An experiment was conducted to evaluate the growth performance of carps, the overall production and the economics in carp-mola polyculture system in some seasonal farmer's ponds in Purusottampur block of Ganjam district, Odisha over a period of 7 months during August, 2018- February, 2019. The experimental design was comprised of Control (T0) where only Carps fingerlings (Catla, Rohu, Common carp; 4:3:3) @ 10000/ha were released. Other treatments were T1 (T0 + mola@ 7500/ha), T2 (T0 + mola@ 10000/ha) and T3 (T0 + mola@ 12500/ha). The ABW gain and SGR of all Carps were found to be in decreasing trend fromT0 to T3 (T0>T1>T2>T3) where as the overall production in T0, T1, T2, T3 are found to be 3407kg/ha, 3309kg/ha (3211+90), 3271kg/ha (3183.9+87.31) and 3270kg/ha (3184.27+85.73) respectively. The B: C ratio was found to be greater in control than in other treatments with values as 2.56, 2.42, 2.34 and 2.30 respectively. However the overall production of carp- mola and B: C ratio were not significantly higher in controls than in treatments and the farmers got nutritionally rich mola for consumption during the crop and carps as cash crops at season end.
