Notes:
Alterations in the liver histology of Labeo rohita were examined after exposure to different concentrations of carbofuran (0.06 and 0.15 mg L−1) and cypermethrin (0.16 and 0.40 μl L−1) for 28 days. Histological recovery was also studied by maintaining the intoxicated fish in a freshwater system for an additional 28 days. Major damages caused by carbofuran toxicity were diffuse necrosis, cordal disarrangement, individualization of hepatocytes, etc.; significant changes induced by cypermethrin were hyperplasia, disintegration of hepatic mass, focal coagulative necrosis, etc. In both cases, damages were dose-dependent, with cypermethrin exhibiting more sensitivity than carbofuran. In all cases, recovery was prominent and rate of recovery was faster with carbofuran than when using cypermethrin.
