Impact of Toxicants at Sublethal Concentration on Various Phospholipids during its Annual Reproductive Cycle in the Freshwater Catfish Heteropneustes fossilis (Bloch)

Heteropneustes fossilis of either sex were total phospholipids, phosphotidyl choline, was exposed for four weeks at sub lethal concentration (0.002 ppm) during different phases of its annual reproductive cycle. Effect of exposure on plasma, liver and gonads phosphalipids have been worked out. Among total phospholipids, phosphotidyl choline, was found to be major component and next to that was phosphatidyl ethanolamine, phosphatidylinositol and phosphatidyl serine, respectively.
