Abstract :

The present paper deals with some biological aspects of Coilia dussumieri (Valenciennes, 1848) from the offshore waters along Mumbai Coast (Maharashtra). Four stages of maturity viz. immature, maturing, mature & ripe ova were recognized during the maturation studies of fish. Ova diameter study revealed that fish spawns once in the spawning season which, is evident from appearance of single peak in the mature stock of ova separated from a small peak of immature stock of ova. The comparison of exponential values of fecundity–fish length (L), fecundity–fish weight (W), fecundity–fish ovary weight (OW) & fecundity–fish ovary length (OL) showed that the production of ova to be more depended on weight of gonad than length & weight of fish and fecundity of fish was more closely related to the weight of fish ovary than the length & weight of the fish. These findings are in concurrence with other researchers regarding observations of linear relationship between fecundity and weight of fish.
