It was observed that both males and females mature simultaneously. The gonads attain the maximum weight 5.05±0.88 and 12.5±1.55 for males and females respectively in July and minimum in November. The fish has only one spawning season of short duration, running from June to August as indicated by the peaks of gonadosomatic index and ova diameter. The fecundity of C. reba varied from 20,722 eggs in fish of 150 mm (TL) to 211,200 in fish of 290 mm total length. The fecundity increased with increasing total length, gonad length, gonad weight and body weight. The relationship of fecundity was curvilinear with total length and gonad length and linear with body weight and gonad weight.Read More
