Abstract The 96‐h LC 50 ˈs for potassium permanganate (KMnO 4 ) ranged from 0.750 mg/liter with channel catfish, Ictalurus punctatus, to 3.60 mg/liter with goldfish, Carassius auratus, in laboratory tests. The toxicity of KMnO 4 to fish is greatest in water of lower temperatures, in harder water, or in higher pH water. KMnO 4 is effective for detoxifying the fish toxicant antimycin in laboratory waters of pH 6.5 to 9.5. The half‐life for antimycin exposed to 1.0 mg/liter of KMnO 4 ranges from 7 to 11 minutes in the different pH waters at 12 C.
