Why
Human-made alterations to rivers (dams, hydropower, climate change) are driving rapid evolution in fish, which in turn reshapes river systems and challenges conventional management strategies.
The Frontline Impact

How this affects you

The research suggests that fish evolution is not merely a conservation issue but a critical water management concern, as evolutionary changes in fish populations can alter riverbed structure, water flow, and flood risk, necessitating a fundamental rethink of river restoration and infrastructure design.
