dc.description.abstractStudies on the seasonal occurrence of maturity stages of Sepiella inermis revealed that this species is a prolonged breeder as mature and spent specimens were recorded almost round the year. Two peak spawning periods, one in November and another in March were observed. Mature animals were represented by a wider length range ruling out the possibility of semelparity. The gonodosomatic and nidamental gland indices increased during maturation. The females attained maturity earlier than males. Fecundity showed a significant correlation with dorsal mantle length. Cuttlefishes contribute substantially to the cephalopod fishery of Thoothukkudi (8'47' N,, 78"9' E), located in south east coast of India. Out of the three species of cuttlefishes, viz. Sepia pharaonis, Sepia aculeata and Sepiella inurmis, which form commercial fishery in this coast, S.inerrnis is notable for its year round occurrence.en_US
