How to breed loach

Around the pond where loach is cultured, the water level should be 40 cm higher, the slope should be 60℃~70℃, the water depth should be 80~ 100 cm and the water depth should be 30~50 cm. Net, plastic plate or porcelain plate should be used as fence around the pond to prevent snakes, mice and other enemies from entering the culture area. In addition, the water inlet and outlet are wrapped with 120 mesh net cloth to prevent loach from escaping, pests, wild fish eggs and fry from entering the pond.

2. Preparation before stocking

It is necessary to clean the pond before releasing loach. When the water depth reaches 10cm, it is necessary to use quicklime as mud, and then spray water to disinfect the whole pond. Apply base fertilizer three days before stocking.

3. sow seeds.

Loach seedlings comes to the pond in May every year, and the planting density is 1500-2000 plants /m2. In the process of fry production, attention should be paid to the water quality test before stocking to check whether the toxicity of water body is eliminated.

4. Feeding management

When the body length of loach seedlings is less than 2cm, topdressing can be appropriate according to the water conditions. Topdressing can use farmyard manure fermented by pig, cow, chicken and human manure, and sprinkle it once in the morning and evening. When the loach grows to 2cm, deepen the water level to 50cm, fertilize the water, and feed it once in the morning and once in the evening. The water quality of loach culture is very important. In addition to changing the water once or twice a week, we should also apply fertilizer frequently to keep the water yellow-green.
