The Feeding Ecology Of The Black And White Crappies In Beaver Reservoir, Arkansas, And Its Effect On The Relative Abundance Of The Crappie Species
Stomachs of black and white crappies (Pomoxis nigromaculatus and P. annularis) collected during the early impoundment (1964-1967) and the late impoundment (1969-70) periods from Beaver Reservoir were analyzed.
