1. To build a tank for yellow locust and muddy aquaculture ponds to raise yellow leeches and muddy leeches. To choose sheltered areas where the winds are sunny, the environment is quiet, and the water sources are convenient, cement pools and earthen ponds can be used. Reservoirs can also be used in reservoirs, ponds, gutters, and rivers. Box culture. The area is generally 20 square meters to 100 square meters, too big to manage. If the cement pond is used to raise yellow peony roots and mud lice, it must be dealt with alkali before putting on seedlings. If using earthen ponds to raise leeches and mud lice, it is required that the soil is hard and the bottom of the pond should be compacted. The shape of the rearing pond is determined by the topography. The square can be round and round. The depth of the pool is 0.7 meters to 1 meter. Whether it is a cement pond or an earth pond, it must be filled with a mud layer at the bottom of the pond and be 30 centimeters thick. Fertilizers with a lot of organic matter are good, and it is beneficial to digging and burrowing in yellow locusts and loach. When constructing the pool, pay attention to installing the fishing nets and the overflow fishing nets in order to prevent the yellow locusts and mud lice from fleeing. About 10 days before the seedlings were completely disinfected with quicklime, and the water was drained 3 to 4 days before the emergence of the shoots, and fresh water was injected.
Second, choose a good yellow trout, loach seedlings breeding yellow trout and loach success or not, seedlings is the key. The seedlings of Astragalus are best cultivated artificially by domesticated deep yellow or large golden spotted nymphs, and can not use variegated seedlings or domesticated seedlings. The seedling size of Scutellaria baicalensis should be 50 to 80 per kilogram, which is too small for poor feeding power and low survival rate. The stocking density is generally 1 kg to 1.5 kg per square meter. After 20 days of stocking, the Astragalus membranaceus will be placed at the ratio of 1:10 to the loach seedlings. Loach seedlings are best cultivated artificially because of the high survival rate of artificial breeding.
Third, feed the compound feed First install the feed table, feed table with a plastic or plastic board will do, the area according to the size of the pool, lower than the water surface 5 cm. The first 3 days after the release of Astragalus seedlings, do not feed, let the Astragalus fit the environment, and start feeding on the 4th day. It is best to feed the feed at around 7:00 pm every day. At this time, the feed intake of Scutellaria baicalensis is the highest. Artificial rearing of jaundice is mainly based on feed, and some pupa, locust, and mealworm are properly fed. Artificially domesticated yellow quail, compound feed and earthworms are their favorite feeds. Formulated feeds can also be self-aligned, formulated as: fishmeal 21%, cakes 19%, energy feed 37%, alfalfa 12%, minerals 1%, yeast 5%, multivitamins 2%, adhesive 3%. The artificially cultivated dark yellow large-brown seedlings were fed with compound feed, and the feeding amount was 3% to 5% of the weight of the jaundice, and they were fed once or twice a day (depending on the weather and water temperature). Quantitative principles, feeding 20 grams of Scutellariae seedlings can grow to 200 grams to 300 grams a year, high breeding efficiency. Mudworms mainly feed on the excrement of jaundice and the uneaten scutellaria feed in ponds. Loach naturally breeds quickly. When the proportion of muddy ponds is greater than 1:10, the bran can be fed once a day.
IV. Feeding management The growth season for yellow locusts and loach is from April to November, and the peak season is May to September. During this period, the management must be “difficult†and “fineâ€, that is, patrol pool, ground management, and discovery. The problem is solved quickly. Observe carefully the growth status of the jaundice and mud in the pond so that appropriate measures can be taken in time. The habit of jaundice and loach is nocturnal. Keep the water in the pool fresh and the pH is between 6.5 and 7.5. The water level is suitable.
Fifth, prevent rickets and prevent rickets. Once the onset of jaundice, the treatment effect is often unsatisfactory. Must be disease-free, disease-prevented, and prevention-focused. Can not rely on the saying that "Huang Biao is not sick". Always use 1ppm ~ 2ppm bleach Quanchiposa, regular use of copper sulfate, "Zhi Ling Ling," "Sturgeon transfer legislation stop" Quan Quan disinfection, prevention of disease. Raising the loach in the astragalus culture pond can also reduce the jaundice disease. Because the loach is in the culture pond, they like to move up and down, and also eat the debris in the water body, which can play a role in purifying water and increasing oxygen.
Astragalus and loach are delicious and nutritious, and they are the best in freshwater fish. In recent years, due to artificial overfishing, pesticide poisoning, and environmental pollution, the resources of natural wild yellow locust and muddy grass have decreased, and the market is in short supply. Therefore, the development of artificial breeding of yellow sorghum and loach has great prospects. The compound feed is used to feed the scutellaria baicalensis, and the loach grows quickly. The loach is cultivated in the sassafras breeding pond with high efficiency. The high-yielding culture techniques are as follows:
