Acute toxicity of potassium permanganate to milkfish fingerlings, Chanos chanos

Abstract

Potassium permanganate (KMnO₄) is a strong oxidizing agent and is commonly used in aquatic systems to improve available oxygen, treat infectious diseases and parasites, detoxify fish poisons, and control algae. The following study was undertaken to determine the 24- and 96-h median lethal concentration (LC50) of milk fish (Chanos chanos)) fingerlings to KMnO₄. The study was also designed to evaluate the histopathological response of fish tissues to KMnO₄ but was reported in another paper (Cruz and Tamse 1986).
