Abstract

The food habits of seven commonly caught demersal fishes from the Cochin region,
namely, Platycepha'us maculipinna, Pseudosciaena sina, Otolithus argenteus, Lactarius
lactarius, Saurida tiimbil, Trichiurus tepturus and Nemipterus faponicus have been
studied during the period from February 1965 to October 1967.
It is seer, that these fishes could be grouped into three categories on the basis of
their food preferences. One group consisting of L. lactarius, T. lepturus and
S.tumbilh largely piscivorous. The second category feeds on a variety of crustaceans
and also fish. This includes P. maculipinna, P. sina and O. argenteus. The third
category represented by the thread-fin bream A'. Japonicus consumes small crustaceans
dominated by amphipods. Polychaetes and echiuroids form a significant proportion
of the food of these fishes.
