It is not difficult to raise loach. What is the cost of an acre of land?
Matters needing attention in loach culture:
1. The time for raising loach seedlings in the pond is May every year, and the density of raising loach seedlings is 0/500 to 2,000 per square meter. When the loach is raised to a body length of 3 cm, it should be screened and divided into pools, and the density of loach larvae is 60 to 80 per square meter. In the process of seeding, we should pay attention to the water test before stocking and check whether the toxicity of water body is eliminated.
2. Change the water 1 ~ 2 times a week, and apply fertilizer frequently to keep the water color of the pond "fat, lively, tender and cool" and yellow-green.
3. Patrol the pond 1 time in the morning, noon and evening, observe the activity of loach and the change of water color, and handle the problems in time when found.
4. Prevent diseases on a regular basis, often clean the bait table, disinfect the feed table and tools, and regularly administer drugs to prevent fish diseases.
5, pay attention to prevent enemy invasion and loach escape, often check the inlet, outlet and pond ridge.

Preparation before stocking loach:
1, requirements for pond construction:
The loach pond needs an area of 5 mu to 10 mu, the water depth of the pond needs to be 1.5 m to 1.8 m, the sludge at the bottom of the pond has a neutral ph value, the wall of the pond should be compacted, subject to water tightness, the pond is convenient to enter and exit water, the surrounding of the farm should be quiet, and the water quality is pollution-free. Each acre of pond should be equipped with 1 aerator, and a rat net should be set around the pond.
2. Clean the pond:
Before the release of loach seedlings in early spring, the pond should be cleaned with quicklime 20 days in advance, and then the water quality should be improved with oxygen-increasing particles and double salt. After cleaning the pond and adding water again, plant some water spinach, lotus root, water bamboo, water hyacinth and water peanut in the pond, which will help improve the water quality and avoid the exposure of loach.
