If you have a small fish pond at home and want to raise fish, what should you pay attention to?

With the increase of living standards and leisure, people began to raise fish. <>

I think fish farming is a great science, and if you are not careful, the fish will be wiped out. The first is to choose a place to raise fish, according to the type of fish and business model, choose the best geographical location, fully consider the sunshine, water, electricity, soil pollution and other factors, as far away as possible from the location of residents to discharge sewage, to prevent fish from being polluted.

Then there is the construction of fish ponds, large-scale fish farming, fish ponds should not use reservoirs, because the water area is wide, the water level is deep, will cause waste of feed, and it is not suitable to use dams or lakes, because there is too much silt, fish are easy to be infected with pests and diseases, resulting in a large number of fish death. Good selection of fish fingerlings can reduce the mortality rate of fish fry in the process of transportation, improve the survival rate and disease resistance of fish fry in the breeding process, thereby reducing the risk of breeding and saving the cost of breeding. <>

Also, before selecting the fingerlings, you should visit the market. Find out what fish species are good to raise and what fish are easy to sell. Combined with the advice of the local agricultural department, we will purchase fish fry bases designated by the state or with relevant qualifications.

When buying fingerlings, the main thing to look at is the variety and activity of the fry, as well as to observe whether the body shape of the fry is uniform, whether the body color is shiny, and whether the gills and scales are normal.

Finally, there is polyculture of multiple types of fish, through which the utilization rate of feed can be improved, the water quality can also be improved, and the most important thing is to increase the total production. Polyculture should be divided into primary and secondary, the main fish is the main object of feeding, and the secondary fish is the main object of feed feeding, and the secondary culture achieves the purpose of purifying water quality by eating aquatic plants and residual feed. Common main fish are:

Grass carp, silver carp, bighead carp, dace, carp, etc., I believe that as long as the fish farmers know, a good fish pond filter can protect the health of the fish, can make the water quality of the fish pond clear, can save a lot of trouble for fish farmers, when the time is not very much, the filter can play a full role.

It is necessary to choose a suitable place to consider the problems of water source, electricity, transportation, etc., to avoid pollution in a relatively high place to build, to choose the construction materials of the fish pond, to choose red wood, stone and other materials to improve the grade, and to pay attention to the waterproofing of the inside of the pool and the red cliff.

In the process of raising fish in the small fish pond, you must choose the right fish, some fish can eat each other. Try to choose fish of the same species.

Remember to buy an oxygen machine. The water temperature should be correct. Prepare the fish. Don't let any oil fall into the fish pond. Prevent leaks in the fish pond.

Summary. Hello dear, the following aspects are needed to deal with 1. Surface treatment carbonates the surface of concrete, that is, the calcium hydroxide in the capillary pores of the surface layer is converted into insoluble calcium carbonate. For example:

Add well water to the newly built cement pond or expose the cement pond to the sun. Veneer material is added to the outside of the concrete to isolate the concrete from the water medium. Tiles can be used where possible, usually with plastic veneer.

2. To improve the compactness rate of concrete, vibration and other methods are used to make the concrete dense, and it is difficult to erod aquaculture water, and the amount of calcium hydroxide dissolved is relatively reduced. In short, the new cement pool can not be used in a hurry, so as not to cause economic losses.

Hello dear, you need to guess the following aspects of treatment: 1. Surface treatment carbonates the surface of concrete, that is, the calcium hydroxide in the capillary pores of the surface layer is converted into insoluble calcium carbonate. For example, adding well water to the cement pond of the newly built negotiation or exposing the cement pond to the sun.

Veneer material is added to the outside of the concrete excavation soil to isolate the concrete from the water medium. Tiles can be used where possible, usually with plastic veneer. 2. To improve the compactness rate of concrete, vibration and other methods are used to make the concrete dense, and it is difficult to erod aquaculture water, and the amount of calcium hydroxide dissolved is relatively reduced.

In short, the new cement pool can not be used in a hurry, so as not to cause economic losses.

<>Hello dear, you can follow the above methods.

Dear, hello, I am glad to answer for you, the newly repaired cement pond needs to be dealkalized first, and then the pond is cleared, and the fish can only be raised after water injection and fertilization. Usually before raising fish, 5 kg of salt per mu should be used to sprinkle it into the whole pond, and there can be a small amount of water in the pond, and the water level should not exceed 50 cm. The salt itself has a disinfecting effect and can also be soaked before stocking the fry.

If you use white ash, you need to have a water depth of about 1 meter, so that you can splash 15 kg per mu, and you can release fish to test the water for a week after splashing.

The tools required for fish farming and the surrounding environment of the fish pond were thoroughly disinfected, and the fish pond and injection and drainage facilities were inspected again. After comprehensive disinfection, the fish pond was turned off again, and the water quality of the Yingchun fish pond was regulated and the water quality was properly fertilized. Appropriate organic fertilizer can be applied to the fish pond to cultivate the natural bait needed for the cultivation of fish.

In particular, novice fish farming can refer to it. In the actual breeding process, according to the specific conditions to operate, for novice fish farming, it is recommended to go to the successful breeding farm to learn to visit, after inquiring about the relevant information, master the relevant technology and then carry out breeding.

First of all, there is a drawing about the inlet and outlet waterway and the water circulation system.

Then during construction, waterproof glue needs to be added to the cement.

Economical, usable, beautiful, depending on personal preferences and environmental conditions, in short, a good mood!

The alkalinity of the newly repaired cement fish pond is too high, and the pH value needs to be lowered first due to the slow release of alkalinity. So you can pour a bottle of white vinegar into the pond every day, so that for a week, the alkalinity has basically dropped, and then release the water and replace it with new water, and you can raise fish.

The key to fish farming is filtration, which mainly filters the feces of the fish. Toxins in the water are produced by the feces of the fish. The basic purpose of filtration in fish farming is to remove ammonia poisoning from the decomposition of fish manure in the water.

This can only be achieved through biofiltration, a type of nitrifying bacterium that uses ammonia in fish feces as nutrients. They can convert the toxicity of ammonia into substances that are harmless to fish, making the water body non-toxic, making fish healthy and less sick.

If the fish tank lacks an epiphytic area for nitrifying bacteria, there are few nitrifying bacteria and the fish manure cannot be treated in time. The ammonia content in the water body is high. Fish that live in ammonia poisoned water for a long time will gradually become weak and susceptible to water viruses.

Just like in the space where humans live, there will always be all kinds of viruses in the air, healthy people are not susceptible to viruses, and weak people are also prone to diseases. Therefore, timely removal of ammonia poisoning in fish feces is the fundamental guarantee to ensure fish health and reduce diseases.

Once the cement has cured, it is ready to use. No special handling is required.

If you don't soak in the pool, the cement will be alkaline when it encounters water, and you can't feed the fish, so you must soak the pool with a high concentration of glacial acetic acid in accordance with the proportion of the water volume in the pool.

Brush the waterproof paint a few times, then soak the pool with acetic acid, change the water more and then you can use it.

The newly built fish pond is first alkaline, and caligin can be used.

There is no need to change the water all year round, the water is clear and the fish are pleasant.

The new pond needs to be dealkalized with glacial acetic acid for about a week, and then raised in water with a KLJ fish pond filter for a week, and the fish can be released.

The cement is alkaline, must be soaked in the pool, in addition to the alkali in the use of fish pond fish, with glacial acetic acid soak for about a week, you also need to do a set of filtration system, you can use the Syrpu, fish first raise water, water quality is good, in order to raise good fish.

Soak the pond for dealkalization, and then put new water and raise good water to raise fish.

Do the dealkalizing treatment, there is a filter to raise fish.

New fish ponds need to be soaked in glacial acetic acid for at least a week or soaking, and the concentration should be high.

The new fish pond is because of the cement.

Therefore, it is necessary to remove alkali, otherwise there is no way to use the fish pond.

Soak in high-concentration glacial acetic acid for about 7 days.

The newly built fish ponds need to be dealkalized, 10 tons of water put one kilogram of glacial acetic acid, soaked for 7 days, the water is released, and the fish can be released after filtering with a caliginin filter.
