Studies on the maturity and spawning of silver pomfret, Pampus argenteus (Euphr.) in the Arabian Sea

Abstract

Maturity and spawning of the Silver Pomfret, Pampus argenteus (Euphr.) have been studied in an area between the Gulf of Kutch and the Gulf of Cambay. The method of studying were: direct observation on the occurrence of maturity stages, measurements of the diameter frequency of ocytes, seasonal variation in the condition factor and the gonadosomatic index. The results have indicated that the species has a prolonged spawning season-commencing from February and lasting till August. This has been verified by the seasonal abundance of post-larvae and juveniles. A general tendency amongst the fish to migrate from the northern waters of Gujarat towards the Gulf of Cambay has also been noticed
