Tips for Pond Culture Technology

Taihu whitefish scientific name mouth red, also known as mouth, white fish, white, body length, side flat, head straight back, upper mouth, jaw strong, upturned, erect in front of the mouth, large eyes, small scales, Sideline scales 80~93, dorsal fins with strong and smooth spines, anal fins III, 21~25. The fish live in the middle and upper layers of the open water area. It is fast-acting, good-jumping and ferocious. It feeds on other small fish, and individuals weighing 0.5 kilograms can eat about 10 cm of clams and sturgeon species. It grows rapidly and has a large body size. Common individuals range from 2 to 2.5 kilograms, and the largest is up to 10 to 15 kilograms. They are distributed throughout major river systems in the country. As an important special aquatic product variety in the Taihu Lake Basin, its breeding prospects are very promising. My county's aquacultured fish yields more than 230 kilograms per mu, the mu production value is 7,000 yuan, the mu cost is 2,600 yuan, and the net income of mu is 4,400 yuan. The main techniques for breeding Aphrodisiac are now described as follows: The pond has sufficient water, fresh water, flat bottom, and less silt. The pond area is generally about 2 to 15 mu, and the depth of water is 1 to 2 meters. The pond level is more than 0.5 meters above the flood level. 2. Clear pond disinfection About 15 days before stocking, pond clearing ponds are disinfected, and the whole pool is splashed with lime into lime milk. The amount of water used per mu is 10 to 20 cm, 75 to 100 kg, and the main pathogens and other enemies are killed. Harmful creatures. After the drug disappears, fish can be released after injecting more than 50 cm of river water. 3. Seed stocking requires 200-400 kg per mu, 800-1000 per mu for one-year-old fish, fish size of 5 cm or more, preferably 10-20 cm, and a second-grade fish species with a 500-g or lower acre 400 to 500, basically the same size and size. Adapted to take care of flowers, acre 50. Pull nets before transport to prevent injuries. 4. Feeding Science Feeding There are chilled fish and live bait fish. The live bait is required to be 1/3 to 1/5 of the length of the rearing fish, and the above layers of fish are better, such as white locust, flower pod, and quail. Fish, whitefish and other small fish. Feeding methods: 1 feeding chilled bait, domestication of fish must be through the process of domestication, 3 to 5 cm when feeding broiled fish made of fish, 4 times a day; 10 cm above the feeding of chopped ice fish Piece. There are two feeding methods: one is fixed-point feeding, which is limited to two hours after each feeding; the other is manual throwing, and the injection of red ink does not come to eat. Artificial breeding Alice mouth red? Under normal circumstances, the bait coefficient is about 4; 2 feed live bait fish, fed once every 5 to 7 days, the amount of feed for the mouth red mouth, 1 to 2 times the amount of pond, eat Feed it immediately afterwards and postpone the feeding time. Also pay attention to the frequent observation of fish eating, activities and weather changes, and flexibility in the amount of feeding. 5. The first stage of feeding and management, after stocking, until April, the specifications within 20 cm, mainly rely on the cultivation of plankton, the water quality requirements to adapt to the growth of plankton, mouth red, fast growth. 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 about 30 cm. When the water quality is too strong and the food intake of fish is reduced, new water should be injected in time to regulate the water quality, and oxygenation measures such as aerators or water pumps should be started to prevent fish from lacking oxygen. 6. Disease prevention and control of parasites should pay attention to parasites, especially small melon insects and ringworm disease, these two kinds of parasitic diseases are often concurrent, to attack fierce. According to the county's aquaculture situation, the disease has occurred in the spring, autumn, and winter except for the high temperature season in summer. Aphrodisiac? Pond culture needs to maintain a proper fertility, in addition to fertilizer pond, the cultivation process should also be timely fertilizer, so that the transparency of the pool to maintain 30 to 40 cm. Prevention of parasitic diseases, in addition to doing pond lime clear ponds, fish drug dipping, the aquaculture process should be regularly carried out drug prevention, elimination of net protozoa, internal use of drugs can kill insects, prevention effect is obvious. 7. Fishing and transport Alice red? Good jump, nets should be covered when pulling nets. Due to the irritable mouth, it is prone to injury, and improper operation can bring certain difficulties to long-distance transportation. If it is kept unharmed during fishing, the survival rate of artificially cultivated Aphrodisiac is also high.
