Aquaculture

Chlorine dioxide is a highly effective and safe disinfectant for aquaculture. It sterilizes and purifies water, leaves no carcinogenic residues, and is superior to traditional chlorine-based disinfectants. It requires low dosage, has stable effects, and is highly safe, and has been widely used in coastal areas and is being promoted to inland aquaculture areas.

Aquaculture farmers often blindly use chlorine dioxide to disinfect fish ponds, a practice that frequently leads to the death of fish and shrimp. While chlorine dioxide is effective at killing bacteria, safe, and does not induce drug resistance—making it a common choice in aquaculture—it requires proper activation and precise dosage control prior to use. It should be applied on sunny days and never mixed with other substances. Ultimately, disinfection serves only as a symptomatic remedy; the true foundation of successful aquaculture lies in the proper management of water quality, pond sediment, and feeding practices.
