1. How to raise loaches well?

Loach is not only a delicacy on people's tables, it has tender meat, delicious taste, rich nutrition, and high medicinal value. Loach has a fixed consumer group in both domestic and foreign markets and is a special aquaculture variety that is deeply loved by consumers. With the development of special aquaculture and the needs of domestic and foreign markets, loach farming has attracted people's attention, and loach farming has also become an important way for farmers to make a fortune. Here we introduce how to raise loach with good benefits, low risks, high survival rate, easy to raise and catch, and few diseases.

1. Pond construction: The pond should be close to the water source, with an area of ​​200-400 square meters and a water depth of 0.7-1 meter. The pond wall should be built with bricks and stones, or pounded with cement, and the bottom of the pond should be compacted. It should be strong, durable and leakproof. The inlet and outlet should be blocked with wire or plastic nets. The bottom of the pond should be tilted towards the drain for drainage and fishing. Leave 10 cm of water, and use 50 kg of quicklime and 15 kg of bleaching powder per mu to clean and disinfect the pond.

2. It is best to choose loaches with strong physique, normal body color, correct body shape, no injuries and strong vitality for stocking. After cleaning and disinfecting the pond for 7 days, fill it with water to a depth of 20-30 cm. Apply enough basal fertilizer on the sunny side of the pond and deepen the water to 40-50 cm. After 3 days, stock loaches, 100-150 loaches with a body length of 3-5 cm per square meter of water surface, or 60-70 loaches with a body length of more than 6 cm.

3. Feeding: Set up a feeding table for feeding at a fixed point. Generally, feed once in the morning and afternoon every day. The daily feeding amount is 5%-8% of the body weight of the loach in the pond. The specific feeding amount depends on the water quality, weather, and loach feeding situation. Do not feed when the water temperature is too high or on thunderstorm days.

4. Water quality regulation: Fertilize according to the fertility of the pond water. The transparency of the pond water should be controlled at 15-20 cm, and the water color should be yellow-green. When the water temperature exceeds 30℃, loaches will burrow into the mud to avoid the heat, which may cause suffocation and death due to lack of oxygen. At this time, new water should be added frequently to adjust the water temperature and increase the dissolved oxygen content in the water body. At the same time, sunshade measures should be taken. Water hyacinth and duckweed can be used for sunshade. When loaches swim to the surface of the water and "swallow air", it means that there is a lack of oxygen in the water. Fertilization should be stopped and new water should be added in time. In winter, the water level should be deepened and the water temperature should be increased to ensure the safety of loaches in winter.

5. Prevention of diseases and pests: Disinfect regularly and do a good job of "three disinfections", i.e., disinfection of loach bodies, ponds and food tables. Remove dead loaches immediately to prevent infection of other loaches and treat them promptly. Remove weeds around the pond to keep the breeding environment clean, prevent frogs from invading, catch frogs in time and remove frog eggs; block the water inlet with a silk screen to prevent wild fish from entering the pond with water; and drive away birds in time.

Loach breeding technology is simple to learn, easy to manage, low investment, high yield, significant benefits, and fast capital recovery. It is a good project suitable for farmers.

(1) Raising loaches in special ponds. This is a breeding method generally adopted by producers who specialize in loach breeding. It is best to have a mud bottom in the pond. If it is a cement pond, the soil should be 15-20 cm deep. The area of ​​the pond should not be too large, about one mu is appropriate, and 50,000 to 100,000 young seedlings 3-4 cm long can be placed per mu. Before stocking the seedlings, base fertilizer should be spread, mainly organic fertilizer, to cultivate a large number of zooplankton as bait for loach. After stocking the seedlings, gradually increase the feeding of feed and apply organic fertilizer. The main types of bait fed include rice bran, bean cake, bran, bean dregs, silkworm pupa powder, earthworms and food processing waste. Fertilizers include human and livestock manure, crop straw compost, etc. If the water temperature is higher than 30℃ or lower than 10℃, the amount of feed should be reduced. Generally, it can be caught after 8-10 months of breeding, and the high yield can reach 250-400 kg per mu. Each tail is about 15 cm long and weighs 10-15 grams, meeting commercial specifications.

(2) Raising loaches in rice fields. Raising loaches in rice fields can use natural bait organisms such as earthworms, chironomid larvae, water fleas and weeds in the fields. By feeding a small amount of feed, good economic benefits can be achieved. Because loaches are strong in vitality, they can burrow into wet mud and use their intestines and skin to breathe to maintain their lives even when the rice fields are drained and dried. Therefore, loaches are one of the ideal objects for rice field farming. The construction of rice fields is the same as raising other fish. One or more fish ponds are dug in the fields, with an area of ​​2-3 square meters and a depth of about 50 cm. The fish ponds are connected to the fish ditches, and the fish ditches are opened in the shape of a "field" or "well". Fish interception facilities should be set up at the inlets and outlets to prevent escape. 15,000 to 20,000 loach fry about 3 cm long are released per mu of rice field. Be careful to avoid using lime and pesticides, feed and fertilize appropriately, and catch them after the rice harvest in autumn, or continue to raise them after flooding. They can be caught and put on the market when the fields are plowed in the spring of the following year. Generally, 30-50 kilograms of loaches can be harvested from every acre of rice field.

In addition, a certain number of loaches can be raised in the water surface where lotus roots, lotus, wild rice stems and other aquatic plants are planted. Generally, about 1,000 loaches are raised per mu. As long as the breeding and management are proper, the income from the water surface can be increased.

(3) Raising loaches at home. This means raising loaches in pits and reservoirs in front of and behind houses or in vegetable gardens. Generally, 4,000 to 5,000 young fish 3 to 4 cm long can be released per mu. They can also be mixed with yellow mullet and carp. Pay attention to feeding and fertilizing at ordinary times, such as leftovers, livestock and poultry manure, vegetable leaves, etc. Feeds should be a combination of plant and animal. At the same time, control the water quality. When loaches are found to jump out of the water to "swallow air", it means that there is a lack of oxygen in the water body. Fertilization should be stopped and new water should be replaced. When loaches grow to 15 to 20 cm, they can be caught and put on the market. After 8 to 10 months of breeding, the yield per mu can reach more than 100 kg.

3. How to breed loach?

What the above person said is a bit wrong. Loaches cannot be raised together with eels. Eels eat loaches. There is a video online, which is very detailed. I wish you success in breeding.

4. How to raise loach well

Loach can be cultured from March to October. Loach has low requirements for water bodies and can be fully utilized in small ponds, shallow ponds, ditches, wild rice fields and other water bodies. The stocking density is generally 40 to 50 loaches per square meter of water surface. Before the loach is released, the pond should be cleaned and disinfected, and the loach seeds should be disinfected with drugs. Before the fish pond is filled with water, sufficient basal fertilizer should be applied to cultivate aquatic plankton for supplementary feed. The suitable temperature for loach growth is 10 to 30℃, and the optimal temperature is 25 to 27℃. When the water temperature exceeds 30℃ in summer or is lower than 5℃ in winter, loach will dive into the soil to spend the summer and winter. The loach can be fed 3 days after the loach is released. Loach is an omnivorous fish. When feeding, attention should be paid to the reasonable combination of animal and plant feeds, and flexible control should be made according to different seasons, water temperatures, natural feeds and eating conditions.
