Food habits of yellow perch, bluegill, and black crappie were studied during 1970 and 1971 in Abbey Pond, South Dakota. Aquatic insects, zooplankton, mollusks, and fish were the most frequently consumed food items by the three species. Yellow perch led primarily on aquatic insects, zooplankton, and mollusks. Aquatic insects were dominant (by volume) in 40.0 and 61.5 percent of the samples respectively for the two years. Zooplankton, mollusks, aquatic insects, and bryozoans were the dominant food items by volume of adult bluegills. On an annual basis aquatic insects were the most important food item in the diet. Adult black crappies fed primarily (as indicated by number and by volume) on zooplankton and aquatic insects. Zooplankton were fed upon regardless of their availability. Daphnia galeata was positively selected while Bosmina longirostris and both cyclopoid and calanoid copepods were selected against by all three species of fish. With the exception of Daphnia parvula, which was positively selected by adult black crappies, the smaller cladocerans were generally selected against.
