With the development of aquaculture, is it feasible to raise loaches in cement ponds?

Loach farming is not a very popular breed at this stage, which is mainly related to the demand of China's loach market at this stage. China's loach market is not very ideal, and at this stage, very large enterprises that breed loaches usually combine the Chinese market with exports.

The whole process of loach breeding using the cement pond feeding method is not very much at this stage, which is related to the cost of cement ponds, the cost of cement breeding loaches at this stage is more than 100 yuan, such a cost of production makes many farmers unwilling to adopt.

On the other hand, it is simple to raise loaches in cement ponds, which causes loaches to have a sense of trauma, because the walls of the cement pond are very rough, and the loach breeding density is usually very large, and the loach likes to swim frequently, which is easy to cause loach trauma, coupled with the large feeding density, it is easy to cause the loach to have a collective feeling, resulting in a large-scale death of the loach. In addition, the cement pond usually has limited space, and the water quality of the cement pond changes very quickly, which is difficult to meet the natural environment of water quality required for the growth of loaches. Therefore, at this stage, very few people adopt the method of raising with cement ponds.

Judging from the loach market at this stage, friends who want to breed loaches try to study the local loach market, for example, if you breed loaches in my hometown, the result must be very bad, because there is no habit of eating loaches in our local area, and the locals think that the smell of loaches is too strong, and they usually don't like it very much. Therefore, for such areas, it is better not to consider loach farming.

On the other hand, I hope that friends who want to engage in loach breeding remain rational, at this stage, there are many people engaged in loach hatching, but there are not many people who really rely on loach products to raise and get rich quickly. This is mainly due to the fact that the hatching of loach seedlings is very simple, so farmers who do special loach seedling hatching will of course promote how good the development prospects of loach farming are and how they can make money. However, only farmers who are really engaged in product breeding know the way inside.

In the last is the most critical point - technology, if your breeding technology is not at home, try not to touch this kind of technical requirements of the aquaculture industry, at this stage of loach farming is still in a very weak stage, a lot of infrastructure is not very perfect, so for inexperienced farmers are still a big challenge.

It is feasible to raise loaches in cement ponds, and after the new cement pond is built, it is necessary to soak it in water with an appropriate amount of black powdered phosphate fertilizer for 1 week for dealkalization. After the loach seedlings enter the pool, keep a slight running water at night.

Not feasible because loaches need dirt and they are not suitable for living in clean water.

Of course, it is possible to raise loaches in cement ponds, but the cement must be sterilized.

Loaches should be raised in pollution-free areas, the water needs to be live, and the anti-drilling hole runs with bricks embedded in the soil 50 cm to achieve a natural state. Density, temperature, water depth, and reproduction all need to be explored. Loaches and eels need to be fed alive, flies and maggots are better fed, and the pool should be as deep as possible.

1. Imitate the natural environment.

Don't talk nonsense if you don't understand, the landlord will lose a lot.

Cement pond breeding, must be soaked in water and exposed to the sun for a month, otherwise how many people will die. The four corners of the cement pool should also be treated without angles, and the plane must be polished and smoothed, or the cement proportion must be heightened. Hope to adopt.

The water temperature is 18---28, which is the best temperature to keep it.

The survival rate of loaches is still relatively high, you can put some soil in the field or cement pond, put some soil in it, and then plant some lotus roots, there are plants in it can form an ecosystem, nutrients and materials are supplied, I was in the Oriental Aquatic Textbook Network when I was studying, I learned about it on the Oriental Aquatic Textbook Network, and after returning to my hometown, I told the people in the village, you can explore it yourself.

Rearing Pond Construction:

Choose a place with good sunlight, warm and ventilated, convenient transportation, sufficient water sources, convenient intake and drainage, and no pollution sources within 3 kilometers to build a breeding pond. The soil of the loach pond is neutral or slightly acidic clayey soil. The area is 100 300 square meters, the depth of the pool is 80 100 cm, and the depth of the water is 30 50 cm.

One is that loaches have one characteristic, which is their absconding. Due to its small size, it can get out as long as there is a small gap. If there is a hole in the pond, the loaches can even escape in a day.

So, when building a pond for loaches, this point needs to be paid special attention. Also at the bottom of the treated pond. After the excavator digs out the pond, the bottom of the pond must be tamped solidly.

The second is to deal with the edge of the pond. A trench nearly 1 meter deep is dug along the edge of the pond and a thick plastic sheet is spread from the bottom of the trench to the ground, and the joints of the plastic sheeting must be tightly connected. After spreading the plastic sheeting along the edge of the pond, the plastic sheet is compacted with the excavated soil so that it is connected to the pond.

The upper end of the plastic sheet is fixed with a wooden stake every 1 meter or so to ensure that the plastic sheet is not blown away by the wind.

The third is to treat the inlet and outlet of the pond. Because the cost of PVC pipes is relatively cheap, farms can consider using PVC pipes as the inlet pipe of the pond, one end of which comes from the water lifting equipment at the side of the reservoir, and the other end directly leads to one side of the pond. Fourth, the outlet of the pond needs to be carefully designed, we hope that the water pumped out is the bottom water of the pond, the bottom water of the pond has loach fecal pollution, and the remaining feed pollution, so the water quality is poor, and when changing the water, it is necessary to discharge the water with poor water quality.

Pond cleaning and disinfection: 15 days before the loach seed stocking, the pond is cleaned and disinfected with quicklime. The water in the pond is 10 cm deep, and 100 grams of quicklime water is used per square meter to splash the whole pool.

The output of loach breeding is more or less, which is also related to the choice of site to build a pond, so what kind of site should be selected for the construction of small loach breeding cement pond? 1 Selection of site The cement pond should be built in a quiet area with ventilation, sunshine, low terrain and convenient access and drainage. When choosing a site to build a pool, the following four factors should be considered:

First, the venue should be selected in the low and high of the high school; Second, the pool should be designed and built in a place without shade and walls to block the wind; Third, water sources should be abundant and free from industrial pollution and chemical pesticide pollution. Fourth, the pool should be built in a place where the environment is good, quiet, and free from noisy livestock and mechanical noise. 2 After the excavation site is selected, according to different geographical conditions and different planning, the cement loach pond of rectangular and square village can be designed and constructed. The size of the pool can be as small as 10 square meters and as large as 40 to 50 square meters.

Generally, a pond is built at one time, and two pools or multiple pools are jointly built, which can not only save investment, but also lay the foundation for the future feeding of loaches. When digging the foundation to build the pond, it should be noted that the bottom of the pond should be lower than 1 meter below the surface, so that when the loach is cultivated in the future, the temperature in the mud layer at the bottom of the pond can be kept basically balanced, that is, the temperature difference is relatively stable, so as to facilitate the normal growth of the loach breeding period or the safe wintering when the person is stung. 3 Construction of small loach ponds When building cement loach ponds, cement mortar is generally used as a wall.

The wall is meters high. After the pool is built, the interior wall should be whitewashed so that it does not leak. The bottom of the pool should also be leveled with cement.

Meticulous construction should be carried out around the horizon to prevent water leakage after the pond is built. In the construction process of cement pool, two holes should be left, namely the water inlet hole and the drainage hole. The water inlet is located at a height of 1 meter on the wall; The drainage hole is located at the height of the wall.

The size of the hole can be flexibly determined according to the size of the pool. When building the drainage hole, a wine bottle can be stuffed into the hole from the inner wall outward, and when the cement is semi-solidified, the wine bottle is gently rotated and pulled out, so that the water outlet hole is a sharp bottle of wine bottle. In the future, it is very convenient to use the wine bottle as a switch.

If sometimes the water level outside the pool is higher than the water in the pool, a fort can be made at the outside end of the drainage hole. The fort is meters long and meters wide in meters high. When the fort is built, a wine bottle is also stuffed in the fort, so that the tip of the wine bottle neck is opposite to the tip of the wine bottle in the inner hole, and when the cement is half solidified, pull out the wine bottle in the fort.

In this way, whether there is a large amount of water in the pool or a large amount of water outside the pool, the pressure of the water will not squeeze out the bottle at the drain. If the wedge of the lid is leaking, you can stuff a little mud into the hole and then stuff it into the bottle, and you will find that the bottle is clogged without leaking. 4 After the cement pool is built, it should be wet frequently, and after a week, the cement will be completely solidified, and then the dealkalinization work can be carried out.

After 5 7 days of dealkalizing, it can enter the soil.

The key is to prevent loaches.

Come drill a hole to escape and defend, snake, green.

Source frogs, birds, and dragonfly larvae eat du loaches, so when building ponds, it is necessary to build anti-escape walls and protective nets

The anti-escape wall can be buried around the pond with a waterproof and anti-corrosion material, and the protective net covers the pond with a small nylon net, and the protective net is not only to prevent snakes and birds, but also to prevent dragonflies from laying eggs, and dragonfly larvae will eat small loaches.
