1, rearing pool construction

Select good light, warm and ventilated, convenient transportation, adequate water supply, easy access to water, no pollution sources within 3 kilometers of the place to build rearing pool. Loach pond soil for neutral or slightly acidic clay soil. Area 100 to 300 square meters, pool depth 80 to 100 cm, water depth 30 to 50 cm.

2, clear pool disinfection

Lime pool disinfection 15 days before loach seed stocking. Leave the pool water 10 cm deep, with 100 grams of quicklime per square meter of water sprinkled throughout the pool.

3, seedling stocking

Loach seed stocking with 3% salt water bath disinfection for 10 minutes before stocking. Choose a sunny day at noon to put each square meter of 3 ~ 4 cm loach species 50 ~ 60.

4, feed feeding

The loach is omnivorous, small animals, plants, microorganisms and organic debris in the water are its favorite food. Artificial feeding should also be fed maggots, earthworms, small fish, mussels, fish meal, livestock and poultry scraps and other animal feed and bran, rice bran, soybean residue, cake meal and other plant feed. Fixed time, fixed point, fixed quality, fixed quantity feeding. The feeding quantity depends on the water quality, weather and feeding condition, and the water temperature is suitable for feeding once a day in the morning, noon and night, and once a day in the morning and afternoon when the water temperature is low. Feeding amount as a percentage of the weight of loach in the pool: March, 1% to 2%; April to June, 3% to 5%; July to August, 10% to 15%; September, 4%. Feeding ratio of plant feed and animal feed under different water temperature conditions: when the water temperature is lower than 10℃ or higher than 30℃, less or no feeding; when the water temperature is 11～20℃, the plant feed accounts for 60%～70%, and the animal feed accounts for 30%～40%; when the water temperature is 21～23℃, the plant feed and the animal feed each accounts for 50%; when the water temperature is 24～29℃, the plant feed accounts for 30%～40%, and the animal feed accounts for 60%～70%. Animal feed accounted for 60% to 70%.

5, water quality management

After loach stocking, according to the water quality of fat and thin situation of timely fertilization, cultivation of plankton, so that the water body is always in a live, cool state. When the water temperature reaches 30℃, replace the new water in time and increase the depth to reduce the water temperature and prevent floating head. When loaches are found to swim to the surface of the water to swallow air from time to time, it indicates that the water lacks oxygen, so fertilization should be stopped and new water should be injected immediately. In the wintering season, from December to February, you can not feed, just increase the depth of the pool water, and put pig and cow dung in the corner of the pool to improve the water temperature to ensure the safety of loach wintering.

6, daily management

Pool patrol every morning and evening, check the activities of loach, feeding, disease and other conditions, at the same time, observe the breeding pool with or without water seepage and leakage, loach with or without escape phenomenon, the cement pool should be cleared every day to remove the residual feed, and do a good job of daily records.
