Most fish don't
spawn
unless the
water
temperature
is
within
rather narrow limits. To
find the duff erent
temperatures.
a surface
tempera-
ture
meter,
such as the
EDT-20 is a valuable
aid to
your
boat.

provides
an
extremely
quick response

water
spawning temperatures
for various
species.
Trout can't survive
in
streams
that
get
too
warm. Bass and other
fish
eventually
die out
when
stocked in lakes that remain
too cold
during
the summer.
While some fish
have
a wider
temperature
tolerance
than
others,
each
has a certain
range
within
which it tries to
stay.
Schooling
fish
suspended
over
deep
water lie
at
the level that
provides
this
temperature.
We assume
they
are the most
comfortable
here.
