Effect of an azo dye methyl red on lipid profiles in muscle tissue of freshwater fish oreochromis mossambicus

The present study was determine the effect of preferably used textile dye, methyl red on fingerlings of Oreochromis mossambicus as much report is unavailable on juvenile toxicity. Muscle tissue of fish were analysed for the effects of the azo dye methyl red, since it is a major target tissue for nutrient storage and is the main edible part of the fish. They affect the biologically active molecules like lipids. The fishes were maintained for a period of 40 days at two sublethal concentrations of the dye. The present study revealed a decline in total lipids, cholesterol, phospholipids, triglycerides and free fatty acid (FFA).
