Effect of climate change on hematotoxicity/hepatoxicity oxidative stress, Oncorhynchus mykiss, under controlled conditions

tissues, namely SOD, CAT, GPx, GSH, MDA, MPO, TOS, TAS, and OSI enzymatic activity (Table 1). The changes determined for all tissue samples were found to be important at the level of p<0.05. The optimal temperature ranges (A, B, and C) groups yielded lower MDA, MPO, and TOS values within all three tissues (blood, liver, and muscle). Similarly, we determined the changes in muscle tissue during the possible stress process in order to evaluate the health status of fish. The findings showed changes in enzyme activities and increases in MDA and MPO levels due to temperature increase in all tissues. These changes were found to be statistically significant (p<0.05) (Table 1). Fig 1.
