Disinfectants are a kind of commonly used agents in aquaculture. Disinfectants are inseparable from the cleaning of ponds in the early stage of aquaculture, medicated baths before seedlings, disease prevention in the middle and later stages, and even daily water quality adjustment.
The rational and scientific use of aquaculture water disinfectants can eliminate or kill pathogenic microorganisms in the water body and prevent fish and shrimp diseases.
According to different water sanitizer for aquaculture, use them according to the instructions for use, and pay special attention to the various precautions mentioned in the instructions.
First add enough water to the container, and then add the aquaculture water disinfectant to dissolve it. After it is completely dissolved, sprinkle the aquaculture water disinfectant evenly over the whole pond. The sprayer should face the wind direction and start from the downwind.
Avoid direct contact with the liquid medicine. For highly irritating medicines (such as chlorine preparations, etc.), you should avoid taking the medicine for too long at high temperature. When the high temperature in summer is above 32°C, the duration of each spraying of aquaculture water disinfectant should not exceed 2 hours.
Disinfectant should be used with that the potassium monopersulfate uses in aquaculture when the water surface is large and the water depth exceeds 2 meters, and the interval disinfection method should be used. That is to say, only half of the medicine is used at a time, half of the water surface is disinfected, and the second medicine is used at an interval of more than 4 hours.
In order to avoid the use of aquaculture water disinfectant when the water body is deficient or the weather deteriorates, the pond should be patrolled in time after disinfection, and fish, shrimp and water problems should be solved in time.
It is forbidden to discharge the water body of the disease. If the water needs to be changed during the disease, the corresponding disinfection spray should be used according to the type of disease, and the discharge should be carried out after 24 hours of disinfection. For the sewage with pathogens from greenhouse farming, a sewage collection pond should be set up and disinfected for more than 24 hours before discharge.
Disinfection of the dead fish is prohibited. In order to prevent the spread of pathogens, a small amount of dead fish can be temporarily placed in a special lime tank, and the dead fish should be buried or incinerated for a long time.
Sprinkle quicklime or trichloroisocyanuric acid powder aquaculture water animal facility disinfectant into the pit for disinfection, and at the same time, a windbreak board should be installed at the pit mouth to prevent the spread of pathogens with the wind.
The growth of aquaculture is driving production and bringing more challenges, including disease management, food safety, pollution control and cost efficiency.
Disease management is a key challenge when ponds are high in manure, decomposed feed and ultimately bacteria and fungi. Pathogenic organisms develop rapidly under such conditions.
The management of organic matter, oxygen and ammonia concentrations is a key activity in pond management, and tools for managing these aspects include probiotics and specialized aquaculture water disinfectants, including Roxycide™.
Effective and correct water disinfection can reduce the incidence of fish, shrimp, crabs and other aquaculture products, as well as the use of drugs, which can reduce the cost of some aquaculture.
