Generally, loach yields more than 2,000 Jin per mu. Calculated by 2,000 Jin, the market price is calculated by the current average wholesale price 1 1 yuan, and the income is 22,000 yuan. After deducting the total cost of breeding, an acre of loach can earn 7900 yuan. The breeding period of inch loach seedlings is about 100 days, and most parts of the country can be cultured for two seasons a year, so raising an acre of loach can earn 15800 yuan a year. At the same time, with the continuous improvement of farmers' breeding technology, there are more and more people who breed by themselves or buy splash seedlings, and the investment in cultivating splash seedlings of loach will be less, and the breeding efficiency will be higher.

1, benefit analysis of cement pool: the construction cost of a cement pool of 10 square meter is 300-400 yuan, and seedlings can be put in 30 kg. The purchase of 1 kg loach seedlings 9-10 yuan, Misgurnus anguillicaudatus Miao' an10 yuan is 30 kg×/kloc. Self-preparation of feed: the feeding cost of loach is 1. 1 yuan for each kilogram of weight gain. After four months of feeding, we calculate it by four times. The feeding cost is 396 yuan in 4.4 yuan, the medicine 15 yuan, and the total investment of a cement pool 10 square meter. It can produce loach 120 kg, the output value 1440 yuan in just four months, and the annual net profit: (1440 yuan (output value) -300 yuan (seedling) -396 yuan (feeding cost)-15 yuan (medicine) =729 yuan net profit). 50 ponds can be built per mu 10 square meter, and the annual output of loach per mu can reach 6,000 Jin, with a price of 12 yuan per Jin and an output value of 72,000 yuan. After deducting the cost, the profit per mu is more than 36,000 yuan.

2, loach is not difficult to breed, but the key is to learn the technology well. It is said that Hunan Huaihua Xinmin Ecological Breeding Co., Ltd. is mainly engaged in breeding Monopterus albus, Misgurnus anguillicaudatus, four major fishes, raising pigs, raising chickens, earthworms and Tenebrio molitor, and providing high-quality Pennisetum species to the outside world. The company conducts ecological breeding technical training for the whole country.

3. The investment cost for cage culture of loach is 25,750 yuan. The specific cost depends on the cost of a cage first: a cage 60 yuan; Need to buy 20 kg of wild loach, counting 200 yuan; After feeding for 4-6 months, the weight gain is 4-6 times, reaching at least 80 kg. Every kg of weight gain costs 4 yuan feed, and the total feed cost is 240 yuan. If a large number of self-bred earthworms are used as feed, the cost can be reduced by 20%. Drug cost 15 yuan; * * * above is 5 15 yuan.
