June 5, 2020 is the 49th World Environment Day, with the theme of caring for nature without delay, focusing on biodiversity. There are many anglers in Yanziji and Xiaguan of Nanjing City, many of whom operate throwing poles and use string hooks and row hooks for fishing. The normal single rod anglers are only a few. Most of the anglers are aware of the national fishery policy's advocacy of one rod for one person, one rod for one hook, but there is a widespread awareness that fishing will not damage the ecological environment. Shan Pingji, vice president of the law school and director of the civil procuratorial research base of the Supreme People's Procuratorate, was invited to interview Jiangsu TV station on the legal regulation of fishing and the protection of fishery resources.

In order to better protect biodiversity and fishery resources, associate professor Shan Pingji, in combination with the policy of ten-year ban on fishing and relevant legislation, suggested to distinguish productive fishing and recreational fishing, and to make more detailed provisions on fishing gear, fish and the areas and time periods allowed for fishing. In order to better protect the ecological balance and regulate the current fishing chaos, the fishing license system can be considered when necessary To guide the public to enjoy healthy fish.
