According to the characteristics of stable genetic traits and particularly fast growth rate of Aeoliana, the corresponding breeding techniques were summarized through extensive mass production. It includes breeding, seed breeding, adult fish farming, cage culture, paddy field farming, transportation and seed selection. Among them, there have been innovations and developments in breeding, large-scale summer fish species intensifying cultivation, raising fish in the past, high yield of pond main breeding, and breeding in one year. I. Jianye and its production performance (1) The origin of Jianye is to use the specific purse red peony and Yuanjiang yin as the parents, and to design and adopt a combination of pedigree breeding, interline hybridization and gynogenetic development. Breeding new techniques, new technologies, and breeding for the first time in China. (II) In addition to the advantages and production performance of hybrid carp, Jianye's production performance Jianzhu has the following outstanding features compared with hybrid carp and other carp: (1) Jianmao is a fast-growing species and its growth rate Obviously faster than various hybrids and other carp. (2) Jian’an has a moderately long body shape while maintaining the advantage of higher and wider body, which is different from the existing various hybrids. (3) Jianou meat has good taste and high nutrient content. (4) The disease resistance and adaptability of Jianye are strong. Under the various farming methods in the 30 provinces, municipalities, and autonomous regions that have been promoted, the growth conditions are good. (5) The genetic character of A. cristata is stable, self-cultivation and self-cultivation are not required, and hybrid seed production is not required, which can reduce costs, save labor and equipment, and facilitate promotion. 2. Fish Breeding 1. The cultivation of large-scale summer fish species The cultivation of large-size summer fish species refers to the cultivation of oyster fish seedlings after being cultivated into pufferfish species, and then immediately dilute them in ponds and raise them quickly for about 15 to 20 days. The process of becoming a 5-6 cm large-scale fish species. In terms of time, it is similar to the cultivation of ordinary summer flower species, but it is only a matter of time. Large-size summer fish species can be immediately used for ponds, cages, fences and other kinds of adult fish culture, when they can develop commercial fish. (1) Selection and clearing of fish ponds. Basically the same with the fry pool, the area of ​​2-3 acres is appropriate, water depth of 1-1.5 meters. Before use, it must be carefully cleaned and thoroughly disinfected. (2) Base fertilizer. In the first 5 to 7 days of stocking fish species, 300 to 400 kg of manure per acre, 240 kg of green manure, or 250 kg of livestock manure, 30 kg of green manure and 5.5 kg of quicklime are used to compost mixed compost. (3) Fish stocking. Fish species are stocked as early as possible to prolong the growth period of the species. Stocking densities range from 6000 to 8,000 per acre. Single-cultivation Jianye generally does not mix other fish. Fish species should be robust and have neat specifications. (4) Feeding management. After Wucai Down Pond, due to the small fish body, it still needs to feed a few days of soybean milk. Soymilk was splashed and Soybean Pond was fed poolside and fed twice a day. A few days later, the bean curd paste was changed, and about 3-4 kg per 10,000 fish were placed in a fixed position near the pool. In the breeding process, fish species also need to feed large amounts of natural zooplankton and benthos and other natural foods. Therefore, the water quality must maintain a certain degree of fatness. In addition to Shiji Fei, but also according to the appropriate conditions of water quality fertilizer, each quantity should not be too much. To adhere to the morning and evening patrol ponds, the precautions are the same as the fry rearing. 2. Cultivation of one-year-old fish species (1) Stocking of fish species. The cultivation of Jianye first-year fingerlings is to cultivate summer fish species (about 3 cm), and after the ponds are divided, they are stocked with about 10,000 fishes per acre and cultivated into winter or spring fish. Mixed cultures can also be used to build the main summer flowers, mixed fish, grasshoppers, earthworms and other fish species. Each mu can be stocked with 6,000 to 7,000 tails, and grass, cockroaches, and squid are 3000 to 4000 tails. In a fish farm, from 1988 to 1989, 6,000 species of summer fish were reared on a per mu basis in a fingerling pond, and 5,000 species of grass and blue fish were reared. After six months of breeding, the average weight of each end was approximately 50 grams. With a yield of 300 kilograms per mu, the yield of pond species per mu reached 611 kilograms. (2) Feeding management. The specifications of the first-year fish breeding ponds should be 3-5 mu and the water depth should be 1.5-2 meters. Clearance and disinfection of fish ponds, basal fertilization, top dressing and other management measures are the same as the cultivation of fry and the cultivation of large-size summer fish species. However, due to the continuous growth of fish, it is more important to feed sufficient feed and maintain good water quality. This phase lasted for several months and experienced many seasonal climate changes to prevent flooding and other accidents. It is also very important. Jianou is an omnivorous fish. In addition to feeding concentrate, the leaves and benthic organisms are all foods that they like to eat. Casting Chasha often, the effect is also very good. Before the big heat, the fish grows faster. It is necessary to feed more food and feed more bean cakes and cakes to enhance the body. (3) Overwintering ponds. In the late autumn and early winter, when the water temperature drops to about 10, the fish have stopped or rarely eaten. To facilitate management, the ponds should be pooled and the fish should be kept in winter in the fertilizer ponds. To strengthen the cultivation in the autumn, to feed more concentrate feed and enhance the fish's constitution is the inherent material basis for ensuring the safety of fish species. During the winter winter season, in the southern part of China, when the weather is clear and the water temperature is high, if Jianou still eats, it is appropriate to put some concentrated feed. In northern regions, winter temperatures are low, and in some places, the ice-sealing period lasts several months. The thickness of the ice layer is several tens of centimeters. It attaches great importance to the management during the winter and takes ice-breaking and aeration measures to prevent the suffocation of fish species. This is especially important. (4) Identification of fish quality. Generally observed with the naked eye. A look at the appearance of fingerlings, such as strong body fat, scales intact without damage, bright body color, neat specifications, is a good quality fish species; Second, watch the fish activities, such as fish swim agile and lively, strong anti-water , In the cages often intensive upwind at the top, it is good quality fish species, especially in the bottom of the fish species is better. III. Cultivation of adult fish in ponds in Jianou (1) Aquaculture in fish ponds 1. The pond area in ponds should be 5-10 mu, and the maximum should not exceed 100 mu. The pond that the main grazing land should build should be below 5 mu with a water depth of 2 to 2.5 meters. The water source should be sufficient and the water quality should be good. Clay and loam soils are preferred for soils, and the ponds must be solid, do not leak water, do not collapse, and should be cleaned and disinfected before stocking. 2. Species, size, and quantity of fingerling stocks for stocking, rearing, and rearing of fish species should be determined by the expected indicators of adult fish yield, the size of commercial fish, and the actual conditions of ponds and production. Early stocking of fish species is one of the important measures for production. Fish are generally stocked in winter or early spring. Summer fish species were stocked in May and June. The fish stocks to be stocked should be divided separately, and the requirements for stocking at the same pond should be the same variety, the specifications should be neat, and the foot should be enough at one time. Jianou in the production of adult fish, in southern China is generally used as a breeding breed. Therefore, the proportion of its stocking should be subordinate to the main fish. Its growth and production are affected not only by other fish in the pond but also by the density and specification of the species. (1) In the high-yield ponds of adult fish, mainly squid, ponds with rich fertilizer sources, relatively high water quality, or the use of domestic sewage can raise squid. The proportion of stocking is roughly: 60% for carp, 10% for carp, 10% for grass carp, 10% for carp and carp, and 10% for carp. (2) Grass-fish-based high-yielding adult fish ponds may be mainly grass carp, where there are abundant water resources, rich grasses, and dry grass resources, or grass carp pellet feeds are low in price and source sufficient. Grass carp and head lice account for 60%, carp 25%, carp 5%, and Jianou 10%. (3) In the high-yielding ponds for adult fish, which are mainly cultivated with herring, close to the Great Lakes and areas rich in snails, fish are the main breeding objects. However, carp and herring eat the same feed and there is a certain contradiction between the two. Therefore, in the pond where the main herring is raised, the stocking size of the herring should be smaller, preferably 11.6-13.2 cm, and the quantity should not be much. In the case of the above-mentioned mixed fish-based polyculture, feeding and management are mainly to take care of the main fish, taking into account the other polyculture fish species, and Jianye adaptability, food habits and miscellaneous, no special management Measures. (4) In the high-yielding ponds of adult fish that rely on Jianye, the stocking amount of Jian'ou accounted for about 60% to 70% of the total stocking amount. (2) The pool of fingerlings in the pool of fingerlings in the fingerling pool refers to the amount of the cultivated fish in the flesh of the summer fish in the family. The fingerling of the fingerling of the fish is required to reach 9.9-13.2 centimeters before the end of the year. Commercial fish species specifications of a farming method. Fish breeding ponds are raised, and the stocking density, specifications, and feeding and management of the fish species are routinely conducted. In other words, to fully utilize the role of Jian’an to clean the food farm without affecting the production of fish species in the domestic fish and increasing the investment in feed management, and to increase the yield of some adult fish by using residual baits and benthic organisms at the bottom of the pool. And earnings. 1. The stocking of home-breeding fish species is cultivating fish species, and some polyculture, some monoculture, and polyculture are favorable. Bile-concrete culture species are not as large as adult fish breeding, and generally two or three species of fish are polycultured. Stocking densities are: 6000-10000 tails of summer fishes in general. 2. Jianye's self-cultivation is another stocking object for stocking after the above-mentioned fish are stocked. Kenai's stocking specifications are about 3 cm, and the specifications of the fish species are more than 2 cm. The stocking densities of A. sinensis should be based on the conditions of the fish ponds, feeding and management conditions, and the density and specifications of the fish species of the fish. In the case of the stocking of the above-mentioned fish species, the stocking densities of Aconia are between 30 and 100 tails per acre, all of which can reach the commercial specifications. If the density is dilute, the individual grows large and has a large density and grows small. (C) Two-year-old fish breeding Since Jianou is a fast-growing variety, the growth rate is particularly fast, so it is possible to cultivate fish two years later. This technology has been tested and popularized in Beijing, Tianjin, and other places, and the effect is very good. The main technical points are: After the cultivating and diluting cultivation of Wuzai into a large-scale summer fish species, the stocks will be stocked and raised and managed according to the requirement of the fish owners to cultivate fish in the current year. By the end of the year, most of the fish can be listed. Fish that cannot be listed will be stocked early after winter and will be available in June. This will not only make full use of the free time of fish ponds in June, but also provide fresh fish for the market during the off season of May and June. Relatively high.
