abstract
The present study was observed to determine the effect of different foods on growth and survival rate of Nandus nandus spawn in cistern condition. Feeding experiments were conducted for 20 days in 12 cisterns (each cistern 2.45×1.5×0.7 m³) with three replication and four treatments T₁ (zooplankton)_, T₂ (artemia)_, T₃ (tubifex)_, and T₄ (nursery brand feed) respectively_. It was observed that the growth of Nandus nandus spawn were varied significantly (P<0.05) with different feeds. The best growth was shown by Nandus nandus spawn fed T_1. The poorest growth rate was given by Nandus nandus spawn fed with T₄ containing (protein-34.88%, lipid-15.99%, ash-17.43%, moisture-10.66%). Other two treatments T₂ and T₃ showed more or less same result. There was no significant difference in survival rates of spawn fed with live food and prepared feed. Specific growth rate and % weight gain were also best in case of T₁. Different water quality parameters were more or less same in different treatments.
