Significant differences were noted immediately following the conclusion of immersion: mean corpuscular volume (MCV; elevated values in the NaCl+CuSO4 group) and mean corpuscular hemoglobin concentration (MCHC; elevated values in the NaCl group). Immediately following fish exposure in all three experimental groups (0 h), significantly elevated glucose and lactic acid levels were recorded as were lowered levels of chloride ions (Cl-).
