Xiangyun Yunxiao Yuncheng adult breeding technology
Pond culture is divided into two types of stocking, one-year adult fish farming and two-year adult fish farming. 1. For those ponds with fertile water and abundant feed, the large-scale summer fish species that have been rapidly bred can be directly stocked into adult fish ponds or spring fish ponds and mixed with other domestic fish at a proportion of 150-200 tails per mu. Do not put in other oysters and squid species. After 4-6 months of breeding, individuals in Xiangyun yunnan can reach 400-600 grams, and the yield per mu can reach 80-100 kg. Individuals up to 500-750 grams in Xiangyun, per mu up to 100-150 kg. 2. For large water surface stocking of Xiangyun wolfberry and Xiangyun wolfberry, two-year adult fish breeding is generally adopted. Both the first-year hatching fry and the spring-bearing fish species with tail weight of about 50-100 grams are first introduced to the fishpond for single use. Raise or polyculture. The main raising generally puts 1200-1500 tail spring slices per mu, and with 10% of glutinous and squid species, Xiangyun wolfberry can produce 750-1000 kilograms per mu, and Xiangyun wolfberry can produce 1500-2000 kilograms per mu. In addition to the regular ratio of four home fish, the polyculture can be put into 300-400 tails of Xiangyunjing and Xiangyun Quchun slices per acre, which can increase 175-250 kilograms of Xiangyun wolfberry and 350-500 kilograms of Xiangyun wolfberry. According to the biological characteristics of Xiangyun Mountain and Xiangyun Mountain, in addition to feeding and managing according to the conventional methods, ponds that store Xiangyun Mountain and Xiangyun Mountain should also pay attention to the following points: 1 According to Xiangyun Mountain and Xiangyun Mountain, The characteristics of low temperature, in the early spring and late fall season should strengthen the artificial feeding, as long as the water temperature above 10 °C can be feeding, the daily feeding rate is generally 1%-3% of fish weight, divided into 1-2 feeding, with Improve the production of Xiangyun and Xiangyun. 2 Science should be used for bait, so that "four look" and "four set". "Four-seeing" means looking at the season. From January to October and December to December, the temperature and water temperature are low, and the investment should be less. The temperature from May to September and the water temperature are high. It is the best season for fish growth and should be cast more. Look at the weather. Sunny days can be more cast, rainy days should be less cast, Tianyin windless or heavy rain will stop before the vote, fog, low pressure, and other fog after the re-cast; see the water, fertilizer can be normal feeding, thin water increased Feeding with fertilization, the water color is too strong, can reduce the amount of feeding; see the fish, the bait is eaten within 2 hours of full treatment, can increase the feeding, if there is leftover bait after 2 hours, can be reduced as appropriate Feeding. Four fixed timing, quantitative, qualitative, positioning. 3 During the breeding cycle, strict water quality management, and always maintain the "fat, live, tender, cool" water quality standards, the water color is light green, or yellow-brown is better, transparency is controlled at about 30 cm, especially in the breeding high temperature season, should Pay attention to the frequent addition of new water, promote the metabolism of fish and accelerate the individual growth rate of fish. 4 Regular disinfection to prevent the occurrence of parasitic diseases and other diseases. Usually 40ppm quicklime or 0.5ppm bleach or trichlorfon and other drugs regularly disinfected once. As long as the management is strengthened, the breeding of Xiangyun Mountain and Xiangyun Mountain can achieve high yield and high efficiency. In spring, the fish is cultivated into fish, and the size of Xiangyun Mountain is generally 500-750 grams, and that of Xiangyun Mountain is 1000-1500 grams. The effective fisheries in Changsha-Zhiqu area have been mixed and cultivated for three consecutive years. They will produce 150-200 kilograms of Xiangyun wolfberry per acre without increasing the yield of other fish. This will increase the net profit by nearly one thousand yuan. Hanshou Xisongshan Township, a single high-yielding experimental pond, produces more than 620 kilograms of Xiangyun Mountain, the largest individual reaches 1.5 kilograms, and the net profit per mu is 2,000 yuan. Reservoirs and lakes breeding Xiangyun wolfberry and Xiangyun wolfberry do not breed offspring and are easy to fish. They are suitable for large-scale storage of reservoirs and lakes. When stocking, it should be noted that fish species specifications should require tail weights of 50 grams or more, generally about 50 to 10 tails per acre. It is necessary to strengthen management to prevent Xiang Yun and Xiang Yun’s escape from the water; at the same time, they should supplement according to the number of natural foods in the water area. Feed artificial bait. According to calculations, each net increase of 1 kilogram of Xiangyun wolfberry, Xiangyun wolfberry feed 3 kilograms of cake or about 2 kilograms of feed. Its input-output ratio is roughly 1:3. Cage culture Xiangyun wolfberry and Xiangyun wolfberry have strong disease resistance, intensive tolerance, mild temperament, low feed coefficient and wide source, so they are very suitable for cage culture. According to the experience of large-scale cages breeding in Xiangyun Mountain and Xiangyun Mountain in Chenzhou City, Hunan Province, the following should be done: 1. The fish species should be of the same specifications and density, and 50 grams of tail fish should be used per square meter. Stocking 150-200 tails. 2, early stocking, ground feeding. Before the end of February, the fish should be allowed to feed. Artificial diets can be fed at water temperatures above 10°C. Before feeding, the fish should be fed under starvation conditions. The fish should be fed 0.5%-1% of the body weight on the second day, and the fish weight should be 1%-1.5% on the third and fourth days. , Fish fed 0.5%-2% of body weight every 6 days, 3-4 times a day, each feeding time is about 30 minutes, since the seventh day, if the fish school has developed dense cable food The habit can be normally fed according to the daily feeding amount determined according to the temperature and fish species specifications, and fed at least 3 times a day. According to the fish feeding condition, up to one day can be fed 6 times, each feeding should be done Less amount of diligent cast to increase feed utilization. 3. Regularly hang medicine bottles to prevent the occurrence of parasitic diseases. Usually a 2-3 times of the breeding cycle, the first time in the cage placed fish stocking, the second time in early May fish disease season, the third before and after the beginning of autumn in August. The drugs are generally bleached powder and trichlorfon. The dosage depends on the size of the cage and the tolerance of the fish. Each cage is hung with 1-2 drugs for 3-5 consecutive days. Thanks to the strengthening of management, Dongjiang Reservoir's cage culture has been harvested for two consecutive years. After being examined and approved by experts from Hunan Provincial Science and Technology Commission, the net production of Xiangyunjing per square meter cage exceeds 100 kg, and the feed coefficient is 2.2 and 552.5 meters. The net income of the net box is over ten thousand yuan. The rice (lotus) field cultivates Xiangyun wolfberry and Xiangyun wolfberry, which grow fast, has strong resistance to stress, and has mixed feeding habits. It is an ideal breed of rice (lotus) field fish that has shallow aquaculture water and short growing season. In addition to conventional fish (lotus) field fish management requirements, but also need to pay attention to the following points: 1, rice (lotus) field fish, the growing season is relatively short, commercial fish specifications are generally about 0.5 kg, so to vote The species of fish is generally 200-300 mu per acre, or 100-150 spring fish. 2. Take precautions to prevent floods from rushing into the fields, causing Xiangyunshao and Xiangyunyu to escape from the water and preventing snakes, birds and other predators. 3, Xiangyun wolfberry and Xiangyun wolfberry are resistant to low temperature. In the late autumn and winter, they can still add water and fish, but they should pay attention to feeding some food baits properly to ensure the growth needs. When the water temperature is higher than 10°C, the daily conditions are appropriate. Feed 1%-3% of the fish's body weight and feed it 1-2 times. According to the local breeding experiments, the rice (Lian) field can be cultivated with 80-100 kg per mu, and the largest individual in the year can reach 0.75 kg. The largest individual in Xiangyun canadensis can reach 1.0 kg. Acres increased net income by 500-600 yuan, which is more than 50% higher than that of conventional breeds.
