surface temperature was
associated with major fish
movement.

|

An intensive creel census
of anglers showed that the
per-hour catch rate of black
bass rose between major
movement periods,  in-
dicating that fish movement
and the lack of angler
success are related.

Most fish movements
occurred in daylight hours
and were associated with
water surface temperatures
between 52 and 75 degrees
Fahrenheit.

Smallmouth bass traveled
the farthest from the release
site, with some fish going
more than 3,000 feet.

Largemouth bass seldom
ventured more than 1,200
feet away.
