The holy river Ganga is known to harbour more than 250 species of fish including Gangetic major carps, large cat fishes, a large number of cyprinoids and many others. In the present investigation serum Thyroid Stimulating Hormone (TSH) level and muscles biochemical profile were assessed in four major fish species of Ganga near Patna (India) namely Catla, Labeo, Hilsa and Mystus during pre monsoon period and post monsoon period. The present study revealed a significant variation in the concentration of total protein, carbohydrate and lipid content in these four fish species. During pre monsoon period out of these four fish species Catla showed maximum total protein level (7.54±0.134 g/dl) where as Hilsa encountered the least (6.67±0.138 g/dl). Glucose content was recorded maximum in Mystus (95.12±1.791 mg/dl) and minimum in Labeo (66.2±0.163 mg/dl). Triglyceride content showed highest range in Hilsa (232.6±2.965 mg/dl) while minimum was recorded in Labeo (112±1.825 mg/dl). The cholesterol content was maximum in Mystus (256±2.624 mg/dl) while minimum in Labeo (178.0±2.624 gm/dl). Serum TSH level varied from 0.06±0.012 mIU/ml in Labeo to 2.1±0.032 mIU/ml in Mystus species. However, during post monsoon period serum TSH level varied from 1.743±0.314 mIU/ml in Hilsa to 11.98±1.759 mIU/ml in Mystus species. By altering the biochemical pathway through neuroendocrine control, the elevated serum TSH affects the protein synthesis and ultimately lowers the nutritional value of fish. The present study elucidates the quantitative variation of total protein, carbohydrate and lipid contents from muscles of few Gangetic fishes. The prevailing physicochemical status synchronizes the variation in biochemical and endocrinal profile of these fishes. [ABSTRACT FROM AUTHOR] |
