A total of 187 samples of Channa punctatus (Bloch, 1793) from River Gomti of Lucknow region, Uttar Pradesh were studied during 2011. The sex ratio of 1: 0.84 was not significantly different from 1:1. Monthly variation in the gonadosomatic index (GSI) and maximum number of stage IV gonads encountered in the months of May to August indicated that the spawning season extends for about 4 months and spawning was high during the monsoon season. Absolute fecundity varied from 11000 to 28000, with an average value of 14920. Fecundity was found to be highly correlated to the total length (r = 0.9201), body weight (r = 0.9133) and weight of ovary (r = 0.8536) with all correlation coefficients being highly significant (p<0.0001). Total length (TL) of fish and weight of the ovary also highly correlated (r = 0.9551, p<0.0001). This study provides primary information on reproductive parameters of C. punctatus from River Gomti which can be utilised for management of the resource.
