Astragalus is delicious and nutritious and is one of the most prized freshwater fish. In recent years, due to artificial overfishing, pesticide poisoning and environmental pollution, the resources of natural wild astragalus have been reduced and the market is in short supply. Therefore, the development of artificial breeding of Astragalus has broad prospects. After six years of research and practice, the Huanghua project team of the Mingte Fisheries Research Institute in Macheng City, Hubei Province, used compound feed to feed Astragalus membranaceus. Astragalus membranaceus grows quickly and has high benefits. The high-yielding aquaculture technology is introduced as follows:
First, build a breeding pond. The ponds that feed the yellow pheasants should choose to use the cement pools and earth pools where they are sheltered from the wind to the sun, where the environment is quiet, and where the water sources are convenient. They can also be cultured in cages in reservoirs, ponds, gutters, and rivers. The size of the pool area is generally 20 to 50 square meters, too big to manage. If the cement pond is used to raise the earthworm, it must be dealt with before the seedlings are removed in order to store the yellow seedlings. If earthworms are used to raise earthworms, the soil is hard and the bottom of the pond must be compacted. The shape of the rearing pond is determined by the topography. The square can be round, and the depth is 0.7-1 m. Whether it is a cement pool or an earth pool, it must be filled with a mud layer at the bottom of the pool, 30 cm thick. Fertilizers containing more organic matter are better, and it is beneficial to dig out the caves. Pay attention to the installation of the inlet when building the pool, overflow, water depth to maintain 10-15 cm. Water inlets and overflow outlets were spared by barring the fish nets to prevent them from fleeing. About 10 days prior to planting, the plants were thoroughly disinfected with quicklime, and the pool water was drained and fresh water was injected 3-4 days before planting.
Second, choose a good yellow seedlings. Raising seedlings of Astragalus is the key. Astragalus seedlings are best cultivated by artificial domestication of the dark yellow or large golden spotted species, can not use the colored seedlings and no domesticated seedlings, but can not believe the "grand". The seedlings of Scutellaria baicalensis should be 50-80 per kilogram, which is too small to eat well, and the survival rate is also low. Stocking density is usually 1.5-2 kg per square meter.
Third, feeding compound feed. Firstly, the feed stand is installed, and the feed stand is made of wood or plastic board. The area is set according to the size of the pool and is 5 cm below the water surface. Then put the seedlings of Astragalus, do not feed the first 3-6 days, so that the Astragalus suitable for the environment, from the 4th to the 7th day began feeding feed, feed feed around 7:00 pm every day, the best, when the highest intake Huangpi. Artificial rearing of jaundice is mainly based on feed, and some pupa, locust, and mealworm are properly fed. Artificially domesticated jaundice, compound feed and earthworms are their favorite feeds. Formulated with feed: 21% of fishmeal, 19% of cakes, 37% of energy feed, 12% of barium (dry weight), 1% of minerals, 5% of yeast, 2% of multivitamins, and 3% of binders. Artificially cultivated deep yellow giant catfish seedlings were fed with this compound feed and the feed amount was 3%-5% of the weight of the astragalus. Feeding 1 to 2 times a day (depending on the weather and water temperature) Using the principle of timing, quantitative, feeding 20 grams of astragalus seedlings a year can grow to 200-300 grams, high breeding efficiency.
Fourth, feeding and management. The growth season of Astragalus membranaceus is November, and the peak season is May-September. During this period, the management must be “difficult†and “fineâ€. That is to say, the ponds are patrolled and diligently managed, and the problem is solved quickly; the ponds and jaundice are carefully observed. Dynamic growth so that appropriate measures can be taken in time. Huang Xi’s habit is to stay awake. In the morning, the remaining feed in the pool should be fished out in time so as not to affect the quality of the water and keep the water in the pool fresh. The pH of the pH is between 6.5-7.5. The water level is suitable.
Fifth, prevent rickets. Take care to prevent rickets. Once the onset of jaundice, the treatment effect is often unsatisfactory. There must be no disease to prevent it first, and there must be a way to prevent it from becoming ill and prevent it from being healed. Can't believe in the lie that "Huang Xi was not sick". Frequent use of 1-2ppm bleach Quanchiposa, regularly disinfected with copper sulfate Quanchipu, every spring and autumn with crystal trichlorfon anthelmintic.
