Safe Use of Aquaculture Disinfectant

Disinfectants are the most commonly used medications in aquaculture. They are essential from the preparation of farming ponds, pre-stocking bath of fry, disease prevention, and even water quality regulation. Using aquaculture disinfectants reasonably and scientifically can eliminate or kill pathogens in the farming environment and prevent diseases. However, improper use may easily cause fish and shrimp poisoning and death. This article will introduce how to use aquaculture disinfectants scientifically and safely, hoping to help the majority of farmers use aquaculture disinfectants correctly in the future.

Precautions for Using Aquaculture Disinfectants

• Before using aquaculture disinfectants, carefully read the product instructions. Use the product according to the method and dosage strictly for different aquatic animals, paying special attention to the precautions mentioned in the product instructions.

• When disinfecting the entire pond, first add a sufficient amount of water to the container, then add the aquaculture disinfectants to dissolve them. After complete dissolution, evenly sprinkle the solution over the entire pond. When sprinkling the disinfectant, one should face away from the wind direction and start from the downwind side of the pond.
  

• When using aquaculture disinfectants, avoid direct contact with the liquid. For some highly irritating disinfectants (such as chlorine-based agents), avoid using them for extended periods in high temperatures. When the temperature is above 32℃, the application time should not exceed 2 hours.
  

• In larger ponds where the water depth exceeds 2 meters, the interval pond disinfection method should be used when applying aquaculture disinfectants. That is, disinfect half of the water surface with half of the disinfectant at one time, and the interval between the two applications should be more than 4 hours.
  

• After disinfection, patrol the pond promptly and address any issues immediately. Avoid using aquaculture disinfectants when the pond water is oxygen-poor, or the weather is deteriorating.
  

Treatment Methods for Diseased Fish Ponds

• It is prohibited to discharge the water from a diseased fish pond directly without any treatment. If it is necessary to change water during the disease period, use appropriate aquaculture disinfectants according to the type of disease, and discharge the water 24 hours later. For pathogen-carrying wastewater generated from greenhouse aquaculture, set up a wastewater collection pond and disinfect it with aquaculture disinfectants for more than 24 hours before discharging.

• Disinfection treatment of dead fish bodies. It is forbidden to discard dead fish randomly. A small number of dead fish can be temporarily placed in a dedicated lime tank. When there are many dead fish, they should be buried deep or incinerated. When burying deeply, sprinkle quicklime or trichloroisocyanuric acid powder in the pit for disinfection.
  

• In conclusion, the role of disinfectants in aquaculture should not be underestimated. They are not only an effective means of resisting pathogen invasion but also a key to sustainable aquaculture development.
