Ameliorative effect of Nelumbo nucifera seeds and wheat grass formulated feed against tannery effluent toxicity and stress in freshwater fish Oreochromis mossambicus

Abstract

Amelioration of tannery effluent toxicity and stress revival was analysed through an approach by preparing a formulated feed with feed components comprising Nelumbo nucifera seeds and Wheatgrass as major ingredients in an enhanced formulation. The formulated feed was fed to fingerlings of Oreochromis mossambicus exposed to tannery effluent in laboratory confinement to observe its effect on growth and protective effect from toxic nature of the effluent. This study aimed to assess the effect of the sublethal concentration of tannery effluent over an exposure period of 45 days. The LC50was analysed for the tannery effluent to select the suitable sublethal concentration. The body weight differences was be determined, the muscle tissue was analysed for biomolecular constituents by Fourier Transform Infrared spectroscopy (FT-IR) analysis. Alterations were observed in body weight and muscle tissue biochemical constituents in fishes exposed to the effluent fed on normal diet and formulated feed.
