Characteristics of golden thread carp Gold wire carp is most suitable for the growth temperature is 20-32 °C, not only resistant to hypoxia, but also resistant to high-density culture, can survive in many hypoxia shallow water environment where fish can not survive, eating a wide range of staple foods Animal-based dip, also eat plant feed; short cycle, rapid growth and development; and there are auxiliary respiratory organs, the water will not die in 24 hours. Conducive to transportation and sales.
Choosing a pond to cultivate a goldfish pond is best to have a pond that is not contaminated by industrial waste water. A small area of ​​pond is particularly suitable. Dozens of square meters or even a few square meters of small earthen pond can be cultured. River ditch, paddy field, post-house waste sewage, etc. can also be used, more suitable for rural family farming. If you want to intensively produce a high-yielding fish pond with an area of ​​600-1200 m2, the water depth is 1.2-1.5 meters. Due to the habit of mutual grunts and strong meats, the stingrays strive to keep the specifications of the fish species neatly. The fish species with a size of 5-7 cm is preferred, and the stocking rate is generally 220 per m, and the number is 27000-10000 per 667 m. It is appropriate.
Feeding of the bait and feeding the fish should be based on animal feed, supplemented by vegetable feed. The main animal foods are plankton, snails, small trash fish, fly maggots, slaughterhouse waste, poultry intestines, etc.; plant foods are used for various foods and by-products. After stocking, plankton and powdered feed were first fed. Then feed the fly maggots. The fly maggots can be bred with manure, or they can be bred in small septic tanks beside the ponds. They can also be cultivated on the waters around the pond. Under artificial breeding conditions, it is also possible to feed various food baits, vegetable baits and various bean cakes, bean dregs, bran, etc. With the rapid growth of fish, it is best to feed animal feed more. Feeding fresh oysters and increasing animal protein supply is an important guarantee for the high yield and stability of goldfish. However, casting materials are to be determined in four stages, namely, "time, positioning, qualitative, quantitative" feeding. In addition, the feed should ensure sufficient investment. When the temperature is between 22 and 30 degrees, the daily feeding amount is 10%-15% of the fish's body weight. When the temperature is between 12 and 22 degrees, it is necessary to gradually reduce the amount of feeding and feed it daily. -3 times.
Disinfection and Prevention of Diseases Before the fingerlings enter the pond, they must use clear lime or bleaching powder to disinfect the clear pond, and then use human and animal feces to fertilize the water. The fry are sterilized with 4% saline solution. In the season of fish disease, 100 μl/L of bleaching powder is used to adjust the spillage of the whole pond every 10-15 days, or antibiotics such as oxytetracycline are mixed in the diet to effectively control bacterial enteritis. The use of 70 μl/l copper sulphate and ferrous sulfate (0.5:0.2) dissolved water in the Quanchiposa can be used to treat the disease and the disease. However, it is also possible to alternately use quicklime, bleach, and cupric sulfate every two weeks. Adherence to the disinfection and prevention of medication can effectively control the prevalence of fish disease.
Strengthen the regulation of water quality As the high-density breeding water is easy to age and cause hypoxia, although it will not be deadly, the difference in dissolved oxygen will inhibit the growth of fish. Fresh water can increase metabolism and promote fish growth, and new water or rotation should be added on schedule. Part of the water regulates water quality as well.
