Evaluation of different quantity of iron oxide nanoparticles on growth, haematological and biochemical characteristics of koi carp

Abstract

Background: Nanoparticles such as Se, Cu, Fe, FeO, Zn and ZnO play a vital role in aquaculture operations and are essential microminerals to enhance fish growth. The dietary supplementation of nanoparticles produces better survival, growth, antioxidant levels and immunity in aquatic organisms. The present work aimed to evaluate the different quantity of Iron oxide nanoparticles on the Growth, Haematological and Biochemical Characteristics of Koi carp. Methods: Iron oxide nanoparticles were synthesized and characterized by using SEM, EDAX, FT-IR, XRD and VSM. Different quantity of iron oxide nanoparticles such as 0, 10,20,30,40 and 50mg/100g-1 was prepared along with the fish meal, groundnut oil cake, wheat flour and tapioca flour for feed I(Control), II, III, IV, V and VI respectively. Feed utilization, hematological and biochemical composition of Koi carp Cyprinus carpio var.koi were estimated after 21 days. Result: The feed consumption, feed conversion efficiency, feed conversion ratio, Growth and Specific Growth Rate, Gross and Net Growth Efficiency of Koi carp was higher in Ex. Feed IV. The Hematological parameters of Koi carp gradually increased from Feed I to VI. Total protein, carbohydrate and lipid in muscle, gill and liver of Koi carp were higher in Feed VI and lower in feed I. The present work suggests that growth parameters are better in feed IV and hematological and biochemical parameters are higher in feed VI.
