Abstract

Examination of 510 stomachs of Sacramento perch from five localities showed that they feed primarily by picking insect larvae and snails from the bottom and aquatic plants or by capturing zooplankton, fish, or emerging insects in midwater. The diet varies with season and size of fish but no daily feeding rhythms were found. Similarity of their diet to that of bluegill indicates that Sacramento perch may have been eliminated from their native habitat through competitive interactions with bluegill.
