Loach breeding technology, how to raise loach, loach price, loach breeding base

The aquaculture pond is built in a place with good light, warm ventilation, convenient transportation, sufficient water, convenient water supply and drainage, and no pollution sources within 3 kilometers. The loach pond soil is neutral or slightly acidic clay. Area100 ~ 300m2, pool depth 80 ~100cm, water depth 30 ~ 50cm.

Disinfect the pond with quicklime 15 days before stocking loach species. The pool water 10 cm deep, and the whole pool is sprinkled with quicklime100g per square meter.

Before stocking loach, disinfect it with 3% saline bath 10 minute. Choose 50 ~ 60 loach varieties with a body length of 3 ~ 4 cm per square meter at noon on sunny days.

Feed-fed loach has a variety of eating habits, and small animals, plants, microorganisms and organic debris in the water are all its favorite foods. Artificial feeding should also be fed with animal feed such as maggots, earthworms, small miscellaneous fish, mussels, fish meal, livestock and poultry leftovers, and plant feed such as wheat bran, rice bran, bean dregs and cake meal.

Regular, fixed-point, qualitative and quantitative feeding. The feeding amount depends on water quality, weather and feeding conditions. When the water temperature is suitable, feed it once a day in the morning, at noon and at night, and once a day in the morning and evening when the water temperature is low. The percentage of feeding amount to the body weight of pond loach: March1%~ 2%; From April to June, 3% to 5%; July-August10% ~15%; In September, 4%. The feeding ratio of plant feed to animal feed at different water temperatures: when the water temperature is lower than 10℃ or higher than 30℃, feed less or not; Water temperature 1 1 ~ 20℃, plant feed accounts for 60% ~ 70%, and animal feed accounts for 30% ~ 40%. The water temperature is 2 1 ~ 23℃, and the plant feed and animal feed account for 50% respectively. The water temperature is 24 ~ 29℃, plant feed accounts for 30% ~ 40%, and animal feed accounts for 60% ~ 70%.

Water quality management After loach stocking, topdressing should be done in time according to the fatness and thinness of water quality, and plankton should be cultivated to keep the water fresh and cool all the time. When the water temperature reaches 30℃, replace fresh 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 and swallows, indicating that there is no oxygen in the water, so fertilization should be stopped and fresh water should be injected immediately. During the wintering period, it is not necessary to feed loach from 65438+February to February of the following year. It is only necessary to increase the depth of the pond, put pig manure in the corner of the pond, raise the water temperature, and ensure the safe wintering of loach.

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 leakage in the culture pond and whether the loach escapes. The cement pool should remove the residual feed every day, and make daily records.

Artificial feeding of loach

Category: Other practical technologies/aquaculture Scope of application: not limited

(1) Special pond for raising loach. Generally, it is a farming method adopted by producers specializing in loach farming. The bottom of the pond should be mud. If it is a cement pool, mud with a depth of 15-20cm should be paved. The pond area should not be too large, and about one acre is appropriate. Each acre can accommodate 50,000-65,438 thousand+seedlings with a plant length of 3-4 cm. Before releasing seedlings, base fertilizer should be applied, mainly organic fertilizer, and a large number of zooplankton should be cultivated as bait for trowels. After releasing seedlings, feed and organic fertilizer should be gradually strengthened. Feed types mainly include rice bran, bean cake, bran, bean dregs, silkworm pupa powder, earthworm, food processing waste and so on. Fertilizers include human livestock manure, crop straw compost and so on. If the water temperature is higher than 30℃ or lower than 10℃, the feed rate should be reduced. Generally, it can be caught in August 8- 10/0, and the high yield can reach 250-400 kg per mu. The length of each tail is about 15cm, and the weight is 10- 15g, which meets the commodity specifications.

(2) Raising loach in paddy field. When feeding Misgurnus anguillicaudatus in paddy field, natural food organisms such as earthworm, chironomid larva, Daphnia, weeds and so on can be used, and a small amount of feed can be fed, which can obtain good economic benefits. Because of its strong vitality, loach can get into wet mud even when basking in the sun in rice fields, and maintain its life through intestinal tract and skin breathing. Therefore, the trowel is one of the ideal objects for rice cultivation. In the construction of rice fields, like raising other fish, one or several fish slips are dug in the field, with an area of 2-3 square meters and a depth of about 50 cm. The fish chute is connected with a fish ditch, which is shaped like a field or a well. Fishing facilities should be set at the entrance and exit to prevent escape. Loach seedlings 15000-20000 with a body length of about 3 cm per mu of paddy field. Pay attention to avoid using lime and pesticides, feed and fertilize properly, and catch the rice harvested in autumn, or continue to irrigate and breed, and then catch it in the next spring. Generally, 30-50 kg loach can be harvested per mu of rice field.

In addition, a certain amount of loach can also be stocked on the water surface of aquatic plants such as lotus root, lotus planting and water bamboo. Generally, there are about 1000 tails per mu. As long as the feeding management is proper, the apparent income can be improved.

(3) Loach is domesticated. That is, loach culture is carried out by using pits and reservoirs in front of the house or behind the vegetable garden. Generally, 4000-5000 seedlings with a length of 3-4 cm can be stocked per mu, or mixed with yellow rice and carp. Usually pay attention to feeding and fertilization, such as leftovers, livestock manure, vegetable leaves and so on. And the feed should be used with plants and animals. At the same time, we must control the water quality. When loach is found to be "swallowed" out of the water, it means that the water body is short of oxygen, so fertilization should be stopped and fresh water should be replaced. The loach can be caught and marketed when it grows to 15-20 cm. After 8- 10 months of feeding, the yield per mu can reach more than 100 kg.
