                                Technical Abstract: The present research determined the acute toxicity of potassium permanganate (KMnO4) to the free-swimming Ich theront and the concentrations needed to prevent an initial or stop an active infestation of Ich in juvenile channel catfish.  Free-swimming theronts were exposed to concentrations of KMnO4 and observed for  4 hrs to determine the acute toxicity.  A concentration of 0.9 ppm KMnO4 caused greater than 95% mortality of the theronts in 45 min.  Channel catfish were exposed to theronts and immediately treated with a single dose of KMnO4 to determine the concentration needed to prevent an initial outbreak.  The study was ended when the control fish (untreated) became infested with Ich.  The lowest dose of KMnO4 that completely eliminated the Ich was 1.0 ppm.  In another study, juvenile channel catfish were  exposed to an Ich infested fish until they developed immature trophonts.  They were then moved to individual glass containers with 2 L of well water and were treated with doses of KMnO4 ranging from 0 to 1.5 ppm daily.  The study was ended when the control fish died.  The lowest dose of KMnO4 that completely eliminated the Ich was 1.25 ppm.
