Description 1848-1855
The present study had investigated different aspects of feeding biology of Grammoplites suppositus. The G. suppositus was found to feed on crabs (26.85 %), zooplanktons (14.02 %), shrimps (18.78 %), fishes (10.83 %), gastropod (5.14 %), cephalopods (3.24 %) and miscellaneous (digested matter) food items (21.2 %).  The number and occurrence of food items vary in relation to sex and size of investigated species, although the variation was insignificant (P > 0.05). However the changing environmental conditions during monsoon, pre and post-monsoon season significantly (P < 0.05) influence the feeding intensity of the observed fish. The highest percentages of empty stomach were recorded during SW monsoon and post-monsoon which may be due to increased spawning activity. The GaSI ranged between 2.48 to 7.63 whereas, HSI ranged between 1.06 to 3.98. The cannibalism was only observed during monsoon season. The females feed less actively and showed highest percentage of cannibalism than males.
