Keshava, and Joseph, P Santha and Mohan Joseph, M (1988) Feeding habits of the Pearl-Spot Etroplus suratensis (Bloch) in the Nethravati - Gurpur estuary. The First Indian Fisheries Forum. Proceedings. pp. 203-206.
Occurrence of decayed organic matter in the stomach showed seasonal variations which were related to relative abundance of food, selectivity, age and diurnal variations in feeding. Filamentous algae Spirogyra fonned an important item of the diet in November. A change in diet with increase in size of fish was noticed. While fish of 8 em T L preferred decayed organic matter and microvegetation, larger fish fed on a variety of food. Increased occurrence of sand grains in larger fish suggests habitual bottom feeding. Intensive feeding was noticed in early mature and spent fish. Feeding intensity appears to be related to spawning activity, besides food abundance.
