Preliminary Report On The Use Of Potassium Permanganate To Produce Oxygen And Counteract Hydrogen Sulfide Gas In Fish Ponds

Potassium permanganate is dissolved in fish hatchery ponds and minnow hatchery ponds at the rate of from two to six parts per million to produce oxygen during acute oxygen shortage caused by excessive organic decay and to counteract hydrogen sulfide gas during seining operations. Potassium premanganate treatments are also used as prophylactic measures to prevent expected oxygen depletion. Empirical evidence indicates the efficaciousness of these treatments. A specially designated boat for the application of the chemical to the water was developed.
