Comments on General Food Habits
The eyes of rock bass have considerable adaptive movement mostly along the rostral-caudal axis, which is associated with feeding on organisms picked up along the bottom *788*. They consume algae *788*. They are a bottom feeder *835*. In an Ontario study, Cladocera are most important all year for age 0 fish. For age I fish, Anisoptera nymphs are important in May and September, and amphipods are important in August and October. Age II fish show Anisoptera nymphs important from May to September, with amphipods and isopods important in October and November, respectively. In age III fish, Anisoptera nymphs are important in May and June, and August-October with decapoda important in July and November. In age IV-V fish, decapoda are important in May, and from July-September, with Anisoptera nymphs important in June, and from October-November. For age VI-X fish, decapods are important year round *6472*. It appears that seasonal changes in the diet can be linked to major population buildups of particular prey items *6472*.
Comments on Adult Food Habits
Adults take mainly crayfish and fish *1195,1547,1125,4205*. Adult and immature aquatic insects make up the bulk of the diet *1187*. Other foods include Anisoptera *1125,5282*, Hydracarina *1125*, and Zygoptera nymphs *6472*.
Comments on Juvenile Food Habits
The juveniles consume mainly zooplankton and small aquatic insects *1195,1547,1125*.
