The article highlights the significant decline in Japanese eel catches, attributed to environmental factors and habitat destruction, which has reduced the industry to less than 10% of its peak. To sustain the industry, there is a push for commercial mass production of artificially bred eels and the implementation of traceability systems to reduce overfishing. The challenge lies in improving the quality of artificially bred eels to match wild ones, necessitating research into feed and breeding techniques. Additionally, the article touches on the need for resource protection and sustainable management practices, including the legal framework for eel fry fishing and efforts to combat illegal trading. Taiwan is experimenting with traceability systems and app trials to support these initiatives.
