Alice mouth red? Also known as "white fish", "white bars", etc., is a rare freshwater fish. Its delicate meat is delicious and nutritious, and it is favored by consumers. It is also suitable for pond breeding, polyculture, and cage culture outside ponds. According to the recent experience in breeding, the total yield of the pond can reach 400 kg per mu, and the profit per mu can reach 6000-7000 yuan. It is one of the varieties with better economic returns in freshwater fish varieties. The technical points of raising the fish in the pond are now described as follows: 1. Pond conditions: Adequate water supply, good water quality, flat bottom, and less silt. The pond area is generally about 3 to 8 mu, and the water depth is 1.5 to 1.8 meters. 2. Clear pond disinfection: 15 days before stocking, the ponds are disinfected, and the calcine is turned into lime milk for Quanchiposa. The water depth of 10-20 centimeters per mu is between 75 and 100 kg to kill pathogens and other predators. After the drug disappears, fish can be released after injecting more than 50 cm of water. 3. Seed stocking: acre put 10-15 cm winter fish 800 ~ 1000 tail, size and size should be basically the same. The amount of cultivated white bream fish was raised, and 100-200 acres were placed. Pull nets before transport to prevent injuries. 4. Scientific feeding: feeding chilled fish and artificial compound feed. Feeding methods: 1 feeding chilled fish. Feeding of fish must first undergo a domestication process. Fish broilers made of chilled fish are fed 3 to 5 centimetres a day, 4 times a day; minced chilled fish are fed over 10 cm. There are two feeding methods. One is fixed-point feeding, which is eaten within 2 hours after each feeding; the other is artificial throwing, and the injection of red ink does not come to snatch food. 2 Feed buoyant pellet feed (above 35% crude protein content). The feeding method is basically the same as the feeding of chilled fish, and the feeding amount is generally controlled within 1-1.5 hours after feeding. Feeding times are 2-3 times per day. It is also necessary to pay attention to the regular observation of the fish’s food, activities, and weather changes, and to flexibly control the amount of feeding. 5. Feeding management: The first phase, after stocking until April, is within 20 cm in size, mainly relying on the cultivation of plankton. In the second stage, after the plankton in the pond has finished eating, it is necessary to manually feed the palatable bait. What kind of bait is to be fed and what kind of bait should be used for domestication. The bait specification should be small to large, and the palatability should be good. Throughout the breeding process, the water quality remains fresh and the transparency should be controlled at 30-35 cm. When the water quality is too strong and the food intake of fish is reduced, new water should be injected in time and appropriate amount of lime water should be used to regulate the water quality. Microbiological agents can also be used to improve water quality. At the same time, aerators should be turned on for oxygenation in a timely manner to prevent flooding of fish. 6. Disease prevention and control: Alice red? The main diseases are parasitic diseases, especially small melon insects and ringworm disease. These two kinds of parasitic diseases are often concurrent, fierce and dangerous. To prevent parasitic diseases, besides doing pond lime clearing ponds and dipping medicines for fish species, the process of aquaculture should be regularly preventive. Regular use of crystal trichlorfon or protozoal net disinfection, available extermination orally, etc., to prevent better. 7. Fishing and transport: Alice mouth red? Good jump, pull nets should be covered with nets. Due to the awkwardness of the mouth, it is easy to be injured and should be handled carefully with water. If they are not injured when they are arrested, the survival rate of artificially raised Aphrodite is also high.
