Stomach contents were examined from 748 largemouth bass, Micropterus salmoides (<125 mm total length), collected from DeGray Reservoir during April-November 1976. Fish constituted 59% by weight of the total diet and occurred in 81% of the stomachs; crayfish made up nearly 38% of the weight and occurred in 24% of the stomachs. Sunfish, the principal fish food (about 28% by weight), were observed in 36% of the stomachs. Shad were the second most important prey (23% by weight and 29% frequency in occurrence). Crayfish constituted about 42% of the total weight of the food of bass 200 mm long or longer, but only 12% in bass less than 200 mm. Crayfish consumption was greatest during the fall.
