Stomachs and intestines of 89 river otters (Lutra canadensis) collected in eastern Arkansas during the trapping seasons (December- January) of 1978-1983 were examined for food remains. Fish (primarily centrarchids, catostomids, and clupeids) dominated the diet (71.2%). The next most abundant prey was crayfish (18.3% of the diet). Other foods included gray squirrel (Sciurus carolinensis), wood duck (Aixsponsa), snakes (Thamnophis proximus), frogs (Ranidae and Hylidae), and beetles (Coleoptera).
