Tianxiahong? is a new precious fish species that combines ornamental, fishing, food, and health care. Its larvae are crystal clear and transparent, showing muscles, 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 fish stage still has the above characteristics, like the beauty Wang Zhaojun, hence the name Zhaojun. Tianxia red meat tender without 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 the long snipe, bigmouth bass and fork tail.
Tianxia Red has a tame temperament, mixed feeding habits, few diseases, 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, can produce 800 to 1,000 kilograms per 667 square meters, profits of more than 10,000 yuan. Tianxia Red Pond Culture Technology is now introduced as follows.
First, the pond clearing selection area of ​​2,000 to 5,000 square meters, water depth of 2 to 2.5 meters, less silt, good water retention, adequate water sources, no pollution, convenient drainage and drainage ponds, equipped with 3 kilowatts per 5000 square meters aerator. Fish stocks should be leveled at the bottom before stocking and disinfected with clear lime or chlorine preparations. When dry cleaning ponds are used, 60-80 kg of quick lime or 20 mg/L of chlorine preparation is used per 667 square meters; when water depth is 1 meter, there are 150 kg of quick lime or 30-40 mg of chlorine preparation per 667 square meters. l to kill germs and wild fish.
Second, to put the species into the market for the year to meet the specifications, to put more than 10 cm of Tianxia red? Large-scale species of wintering fish, stocking every 1000 square meters per 667 square meters, while polyculture 150 grams / 200 white tail, 200 grams 20 tails, 50 g/tail squid, 40 tails. 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 next tank, 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 1 to 6 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, 667 square meters of lime 10 to 15 kilograms of slurry after Quanchiposa to regulate 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. .
Six, fish disease prevention and control Tianxiahong? Stronger disease resistance, generally not prone to fish disease. If intestinal septicemia occurs, oxytetracycline (180 g) per 100 kg of diet can be fed continuously for 7 to 10 days, while potassium permanganate (2 to 3 g/m3) can be used to splash the whole pond. The occurrence of bacterial gill disease can be used 0.03 g / cubic meter furazolidone whole spill.
