Rainbow trout (Salmo gairdneri) were introduced into Lower Abbey Pond, South Dakota, at a stocking rate of 772/ha in June 1977. Sampling was begun in January 1978 to determine food habits and growth of the fish. Trout and environmental samples were taken at 10 day or monthly intervals depending upon the season. A linear index of food selection was calculated and growth data was analyzed using the SHAD computer program. Food habits were determined for 159 rainbow trout collected from January 1978 to October 1978. Stomachs contained a total of 5,700 food organisms with major constituents by number being notonectids (35.0%), dipteran larvae (31.2%), corixids (7.0%), and fathead minnows (Pimephales promelas) (1.2%). Volumetrically, notonectids comprised 37.7% of the total volume of organisms, fathead minnows 16.8%, dipteran larvae 9.9%, and decapods 8.1%. Growth of the trout was better than in many areas of the country and was closely comparable to other trout ponds in the region.
