Photojournalist Soichiro Ura, who has been observing the nature of Japan for a long time, interviews leading researchers of fish ecology and river environments. In the process, he reveals that many of the common sense ideas that have been held up until now, such as "releasing fish into rivers will not increase the number of fish, and in fact will have the opposite effect," and "dams are not suitable for flood control, and will simply destroy the ecosystem," are incorrect and that we need to reconsider our approach.
This book introduces the research results of experts who can be considered the guardians of these waterfronts, as well as their valuable knowledge and proposals for the future, in an easy-to-understand manner, including concrete materials. It highlights the issues surrounding Japan's waterfronts, such as erosion control dams, estuary barrages, water transfer projects, and coastal erosion. This book will make anglers, as well as anyone who is thinking about the future of fish-friendly waterfronts, think about what they can do now.
