Abstract:

In the present investigation, the alterations in the levels of haemoglobin, total plasma proteins, glucose, and lactic acid in the blood, glycogen and lactic acid content of liver and white skeletal muscle were examined in the fresh water catfish, Heteropneutes fossilis (Bloch). After exposure to a sublethal concentration (25 g/liter) of Quinalphos for 60 and 120 days. It was found that Quinalphos produced marked changes in the chemical composition of blood, liver and muscles of Heteropneustes fossilis. In blood, all the four parameters namely, haemoglobin, total plasma protein, glucose and lactic acid decreased significantly in both treatment periods. The percentage of decrease was higher after 120 days in comparison to 60 days treatment. Haemoglobin, plasma protein, glucose and lactic acid decreased in Quinalphos-exposed catfish, Heteropneustes fossilis. The glycogen content of the liver and muscles increased but lactic acid decreased. The decrease was more marked in the case of lactic acid than in the other parameters. There was a gradual increase in liver and muscle glycogen content in both treatment periods. In contrast, the levels of liver and muscle lactic acid fell significantly, and the decrease was more marked in muscle. The present study showed that formation of glycogen and its breakdown was impaired in the liver, and aerobic oxidation of nutrients was adversely affected in Quinalphos-exposed catfish Heteropneustes fossilis (Bloch).
