Current situation analysis and development suggestions of the Apostichopus japonicus culture industry in Shandong Province.

In the 1980s, Shandong Province took the lead in establishing breakthrough industrialized seedling raising and breeding technologies for Apostichopus japonicus and successfully led the 'fifth wave of mariculture' in China. In 2008, the experiment of 'raising sea cucumber from north to south' proved successful, and sea cucumber culture gradually radiated and extended to Fujian, Jiangsu, Guangdong, and Zhejiang Provinces in southern China. The total output of sea cucumber culture in Shandong Province accounts for more than 70% of the market in China, and the sea cucumber industry is now a pillar of the fishery economy in Shandong Province. This paper systematically introduces the development status of the sea cucumber breeding industry in Shandong Province in recent ten years, summarizes the current problems and challenges, and puts forwards development suggestions; this guidance has significance for the healthy and sustainable development of the sea cucumber breeding industry in both Shandong Province and the whole country.
