Treatment of methemoglobinemia may consist of adding chloride (usually as sodium chloride) to the water. The rationale is that the chloride ion and nitrite ion are competing monovalent anions for limited number of uptake sites across the gill epithelium. The management strategy is to establish a ration of Cl:NO2 of at least 5:1. This is thought to reduce the uptake of nitrite by the fish to the extent where the natural methemoglobin reductase enzyme system in the fish can convert the methemoglobin back to hemoglobin. An additional managment practice may be to reduce the amound of feed given to the fish.
