STUDIES ON THE IMPACT OF THE PARAVANAR RIVER POLLUTANTS ON GLUCOSE AND GLYCOGEN LEVEL OF FRESHWATER PRAWN, MACROBRACHIUM MALCOLMSONII (H.

In the present study, to find out the impact of Paravanar river pollutants on freshwater prawn, Macrobrachium malcolmsonii collected from three Stations viz., Station-I, Station-II and Station-III such as, Unpolluted (StationI), Less polluted (Station-II) and More polluted (Station-III) regions. Biochemical changes such as glucose and glycogen contents were analyzed in various organs like, gills, testis, vasdeferens, hepatopancreas, and androgenic gland. A decline in glycogen content and an increase in glucose content in all the tissues of freshwater prawn, Macrobrachium malcolmsonii collected from three stations were secured. There was a significant difference (p<0.01) in the quantitative biochemical parameters such as glucose and glycogen content. The results obtained are discussed in details.
