According to the latest reports, since the beginning of 2025, nearly 2,000 hectares of shrimp farming areas in Vietnam have been affected by diseases, which has brought huge pressure to the local aquaculture industry and affected production and economic benefits. In this situation, the scientific use of disinfectants for water disinfection and effective disease prevention measures are crucial for protecting shrimp farms and reducing economic losses.

A Review of Shrimp Diseases
The current outbreaks mainly involve White Spot Syndrome Virus (WSSV) and Hepatopancreatic Necrosis Disease (HPND) - two common viral diseases in shrimp farming. These pathogens spread rapidly, especially under high-density farming conditions and unstable water quality. Once pond water becomes contaminated, shrimp survival rates drop sharply, directly reducing production and affecting export supply.
As one of the world's leading shrimp exporters, Vietnam's aquaculture industry is facing unprecedented challenges in disease prevention. To effectively block pathogen transmission and improve pond water quality, using disinfectants is one of the most efficient and economical solutions.
The Roles and Advantages of Disinfectants
Common disinfectants such as sodium dichloroisocyanurate (SDIC), trichloroisocyanuric acid (TCCA), and calcium hypochlorite (Cal Hypo) play a crucial role in the biosafety of shrimp farming.
By effectively eliminating harmful microorganisms in water, disinfectants can reduce the outbreak of diseases, improve water quality, and create a safer and healthier environment for the growth of shrimp.
During the outbreaks, the appropriate use of disinfectants can help shrimp farms quickly restore water health and protect production efficiency. The main application stages of disinfectants include:
1. Pond preparation before stocking
Before stocking shrimp, applying disinfectants to the entire pond helps eliminate bacteria, viruses, and parasites in the water and sediment. This significantly reduces the initial pathogen load and provides a clean, safe environment for shrimp larvae.
2. Routine disinfection during culture
During the entire farming cycle, shrimp ponds need to be replenished with water. At this point, it is necessary to use disinfectants to disinfect the replenished water. It should be noted that these disinfected replenishments can only enter the shrimp ponds when the available chlorine concentration drops to 0.
3. Disinfection of equipment and facilities
Feeders, aerators, pipes and tools should also be disinfected regularly to prevent bacterial attachment and spread, ensuring the overall hygiene and disease control of the farm.
4. Cure
When diseases occur in shrimp ponds, such as Black Spot Disease, SDIC disinfectant should be used to sprinkle and disinfect the entire pond.
Application Methods and Best Practices
Dissolution Method: After dissolving disinfectants in clean water, add them evenly to the pond surface to ensure uniform distribution and maximum effectiveness.
Circulation System Application: Add disinfectants through a water circulation or pumping system to achieve fast and even dispersion throughout the pond.
Intermittent Dosing: During high-risk or intensive farming periods, apply small, controlled doses in batches to maintain continuous disinfection effects without harming shrimp.
Supporting Sustainable Shrimp Farming in Vietnam
The sustainable growth of Vietnam's shrimp industry depends on scientific water management and disease prevention. Using professional disinfectants not only helps suppress pathogen spread but also improves aquaculture ecology, ensuring stable yields and long-term profitability.
As a professional disinfectants supplier, we provide a wide range of efficient, safe, and cost-effective disinfectants tailored for the Vietnamese aquaculture market - including both chlorine-based and non-chlorine-based options. If you have any needs, welcome to contact us.
In addition to shrimp ponds disinfection, wastewater treatment is also a key link in aquaculture. Aquaculture wastewater contains microbial residues and water nutrients. If it is directly discharged into the environment, it will cause serious water pollution and damage the aquatic ecosystem. Through scientific wastewater treatment, pathogens can be further removed, nitrogen and phosphorus emissions can be controlled, and water quality can be improved, thereby ensuring environmental safety and compliance with environmental protection regulations.

By integrating shrimp ponds disinfection and wastewater treatment, farmers can establish a safe, efficient and sustainable aquaculture system to reduce disease risks, protect the environment, meanwhile, achieve a win-win situation for the economy and ecology.
Conclusion
With the continuous development of Vietnam's shrimp industry, effective disinfection and water management have become increasingly important. Cooperating with reliable disinfectants suppliers can ensure the acquisition of high-quality products, technical support and sustainable disease prevention solutions, helping farmers ensure production and maintain their competitiveness in the global shrimp market.
