In Jiangsu, there are 2,588 species of freshwater creatures, an increase of 51 species compared with 2022. The number of fish varieties and Yangtze finless porpoise in the Jiangsu section of the Yangtze River has increased significantly due to the comprehensive protection of the river and the implementation of the "10-year fishing ban." Notably, rare and endangered species such as Chinese sturgeon and Chinese high-fin banded shark have been recorded and discovered in the survey.
