Potassium Permanganate is a powerful oxidizing agent that can be used as a disinfectant for aquaculture facilities, fish seeds, and fish bodies. It is effective in preventing and controlling bacterial fish diseases, disinfecting fishery production equipment and tools, and acting as a "three smalls" (small toxicity, small side effects, small dosage) traditional fishery medicine for bacterial disease prevention in aquatic animals.

1. Main Applications

Potassium Permanganate is mainly used to prevent and control bacterial diseases in fish and fungal diseases in aquatic organisms within aquaculture environments. It is effective against conditions such as fish Saprolegniasis, turtle and frog skin mold disease, eel Vibrio disease, gill rot, tail rot, red fin disease, shrimp filamentous bacteria disease, larval slime disease, yellow gill disease, shrimp and crab chytrid disease, fish nematode disease, anchor nematode disease, ringworm disease, uterine nematode disease in carp, wheelworm disease, and oral filariasis.

2. Water Quality Improvement

As a strong oxidant, Potassium Permanganate quickly oxidizes organic matter in water, reduces oxygen consumption caused by respiration, and directly or indirectly improves water quality.

3. Primary Oxygen Release

Potassium Permanganate releases primary oxygen in water, which combines with water molecules to form oxygen. This process avoids the issue of fast-acting oxygenators being affected by water temperature and prevents the formation of microbubbles that escape from the water surface, thereby ensuring prolonged oxygenation. In some regions, Potassium Permanganate is used as an oxygenator, with its solution sprayed throughout the pool to increase the dissolved oxygen content in the water.

4.Oxidation of Toxic Substances

Potassium Permanganate can quickly oxidize toxic substances in water, including toxins secreted or produced by harmful algae, nitrites, organophosphorus pesticides like trichlorfon and malathion, organosulfur pesticides like ferram, and ammonium compounds. Therefore, Potassium Permanganate solution is often used for gastric lavage in cases of pesticide poisoning in both humans and animals to eliminate the effects of these substances.

5. Precautions

When using Potassium Permanganate, it must be diluted to a concentration that does not stain fingers before being applied, to avoid corrosion damage to the gills. It should also not be used with iron or well water with high iron content, as iron ions can be easily oxidized to trivalent iron ions, eventually forming yellow-brown iron hydroxide colloids that may adhere to fish gills, causing suffocation and death.
