Mystus nigriceps commonly inhabit the Tarai River that has been polluted and it may affects the reproductive biology of the fish. A study aims to understand the reproductive biology of M. nigriceps has been conducted. The fish was sampled 5 times, once/two weeks, from April to July 2019. Parameters measured were Sex Ratio, Gonad maturity Level, Gonad Somatic Index (GSI), fecundity and egg diameter. Results shown that there were 34 males and 66 females (sex ratio 1:2). Male fish was indicated by the presence of white spot in tail and it has pointed genital papilla. The genital papilla of female is blunt. The size of male ranged from 73.01-140.22 mm (SL), while that of the female ranged from 59.67-160.21 mm (SL). The GSI of male ranged from 0.12 to 13.06%, while that of the female was 0.33-15.35%. The fecundity was 4.644 to 34.938 eggs/fish and egg diameter was 0.4 to 0.7 mm. The eggs in all size distribute evenly in the ovary and it indicates that this fish is a total spawner.
