Abstract

Study on spawning biology of Sardinella dayi Regan for 1979-83 period shows that the size at first maturityis attained around 140 mm. For determining maturity and nature of spawning, condition factor (K) andgonadosomatic index (GSI) were utilized. The spawning in this species is protracted and lasts fromOctober - December, and from January - May on a reduced scale. Relation of fecundity to length andfecundity to weight when tested statistically showed better correlation in 1979 and 1980, than in the restof the years and the analysis of variance showed different rates of egg production during different years.Studies on fecundity showed that generally 66,000 eggs are released by each individual in the spawningact.
