Analysis of the problems existing in the development of the eel industry and the countermeasures and suggestions
I. Seedlings and fingerlings The main species farmed for eel in China are the Japanese eel (Anguilla japonica) and the European eel (Anguilla anguilla). The resources of both the European eel... have already approached exhaustion, with annual production falling from 3,000 tons 30 years ago to 100-200 tons. From June 3 to 15, 2007, at the Conference of the Parties to the "Washington Convention" (CITES) held in the Netherlands, the European eel was listed in Appendix II of the Convention on Endangered Species of Wild Fauna and Flora, and this will be formally implemented starting in January 2009: China imports about 60 tons, or about 150 million individuals, of European eel seedlings and fingerlings annually, and farmed European eel accounts for more than 1/3 of eel production, while European eel accounts for about 40% of exported roasted eel. Japanese eel resources have also severely declined. In recent years, the seedling and fingerling resources of Japanese eel in Asia have remained at about 100 tons, and the annual catch in recent years has remained at 80-100 tons. In 2008, the output of European eel seedlings and fingerlings was about 90 tons, half of a normal year. The output of Japanese eel seedlings and fingerlings was about 35 tons, one third of a normal year. The severe shortage of seedling and fingerling resources has led to soaring prices. Moreover, artificial breeding of eel seedlings and fingerlings will not be able to form production capacity in the near future.
