COMPARATIVE STUDIES ON LIPID OF FRESH WATER AND TREATED SEWAGE WATER PONDS CULTURE CARP FISH LABEO ROHITA IN TIRUCHIRAPPALLI DISTRICT

The biochemical characteristics (lipid in muscle, intestine and gills) of the freshwater carp fish Labeo rohita were estimated. The lipid content maximum was recorded in muscle tissue of L. rohita at treated sewage fish culture pond (station – II) and minimum, the protein content was observed in gill tissue of L. rohita at fresh water fish culture pond (station – I). The total lipid content was studied in different days of 7, 14, 12 and 28 days. The different tissues of muscle, intestine and gill lipid maximum was found to be sewage treated fish and compared than fresh water fish L. rohita. This study recommended that the wastewater should be treated before discharge into this culture pond
