New fish pond the most local anti-leakage method, new fish pond with what disinfection? What should I pay attention to?

The best way to prevent water leakage in the new fish pond is to tamp the bottom of the pond completely by mechanical compaction, and the yellow mud can be evenly applied to the bottom of the pond and then irrigated after natural air drying. What to disinfect the new fish pond: the new fish pond can be disinfected with bleach, Qingtang Ling and quicklime. What should be paid attention to in new fish ponds: cleaning up residual fish eggs, checking for leakage, disinfection and management of water quality.

1. The best way to prevent water leakage in new fish ponds

Generally speaking, leakage prevention can be carried out by laying plastic film at the bottom, which is a more convenient, simple and effective method, but it is not a long-term solution. The plastic film may be broken, or it can be compacted mechanically to completely tamp the bottom of the pond, which can effectively solve the problem of water leakage in the pond, or apply yellow mud evenly to the bottom of the pond and wait until it is naturally air-dried before irrigation. It can also effectively avoid water leakage at the bottom of the pool.

What kind of disinfection should be used in the new fish pond

1. Bleaching powder

Bleach is widely used as a disinfectant in the food industry because of its low price, strong germicidal efficacy and good disinfection effect. it is often used for sterilization of drinking water and fruits and vegetables. it is also often used for the disinfection of facilities and articles such as swimming pools, bathrooms and furniture, as well as the bleaching of food such as oil, starch and peel, but it should be noted that the solution of bleaching powder can stimulate and corrode the gastrointestinal mucosa. It is necessary to prevent accidental eating.

2. Qing Tang Ling

Qingtang Ling is a highly efficient pond cleaning product, which can not only effectively kill wild fish, shrimp, crabs, parasites and copepods in sea and freshwater aquaculture ponds, but also kill parasitic eggs such as sporidia and ring worms in pond sediment and water. Generally, water tests should be carried out 10-15 days after pond cleaning to ensure that there is no toxicity in the pond before putting into fish fry.

3. Quicklime

Quicklime is effective in pond disinfection, which can not only disinfect, but also effectively kill pathogens, that is, parasites, bacteria, etc., while adjusting pH value, improving the permeability of sediment, enhancing the buffer capacity of water body, and promoting the growth of plankton, thus increasing the production capacity of fish ponds.

Third, what should be paid attention to in the new fish pond

1. Clean up the residual fish eggs

(1) the water source of newly dug fish ponds must be abundant. Most mariculturists may not know that some fish eggs are very tenacious. When you start to cultivate fish directly in the newly dug fish ponds, some other fish fry may be bred at a later stage.

(2) these fish are likely to carry infectious bacteria without safe treatment, which will affect the efficiency of culture in the later stage, so the newly dug fish ponds need to be dried first, and then released and recycled for about 2 times, which is conducive to the cleaning of residual fish eggs.

2. Check whether the water is leaking

New fish ponds are more prone to leakage, because now they are all excavated by machines, and the cracks accidentally dug cannot be seen. To check whether there is leakage, it is necessary to fill the pond with water, and then look at the degree of water loss. If there is no obvious change in the water surface within 1-3 days, it will prove that there is no leakage.

3. Disinfection

Pathogens may be hidden near the new pond, so you need to disinfect the surrounding area properly, put more disinfectant in the water depth, and less in shallow water, but sprinkle it in place.

4. Management of water quality

Fish farming has relatively high requirements for water quality, and fish farmers in most places have suffered great losses from water pollution, so newly dug ponds should do a good job in water quality management and do not allow contaminated water to flow into new ponds. At the same time, there needs to be a period of purification space between water sources and ponds, so there will be more protection.
