Comments on General Food Habits

Initial feeding of the larva required a concentration of 1864 nauplii/l *2545*. Early instars of copepods were preferred up to 10 mm length *795*. In South Carolina, they feed heavily on mayfly nymphs in the spring, and take Clupeio fish almost exclusively during the rest of year *5427*. In a California study threadfin shad most were most important from April-November *5649*. They are a predaceous generalist and are usually piscivorous after the early juvenile stage *4205*.

Comments on Adult Food Habits

In Oklahoma reservoirs, gizzard shad were 83.4% of the diet in a reservoir, and 84.6% of the diet in tailwater *5079*. In a California lake, threadfin shad were 94% of the diet *5649*.

Comments on Juvenile Food Habits

In a California lake, threadfin shad made up 45% of the volume of the diet *5649*. In Oklahoma culture ponds, bass 10-30 mm standard length ate mainly copepods, and bass 30 mm ate more Cladocera and insects. Fish were not included in the diet until the bass reached 69 mm, and were not an important part of the diet until the bass were 90 mm *5678*. In Virginia culture ponds, Cladocerans, copepods and insects were important, and Cladoceran abundance in the stomachs increased when the bass were 30-40 mm total length *5716*. The young feed on a variety of worms, small crustaceans, insects and fishes *4205*.

Comments on Larval Food Habits

During the early instars, copepods are preferred up to 10 mm *795*. At the 10-30 mm size class they take adult copepods, Cladocerans, and insect larvae *795*. 30-80 mm size Cladocerans and insect larvae make up the major portion of the diet *795*. At 10-100 mm in size the most important food items are insect larvae *795*.
