Present study was conducted to evaluate the growth performance of bighead carp (Aristichthys nobilis) under the polyculture system with major carps (Labeo rohita, Catla cattla and Cirrhinus mrigala) and Chinese carps (Hypophthalmicthys molitrix and Ctenopharyngodon idella). Four different treatments i.e., control (no fertilizer), organic fertilizer (T1), Inorganic fertilizer (T2) and combination of organic and inorganic fertilizer (T3) were used to determine the effect of different fertilizers on the growth of bighead carp in polyculture system. The growth of fish in treatment (T3) was found higher i.e., 1008.37 g among different treatments followed by treatment (T1) 937.98 g, which significantly differed from rest of the treatments. The control had lowest value i.e. 606.43g. Overall bighead carp showed significantly higher growth among other species under polyculture system followed by silver carp (H. molitrix) 852.85 g and grass carp (C. idella) 852.10 g. The value of thaila (C. catla) was found to be significantly higher i.e., 816.75 g amongst the major carps. The temperature range of 26 - 32 degree C was the best temperature range for the growth performance of bighead carp in polyculture.
