Common culture patterns of Loach

What are the common culture patterns of Loach culture? There are many culture models of Loach, such as pond culture model, cement pond culture model, cage culture model and rice field culture model. Let's take a look at it.

The model of raising Loach in pond

The model of pond culture of Loach is that Loach is specially cultured in the pond without any fish. The ponds commonly used for the cultivation of Loach can make use of fish ponds, ponds, soil pits, ditches and so on. Generally requires longer east and west, south and north width of 20-30 meters, an area of 3-5 mu, pool depth of 0.8-1.2 meters, water depth of 0.5-0.6 meters. The pool stem road surface is flat, the slope is consistent, do a good job of purse seine anti-escape, cultivate good water quality, transplant a small number of floating plants. The seedlings of "Nongke 10" are put in 400,500jin per mu, and the finished product of Loach can reach more than 3000 jin per mu after 90-120days, which is the main efficient culture mode in the Loach culture industry at present.

Model of cultivating Loach in cement Pond

The mode of cultivating Loach in cement pond has the advantages of convenient feeding and management, durable breeding equipment, easy fishing, good regulation of water temperature and so on. Generally speaking, the area of each pool is about 80-100 square meters and the depth of each pool is 0.8-1 meters. The bottom of the pond is covered with 15-20 cm fertilizer mud, and the cement pond must be dealkalized, disinfected and fertilized before being put into breeding. Generally, 2 jin of seedlings of "Agricultural Science 10" are put per square meter, and more than 14 jin of finished Loach can be produced in 90-120 days, which is a new and efficient model for the development of intensive breeding in factories.

The model of cultivating Loach in cage

The breeding site should choose the lake, the shallow water near the reservoir or the living water pond, the water quality is good, and there is no industrial pollution, the size of the cage can be large or small, the small area is 1-2m2, the large one is 20---40m2, and generally 10--20m2 is appropriate. The bottom of the net should fall into the bottom of the pool, the bottom of the net should be covered with 8-10 cm of fat mud, and the cage should be more than 40 cm above the water surface to prevent Loach from jumping and escaping. Under the condition of sufficient bait and good water quality, the seedlings of "Nongke 10" are put into 1.5 jin per square meter for 90-120 days, and the finished Loach can be produced more than 10 jin per square meter, which is another efficient model for cultivating Loach.

The box body is made of polyethylene woven mesh, the mesh 0.5-1.0cm, the net height depends on the aquaculture water body, but the upper half of the cage must be higher than 40cm above the water surface to prevent Loach from escaping, the bottom of the box should be covered with 20cm thick manure and soil, and the top layer is soil. The stocking amount of Loach species in cages should be determined according to the conditions of the water body, and more water, fertilizer and water can be released, otherwise less should be released. Artificial feeding is the main way to cultivate Loach in cage. A 2m2 feeding table should be set up in the cage. The table is 20-25cm from the bottom of the pond, and the bait should be put on the table during feeding. Artificial bait can be fed with pellet feed made of bran, silkworm pupa and earthworm or hard pellet feed. Animal protein should account for more than 50% of artificial formula feed. The daily feeding amount is 3% Murray 5% of the body weight of Loach, which is fed three times in the morning, in the middle and in the evening. Usually, you should scrub the net clothes frequently, maintain the permeability of the water body inside and outside the cage, and make enough bait creatures enter the box. At the same time, you should often check the net clothes and repair them immediately if there are any loopholes.

The way of raising Loach in Paddy Field

The way of raising Loach in rice field is to make full use of the water source of rice field, natural bait and weeds in the field, which can effectively reduce the feeding of bait and reduce the breeding cost. Raising Misgurnus anguillicaudatus in rice field can promote the yield of rice, but the varieties planted in rice are required to have strong fertilizer resistance, hard panicle stem and not easy to be crooked. Loach culture in rice fields needs to dig a loach ditch with a width of 1-1.5 meters and a depth of 0.3-0.5 meters along the inside of the ridge, which is easy to catch. The soil collected from Loach ditch is used to heighten and widen the ridge of the field and control the water level. The seedling of "Agricultural Science 10" is 180,200jin per mu, and the finished product of Loach is about 1400 jin per mu, which is a breeding model with development prospect.
