Abstract
The food habits of the mud crab, Scylla serrata from Karwar waters were studied. A total of 151crabs over a range of 41.04-136.82 mm (carapace width) representing ten size groups were examined. The
principal dietary constituents, based on occurrence were crustaceans, detritus, molluscs, fish and miscellaneous
items. Based on volumetric measurements - detritus, fish and crustaceans were the major
trophic components comprising 35.70%, 23.57% and 18.37% of the total food volume respectively.
Detritus was the major food group in juvenile crabs (<70mm) while in sub-adults (81-110 mm) and
adult (< 110 mm) specimens it was the remains of crustaceans and fish.
