Abstract

Diet of adult specimens of Yellow Catfish Aspistor luniscutis (Valenciennes, 1840) was determined through stomach contents analysis.  The specimens were target of commercial gillnet fisheries in northern Rio de Janeiro State, southeastern Brazil.  In this region, A. luniscutis is a generalist benthophagous feeder, consuming most available prey species with crustaceans, especially penaeid shrimps, brachyuran crabs, and sciaenid fish dominating.
