Assessment of fecundity and gonadosomatic index of Clarias batrachus.

Fecundity, Clarias batrachus, GSI, Marathwada region.

Present study deals with the assessment of fecundity and gonadosomatic index of Clarias batrachus collected from Marathwada region, during January,2013 to December,2013. The mean value of fecundity was estimated 14574�2002 eggs with a mean total length of 25.6�1.35 cm and mean total body weight of 156�13.03 g. The relationship of fecundity with other parameters such as total length (TL), total weight (TW), ovary length (OL) and ovary weight (OW) were found to be linear and the values of correlation coefficient (r) was 0.28, 0.25, 0.69 and 0.98 respectively. The average relative fecundity was calculated as 94.1�13.24. Highest value of GSI was recorded in the month of August.
