ABSTRACT
The article describes the feeding habits of the catfish Sciades herzbergii caught in the Crabs Island (Ilha dos Caranguejos), an important coastal area of the Maranhão state, Brazil. A total of 167 individuals were collected 110 females and 57 males. All the stomach contents were identified to the closest taxonomic level. The frequency of occurrence, biomass, numerical frequency and index of relative importance (IRI) of food items were determined for both genders. Stomach repletion was predominant, demonstrating good feeding conditions for S. herzbergii. The main alimentary items in the diet of this catfish were crustaceans, fish, oligochaets and polychaets, and the decapods crustaceans were the most representative.
