Abstract   

    The experiment was conducted to assess the effect of inorganic fertilizer (nitrophos) on the growth performance of major carps, Labeo rohita, Calla calla and Cirrhinus mrigala. The initial average body weights of these three fish species in both control and treated ponds were 78.9, 68.2 and 102.69 and 77.9, 68.5 and 104.5 g, respectively. Fertilization of treated pond was done by nitrophos at the rate of 0.20 9 N/100 gm of fish body weight daily. The overall average weight gain of control and treated ponds were 106.60, 80.2 and 126.l g and 511.2, 490.2 and 560.5g, respectively of three fish species. Net fish yield (all the species together) in control and treated ponds were 13.937 and 69.292 Kg/pond/year, respectively. The fish production/ha/year were to be 290.307 and 1443.35 Kg in control and treated ponds, respectively. Treated pond showed 4.97 time greater net fish production as compared to that of control pond.

Key words: Labeo rohita, Catla catla, Cirrhinus mrigala, growth performance, nitrophos.
