The objective of this study was to determine the fecundity and the type of spawning of H. littorale. Analysis of the percentage distribution of the oocyte diameter softh e females, in five different stages of gonadal development, showed that this species is a total spawner. There were two different size graups of oocytes with synchranic development. The total fecundity varied from 9, 144 to 31, 698 mature oocytes.The fecundity, when related to total length and weight, showed that it increases with the enhance in total length and weight.
