1. Build the pool: In the back of the house, around the courtyard, choose a place where there is water and shelter from the sun. The pool is generally made of brick and stone, and the pool depth is about 1 meter. After the tank is laid, wipe it with cement, put it into the mud about 17 centimeters when it is dry, and inject 33 centimeters of clean water to put the seedlings.
2, put seed: according to 500-750 grams of water per square meter calculated to put seedlings. Seedlings can be purchased on the market or propagated and captured by themselves. It is necessary to choose seedlings that are unblemished and uniform in size, and be placed in a ratio of one male and three females. (male and female identification method: male's head, narrow pectoral fins, the body is as thick as the tail, the tip of the tail is upturned, the base of the ray has a thin slice of bone; the female body is conical, the former is thick and the tail is thin, the pectoral fin is wide But short, the end is round and flat.) The female otter has extremely strong spawning power, and a female otter usually produces eggs 2-3 times a year, spawning about ten thousand eggs.
3, feeding: As loach is omnivorous fish, so cow dung, rice bran, wheat bran, fly maggots can be fed as food, generally three times a day can vote, according to feed intake determined.
4, fertilization. During the breeding process, some organic fertilizers may be properly added, but the fertilization can not be too frequent, and it is necessary to change the water frequently, and generally change the water once every 10-15 days.
5, capture: first put the pool water to dry, take a large catch and stay small method to ensure that the pool has a certain number of seedlings.
Matters needing attention: (1) The loach and jaundice should not be polyculture, because the cricket will eat mud. (2) The edge of the pool must be about 0.5 meters above the water surface. The inlet and outlet of the pool should be blocked by barbed wire to prevent the mud from fleeing. (3) When the temperature of the early winter drops to 5-10°C, the loach stops feeding, enters the mud and hibernate, and waits until the water temperature rises in the next year and then moves out of the cave. In order to keep the pool water at an appropriate temperature, besides changing the water in summer, shelters should be erected on the pool, and plastic beveled greenhouses should be set up in winter to increase the temperature inside the pool. (4) Loach is a fish with high fecundity and fertility, and it has a fast growth rate. It takes only about 120 days from spawning to 150 grams of commercial loquats, so management must be strengthened. (5) Households without conditions to build pools can use cylinders and pots for feeding. (6) The "summer solstice" is the best period for seedlings to be planted. It is necessary to seize the opportunity to plant seedlings to achieve better results.

Loach is a warm-water fish, living in the 15-30 °C environment, the most suitable temperature is 24-27 °C. Farmers build ponds to save mud, invest less, benefit faster, and save labor, which is a good way to get rich. Let's talk about my breeding method.
