Abstract

Natural diet of potentially commercial deep-water crab Charybdis smithii comprised a wide variety of invertebrates and myctophid fishes. Pelagic juveniles and subadults of this crab were found to feed actively than benthic adults. The diet of juveniles were mainly composed of pelagic shrimps (20 % by volume) and crabs (17 %). The stomach contents of subadult crabs were dominated by teleost fishes and decapod crustaceans (64 %) whereas in adults, crabs were the major food (42 %). Pronounced cannibalistic tendency was observed in this species especially among juveniles.
