Usually, the repaired and modified ponds should be disinfected with drugs, which can prevent the occurrence of epidemic diseases and kill the bacteria and germs in the ponds. However, the disinfection of ponds is not available for all kinds of medicine. the commonly used agents include:

1. Bleaching powder

Bleach is widely used as a germicidal disinfectant in the food industry with low price, strong germicidal efficacy and good disinfection effect. For example, it is used for sterilization of drinking water and fruits and vegetables, as well as for disinfection of facilities and articles such as swimming pools, bathrooms, furniture, etc., as well as bleaching of food such as grease, starch, peel and so on. When using, we should pay attention to that the aqueous solution of bleach has a stimulating and corrosive effect on gastrointestinal mucosa and avoid accidental ingestion.

two。 Qingtang spirit

Qingtang Ling is a highly efficient pond cleaning product, which can effectively kill wild fish, shrimp, crabs, parasites and copepods in sea and freshwater culture ponds, as well as sporidia, ring worms and other parasite eggs in pond sediment and water bodies. However, it should be noted that the water should be tested 10-15 days after clearing the pond to make sure that there is no toxicity in the pond before putting into the fish fry.

3. Quicklime

Quicklime is the most effective in pond disinfection, which can not only disinfect but also effectively kill pathogens (parasites, bacteria, etc.) to improve the permeability of sediment, adjust pH value, enhance the buffer capacity of water body, and promote the growth of plankton, so as to improve the production capacity of fish ponds.

Second, how to disinfect fish ponds?

Fish pond disinfection should choose drugs according to the actual situation, and the time and quantity of disinfection should also be determined according to the actual situation.

1. In general, intensive fish ponds, ponds with low pH value of water, and often sprinkling quicklime have a better effect. If quicklime is used for pond disinfection, it is appropriate to sprinkle quicklime in the whole pond after 3 pm on a sunny day, and it is not suitable to sprinkle quicklime in the whole pond under the weather conditions such as high water temperature, warm temperature and thunderstorm in summer. And the quicklime sprinkled in the pond should be used now, and the disinfection of quicklime should be avoided with acidic bleach or chlorine, iodine disinfectant, trichlorfon and chemical fertilizer, preferably at an interval of more than 5 days.

two。 If you use Qingtang Ling to disinfect the pond, it is best to dilute it 2000 times with water and then sprinkle it evenly throughout the pond. If the water quality is too fat or the water temperature is low during spraying, the application amount can be increased appropriately.

3. If you use bleach to disinfect fish ponds, the general dosage is 20 grams per cubic meter, and immediately sprinkle the whole pond after dissolving bleach in water. In addition, for safety, be sure to stand in the upwind of the fish pond and wear a mask.
