ABSTRACT

The present study aimed at the effect of different quantity of selenium nanoparticles incorporated feed on growth and biochemical characteristics of common carp Cyprinus carpio. Selenium nanoparticles were synthesized and characterized by using UV-Vis, SEM, EDAX and FTIR. Different quantity of selenium nanoparticles such as 10, 20, 30, 40, 50 mg/100 g was prepared by using Fish meal, Groundnut oil cake, Wheat flour and Tapioca flour. Feed utilization parameters and biochemical characteristics in muscle, gill and liver of Cyprinus carpio were estimated after 21 days. Absorption spectra of the synthesized nanoparticles were studied using a UV-Vis spectrophotometer and the maximum peak was observed between 240 to 320 nm. SEM image shows that the selenium nanoparticles are spherical and in the micro-scale of 0.37 mm. EDAX spectrum recorded on the selenium nanoparticles shown three peaks located between 0.9 KeV, 1.3 KeV and 2.5 KeV. The FTIR spectrum of selenium nanoparticles was analyzed in the range of 500-5000^¯¹ and spectral bands and functional groups are Alcohols, Ketones, Alkynes, Alkyl, Halides and Amines. The final condition factor increased in all the feeds. The survival rate of Common carp is 100% in feed III and IV. Feed consumption and Feed conversion efficiency of common carp was higher in Feed V. Feed conversion ratio was good in Feed VI. The growth and specific growth rate were higher in Feed VI. Assimilation and metabolism were higher in Feed III and VI. Gross growth efficiency and net growth efficiency was higher in Feed VI and IV. Total protein, carbohydrate and lipid in muscle, gill and liver of Common carp were higher in Feed VI
