Technical Abstract: Hybrid striped bass (female white bass Morone chrysops x male striped bass M. saxatilis) juveniles were exposed to potassium permanganate (KMnO4) in a series of static toxicity tests in waters composed of filtered (75 µm) well water or filtered well water diluted with deionized water. Estimates of mean 24-h LC50 (median lethal concentration) were 4.47 and 2.97 mg/L KMnO4 in waters having total alkalinities of 109 and 213 mg/L (as CaCO3), respectively. LC50 values were significantly different by the Student-Newman-Keuls means comparison test. These data demonstrate that the acute toxicity of KMnO4 to hybrid striped bass juveniles is lower in waters of lower total alkalinity and total hardness. Results indicate that hybrid striped bass juveniles are tolerant to therapeutically relevant concentrations of KMnO4 and such treatments in low alkalinity waters are safer than treatments at higher alkalinity.
