Sanming is located in the northwest mountainous areas of Fujian Province, some years ago, large and medium-sized waters and rice paddy fish farming has been fully developed, aquatic products production increased rapidly. Production went up, but due to the breeding structure is not reasonable, single species, there is a breeding industry to increase production without increasing income. People realize that the adjustment and optimization of fishery structure is imperative.
In 2000, the introduction of rainbow trout in Sanming City, Jiangle County, trial farming, the initial success, to find and summarize a set of farming techniques. This useful attempt to cause the Sanming Municipal Party Committee and the municipal government to pay close attention to the relevant leaders many times in-depth rainbow trout breeding points to understand the situation, and coordinate to solve the rainbow trout breeding in the land, water, electricity and other issues. Last May, the municipal government held a special by the county and district governments in charge of the leadership, animal husbandry and fisheries bureau director to participate in the scene, on a large scale, industrial development of rainbow trout aquaculture processing planning and deployment.
According to experts, natural rainbow trout live in cold areas abroad, basically no distribution within our country. Our country from the 1950s onwards in the northern areas of trial farming, only after 1985 from the United States to introduce Road Nelson rainbow trout for commercial farming. In the south of the rainbow trout farming is a new subject, due to the rainbow trout on the breeding conditions and breeding technology requirements of harsh, requiring owners to have a certain degree of economic strength, but also technical security, blind development shall not. In order to serve the farmers, the City Bureau of Animal Husbandry and Aquatic Resources organized aquatic technology cadres in-depth grass-roots, guiding the owners of the conditions in time to adjust the breeding structure, to rainbow trout. At the same time, specifically set up by the senior engineer as the leader of the rainbow trout farming technology service group, to carry out farming technology research, training of farming professionals, to provide technical services. It also invested 500,000 yuan to build a rainbow trout seed farm, and built aseptic hatcheries, nursery pools, cultivation pools and supporting facilities to ensure the supply of high-quality seedlings. Perfect service to promote the rapid development of the city's rainbow trout aquaculture industry, Sanming City has formed a mountain streams and streams, underground cold spring water farming and citing the reservoir drainage culture three breeding modes, built 17 rainbow trout breeding sites, breeding area of 5,000 square meters, more than 400,000 fry, production of 200 tons of commercial fish, and the New Year's Day, the Spring Festival period of the market one after another.
Evening of the Spring Festival, Sanming City, held in the provincial capital of Fuzhou, rainbow trout promotion tasting, attracted the attention of the press and catering industry. At the meeting, Yang Songdong, deputy director of the city's Bureau of Animal Husbandry and Fisheries, said there are 71 breeding sites in Sanming City available for the development of cold-water fish, with an area of 170 acres and a capacity of 4 million rainbow trout. He said that Sanming City will continue to utilize alpine mountain stream water and cold spring water resources to vigorously develop the breeding of rainbow trout and other cold-water fish, and establish a southern cold-water fish breeding base in Sanming by further improving the seed breeding system, disease prevention and control system, technical service system and product processing and marketing system, and by researching and promoting the breeding of new technologies and new modes. 1 million rainbow trout will be farmed in 2003 to produce 500 tons of adults, while developing the breeding of Pacific trout, which has a capacity of 4 million tail. In 2003, the company will raise 1 million rainbow trout and produce 500 tons of adult fish, and at the same time, it will develop the culture of Pacific salmon, sturgeon and other cold-water fish.
