Abstract
An attempt was made in the present article to review the food and feeding habits of the
fishes of the family Sciaenidae from Indian waters. Members of the Sciaenidae family are
commonly referred to as croakers or drums because of the sound produced by their swim
bladders. Sciaenids are distributed in tropical and sub-tropical oceans. They are carnivorous,
feeding mainly on crustaceans, small fish, molluscs, annelids and polychaetes and exhibit
cannibalism. Sciaenids display differences in food preferences between early stages and
adults; the former prefers zooplankton and crustaceans, and the latter mainly smaller
teleosts. The feeding intensity was found to be higher in smaller groups compared to mature
fish. Considerable temporal variations were recorded in food item occurrence, indicating
an empty stomach during peak breeding and a wide spectrum of food items during other
seasons.
