Abstract:
The current study was conducted to determine the “Effect of sorghum millet (jowar) supplementary Diet on Growth and survival of Oreochromis niloticus (Nile tilapia) (Linnaeus, 1758) Fingerlings” The experiment was conducted for 60 days. In this study 20 plastic tanks of 225 liters were used for 5 treatments with each of four replication. Fisheries respectively were homogeneously distributed in each tank at the ratio of 10 fishes per tank. Four experimental diets without sorghum millet(SM) at the ratio of 5%, 10%, 15%, and 20% in T₀, T₁, T₂, T₃ & T₄. The important water quality parameters including air temperature, water temperature, pH, dissolved oxygen, electrical conductivity, total hardness, total alkalinity were analyzed and average air temperature (26.175 °C), water temperature (25.8 to26. 9 °C), pH (7.2 and 7.6), dissolved oxygen (6.1 and 6.750mg/l), electrical conductivity (146 and 162 ms/cm-1), total hardness (613 and 634.35 mg/l), total alkalinity (124 and 149mg/l) were noted in all treatments respectively during experimental period. The result shows that all water quality parameters in all treatments were existed within the permissible for aquaculture. On the basis of these result, it also concluded that aquatic environment was favorable for the fish survival and fish growth.
