Abstract
The present study deals with the food and feeding habits of catfish Sperata aor collected from Bhadra reservoir of Karnataka, India. Food of the fish consisted chiefly of weed fishes followed by insects, prawns and molluscs. Juveniles of carps were rarely recorded in the gut and probably the fish is not inimical to carp fishing. Higher feeding activity in S. aor was observed during June to August. Fishes with empty stomachs were found in all months. The stomachs of fishes collected for the study of food and feeding habits were classified depending on their relative fullness into gorged, full, 3/4 full, 1/2 full, ¼ full, little and empty. Fishes with stomachs classified as gorged, full, 3/4 full, 1/2 full were considered to have actively fed, whereas those with ¼ full and little as poorly fed.
