid the forcepS intended
to capture it, and it is very probable that the adults will move Î
from ground that is constantly shed.
The same holds with all
,
the food-shes.
Hence when shermen ndthat their captures
—'on what was rich ground—seriously diminish, such may be
due to increased wariness as well as to decimated ranksl.
Marine
shes differ in habits from fresh—water forms, suCh as the trout
in streams.
Instead of from day to day frequenting nearly the
same spot with snouts directed to the current, or hiding under
î
the same stones or ledges, the majority of the oceanic round shes
-
roam hither and thither in vast swarms, consorting with those :
of a similar size and bound tono lOcality, for their food is
Ë
universally distributed.
Even the more sedentary at sheS
_
in their life—cycle often show many changes of habitat, and
additional informatiOn has lately been given by Dr C. G. J.

Petersen from the Limfj ord1 into which the young plaice yearly
migrate from the North Sea, and are shed up without achance
:
of returning in adult life to the open ocean and of reproducing
_
their species.

.
The larger forms of the food—shes for the most. part are
_
thînned for the time in areas of the open sea closely shed, but
_
‘
the shes are not extirpated, and if circu'mstances are faV—ourable

_
they, as a rule, repeople the dep1eted waters.
There are
differences howeverin regard to Species. Some, such as the
