abstract
Gonado-somatic index and fecundity of the fresh water fish Xenontedon cancila was studied. The Gonadosomatic index of the ovary ranged from 0.912 to 10.870 and testis ranged from 0.186 to 1.298. Highest GSI values were recorded in the month of July in the gonads and lowest GSI value were recorded in the month of November during the study period. The fecundity of the fish was recorded low as the number of eggs ranged from 144 to 194. The diameter of ova of X.cancila was found to range from 1.20 to 1.61 mm in mature fish.
