The weight of the fish ranged from 1.850 to 3.450 kg. Length meas-urements were taken for 72 fishes which ranged from 58 to 74 cm. About 70% of gut content con-sisted of cephalopods. Unidentified digested mat-ter and mud constituted the remaining 30%. Pristipomoides filamentosus Male : Female ratio was 1:0.6. Out of 27 females examined 20 were in resting stage and the re-maining in developing condition. The entire fish catch was sold by auction at the landing centre for Rs.3,00,000/- at a rate of Rs .30 / - per kg.
