Abstract
20 days old fry were reared for 45 days with three stocking densities having three replications to know the effect of densities on growth and survival of Nandus nandus fry in earthen pond. Experiment was designed with three stocking densities such as T₁ = 80 nos/m², T₂ =100 nos/m² and T₃=120 nos/m². Water quality criteria of experimental pond were suitable to fish culture. After 45 days rearing the ponds were harvested and percent weight gain obtained 380.38 ±50.92, 275.76 ± 40.37 and 237.50± 33.96 in T_1, T₂ and T₃ respectively. Survival rate obtained 68, 62 and 55 in T_1, T₂ and T₃ respectively. The present experiment was undertaken as lower stocking densities showed higher growth rate and survival %.
