Can you use PP board to make a pond for raising yellow eel?

If you raise yellow eel, you can use PP board to make a pond, and this PP board can be used to raise yellow eel, and there is no problem.

It is not possible to use PP board to make ponds for raising yellow eels, and the best way to raise yellow eels is to use natural fish ponds or cement bottoms to make fish ponds.

You can use the pp version, there is no problem at all, and then use it relatively speaking, the cost is not very expensive, and it is very good.

Try not to pp this one, otherwise it may cause the death of the yellow eel due to toxicity. If you are satisfied, please give a trouble, I wish you a happy life!

No, raising yellow eels must be a pond and be grounded, otherwise the quality is not good.

Yellow eels can be raised with PP boards to make ponds, as long as a layer of mud is placed on it, so that the loaches can move on it at will, so that it is OK.

Yes, there are many ways to raise yellow eels, one of which is that you can use PP boards to make ponds, which is no problem at all.

You can't use PP board to make fish ponds, so that the growth of yellow eels will play a polluting role.

Hello, raising yellow eel can be used with pp pipes, to make a pond, what he needs is the nutrients and environmental conditions in the water, as long as it can hold water.

Can you use pp board to make a pond for raising yellow eel? In fact, raising yellow eels can't be talked about with pp boards, she wants him to hide in the mud to survive, and it will burrow.

Can you use PBA ponds to raise yellow eels? No, because PPA is a chemical product, and sunscreen can be cultivated in soil.

I think this should be possible to make a pond with pp board. The pond made of PP board is relatively soft and can provide nutrients, which is a good environment for raising yellow eels.

Of course, if you can use the pp version of the leather board to raise yellow eel, this material is still better, so there is no problem at all.

If you use this pp board to make a pond, I think it's still good and you can do it.

Hello, very happy with your question, raising yellow eel is not very good to make a pond with pp board, it is better to use traditional materials, I hope it can help you, thank you.

It's not impossible to do this, but if the design is very good, find relevant personnel to make a stricter and more precise model.

It is not reasonable to use plastic sheets for cultivating yellow eels, you can use cement boards or directly use fenced ponds.

Hello friend, this is okay, as long as there is water, it doesn't matter what other materials you use, thank you.

Yes, there is no problem with this pond.

Yes, as long as it is strong and retains water.

It shouldn't work, because this kind of yellow eel should be close to the ground, and it can't live without sticking to the ground.

I think that Huangshan City can make a canteen for Pipi Plate, and in this way, it can make him a little better, and can better protect the soil, I think this use effect should be able to save a little more.

This can be done, but it doesn't work very well.

You must check this, will it be harmful to you with this kind of board? Is it volatile formaldehyde or something? There is also raising yellow eel, the soil below, it likes to drill mud, you should have a certain amount of soil!

There are technical requirements for yellow eel, you have to. In case of people who have experience in raising yellow eel with yellow.

It should be okay to eat them.

A small fan can be used to make a pond in batches, Emperor Mengyao, I don't know how to decorate it.

pH in water, dissolved oxygen, water temperature.

One: how to maintain the pH value, if it is found that it is acidic, 3% of the quicklime water is splashed in the whole pool, if it is alkaline, 3% of the bleaching powder is splashed in the whole pool, and this method to adjust the water can also play a role in sterilization.

Two: water dissolved oxygen, refers to the amount of oxygen in the water, in the process of breeding yellow eel, if there is a lack of oxygen in the person, it will cause the yellow eel to suffocate, or probe out for a long time to breathe deeply, resulting in the yellow eel thin or dead, this is mainly because the yellow eel breeding density is too large or the yellow eel is wound into a pile, or secretion of mucus is too much, but also will cause the water temperature to rise, for this situation to appropriately reduce the breeding density, if the cage or cement pond soilless breeding, the density of each square is controlled at about kilograms of seedlings, You can also place a certain proportion of loaches, because the loaches are active, so the water can be fully oxygenated, and the yellow eel is not easy to be wound into piles, the ratio of loaches and yellow eels is 2-3%, and the proportion is too large to cause domestication or feeding difficulties.

Three: control the water temperature, if you can keep a slight flow of water, cover the shade net when it is hot, and cover it with insulation film when it is cold, so that the water temperature will be controlled to a certain extent. In addition, there must be sufficient aquatic plants in the cage or pond to occupy 80% of the area, which can also play a role in purifying water quality and cooling down.

The ridge should be wide and strong, and not leaking. There are a large number of aquatic weeds and dry grass growing around the ridge of the pond, and the water peanut can be transplanted without grass, accounting for about 30 of the whole pond area, in order to facilitate the habitat of the yellow eel. The water source is pollution-free, the injection and drainage are convenient, and the injection and drainage outlets are equipped with nets to prevent escape.

Clear the pond and fertilize the pond with quicklime. The water depth is 1 meter, 150 kg of quicklime is used per mu, and the whole pool is splashed with water. When the effect disappears, 1000 kg of manure is applied per mu, and after 7 days, plankton multiplies in large quantities, and fish fingerlings can be stocked.

Seed stocking. 1. Stocking of fingerlings. Generally carried out in late February, mainly to fatten water fish, 400 fingerlings per mu, including silver carp accounted for 50, silver carp accounted for 20, group head bream accounted for 15, silver carp accounted for 15, the average size of 10 per kilogram. The size of the silver carp is larger, and the tail weight is 200 grams, and the breeding fry are for the eel to feed.

The fingerlings are soaked and disinfected in 3 salt water for 10 minutes and then placed in the pond.

2. Eel seed stocking. In the peak season of yellow eel activities, cage eel species that are free of disease and injury, lively and natural swimming are collected. Before stocking, soak in 3 salt water for 5 minutes, and remove the irritable and jumping around.

The stocking specification per mu is 15 kg of eel species with 30 tails per kg, and the eel species are released at one time, and the specifications of eel species are relatively consistent.

3. Forage fish stocking. Appropriate stocking of wheat ear fish and loach, generally 20 kg per mu. They reproduce quickly, are smaller, and are easily preyed upon by eels. Loaches also have a certain income when they grow up.

Day-to-day management. 1. Fertilization. After June, regular application of phosphorus fertilizer and nitrogen fertilizer to fertilize water quality, 5 kg of superphosphate per mu in the morning of the first day, and urea 2 per mu in the morning of the next day? 5 kg, fertilizer water sprinkled throughout the pool, fertilization every 10-15 days.

2. Feeding. Feed the fish with some feed. The feed mainly includes cake meal, corn, bran, etc., which is appropriately added to make pellet feed and fed. The daily feeding amount is 3 5 per cent of the total weight of the fish eaten, twice a day.

3. Regulate water quality. If it is found that the pond fish is hypoxic and floating, turn on the aeration equipment in time to increase oxygen. In summer and autumn, new water is added once a week to ensure that the water quality is "fertile, lively, tender and refreshing".

4. Disease prevention. Starting from June, the pool water will be disinfected every 20 days, with 20 kg of quicklime or 1 kg of bleaching powder per mu each time, and the water will be sprinkled throughout the pool. Feed regularly with medicinal bait.

5. Adult fishing. Large-sized adult fish are harvested in batches and marketed to maintain appropriate breeding densities. Insist on using big-eyed nets and wire nets to fish, and try not to fish in dry ponds throughout the year to prevent yellow eels from being injured.

According to the market, the first fishing of yellow eel on the market, it is generally required to catch more than 150 grams of yellow eel on the market, catch the big and keep the small, and the fishing methods include net trapping, eel cage trapping, etc.

Pond stocking is not recommended, now many yellow eel farmers are like this, lost a lot or use the latest cage farming methods are better But if you have your own opinions, or tell you 1selection of natural conditions; The ponds for breeding yellow eels are generally built in places that are sheltered from the wind and the sun, have sufficient water sources, have no pollution in water quality, and are convenient for intake and drainage. 2.

Construction of ponds: Yellow eel breeding ponds can be rectangular or square, and the depth of the pond is required to be meters. Breeding ponds are divided into two kinds of earth ponds and cement ponds, the ridge of the earthen pond should be built with hard soil, the bottom of the pond ridge is 0 meters wide, the top of the pond ridge is 0 3 meters wide, the bottom of the pond is tamped, and the walls and bottom are pressed with plastic film or plastic rainproof cloth.

Contiguous ponds should be uniformly designed and constructed with inlet and drainage systems, and water inlets and drainage outlets should be equipped with anti-escape and anti-leakage facilities. 3.Bottom Condition:

The pond of breeding yellow eel requires that there is a meter thick, rich in organic matter of silt, the river mud with grass can be dug up in early spring every year, the pond is released, and the water hyacinth, water peanut, water white and other aquatic plants are planted, so that the coverage rate of aquatic plants in the breeding pond reaches about 30, when stacking the ridge, pay attention not to make the water body of the pond form a dead angle, affect the effect of water exchange. 4.Remove wild trash fish:

Before stocking eel seedlings, fish with low economic value, competing with eel seedlings for food and harming yellow eel seedlings should be removed from the pond. At the inlet and outlet of the pond, the fish trapping facility can be made with centimeter mesh mesh. 5.

Pond cleaning and disinfection: When the natural water temperature reaches 10 or more, it is necessary to prepare for the first time by draining the pond and exposing it to the sun for 20 days. Then the pond around and the bottom of the clean, 10 days before the purchase of seedlings for drug disinfection, with quicklime 220 250 grams of square meters, with 10 cm of water, after the quicklime is dissolved, while the whole pond is splashed while it is hot, completely kill the harmful bacteria and parasites at the bottom of the pond, create a good and stable pond environment.

First, the selection of the construction site of the yellow eel breeding pond can use some waste water bodies that are not suitable for breeding other fish, and can also be cultivated in puddles and ponds that are not suitable for planting crops, or in the water bodies where water chestnuts, lotus, and water chestnuts are planted. The pond where the eels are kept should be located near the residence and should be ventilated to the sun. Ponds should be built in a place where there is water, so that they are warm in winter and cool in summer, with sufficient water and clean water.

2. The shape and size of the eel pond The shape of the eel pond can be designed in combination with the landscaping, which can be rectangular, square, round or oval. At present, rectangular eel ponds are widely used. The size of the pond depends on the size of the culture, from 2-3 square meters for small ponds and 20-100 square meters for large ponds.

The area of the family eel pond should not be too large. For a single pool, 10 15 m2 is generally appropriate. The depth of the pond water is generally the thickness of the potato, the deeper the better.

3. The structure of the yellow eel pond includes a brick pond and an earthen pond and a brick pond. Above-ground pools, underground pools, or underground pools can be constructed. The walls of the pond are made of brick or hand-rubbed stone.

The bottom of the pool is connected with cement, which can be paved with stone, yellow sand or concrete, and must be compacted. There should be no air holes left in the walls or bottom of the pond to prevent the tail of the yellow eel from escaping from the pool wall. There should be a water level difference at the bottom of the pool.

Make a hole in the wall 40 cm from the bottom of the pool and cover it with barbed wire. The hole is usually plugged and used to drain water during heavy rain. Once the pond is built, it is rinsed and soaked for a few days before draining.

The bottom of the pond should be covered with a layer of clay or river mud and grass made of more organic matter, and water should be poured before feeding, and the water depth should be about 10 cm. The earth pond should choose to dig a pond in a place with good drainage and irrigation conditions and hard soil, and make a ridge around the excavated soil. The ridge is 40 60 cm high and 60 80 cm wide, and the ridge should be layered and tamped to prevent the eel from escaping from the soft ridge.

Earth ponds are suitable for large-scale farming. In addition, large-scale industrial farming of eels has been carried out, cement ponds have been built for farming, and gravity rheological ponds have been constructed. Large sand tanks can also be used to raise eels at home.

Fourth, simulate the ecological environment of the growth of yellow eel at the bottom of the pond, first lay about 10 cm thick straw, and then put about 20 cm thick bricks and right blocks on the straw to artificially create some caves for yellow eels to live. Some aquatic plants like absinthe, water hyacinth, water hyacinth, etc. It can also be planted in the pond as a lurking eel in Huangsanzhou, blocking part of the sunlight, improving the pond environment, reducing the pond water temperature, and conducive to the growth of the eel.

Rational construction of eel ponds. The rearing pond of yellow eel should be built in a sheltered place from the wind and the sun, close to the water source, and a small pond can be built in the open space in front of the house and behind the house, the soil pit, the edge of the ditch and the corner of the field. The area of the eel pond is generally 50 square meters - 100 square meters, for small-scale farming in the courtyard, each pond is about 10 square meters.

The depth of the pond is 1 meter, and it can be built with cement, stone, bricks and sandwich soil. The top of the pool wall should be made of bricks in a "T" shape, the top of the pool should be more than 30 cm above the water surface, and the inlet and drainage pipes and overflow pipes must be firmly closed with barbed wire to prevent the yellow eel from escaping. After the pond is built, 30 centimeters of soil is put into the pond, and then stones and bricks are thrown in to make the eels burrow.

About 10 centimeters of water is reserved on the mud surface so that the eel can stick its head out of the hole to observe feeding or breathing when burrowing. Finally, plant some aquatic plants on the surface of the pool, such as cocoon, mushroom, water lotus, etc., but it is required to occupy less than half of the water surface.
