1, site selection, loach culture in cement ponds should be built in a quiet area with ventilation, sunny, low terrain and convenient water intake and drainage. The following four factors should be considered when choosing the location of the pool: first, the location should be selected in high school, low school and low school; Second, the pool should be designed and built in a place where there is no shade and no fence to keep out the wind; Third, the water source should be rich, without industrial pollution and chemical pesticide pollution; Fourthly, the swimming pool should be built in a good and quiet environment, which is not affected by human and animal noise and mechanical noise.

2. After foundation excavation and site selection, rectangular and square water loach ponds can be built according to different geographical conditions and different planning and design. The area of the swimming pool can range from 10 square meter to 40 ~ 50 square meters. Generally, one pond is built at a time, and two or more ponds are jointly built and repaired, which can not only save investment, but also lay a foundation for raising loach in different ponds in the future.

3. When digging the ground to construct the pond, it should be noted that the bottom of the pond should be below the surface 1 meter, so that the temperature in the mud layer at the bottom of the pond can be basically balanced, that is, the temperature difference is relatively stable, which is conducive to the normal growth of loach during the breeding period or the safe wintering when people sting.

4. Construction of small loach pond. When building water loach pond, cement mortar is generally used as the wall. Wall height1.5m. After the pool is built, the inner wall should be polished to prevent leakage. The bottom of the pool should also be leveled with cement. Construction around the horizon should be meticulous to prevent water leakage after the pool is built.

5. During the construction of cement pool, two holes should be reserved, namely the water inlet and the drainage hole. The water inlet is located at the wall height 1 m; The drainage hole is located at the height of 0.2m The size of the hole can be flexibly determined according to the size of the swimming pool.

6. When constructing the drainage hole, you can insert the wine bottle outward from the inner wall. When the cement is semi-solidified, the wine bottle can be gently rotated and pulled out to make the water outlet sharp and firm. It will be convenient to use the wine bottle as a switch in the future. If sometimes the water level outside the pool is higher than that inside the pool, a fortress can be built at the outer end of the drainage hole. The fortress is 0.4 meters long, 0.3 meters high and 0.3 ~ 0.4 meters wide. When building the castle, a wine bottle is also stuffed in the castle, so that the tip of the bottle neck is opposite to the tip of the wine bottle in the inner hole. When the cement is semi-solidified, the wine bottle in the castle is pulled out. In this way, no matter whether the water in the pool is large or the water outside the pool is large, the wine bottle at the drain will not be squeezed out because of the pressure of water. If the wedge of the lid leaks, you can put a little mud in the hole and put it in the bottle. At this time, you will find that the bottle is blocked with water.

7, buried in the soil, after the completion of the cement pool, often water wet, a week later, the cement completely solidified, you can dealkalize. After 5 ~ 7 days of dealkalization, the soil can be buried.
