Abstract

Digestive tract contents from 486 smalleye shiner Notropis buccula and 475 sharpnose shiner N. oxyrhynchus collected from the upper Brazos River, Texas, during January through December 1998 were examined. Both species are generalist feeders, with terrestrial and aquatic invertebrates representing 38 and 71%, respectively, by weight, of the diet. Detritus, plant materials and sand-silt represented 15, 5 and 42%, respectively, of the smalleye shiner diet and 4, 7 and 18%, respectively, of the sharpnose shiner diet.
