1. Build a pool: in front of the house and behind the house, around the courtyard, choose a place with water, shelter from the wind and sun to build a pool. The pool is generally of masonry structure, and its depth is about 1 m. After the pool is built, it should be leveled with cement, dried and then put into the mud. 5 feet, inject clean water 1 foot, and you can put the seeds.

2. Seed sowing: After the pool is built, put 1- 1 per square meter. Five catties counts as loach seedlings. Seedlings can be purchased in the market or propagated and captured by themselves; In any case, we should choose a robust and harmless loach seedlings with uniform size, and match it according to the proportion of three females and one male. The method of male and female identification can be observed by its appearance: male head tip, narrow and long pectoral fin, body thickness as tail end, and bone piece at the base of tail tip fin; The female's head is oval and flat. Female loach has strong oviposition ability. A female loach can lay more than 4000 eggs from early summer to early autumn, usually 2-3 times a year, laying more than 4000 eggs 10000.

3. Feeding: Since Misgurnus anguillicaudatus is an omnivorous fish, cow dung, rice bran, wheat and fly maggots can be used as feeding bait, generally three times a day. The feeding amount is generally determined according to the feeding situation.

4. Fertilization: In the process of loach feeding, some organic fertilizers can be supplemented appropriately, but the fertilization must not be too frequent, and the pool water should be changed frequently, usually once every 10- 15 days. 5. Catch: To catch loach, first of all, we should drain the water in the pond, and adopt the method of catching large and letting small to ensure that there is a certain amount of loach seedlings in the pond, which is conducive to secondary culture and high yield.

5. Note: Misgurnus anguillicaudatus and Monopterus albus should not be mixed in a pool, because Monopterus albus will swallow Misgurnus anguillicaudatus. Loach is put in the eel pond to prevent the eels from intertwining. The side wall of the pool must be about 1.5 feet above the water level, because the loach is active to prevent it from escaping. Urban residents and families who can't afford to build ponds can also feed them in pots and jars. "Summer solstice" is the best time for breeding and planting, so we should hurry to sow.
