Optimal stocking density of Catla catla and Labeo rohita fry in pen based nursery management system in reservoirs had been evaluated in the present study. The study was conducted in four selected sites i.e. Bendharwadi, Savarli-1, Savarli-2 and Dighad in Dimbhe reservoir, Pune District, Maharashtra. C. catla and L. rohita fry of 48-57 mm and 5.5-5.6 g were stocked in the ratio of 1:1 and reared for 55 days under four stocking densities: 11.5, 12, 12.5 and 16 fry per m2 respectively in pens installed in Savarli-2, Bendharwadi, Dighad and Savarli-1sites. During the experimental period, the fishes were fed with 36 % protein diet twice daily at the rate of 2-3% body weight. All the water quality and soil quality parameters were within the acceptable range in all the pen culture sites. At the end of experiment there was significant difference was (p<0.05) observed in growth and weight gain at different stocking densities. Highest Specific growth rate, body length gain and weight gain was recorded in Saverli- 2, while lowest were recorded in Savarli-1 pen. Highest survival percentage and number was recorded in Bendharwadi pen, whereas the lowest was recorded in Saverli-1 pen.
