Spotted earthworm is a triploid carp that was developed by artificial breeding of Atlantic salmon and rainbow trout. The tail water is the main source of fish in North America, mainly in North America, Norway, Sweden, Finland and other countries. Also a lot of culture. The fish is delicate, unique in taste, high in nutritional value, and tastes better than salmon. In addition, it also has a unique medicinal health care value, containing glycine, which is not found in fish in general, and vitamins A, B, and iron are significantly higher than other fish and can effectively prevent cardiovascular and cerebrovascular diseases.
In 2010, the Shandong Institute of Seawater introduced 100,000 spotted eyeballs from the United States and successfully cultivated 89,000 healthy seeds of more than 8 centimeters. In 2011, 700,000 pieces of spotted eggs were introduced. At present, 6 million to 8 centimeters of seedlings have been cultivated. After more than a year of painstaking research and hard work, it has overcome the difficulties of breeding seedlings and spotted the breeding techniques of spotted earthworms. Spotted earthworms are particularly suitable for breeding in northern China, and are resistant to low temperatures. When the water temperature is 6°C to 8°C, they can feed normally, and they are still active at 2°C～3°C. In winter, it is possible to naturally overwinter in the culture cages, and in the summer, the deepwater cages can achieve a safe summer, which can greatly increase the utilization efficiency of the northern culture cages and solve the problem of the current idle waste of many cages in the north. The spotted cockroach is also suitable for the current type of industrialized aquaculture model in China. The current aquaculture facilities can be cultured without modification, which greatly saves the cost of culture.
The leaders of Shandong Science and Technology Department, Shandong Ocean and Fisheries Department and Qingdao National Marine Scientific Research Center made important speeches and agreed that they must seize the historical opportunity for the construction of the blue economic zone in Shandong Peninsula, establish brand awareness, and use Molding branded fish forms new economic growth points in Shandong and northern coastal areas of China. Participants from the Penglai Jinglu Fishery Co., Ltd., Qingdao Fuka Biotech Co., Ltd., and Qingdao Zhonghai Aquaculture Co., Ltd. attended the meeting.
