Tianxia Redfish is a new precious fish species that combines ornamental, fishing, food, and health care. It is a young fish species that has been bred and transformed from long-term improved varieties. , blood vessels and internal organs. The whole body is pink, bare and scaleless, gorgeous like peaches, if the skin is creamy, it is beautiful and graceful. Body side two silver belts run through the body. Eyes, fins, whiskers, tails are bright and bright, colorful. The adult stage still has the above characteristics. The form is like a beautiful Wang Zhaojun, so it is also named Zhaojunyu. Tianxia red fish back to tender and no thorns, refreshing plastic, fat but not greasy. The price of the commodity fish market is equivalent to 2 to 3 times the price of valuable fish such as long-ringed fish, big-mouthed oysters, and fish-tailed fishes.
Tianxia Redfish is a tame, food-rich and disease-free species with a suitable temperature range of 0-38°C and a suitable pH value of 6-8.5. Pond culture, such as large-scale species of wintering fish, the use of artificial feed, raised to the end of the year, per acre can produce Tianxia Redfish back 800 to 1000 kg, profits of more than 10,000 yuan. The Tianxia redfish return to pond culture technology is introduced as follows:
First, the pond clearing selection area of ​​2000 to 5000 square meters, water depth of 2 to 2.5 meters, less silt, good water retention pond. The water source should be sufficiently free from pollution, and it should be convenient to enter and drain water. Each 5000m2 pond is equipped with a 3kW aerator. Fish stocks should be leveled at the bottom before stocking and disinfected with clear lime or chlorine preparations. Dry method clear pond, 60-80 kg of lime per acre or chlorine preparation 20 mg / liter; water clear pond, water depth of 1 meter, 150 kg of lime per acre or 30-40 mg/L of chlorine preparation, kill bacteria Wild fish.
Second, to put the species into the market for the year to meet the specifications, to put more than 10 cm of red fish back to the large-scale species of winter fish species, stocking 1,000 to 1300 per acre, while polyculture 150 g / 200 tail tail, 200 g / Float 20, 50 g/tail bream 40. The delivery time is appropriate for the first and the middle of January. All fish species should be physically strong, disease-free and injury-free. Before the lower pool, they should be soaked with 20 mg/elevated potassium manganate for 5 to 10 minutes, or 3% to 5% salt water for 5 to 10 minutes, or 20 mg/L. Malachite green dip 10 to 15 minutes disinfection.
Third, the feed formulation feed nutrition must be comprehensive, balanced, protein content of more than 30%, moisture content should be less than 10%. Feed pellets with a diameter of 2 to 3 mm are preferred. Reference formula: fishmeal 10%, bran cake 15%, yellow corn 23%, third grade powder 12.5%, animal fat 2%, no calcium phosphate 1%, mixed vitamin 0.5%.
Fourth, feeding the feed side of the pond set up feeding table 1 to 2, fixed feeding. At the beginning of the feeding, the whistle training was used to form a conditional reflex feeding. Feed twice a day, 8 to 9 am and 6 to 7 pm each. Daily feed amount: The previous period (before June) is 1% to 2% of the fish body weight; in the middle period (June to September), it is 3% to 5%; and the later period (after September) is 2% to 2.5%. Feeding by hand, and mastering the rhythm of “slow, fast, and slowâ€, start with a slow shot, fast-shoot when fish is caught in a feeding queue, approach feeding, and slow-jump when the sniffing speed slows. At the same time, the amount of feed should be flexibly adjusted according to weather changes, water temperature, and fish feeding conditions.
Fifth, water quality regulation requires that the water quality be kept fresh, and the transparency should be in the range of 30 to 35 cm. The dissolved oxygen in the water should be kept above 3 mg/l. In order to prevent water quality from aging, new water should be added periodically. In June and August, every 10 to 15 days, fill 20 to 30 cm deep. Every 20 to 30 days, after using 10 to 15 kilograms of quicklime, the whole pool is splashed to adjust the water quality. During the hot season or rainy weather in July-August, attention should be paid to the changes of dissolved oxygen in water. If the dissolved oxygen in water is found to be less than 3 mg/L or the fish is found to have floating head symptoms, the amount of feed should be reduced and the aerator be increased in time. .
Sixth, the fish disease prevention and control Tianxia redfish back resistance is relatively strong, generally not prone to fish disease. If intestinal septicemia occurs, it can be continuously fed with oxytetracycline (180 grams per 100 kg of feed) for 7 to 10 days, while potassium permanganate (2 to 3 g/m3) can be poured in the whole pond; bacterial rot can be used for 0.03. g/m3 furazolidone whole pond spilled.
