Abstract:
The present study was carried out to evaluate the effect of Supplementation of Zinc Nanoparticles on Growth, Feed Utilisation and Survival on Nile Tilapia (Oreochromis niloticus) fry. The experiment was carried out for 60 days. The growth parameters were measured at fortnightly (15 days). Total four experimental diets were formulated with 40% protein. One was control diet and in other three zinc nanoparticle was incorporated in different concentration of 10 mg/kg, 20 mg/kg and 30 mg/kg. The result of the present study showed that up to 20 mg/kg (T2 treatment) the growth of tilapia fry has shown to increase. Whereas in T3 treatment (30 mg/kg) it has not shown increase in comparison to T2 treatment (20 mg/kg). Survival did not show any significant difference among the treatments. In the case of carcass composition, incorporation of zinc nanoparticle did not show any significant difference within treatment. Hence, it can be inferred that providing a supplement up to 20 mg/kg can have a beneficial impact on the growth of Nile tilapia (Oreochromis niloticus) fry.
