If you want to dig a small fish pond by yourself, what problems should you pay attention to?

For large-scale fish farming, reservoirs should not be used in fish ponds, because the water area is wide and the water level is deep, which will cause waste of feed. Dams or lakes should also not be used, because there is too much silt and fish are susceptible to pests and diseases. My personal suggestion is to rent about 10 acres of land and hire someone to dig the pond yourself.

The pond is dug into a regular rectangle and sits facing east. The pond has a depth of 2 meters, has an independent drainage and irrigation system, and the inlet and outlet show a certain slope. After the fish pond is dug, put 1 3 water and put 50 kg of quicklime per mu.

Carry out disinfection. After 40 to 50 days of disinfection, after testing the water without problems, the fingerlings can be put in.

<> fish farming is like raising pigs, not putting feed on time, it is not big to rely on drinking water, and putting feed not only on time, but also to control the amount of feeding, putting less fish can not eat enough, putting more and easy to cause fish to die of fullness. There are many ways to clean the water source regularly, disinfect and clean the water source of the fish pond, you can microcirculate the fish pond water every day, or you can splash it with strong chlorine or quicklime mixed with water, and disinfect and sterilize the fish pond every other week.

Especially in the hot summer, the outside temperature is high, the water temperature of the fish pond is high, it is easy to cause the fish in the fish pond to die of hypoxia, at this time you should in addition to the water microcirculation of the fish pond, but also to observe the movement of the fish in the fish pond every day, if you find that the fish in the fish pond continue to float in the pond, the fish are anorexic, and occasionally the fish die, you should quickly install an aerator in the fish pond, and supply oxygen to the fish regularly in the morning, noon and evening, until the White Dew Festival.

After that, the mortality rate of the fish can be greatly reduced.

Drying. Cement is a building material. After the construction itself is completed, there will still be a lot of cement ash on the surface.

So it has to go through a certain period of exposure. Even if you can't expose it to the sun, wait until the cement is completely dry. By fully drying the pool in the sun, the water vapor of the cement is evaporated and completely hardened.

This process may start with three to four days of drying. It is also necessary to water during this period to prevent cracking.

It is necessary to pay attention to the sanitation problems in the fish pond, to carry out sterilization and disinfection, to pay attention to the quality of the water when releasing the water, to ensure that the dissolved oxygen in the water is high, to ensure that the water source in the fish pond is sufficient.

First of all, the best location is to build a screen in front of the courtyard, and then dig a pond water behind the screen, which means wealth, in fact, it is to find a low-lying place, which will not occupy other important positions, far from the foundation of the house.

Of course, in a free place, because this or the yard looks very simple, and it makes it very easy for the small fish to survive.

Legal Analysis: Yes. An application is submitted to the village committee, and the villagers' representatives agree, sign the contract, and go to the county-level land management department for examination and approval, and register for the record.

Because it is likely that a change of land use will be involved. Therefore, it is necessary to complete the formalities, go through the notarization or go through the registration of the change of land contracting and management rights with the local people at or above the county level. According to land use planning, with the approval of the competent departments of agriculture, land, and agriculture, it is legal to dig fish ponds anywhere and return farmland to water, and it is illegal to dig fish ponds anywhere without approval, causing permanent damage to the land.

Legal basis: Rural Land Contracting Law of the People's Republic of China Article 19 Land contracting shall be carried out in accordance with the procedures of the collective economic organization, the villagers' meeting of the members of the collective economic organization elects the contracting working group, the contracting working group in accordance with the provisions of laws and regulations to formulate and publish the contracting plan, and convene a meeting of the villagers of the members of the collective economic organization in accordance with the law to discuss the demolition and dismantling of the contracting plan; Publicly organize the contract plan for the real bridge socks and sign the contract.

Be careful not to dig up oil

It hasn't been updated yet, and it can't be mined for the time being.

1. Select the site first, then find a suitable location, find an excavator to dig, the general depth is in meters, and the width is one-tenth of the length.

2. Disinfection of clear ponds. In order to remove toxic and harmful substances such as heavy metal salts that endanger the fish body, the pond must be soaked in water before stocking the fish fry, soaked for several days and then discharged, and repeated after exposure for a few days. 7-10 days before stocking fish fingerlings with quicklime thoroughly disinfected, generally dry pond per mu with 75 kg of quicklime slurry evenly sprinkled in the whole pool, or with water according to the water depth of 1 meter per mu with quicklime 150 kg of water sprinkling the whole pool.

3. Apply sufficient base fertilizer. When the third soaking pond is irrigated, basal fertilizer should be applied at the same time to improve the pond water fertility, promote the reproduction and growth of plankton, and provide sufficient natural bait for fish. The base fertilizer should be based on pigs, cattle and other livestock and poultry manure, generally 7-15 days before the fry are put into the pond according to 500-600 kg of fertilizer per mu.

4. Stocking fingerlings. Before the fry go down to the pond, the water depth is required to be about one meter, the water color is gray-white, and the general transparency is kept at about 30 cm; The water quality should not be too fertile, otherwise it will cause the death of the floating head of the fry. Fingerling stocking should be done:

Herbivorous fish are the mainstay, supplemented by ferticultural and omnivorous fish, and the fingerlings should generally be stocked in winter, and the size of the fry is required to reach more than 20 centimeters, and the deeper water body should reach more than 20 centimeters.

5. Fertilization and bait. Top dressing is mainly based on human manure and urine, chemical fertilizers, etc., and should be insisted on less application and frequent application, generally 150-250 kg of manure per mu. For the pond of breeding non-filtered fish, it is also necessary to feed compound feed and green feed according to the principle of "four determinations", and appropriately increase or decrease according to the specific situation, and the water color is brown.

6. Prevention and control of fish diseases. Frequently disinfect the fish body, bait table, tools, etc., once fish diseases are found, measures should be taken in a timely manner**, usually feed some garlic, vitamins, beneficial microorganisms, etc., can prevent common fish diseases. Fish culture in newly dug ponds is generally muddy, which affects fish respiration and plankton reproduction.

Quicklime should be sprinkled every 10-15 days according to 20-30 kg per mu of pond each time, which can not only sink mud and clean water, but also prevent fish diseases.

First, do a good job in construction planning. The construction of fish ponds should be based on the location, conditions, what species to raise, how large the size of the fish to raise, etc. Consideration should be given to the size of the fish pond to be built, how much earthwork to dig, how much water surface to build, how long it will take, etc.

And consider it according to the actual situation of the economy and labor. It is best to dig fish ponds in the year, raise fish in the year, and benefit in the year. Second, the choice of location.

It should be considered in several aspects, such as having a water source (or being solved by drilling wells and repairing canals), non-seepage soil, low investment, labor-saving, labor-saving, and quick results. 1. Build ponds in natural pits, oak pure shallow ponds, dry old river channels, old river forks, or low-lying land, with small investment and quick results. Labor and labor saving.

2. The soil quality of the pond is best to be clay or loam. 3. It is necessary to choose a place close to the water source such as canals and wells or convenient for water diversion to build a pool. 3. Fish pond standards.

1. Fish pond area: The size of the fish pond area should be determined according to the variety and size of the fish. Such as:

Breeding grass, scales, weaving, carp, weaving, squid and other fish, the area is about 10 acres; It is better to cultivate Nile tilapia with an area of about 3 acres or no more than 5 acres; Fish fry ponds for cultivating water flowers to summer flowers, each with an area of 2 acres per l; The fish ponds from Xia Huapei Town to the fingerlings are 2 to 3 acres each. 2. Fish pond depth: The depth of the fish pond is an important condition for fish production, as the saying goes

Raising big fish in deep water". The depth of the fish pond varies depending on the species and size of the fish raised.
