Assessment of Biomarkers of Oxidative Stress and Antioxidant in Wild and Farmed Çoruh trout (Salmo coruhensis) Spermatozoa

OpenAlex English

Behaviour and physiology in fish are affected from environmental factors. Particularly, habitat and culture environment in aquatic animals are essential for life stages. In this study, biomarkers of oxidative stress and antioxidant were compared in wild and farmed Çoruh trout (Salmo coruhensis) spermatozoa. In spermatozoa of Çoruh trout, lipid peroxidation (malondialdehyde), glutathione and enzymatic antioxidant activities (catalase, superoxide dismutase, glutathione peroxidase) were assessed. Our data demonstrated that superoxide dismutase (0.44±1.25 Umg-1 protein), catalase (15.21±4.69 k.g-1 protein), glutathione peroxidase (42.89±0.61 Ug-1 protein), glutathione (0.18±4.01 µmolg-1 cell) and malondialdehyde (2.49±0.12 nmol.g-1 cell) levels in wild fish were low compared to spermatozoa of farmed fish. Overall, alterations in malondialdehyde levels and the antioxidant status could be differences in habitat.
