Biochemical effects of commercial feedstuffs on the fry of climbing perch (Anabas testudineus) and its impact on Swiss albino mice as an animal model

This study assesses the biochemical effects of commercially available fish feedstuffs on the fry of climbing perch (Anabas testudineus). Subsequently, its impact on experimental animal, Swiss albino mice, is also examined. In order to access the impact of commercial fish feed and feed consumption fish on the experimental animal, the proximate, biochemical and histopathological analyses were done using standard methods. The proximate composition as well as the concentrations of Pb, Ni, Mn, As, Zn, and Cd in the fish feed, different parts of the A. testudineus fish and different parts of the A. testudineus fish-treated experimental mice liver, were all determined using Energy Dispersive X-ray Fluorescence (EDXRF) Spectrometry. The highest levels of Cr, Pb and As were observed in the liver of Swiss albino mice treated with FFT2 and FFBB2 and their concentrations were 0.156, 0.491, 0.172 μg/g and 0.166, 0.771, 0.157 μg/g respectively. No significant changes of protein, fat, crude fiber, moisture and ash contents were observed after proximate composition analysis of fish feeds, A. testudineus and A. testudineus treated experimental mice.Significant amounts of heavy metals (Cr, Mn, Zn Cu, Ni) were found in fish feed, different parts of A. testudineus fish and in the experimental mice. However, remarkably high amounts were observed in the A. testudineus fish’s head and bone with body parts. Biochemical analysis of blood samples of A. testudineus fish treated experimental mic...
