Comments on General Food Habits

The food is primarily aquatic crustaceans and insects, fishes of the minnow, and shad families, some echinoderms *3300,3302,3305*, also eat zooplankton, fish eggs, fish fry, as well as adult fish *1123*; consume adult and larval aquatic insects and occasionally terrestrial insects *1123,3305,2572* Fish most important to pre-spawning males, insects most important to pre-spawning females; fish 65-66% of diet for post- spawning males and females *5297*. In Tennessee, little feeding occurs in winter *3297*. In Arkansas, winter diet consists mainly of fish, especially shad; also Chironomids, Cladocera, and Chaoborus. Spring diet is mainly Centrarchids, Cyprinids, crayfish, and crustaceans. Summer diet is mainly shad, Centrarchids, crustaceans, and insects. In the Fall, fish account for 99% of diet by weight; included shad, Centrarchids, and silversides, also ate crustaceans & Entomostraca. *5298*. White bass are opportunistic feeders; they form large schools near the water surface, moving in search of prey; they are sight feed- ers, whose ability to feed may be impaired by excessive turbidity; young white bass feed on benthic invertebrates, zooplankton, and larval fish, selecting larger food items as they grow; dietary importance of fish increases at a size of about 40mm; adults typically piscivorous, but will shift to macroinvertebrates or even plankton when forage fish are depleted; white bass grow best when young Percids, Centrarchids, or Clupeids are plentiful; shad (especially threadfin) and alewife are the preferred fish, and white bass production is high where large popula- tions of these species exist *PML 82, 4205*. Adults in Claytor Lake feed primarily on alewife, black crappie, and crayfish *4205*.

Comments on Adult Food Habits

The adult changes to mainly a fish diet at a small size *1123,1140,2572,3295*. The diet includes zooplankton and insects *3305,3308* In an Ohio study, crustaceans made up 61.5% of the diet, with 26.3% fish, and 11.6% water boatmen and midges *1123*. In Wisconsin, Daphnia comprised the bulk of the diet for age II-IV; age V relied more on fish *3305*. Other refer- ences *3305,5962,5927*.

Comments on Juvenile Food Habits

Juveniles ate mostly zooplankton, (Copepods and Cladocerans), insects *1123, 1140,2572,3295*; also fish eggs and fish fry, particularly shad and minnows *3302,3308* In WI, Daphnia comprise bulk of diet *3305*. In Tennessee, fingerlings ate mainly insects and fish *3297*. Other ref- 5962,5928*; juveniles feed on larval centrarchids *CPC3*.

Comments on Larval Food Habits

Larvae ate primarily zooplanktivorous *1123,3302,3295*, mostly copepod nauplii of Cyclops and Diaptomus *3308*. In a study at Lewis and Clark Lake, larvae were size-selective in food habits *6017*. In Kentucky, stomach content analysis that postlarvae 7-12 mm standard length mainly ate prolarval carp. Frequency of occurrence of zooplankton in diet in- creased steadily from 20-100% as postlarvae grew from 6.5-13 mm *5061*.
