Key points of artificial culture technology of loach

First, raise Loach in a special pond

It is generally a culture method adopted by producers who specialize in the cultivation of Loach.

1. The construction of the breeding pond: choose the place with good light, warm ventilation, convenient transportation, adequate water source, convenient entry and drainage, and no pollution source within 3 kilometers to build the breeding pond. The soil of Loach pond is neutral or slightly acidic clayey soil. The area is 100-300 square meters, the pool depth is 80-100 cm, and the water depth is 30-50 cm.

2. Pond cleaning disinfection: Loach species were disinfected with quicklime 15 days before stocking. Keep the pool water 10 cm deep and sprinkle it with 100 grams of quicklime water per square meter.

3. Laying base fertilizer: mainly using organic fertilizer to cultivate a large number of zooplankton as bait for Loach. After the release of seedlings, gradually strengthen the feed feeding, and topdressing organic fertilizer.

4. Feed: Misgurnus anguillicaudatus has miscellaneous food habits. Small animals, plants, microorganisms and organic detritus in the water are all its favorite foods. Artificial feeding should also be fed with maggots, earthworms, small miscellaneous fish meat, clam meat, fish meal, livestock and poultry scraps and other animal feed and plant feed such as wheat bran, rice bran, soybean dregs, cake and so on.

5. regular, fixed-point, qualitative and quantitative feeding: the amount of feeding depends on the water quality, weather and food intake, once in the morning, in the middle and in the evening when the water temperature is suitable, and once in the morning and afternoon when the water temperature is low. Percentage of body weight of Loach fed in the pond: March, 1-2%, April-June, 3-5%, July-August, 10-15%; September, 4%. The proportion of plant feed and animal feed under different water temperature conditions: less or no input when the water temperature is lower than 10 ℃ or higher than 30 ℃; water temperature 11-20 ℃, plant feed 60-70%, animal feed 30-40%; water temperature 21-23 ℃, plant feed and animal feed 50% each; water temperature 24-29 ℃, plant feed 30-40%, animal feed 60-70%.

6. Water quality management: after releasing Misgurnus anguillicaudatus, fertilizing and cultivating plankton are timely according to the fat and thin water quality, so that the water body is always in a living and refreshing 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. It is found that Loach often swims to the surface to swallow air, indicating that there is a lack of oxygen in the water, so fertilizer should be stopped and new water should be injected immediately. There is no feeding from December to February of the following year, just increase the depth of the pool and put pig and cow dung in the corner of the pool to raise the water temperature and ensure the Loach to survive the winter safely.

Daily management: patrol the pond once every morning and evening to check the activities, eating and diseases of Loach, at the same time, observe whether there is water leakage in the culture pond, whether the Loach escapes or not, and the cement pond should remove the residual feed every day and make daily records.

Raising Loach in Paddy Field

When Loach is stocked in rice fields, better economic benefits can be obtained by using natural bait organisms such as earthworms, Chironomus larvae, water fleas and weeds. Because of its strong vitality, Loach can drill into the wet mud and breathe through the intestines and skin to maintain its life even when the rice fields are exposed to water. So Misgurnus anguillicaudatus is one of the ideal objects for rice field culture. The construction of rice fields is the same as raising other fish, digging one or more fish slips in the fields, covering an area of 2-3 square meters and a depth of about 50 centimeters. The fish slips are connected with the fish ditches, and the fish ditches are opened into the word "field" or "well". Fish-blocking facilities should be set up at all entrances and exits to prevent escape. There are 1.5-20,000 Loach seedlings with a length of about 3 cm per mu of rice field. Pay attention to avoid the use of lime and pesticides, properly bait and fertilize, catch after rice harvest in autumn, or continue to breed by irrigation, and then catch them on the market when ploughing the fields in the spring of the following year.

In addition, in the water surface of lotus root, Zizania caduciflora and other aquatic plants, a certain amount of Loach can be released. Generally, there are about a thousand tails per mu, as long as the feeding and management is proper, the water surface income can be increased.

Third, raising Loach at home

That is, the use of the front and back of the house or vegetable garden pit and reservoir to raise Loach. Generally, it can be put into 4000-5000 young seedlings with a length of 3-4 cm per mu, and it can also be mixed with yellow food and carp. Usually pay attention to feeding and fertilization, such as leftover meals, livestock and poultry dung, vegetable leaves, etc., feed should be used in combination with plant and animal. At the same time, the water quality should be well controlled. when the Loach is found to swallow air out of the water surface, it indicates that there is a lack of oxygen in the water body, so fertilizer should be stopped and new water should be replaced. Loach individuals can be caught and listed when they grow to 15-20 cm. After 8-10 months of feeding, the yield per mu can reach more than 100 kg.
