Abstract: An attempt has been made to provide some vital aspects on spawning frequency and fecundity of Cobia based on the samples collected from fishery exploratory surveys and from the landing centers at Mumbai. Frequency of spawning was determined based on the modes of ova diameters in the mature ovaries. The Ova Diameter study indicated that Cobia follows a protracted spawning season with the individual spawning more than once in a season. Absolute fecundity estimated ranged from 1,231,630 to 1,800,350 numbers. Fecundity index obtained was from 2,123 to 2,372 eggs per gram ovary weight. The results obtained in the present study were compared with similar studies round the world and discussed.
