The main pond raises the Ukrainian demand for the size of the pond is not high, suitable for a family breeding, is a small investment, quick, high efficiency of the rich project. The proper amount of fertilizer and fish and omnivorous fish can use a large amount of plankton in the pond and the residual bait and excrement of the black quail to purify the water, comprehensively utilize and increase the benefits and other effects. Due to the abundant feed of Chinese black quail and the rapid growth of fish, there is no need to worry that the set of fish will be eaten by black quail. Since Umberria is mainly based on animal foods such as small fish and shrimps, it should be based on the actual local conditions, taking into account the abundance of the source of the bait, moderate breeding, and should not be blindly developed. l. Pond construction. Site selection and requirements: The test pond can be a pond in the back of the house, close to the water source, and has an area of ​​1.5 mu, a depth of 1.5 m, a slope ratio of 1:1.5, and a pool raft that is 60 cm above the water surface, and is relatively wide. Barrier facilities: Wuhuan has a strong ability to jump, especially in thunderstorms, Uzbek will flee with the rain water. Therefore, around the pond with polyethylene sheeting, the bottom buried in the soil 10cm, the upper part of the 埂1.5-2m, and then outside the conditions to add a bamboo fence wall as a fence to protect the fence, anti-theft role. Set concealed objects: In the summer, the water hyacinth is stocked on one or both sides of the pool, which accounts for 1/10 of the total area of ​​the pond. It provides a rest area for the Wuhuan, and plays a role in blocking the sun and reducing the water temperature. 2, seed sources and stocking. Sources and requirements: The main acquisition is the acquisition of young species of black peony from natural lakes and rivers. The specifications are basically the same, the body is robust, and the fish body surface scales are intact without damage. Try to avoid too large a gap in specifications to prevent individuals from catching food. Stocking quantity: A total of 118.5 kg of Chinese black quail species with an average size of 8 tails per kg was stocked. Cultivating conditions: 1 white pheasant 3kg (40/kg); 2 bream 2kg (60/kg); 3 sterling silver bream 20kg (20/kg); 4 bream bream 1kg (70/kg) . Disinfection: All fish species were sterilized with 5% saline for 5-10 minutes before stocking. 3, feeding. The type and source of bait: The bait of black locust is dominated by animal baits such as small trash fish and shrimp. It is mainly acquired from the Fisheries Fisheries Department in the Lake District and is booked in advance every day. Feeding: Do not feed immediately after stocking, wait for a period of time to allow them to adapt to the pond environment, and then feed the feed when the water temperature reaches 15°C or more. At the beginning of the feeding, they are placed in a fixed position in the pond and fed in small amounts to acclimate their active feeding. Later on, they gradually increase the amount of feeding according to the day's food intake. The total weight of the fish pond is generally 6%-8%. Sets of fish do not feed bait and feed mainly on plankton and bait. Feeding is carried out at 9:00 a.m. every day, and the "Four Sets" will be implemented. A total of 2265kg of small fish and shrimps were fed throughout the year. Requirement: Umbilica food is vigorous at 25-30°C, and in July, August and September, it is the peak of its food intake. The amount of bait should be increased appropriately, but it can be finished on the same day. Food intake decreased gradually in October. Feeding persisted until early November. 4, management. Water quality: The water quality requirement of Wuhuan is not high, and the high-density main breeding needn't worry about pan-tang. The normal water depth is controlled at about 1.2m, and the high temperature season is controlled at about 1.5m. In addition to occasional floating heads during the rearing period, the black baboon never floated over. Disease prevention and treatment: T. wuyi has a large amount of food, many excretions, and it is easily fattened. It is easy to reproduce a large number of plankton and red worms in the water to kill once every month with 90% crystal trichlorfon and the dosage is 0.6ppm. Note: Whenever new water is added. When a large amount of rainfall, high temperature, or steep fall, the food intake of Wuji will decrease, and the amount of feeding should be properly adjusted. Anti-escape, anti-theft: Thunderstorms and flood seasons need to prevent pool collapse and fish escape. There must be someone watching at night.
