An analysis on development strategy of bluefin tuna aquaculture in Japan and its enlightenment to China

【Objective】To learn from the experience of Japan bluefin tuna aquaculture industry，which could prowide reference for promoting the development of bluefin tuna aquaculture in China，strengthening the supply capacity of China’s high-value aquatic products and formulating relevant incentive policies.【Method】This paper combed supply and demand of bluefin tuna in the world，analyzed the internal causes and specific paths of Japan’s leading role in bluefin tuna marketing，and used strategic research methods to clarify the series of research and development measures taken by Japan to promote development of the industry.【Result】Japan is one of the major tuna breeding bases in the world，and it is one of the earliest countries to develop bluefin tuna breeding technology. In 2022，Japan had 88 business entities，187 farms，and 1379 breeding cages，with an annual output of 21460 t. Through strategies such as output system，technological innovation，seed industry improvement，and export to China，Japan has led the global supply and demand docking of the industry，enhanced the international discourse power of Japanese bluefin tuna，and promoted the revitalization of coastal fishing villages. During the“Fourteenth Five-Year Plan”period，the bluefin tuna industry is positioned as a strategic emerging industry. China has been systematically building a new business model for the entire tuna industry chain. The Chinese Academy of Fishery Sciences has been actively expanding the deep and distant sea aquaculture space，and has accumulated certain experience in yellow fin tuna aquaculture. At the same time，it has been fully promoting the development of bluefin tuna aquaculture. In recent years，breakthroughs have been made in tuna aquaculture in the South China Sea.【Suggestion】In Hainan，Guangdong，Zhejiang and other existing national marine ranch demonstration areas， China has taken advantages of existing technology and waters where bluefin tuna live to promote the development of Bluefin tuna. China should further increase international cooperation and exchange in scientific and technological innovation，and promote China and Japan to jointly develop the consumer market for bluefin tuna. Establish a sound management system that is compatible with international fisheries management rules，optimize regulations and policy measures for the management of bluefin tuna and draw up relevant policies to support the industry development.
