The study deal with the comparative growth performance of Pangasius sp. cultured at different stocking density in floating net cages in Mahi Bajaj Sagar dam of Banswara (Rajasthan). The experiment was conducted in 05 replications at 03 stocking densities in 15 floating net cages of the size-3.65 x 3.65 x 5.48 m(L x W x D). The stocking densities were- T1 (2600 fish fingerling/cage), T2 (2800 fish/cage) and T3 (3000 fish/cage). During experiment of 60 days, the fingerlings of pangas (Pangasius hypophthalmus) were fed on commercial floating pelleted feed given to fish @ 5% of their body weight per day. The fishes were properly maintained for good health by regular feeding schedule and use of prophylactic measures and probiotics. The results indicated that the weight gain (NWG), specific growth rate (SGR), food conversion ratio (FCR) and gross conversion efficiency (GCE) were significantly different (P<0.05) in all the treatments. Still, the significantly higher growth performance was observed in T1. In this treatment NWG, SGR and GCE were the highest 289.570c±0.928g, 1.698c±0.019 and 0.852c±0.002 respectively. The lowest FCR (1.174a±0.004) was also recorded in T1 compared to all other treatments. The net yield in 60 days was maximum in T3 (9.080/m3) and per cent increase in biomass was maximum (176.955%) in T1. The fish growth was maximum at 30-45 days of observation which corresponds with water temperature of 23.68±2.07°C, pH-8.54±0.13 and dissolved oxygen 8.26±0.10 mg/l. The higher Ponderal index was noticed in T1 i.e. 2.403b±0.057 indicating wellness of fish. Through this study we can recommended that in above conditions 2600 fingerlings of Pangasius hypophthalmus stocked in each floating net cage gives maximum growth and per cent increase in fish yield.
