Abstract:
The present experiment was carried out to verify the “Effect of Certain Combination of Millets on several water quality parameters for Nile tilapia, Oreochromis niloticus (Linnaeus, 1758) Fingerlings”. The experiment was conducted for 60 days in the wet laboratory of Department of Aquaculture, COF, MPUAT, Udaipur (Rajasthan). A total number of 200 Oreochromis niloticus healthy fingerlings were used for the experiment, 20 FRP tanks of 225 litres capacity were used. Ten fishes were randomly distributed in five treatments (including control) with each of four replicates. The fingerlings were fed @ 4% body weight twice a day morning and evening for 60 days. For experiment, diets with pearl and sorghum millets in ratio of 1:1 at 5%, 10%, 15% and 20% in T0, T1, T2, T3 and T4 were used. The ratio was divided equally between the two feeding. The measurements for the study of water quality parameters as Air and water temperature (26.8 to 29.1 °C and 25 to 29.9 °C), pH (6.2 to 8.5), DO (6 to 8.4 mg/l), EC (150-180 µS/cm), Total alkalinity (87 to 153 mg/l), and Total hardness (380 to 620 mg/l) were monitored at fortnight period of interval. On the basis of these results, it can be concluded that sorghum millet & pearl millet in 1:1 ratio is safe for water quality and favourable for the growth of Nile tilapia (Oreochromis niloticus) fingerlings.
