What should be paid attention to in cage culture of Loach

I. site selection

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.

II. Cage setting

The size of the cage can be large or small, the small area is 1mi 2m ², the large one is 20m ², generally 10Mel 20m ²is suitable. The box body is made of polyethylene woven mesh, mesh 0.5-1.ocm, 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 escape, the bottom of the box should be covered with 20cm thick manure and soil, and the top layer is soil.

III. Loach species stocking

The stocking amount of Loach species in the cage should be determined according to the conditions of the water body, and the amount of water, fertilizer and water can be released more, otherwise it should be released less. Generally, there are 1 200 species of Loach species 900 6cm per m ².

IV. Feeding and management

Artificial feeding is the main way to cultivate Loach in cage. A 2m ²feeding platform should be set up in the cage, which is 20-25cm away from the bottom of the pond. Artificial bait can be fed with pellet feed made of bran, silkworm pupa and worm 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.

V. Daily management

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. In addition, it is also necessary to prevent pollution and enemy biological attacks such as pesticides and chemical fertilizers.

VI. Disease prevention and control

Usually to do a good job in the prevention and control of fish diseases, bait should adhere to the "four" principle, timely removal of residual bait on the table, regularly sprinkle with quicklime or hang bags with bleach. Bleach hanging bag method: wrap modi powder around the table with two layers of gauze and hang 3 bags at a time, which can effectively prevent the occurrence of diseases.
