1. Selection and breeding of improved varieties. Gao Chun has successively organized and implemented provincial science and technology research and development projects such as large-scale cultivation technology development of large-scale mitten crab species in the Yangtze River system, and established a national-level Gucheng Lake Yangtze River system Chinese mitten crab original seed farm and seed selection technology line. It was recognized by the expert group of the Institute of Geography and Limnology, Chinese Academy of Sciences. After selecting the original parents and sending them to coastal breeding bases, advanced seedling technology is used to breed high-quality second-generation big-eyed larvae, ensuring the original source of Gucheng Lake crabs. The government has invested more than 10,000 yuan to establish a county-level crab seedling cultivation center, guiding and driving the county's seedling cultivation area to reach 1,000,000 acres, with an annual supply of 10 million high-quality crabs, and the county's high-quality crab seedling supply rate reaching 10%. 2. 2. Ecological breeding. Gaochun adheres to the principles of ecological, efficient and safe breeding, and formulates scientific breeding models according to different water conditions. Crab seedlings are artificially released in the lake to increase resources and produce high-quality ecological crabs. Reasonable stocking is adopted in river ditches, aquatic plants are transplanted, and snails are put in. To produce pollution-free commercial crabs, moderate sparse stocking, grass cultivation, and scientific interbreeding are adopted in crab ponds to produce green products. Organic crab. Focusing on innovative breeding models, we have explored and developed simulated ecological breeding methods such as diversified aquatic plant planting, self-breeding of snails and lions, and micropore oxygenation. Through the purification of snails and the absorption of aquatic plants, we can maintain an excellent ecological environment for crab growth. Therefore, Gucheng Lake crab is a truly green pollution-free product and a famous brand product.
