Effect of Endosulfan (EC 35) on Oxygen Consumption Patterns and Gill Morphology of the Indian Flying Barb, Esomus danricus

摘要

The Indian flying barb, Esomus danricus was exposed to three sub lethal concentrations of endosulfan EC 35 (0.49, 0.049 and 0.0049 μg l-1) to determine changes in the oxygen consumption patterns and gill morphology. The rates of oxygen consumption declined, while the gills showed various histopathological changes including marked epithelial lifting, lamellar fusion, hyperplasia, hypertrophy, mucus secretion, mucous cell proliferation, vascular congestion and blood sinus constriction after 28 days of toxicant exposure. Higher doses of exposure had more severe effects. Ceylon Journal of Science (Bio. Sci.) 41 (2): 145-150, 2012 DOI: http://dx.doi.org/10.4038/cjsbs.v41i2.5384
