Fish pond aquaculture is a good direction for people in our country to get rich and increase income, and before using a fish pond for aquaculture, it is generally necessary to disinfect it first. Sowhat medicine should be used to disinfect a fish pond? How should disinfection be done?

1. What medicine should be used to disinfect a fish pond?

Usually, a pond that has been trimmed and renovated must be disinfected with medicine, as this can prevent the occurrence of disease and can also kill bacteria, pathogens and so on in the pond. However, not all agents can be used to disinfect a pond. The commonly used agents include:

1. Bleaching powder

The food industry widely uses bleaching powder as a sterilizing disinfectant; it is low in price, strong in sterilization power and good in disinfection effect. For example, it is used for sterilizing and disinfecting drinking water and fruits and vegetables, and it is also often used for disinfecting swimming pools, bathrooms, furniture and other facilities and items. In addition, it is also often used for bleaching oils and fats, starch, fruit peels and other foods. When using it, everyone should note that an aqueous solution of bleaching powder has an irritating and corrosive effect on the gastrointestinal mucosa, so accidental ingestion must be avoided.

2. Qingtangling

Qingtangling is a highly effective pond-clearing product that can effectively kill wild miscellaneous fish, shrimp, crabs, parasites in the water and copepods in marine and freshwater aquaculture ponds. At the same time, it also has a good killing effect on parasitic eggs such as sporozoans and dactylogyrus in the pond bottom mud and water. However, it should be noted that 10-15 days after pond clearing, a water test must be carried out, and only after confirming that there is no toxicity in the pond can fish fry be put in.

3. Quicklime

Quicklime has the best effect in pond disinfection. It can both disinfect and effectively kill pathogens (parasites, bacteria, etc.), improve the air permeability of the bottom substrate, regulate pH, enhance the buffering capacity of the water body, and promote the growth of plankton, thereby increasing the production capacity of the fish pond.

2. How should a fish pond be disinfected?

For fish pond disinfection, the medicine should be chosen according to the actual situation. In addition, the time and amount of disinfection should also be determined according to the actual situation.

1. Generally, for intensive fish ponds, ponds with relatively low water pH, and ponds where quicklime is often splashed, the effect is relatively good. If quicklime is used to disinfect the pond, then splashing quicklime over the whole pond should preferably be done after 3 p.m. on a sunny day. In summer, weather conditions such as high water temperature, warmth, and thunderstorms are not suitable for splashing quicklime over the whole pond. Moreover, quicklime splashed in a pond should be prepared and used immediately. When using quicklime for disinfection, avoid applying it together with acidic bleaching powder or chlorine-containing and iodine-containing disinfectants, trichlorfon, chemical fertilizers and so on. The interval between applications should preferably be more than 5 days.

2. If Qingtangling is used to disinfect the pond, it is best to dilute it 2000 times with pond water and then splash it evenly over the whole pond. If the water quality is relatively fertile or the water temperature is relatively low when spraying, the application amount can be appropriately increased.

3. If bleaching powder is used to disinfect the fish pond, the usual dosage is 20 grams per cubic meter. Dissolve the bleaching powder in water and immediately splash it over the whole pond. In addition, for safety, when splashing, be sure to stand upwind of the fish pond and wear a mask.
