Huanghua, also known as squid, is a nourishing fish product that is popular with people because of its delicious meat, rich nutrition, and certain medicinal value. Huang Xi is a powerful player, easy to transport, and can be listed live. The development of artificial breeding of Astragalus has a certain market prospect.
The artificial breeding techniques of Astragalus are introduced as follows:
The techniques for artificially breeding Astragalus include the construction of Huangqianchi, selection and stocking of seedlings, artificial feeding and daily management.
1, the construction of Huang Xiaochi. Astragalus has strong adaptability to the environment. Some abandoned water bodies that are not suitable for breeding other fish and puddles and ponds that are not suitable for planting crops can be used as Astragalus. You can also choose a place where there is plenty of water and ventilation to build a pond. It is better to use a rectangular east-west direction in Huangshaochi, which is about 1 meter deep in the pool. The area depends on the scale of farming. Generally, 20 to 50 square meters is appropriate. The bottom of the pond, the wall of the pool, and the gaps around the pool must be plugged tightly to prevent the jaundice from escaping. Dianchi Lake must have inlets, outlets, and overflows to discharge sewage, change water, and prevent fish from escaping when the pool water is high. Each sluice must be equipped with a barrage facility. In order to facilitate the growth of Astragalus, it is possible to artificially imitate the natural environment for the yellow toads to inhabit, such as putting stones, roots in the pond, or planting aquatic plants such as water lilies in the pond.
2, seedlings selection and stocking. At present, artificially cultivated seedlings mainly come from the market to purchase, capture or collect the fertilized eggs of Scutellaria baicalensis into hatchlings. The seedlings selected for stocking must be free from injury, disease, and robustness. The body surface should be smooth and the body color should be golden yellow. Usually, about 30 tails per kilogram will be selected. If the seedling size is too small, it will affect their feeding. And gaining weight, can not be harvested the same year, stocking seedlings must be neat specifications, the same size, otherwise they will fight for food and mutual slaughter. Stocking densities can be raised to about 25 larvae per square metre. Early spring stocking seedlings is better, it is conducive to the early start of food and extend the growth period.
3, artificial feeding. Astragalus is a carnivorous omnivorous fish with a wide range of sources. Such as small fish, shrimp, animal viscera and waste, shake, cocoon, snail meat, rice, melon, vegetable crumbs and so on.
The feeding of jaundice should be adhered to timing, positioning, qualitative and quantitative feeding. Namely: Generally, after feeding in the evening, it will set up a fixed place for the feeding of the yellow eel, which will help the yellow eel to eat and eat. It is convenient for us to observe the eel's eating condition and clean up the remaining bait; the bait must be fresh, live bait; The amount of feed to be fed is approximately 6% of the weight of the scutellaria baicalensis. Feeding should be adjusted according to the eating conditions of the jaundice on the previous day. It is advisable to have a little surplus after feeding. Feeding Astragalus, can not be cut for too long, when the vote is stopped, otherwise it will affect the growth of Astragalus.
4, daily management. In addition to doing a good job of baiting, the key is to prevent the yellow cockroaches from escaping, do a good job of water quality, and do a good job in preventing heat and wintering:
(1) Anti-escape. Always check and maintain the anti-escape equipment of Huang Yu Chi. In rainy days, especially in heavy rain, drain water in time to prevent it from escaping from the drainage hole.
(2) Water quality management. Keep the pool water stable and the water quality fresh. The water depth of the Huangqi pool should be between 15 and 25 cm. During the hot season, the water can be deepened again. When the weather changes suddenly (when the rain is fine or the weather turns sunny) and the weather is hot, it is necessary to inject new water in time to prevent the jaundice. Hypoxic frequent floating head, adhere to regular water changes, high temperature season must change the water every day, clean up the residual food.
(3) Do a good job of preventing heatstroke and overwintering. The suitable water temperature for the growth of Astragalus is 15-28°C, and 28°C or above has a bad influence on feeding. Therefore, it is necessary to do a good job of preventing the heat in the hot season. Shady crops are planted around the Huangqian Lake; Pool water, timely injection of well water or spring water (temperature difference can not be too different). When the water temperature is below 10°C, the jaundice is in a dormant state, so when the temperature drops to about 15°C, it should be fed with high-quality bait so that the jaundice can feed in large quantities and store nutrients for hibernation. When Huang Xi is hibernating, he must pay attention to keep the pool mud warm and warm. To prevent frostbite frostbite, frozen to death. In addition, we must pay attention to the prevention of rats and other hazards.
