Comparative studies on blood electrolytes of the fresh water fish, Notopterus notopterus from three aquatic bodies

The present study is undertaken to determine baseline levels of blood electrolytes for the fish, N.notopterus collected from three different aquatic bodies situated at different locations around Gulbarga region. The electrolytes such as sodium and potassium levels are having some difference in the fish collected from the three aquatic bodies. The data for blood Sodium 88.49 ± 16.68 mmol/l. in the fish from Bheema River, 101.32 ± 4.17 mmol/l. in the fish from Kagina River, and 87.5 ± 3.41, mmol/l. in the fish from Saradgi Stream., Potassium 14.48 ± 1.14 mmol/l. in the fish from Bheema River, 14.63 ± 1.15 mmol/l. in the fish from Kagina River, 13.19 ± 0.70 mmol/l. in the fish from Saradgi Stream. The blood calcium data are 9.00 ± 0.30 mg/dl. in the fish from Bheema River, 8.69 ± 0.50 mg/dl. in the fish from Kagina River, and 8.39 ± 0.45 mg/dl. in the fish from Saradgi Stream. Based on the results obtained for blood electrolytes, the fish N.notopterus from three aquatic bodies are although healthy and thriving well, the Bheema River provides better environmental conditions.
