Effect of Different Concentrations of Zinc Oxide Nanoparticles on Growth and Hematology of Catla Catla
Alfa Sherin | Nimisha P 
Abstract: Zinc is essential for aquatic biota including fishes at lower concentration, but when it reaches higher concentrations it becomes toxic. The objectives of the present work were related to the impact of different quantities of zinc oxide nanoparticles on the growth and haematology of Catlacatla. Different quantities of zinc nanoparticles such as 0.3mg/l, 0.6 mg/l, 0.9 mg/l and 1.2 mg/l were prepared by using a fish meal. Feed utilization, length weight studies, survival rate and haematological parameters were estimated after 45 days of feeding. This study provides that 1.2mg/l of zinc oxide nanoparticles incorporated feed was suitable for the growth and haematological parameters of Catlacatla and it would be used in the feed of fishes as micronutrients.Freshwater is the main habitat of this fish, lakes, ponds, rivers, streams, swamps, wetland pools came under the freshwater ecosystem. Several fishes like Rohu, Catla, Shrimps, etc. are found in such habitat. In this study zinc oxide nanoparticles are given to the catla fish in different doses with their normal fish feed. The feeding to fish was carried out every day in two equal installments. The study period was 6 weeks. In each week weight of the fishes were record. After 6th week length and weight of the fishes were measured and compared.
