Abstract: (68 Views) |
| Fishing activity causes stress and physiological changes in the immune system. The aim of this study was to investigate the hematological, immune, and antioxidant capacity indices of male and female Caspian roach (Rutilus lacustris) in marine and pond conditions under fishing conditions. Hematological factors, except for the number of white blood cells, neutrophils and lymphocytes, differed between groups in the fishing conditions. Fishing stress in both sexes of sea roach caused a significant increase in the concentration of cortisol and glucose hormones. There was no statistical difference in the antioxidant enzyme of superoxide dismutase between the sea-caught and pond-caught groups of Caspian roach, while there was a significant difference in the catalase and malondialdehyde enzymes. Overall, the results showed that although fishing is considered as a stressor for aquatic animals, it wasn’t the main cause of changes in blood, immune, and antioxidant factors in the Caspian roach. |
