World Rivers Day, this year on 24 September, is a celebration of the world’s waterways. It highlights the many values of rivers, strives to increase public awareness, and encourages the improved stewardship of rivers around the world.

To further explore the related research on World Rivers Day 2023, we have gathered open access academic articles on the topic of fishes in rivers. On this special day, we hope to share interesting and up-to-date scientific knowledge in this field.
