A total of 50 mature female specimens were examined for fecundity and gonadosomatic index study. The fecundity of the fish ranged from 19343.33 to 301700 with an average value of 126812.6. The relationship between fecundity and gonad weight was most significant (r= 0.9729) than that of fecundity with other factors. The relationship between fecundity and total length, body weight and gonad weight is linear and the regression equation are i) Log<SUB>10</SUB>F= 0.0024+4.0761 Log<SUB>10</SUB>TL, ii) Log<SUB>10</SUB>F= 3.3177+1.0778 Log<SUB>10</SUB>TW and iii) Log<SUB>10</SUB>F= 3.7550+1.5161 Log<SUB>10</SUB>GW. The fish was found to spawn for several months with two spawning peaks. One in December and other in February as indicated by the peaks of gonadosomatic index.
