Abstract: The gonadal development of Barbus capito was studied by light-micro-scope feeded in northern Jiangsu, and the characters of the ovary and the testis at different stages were described. The gonadal developments of the fish were divided into 6 stages. The gonads started to divide from 6 months old. It’s consistent in development time of the ovary and the testis, the earliest time of the stageⅠ all appeared in the 9 months, the stage Ⅱ appeared in the 12-18 months, the stage Ⅲ appeared in the 22-24 months, the stage Ⅳ appeared in the 28 months, from now on, the male fish growed faster than the female fish, the male at maturity in the 32 months, the weight was(686.49±25.38)g, the gonado-somatic index(GSI)was 10.69%, the female at maturity in the 34 months, the weight was(1 349.63±29.56)g, the GSI was 10.36%. The ovaries development in Barbus capito is synchronous.
