The project was carried out to study the effect of inorganic fertilizer (Urea) on the growth performance of major carps. Fertilization of treated pond was done by urea at the rate of 0.20 g N/100 gm of fish body weight. In the control pond the average weight gain of 179.5, 174.5 and 201.4 g were recorded Labeo rohita. Catla catla and Cirrhinus mrigala respectively. In treated pond the average weight gain of 277.3, 211.6 and 322.1 g for Labeo rohita, Catla catla and Cirrhinus mrigala respectively. Net fish yield (all three species together) in control and treated ponds were 18.455 and 27.103 Kg/pond/year respectively. Treated pond showed 1.46 times greater net fish production as compared to that of control pond.
