Abstract: Aquatic seed industry is the cornerstone of the development of aquaculture.Promoting the construction of commercial seed breeding system can solve the prominent problem of the separation between scientific research and market in the traditional breeding system.In order to further promote the development of aquatic commercial breeding,this paper analyzed the development status and shortcomings of China's aquatic seed industry enterprises through literature query,data statistics and case comparison.It was considered that the development momentum of China's aquatic seed industry enterprises was good,which was reflected in the improvement of enterprise breeding awareness,the effective application of seed conservation and control technology,and the diversity of commercial breeding forms.At the same time,China's aquatic seed industry enterprises also had problems such as weak enterprise competitiveness,development potential and risk resistance,which were reflected in weak independent innovation ability,less investment in breeding R & D,small enterprise scale and so on.In this regard,we proposed to further enhance the competitiveness of China's aquatic seed industry and promote the commercial development of aquatic breeding by formulating breeding innovation strategies from the two aspects of breeding objects and breeding process,extending vertically and broadening the seed industry chain horizontally.
