However total landings of male (48976 kg), female (38745 kg) and berried (16533 kg) crabs were recorded maximum in Mallipattinam. However male (23932 kg), female (16087) and berried (5418) crabs were minimum in Pasipattinam. Among 12 crab species reported P. pelagicus (165297.8 kg) was maximum and C.truncata (18371.28 kg) was minimum for all sexes.
