Food Of The Black Bullhead (Ictalurus Melas) In A New Reservoir
Stomach contents of black bullheads (Ictalurus melas) collected from inshore areas of newly impounded Beaver Reservoir by electroshocker revealed distinct differences in diet between periods of relatively stable water levels and rapidly rising water level.
