Comparative studies on lipid in freshwater and treated sewage water culture fish labeo rohita

Biochemical characteristics (lipid in muscle, intestine and gill) of the freshwater carp fish Labeo rohita were estimated. Maximum lipid content was recorded in muscle tissue of Labeo rohita at treated sewage fish culture pond (station – II) and minimum protein content was observed in gill tissue of Labeo rohita at freshwater fish culture pond (station – I). Total lipid content was studied in different days of 5, 10 and 15 days. The different tissues of muscle, intestine and gill lipid maximum was found to be sewage treated fish and compared than fresh water fish Labeo rohita. This study recommended that the wastewater should be treated before discharge into this culture pond.
