The present paper deals in the maturity stages, ova diameter and spawning season, of Otolithus argenteus from Karwar waters. The seven stages of maturity were determined based on the macroscopic appearance and microscopic study of intra ovarian eggs. The average size at first maturity was found to be 160 mm. The diameter of ova varies from 0.01 to 0.82 mm. with various modes, indicating the nature and the frequency of spawning.
