How many jin of Loach can be raised on one mu of land? Which breeding points should farmers pay attention to?

Misgurnus anguillicaudatus, known as "ginseng in the water", is a kind of aquaculture in the north and south of China. Although it looks like a snake, it still tastes delicious. Now Loach artificial culture is relatively common, that mu of land can raise how many jin of Loach? Which breeding points should farmers pay attention to?

How many jin of Loach can be raised on one mu of land?

It is understood that about one mu, each mu can put 50, 000-100000 young seedlings with a length of 4 centimeters. Before seedling release, base fertilizer should be applied, mainly organic fertilizer, and a large number of zooplankton should be cultivated as bait for mud spades. After the release of seedlings, gradually strengthen feed feeding, and topdressing organic fertilizer, the main kinds of bait are rice bran, bean cake, wheat bran, bean dregs, silkworm pupa powder, earthworms and food processing wastes. Fertilizers include human and animal manure, crop straw compost and so on. If the water temperature is higher than 30 ℃ or lower than 10 ℃, the feeding amount should be reduced. Generally, 8MUE can be captured in 10 months, and the high yield can reach 250MUR 400kg per mu. The length of each tail is about 15 cm, and the weight is 10ml 15g to meet the commodity specification.

First, which breeding Loach should farmers pay attention to?

1. Seed release and water quality control

Each mu is put into neat specifications, smooth body surface, disease-free and deformity-free. 280,300kg of Loach seedlings per kilogram. Before stocking, soak and sterilize for 15 minutes with 3%-4% salt water at a water temperature of 10-15 ℃.

When the Loach species first entered the pond, the water depth was maintained at 10-20 cm. Later, with the growth of the Loach species, the water level gradually deepened to its proper depth, which was shallower at ordinary times and deepened when it was hot and hot, and new water was often injected to maintain a good water environment. When the weather is muggy, the pool water is easy to lack oxygen. If you find Loach swimming to the surface to eat air, you should add new water or take measures to increase oxygen in time.

2. Soil quality of pond

The soil quality has a great influence on the effect of raising Loach. The production practice shows that the Loach growing in clay soil has yellow body, more fat, soft and tender bones and delicious taste, while Loach growing in sandy soil has black body, less fat, hard bones and bad taste.

3. Feed selection

Misgurnus anguillicaudatus is an omnivorous small fish with a wide range of feed sources. Water fleas, earthworms and fly maggots are natural food organisms of Loach, which can be fed with rice bran, bean cake, bean dregs, blood meal, wheat bran and so on. The food intake of Misgurnus anguillicaudatus is closely related to the water temperature. The daily feeding is 1% of the total body weight of Loach in March, 4% of the total body weight of Loach from April to June, 1% of the total body weight of Loach from July to August, and 4% of the total body weight of Loach from September to October.

4. Feeding skills

Loach was raised in the pond, and the Loach seedlings were not fed within 2 days after the Loach seedlings were put into the pond, and then fed after the Loach seedlings adapted to the pond. To achieve timing, quantitative, qualitative, positioning.

When feeding Misgurnus anguillicaudatus in the process of feeding Loach, the actual feeding amount can be judged by observing the surface phenomenon of the pond. First, look at the length of time to eat, second, look at the growth size of Loach individuals, third, look at the movement of the water surface, and fourth, look at the changes of water quality.
