“…Exposure to 28 µg l −1 chlorpyrifos significantly reduced protein content in the skeletal muscle of diploid Clarias gariepinus compared to the control group. Consistent with the present study, a decrease in protein content was ob served in different tissues of C. batrachus following exposure to sublethal chlorpyrifos concentrations for 28 d (Narra et al 2011). Possible explanations for the reduced protein content are the destruction or necrosis of cells, resulting in protein synthesis im pair ment (Bradbury et al 1987), and the enhanced proteolytic activity in the muscle under pesticide exposure.…”

“…Similarly, a reduction in free AA levels was observed in the muscle of C. batrachus after 28 d of exposure to 825 and 1650 µg l −1 chlorpyrifos (Narra et al 2011). Fewer changes in AA levels in chlorpyrifos-exposed triploids may indicate the 108 Fig.…”

“…For example, changes in FA compositions were employed to evaluate stress responses to trace elements and polycyclic aromatic hydrocarbons in Mediterranean mussels My ti lus gallo provincialis (Signa et al 2015). In another study, a 28 d exposure to sublethal chlorpyrifos concentrations decreased total protein, free AA, and ammonia contents in the gill, kidney, liver, and muscle of walking catfish Clarias batrachus (Narra et al 2011).…”

There is a paucity of information about the influence of ploidy status on physiological parameters in organisms following contaminant stress. Also, little is known about the changes in nutritional values of fishes in response to the exposure to contaminants. Full-sibling juvenile Clarias gariepinus were exposed to 3 levels (mean measured 8.9, 17.5, or 28.0 µg l −1 ) of chlorpyrifos for 21 d. The levels of 3 fatty acids (FAs) in the muscle were significantly different between unexposed diploid and triploid fish. In the chlorpyrifos-exposed fish, the levels of most amino acids (AAs), some FAs, protein, and moisture content were affected in the muscle of diploids, while the levels of some FAs and ash content were changed in the muscle of triploid fish. This work represents the first study of changes in FAs and proximate composition in triploid animals in response to environmental stressors. Fewer changes of nutritional values in triploid C. gariepinus under chlorpyrifos exposure may indicate higher adaptability of triploids than diploids towards environmental stressors. Significant changes in the muscle protein content and AA and FA compositions in diploid Clarias gariepinus in response to chlorpyrifos exposure suggest their application as sensitive indicators of aquatic environmental pollution.

“…Among vertebrates, fish is often used as suitable bio-indicator, because of their wide distribution in aquatic environment, long lifespan, free swimming, ability to respond against environmental xenobiotics, and importance as a food source for human beings (Gupta et al, 2009;Narra et al, 2011;Correia et al, 2017).…”
