Umbellolus is a carnivorous fish. In the past, wild fish were used as feed for breeding. However, due to the limited resources of wild fish, the development of the black quail farming industry has been limited. At present, the use of artificially expanded pelleted feeds has achieved good results in the breeding of black tadpoles, but it is difficult to domesticate black tadpoles to normal intake of artificial pellets in the breeding. The method of transferring Ujita to domestication is described as follows:
1. Pond conditions Breeding Ukrainian water is generally suitable for 3 to 5 mu of water. About 15 centimeters before the seedlings were soaked, 150 kg of lime were used per acre, and Quanchipi was sprayed and disinfected. After 3 days of disinfection, the pool water was added to a depth of about 1 meter. After the disinfection of the clear ponds, stick to the ponds before and after the sunrise every morning to remove the frog eggs in time so as to prevent the frogs from multiplying and affecting the domestication and survival rate of the black storks.
2. Set feeding area In the middle of the south bank of the fish pond, use a wooden board to build a feeding table that extends 3 to 5 meters into the pool for artificial feeding or placing a feeding machine. On the water surface around the feeding table, a square or triangular enclosed feeding area of ​​15 to 20 m2 is fixed with bamboo, plastic pipes, etc., and the extruded feed is put into it when feeding to avoid the feed from floating around. The frame is fixed with a bamboo pole or the like so that it can rise and fall with the water surface. Before the fishes enter the pond, some floating aquatic plants (such as duckweed, etc.) are planted in the feeding area, and the planting area accounts for about 2/3 of the area of ​​the feeding area. According to their habits, they will often cluster under the floating plants in the feeding area, which will greatly facilitate feeding and domestication. After the domestication and conversion of food have been completed, when U. sinensis begins to normally feed on the bait station, the floating plants around the bait station may be removed.
3. Seedlings to be released In order to facilitate domestication and ensure the survival rate, black-headed larvae with a body length of 2 to 3 cm are generally used. The fry requires a healthy body and neat specifications.
4. After feeding and domesticating fry into the pool, they began to feed the natural organisms such as Cladocera and Copepoda in the pond. When the natural food in the pond is insufficient, feeding and domestication can be started. The specific domestication can be roughly divided into three steps: 1 domestication of the Ukrainian cluster feeding. The fresh wild fish is first processed into fish paste. Since some floating aquatic plants have been planted in the feeding area, most of the fry will cluster in the feeding area. During domestication, the sound is generated by percussive drums and other methods to stimulate the fish, and then the fish slurry is splashed into the feeding area and repeated once every tens of several seconds for 20 to 30 minutes each time. Domestication work must be patient and meticulous. Whether the fish feed or not, they must adhere to it. After a week or so of domestication, the black sapling seedlings will form conditioned reflexes and gradually develop habits of spotted colonies. 2 Domesticated black buckwheat feeding compound feed. When Ujjain grows up to eat No. 0 extruded pellet feed, it begins to acclimate and feed on extruded feed. The fresh wild fish (like the feed used in the previous period to ensure that the feed odor does not change) are beaten, diluted with water (usually the ratio of fish and water is 5:1), and then filtered with gauze to remove the fish bones and meat. Residue, and then use the filtered fish slurry soaked artificial pelleted pellet feed for 10 minutes, 500 grams of fish slurry per kilogram of feed can be. Before taping, drums and other sounds are made to stimulate the fish to feed, and then sprinkle a small amount of feed soaked with fish paste. This repeats every 10 seconds, each training 20 to 30. minute. After a few days of domestication, Chinese black buckwheat gradually adapts to feeding artificial extruded pelleted feed. 3 The transition to full use of artificial expansion pellet feed. When all Ukrainian wolfberry can feed on the feed table, they gradually reduce the amount of fish soaked in the soaked feed. After about one week, the fish slurry can be used completely. At this point, the domestication is completed and the normal feeding phase is completed.
5. Precautions for normal breeding 1 In the normal feeding stage, the expanded feed is no longer soaked with fish paste, but it should be soaked with fresh water, and the water should be expanded and softened before feeding. The soaked pellet feed will absorb less wastewater from the pond and reduce the breeding disease of the black turtle. The surface of the soaked feed will be softened, which can reduce the chance of damaging the intestine and reduce the incidence of intestinal inflammation. The soaked feed is also easier to absorb. 2 Be patient and careful when feeding. When feeding the feed, it should be done as soon as possible that feed into the water can be quickly eaten by the fish. Do not pour the feed into the pond at one time, so that the feed is not lost by the fish, resulting in reduced feed utilization. (3) When the domestication of Wuhuan enters the normal feeding stage, conditions may be adopted for feeding by a feeding machine. This not only saves human resources, but also feeds evenly and improves feeding quality.
