Breeding biology study in C. striatus of Badin district described from 80 matured fishes. It was observed that the egg size was found to be increased during July to October (0.70 to 1.30 mm). This resulted the spawning period of C. striatus starts from July to October with peak in September. The gonadosomatic index (GSI) values indicated single peak (2.10 and 8.0) during September for both the sexes respectively. Fecundity estimation of C. striatus 12 matured specimens was randomly selected. The estimation of fecundity was ranging from 3000- 12000 eggs in a fish of 33.4to 50.8 cm (TL) and 460.5 to 1100.0 g weight. It was noted in the present study that one g of ovary contains 335eggs and one g of body contains 115 eggs. The values of coefficient of correlation (r) in different parts of the body such as fecundity versus body weight, total length and gonad weight in C. striatus found to be closely related with total length than the rest of body parameters.
