Abstract EN
The feeding dynamics of Stolephorus commersonnii along the coastal waters of South Andaman during October, 2011, to September, 2012, were examined by employing “point’s method.” The results of the present study has shown that S.
commersonnii mainly is a planktonivorous carnivore chiefly feeding in the pelagic realm on planktonic crustaceans, bivalves, gastropods, and miscellaneous food items.
The copepods formed the main prey item, contributing their maximum during November 2011 (47.55%) and lowest in December (24.21%) which was confirmed by various food preference indices.
There was no significant seasonal variation in the feeding preference.
Lower length classes fed mainly on planktonic copepods and amphipods whereas the higher length classes fed mainly on postlarval shrimps and planktonic crustaceans like Lucifer sp.
and Acetes sp.
Feeding intensity was seasonal, but independent of the length of fish.
Gastrosomatic index was highest during monsoon, indicating active feeding.
During the period when a maximum percentage of fully mature individuals were present, the feeding intensity was found to be low.
The trophic level of this species was found to be 2.96±0.11.
