Abstract

The food and feeding habits of three deep sea sharks Halaelwus hispidus, Eridacnis
radcliffei and lago omanensls were studied based on the specimens obtained from
trawl catches off Mandapam, Gulf of Mannar at a depth ranging from 150. to 200 fathom.
The percentage of volume and occurrence of each item of food was found separately
to determine the importance and abundance of the various food items in the
diet of these sharks. They were found to be carnivorous; feeding chiefly on fishes,
crustaceans and squids. .Squids were conspicuously absent in the food of juveniles. An
interesting phenomenon of segregation by sex was noticed in H. hispidus and E. radcliffei
with the males dominating in the catches.
