Toxic effect of potassium permanganate on Oreochromis niloticus based on hematological parameters and biomarkers of oxidative stress
Potassium permanganate (KMnO4) is an oxidizing agent used in aquaculture for many years. Despite its known efficacy for the treatment and prevention of fish diseases, information about their potential toxicity in non-target organisms is still very limited. The objective of this study was to evaluate the sublethal effects of potassium permanganate (1.0 and 4.0 mg L-1) on Nile tilapia, Oreochromis niloticus, using...
