Shandong Province Key Research and Development Project and Qingdao Key Technology Research and Industrialization Demonstration Project in Qicai Seed through the phased acceptance of results
On May 30, 2024, Ocean University of China organized relevant experts to conduct research on the key R&D Plan (Major scientific and Technological Innovation project) of Shandong Province in Laixi Park of Qingdao Qicai Seed Technology Co., LTD. "Development and application of key technologies for Excellent germplasm creation and large-scale seed cultivation of cultured fish in Important Facilities" And Qingdao key technology research and industrialization demonstration project "large-scale salmon large-size seed circulating aquaculture technology development" stage results carried out on-site acceptance.
Bao Zhenmin, academician of the Chinese Academy of Engineering and professor of Ocean University of China, attended the acceptance meeting as the person in charge of the key research and development plan (major scientific and technological innovation project) in Shandong Province. Wang Qingyin, former director of the Yellow Sea Fisheries Research Institute of the Chinese Academy of Fishery Sciences, was the group leader. The meeting was chaired by Gong Qingli, professor of Ocean University of China and chairman of Qingdao Qicai Seed Technology Co., LTD.
项目组工作汇报 At the meeting, Professor Gong Qingli made a special report on "Collection of salmon-trout germplasm resources, production performance testing and pilot demonstration", "Breeding and artificial breeding of Murray cod" and "Development of circulating aquaculture technology for large-scale salmon seedlings", and introduced in detail the species characteristics, breeding and breeding status of salmon, rainbow trout, king salmon, coho salmon and Murray cod, and the problems that exist. Professor Gong pointed out that Ocean University of China (hereinafter referred to as "OUC") and Qingdao Qicai Seed Technology Co., LTD. (hereinafter referred to as "Qicai Seed") jointly collect, introduce and preserve excellent germplasm resources, build live germplasm resources bank, and establish a technical system of large-scale expansion and propagation of seedlings. Breakthroughs have been made in the cultivation of high quality germplasm resources of Murray cod and in the introduction and cultivation of salmon and the circulating water culture technology of large-size seedlings. In recent years, China's salmon sales continue to rise, which is expected to reach 300,000 to 400,000 tons/year in 2030. Shandong Province vigorously develops Far-reaching Marine aquaculture, and salmon is the most potential species of Offshore Deep-sea and Far-reaching Marine aquaculture in Qingdao. The supply of large-scale salmon seedlings is one of the most important problems to be solved in the development of Far-reaching Marine salmon aquaculture. The smooth implementation of this project will further promote the development of the whole industrial chain of 100 billion scale salmon industry in China. From 2023 to 2024, OUC scientific research team, together with Qicai Seed introduce 6 batches of salmon-trout hair eggs from Iceland, Denmark, Spain and other countries, collection of Atlantic salmon, rainbow trout, king salmon and coho salmon germplasm resource groups, the establishment of living germplasm bank, the current hatching and breeding progress is smooth, hatching rate and survival rate are higher than 95%. At the same time, the scientific research team has carried out artificial induction of the Atlantic salmon pseudopanax breeding work, the induction rate of 100%, will further use the Atlantic salmon pseudopanax artificial breeding work, aimed at fundamentally solving the seed industry "stuck neck" problem. In the field of Murray cod breeding technology, after years of technical accumulation, Qicai seed industry has broken through the large-scale artificial breeding technology of Murray cod, and has now selected and bred nearly 7,000 high-quality Murray cod parents, with more than 10 million fertilized eggs and more than 6 million newly hatched larvae by 2024.
The members of the expert group listened carefully to the report of the project team, inspected the breeding site, and conducted on-site sampling of salmon fry and Murray cod parents and fry, measured body length and weight, observed the health status of fry, and conducted data statistics. The expert group agreed that the collection of salmon germplasm resources and the construction of living germplasm resources bank are of great significance, and are the important way to break through the "stuck neck" problem of salmon artificial breeding and realize the technological autonomy and control of the whole salmon industry chain. 验收组组长 中国水产科学研究院黄海水产研究所原所长王清印研究员 验收组成员 中国水产科学研究院黄海水产研究所田永胜研究员 山东省海洋科学研究院王继业研究员
