Toxic effects of mercuric chloride, methylmercuric chloride, and Emisan 6 (an organic mercurial fungicide) on ovarian recrudescence in the catfish
Mercurial toxicity in fishes has been focused mainly on tissue uptake and subcellular distribution, nephrotoxicity, development, hatching and survivability of young ones and teratology. Very few studies have been attempted to investigate Hg toxicity on gonadal activity of fishes throughout the breeding season. In a previous investigation the authors have studied the toxic effects of mercuric chloride (HgCl/sub 2/), methylmercuric chloride (CH/sub 3/HgCl) and emisan 6 (an alkoxyalkyl fungicide) on the survival and histology of the kidney of the catfish, Clarias batrachus. The present report deals with toxic effects of these mercurials on ovarian recrudescence in the catfish, an economically important species in the subcontinent.
