Cuttlefishes were exploited exclusively by trawls along the coast. Growth, recruitment,mortality and exploitation rates of Sepia aculeata and Sepia pharaonis were studied.Fishery of the former was supported mainly by zero year and the latter by zero and one +age groups. Both attain sexual maturity during the first year itself and spawn duringAugust-March with peak during November-December. Natural mortality of S.aculeatawas 2.22, fishing mortality 2.34 and total mortality 4.56. It was 1.69, 1.97 and 3.66respectively for S.pharaonis. Exploitation rate was 0.52 and Emax 0.72 for S.aculeata and itwas 0.54 and 0.76 respectively for S.pharaonis. Their mortality and exploitation ratesindicated that stock remains under-exploited and have considerable scope for improvingthe production. However, both stock and catch exhibited wide annual fluctuation withdeclining trend during the period. These necessitated immediate attention includingmeasures to minimise juvenile exploitation for improving stock and fishery.
