Hematology and serum biochemical changes in response to change in saline concentration in fresh water fish Notopterus notopterus

The present investigation aim was to study the hematological and serum biochemical changes under increased saline medium in the fresh water fish Notopterus notopterus. The fish was able to thrive well in higher well in higher saline medium up to 0.16%. The exposure to saline medium was for a period of one month. After the termination of exposure to saline medium, the fish blood was collected and proceeded for hematological and serum biochemical studies. The result indicates that there was no change in the blood glucose, urea, where as there was an increase in the blood protein, triglycerides and cholesterol along with hemoglobin, RBC, WBC, creatinine, enzymes like SGPT, SGOT, alkalinephosphatase. The blood electrolytes like sodium, potassium and calcium also increased in experimental fishes.
