Migratory Fish Populations Have Dropped 76% Since 1970

A new report on migratory freshwater fish was released last month. The opening comment in the press release states that “With hydropower, overfishing, climate change and pollution on the rise, monitored populations of migratory freshwater fish species have plummeted by 76% on average since 1970.”


The Living Planet Index for Migratory Freshwater Fish

The Living Planet Index for Migratory Freshwater Fish is the first comprehensive global report on the status of migratory fish. The technical report finds migratory freshwater fish are under immense threat from human-made impacts and urgent action is required to halt and then reverse the alarming decline.

“The statistics are shocking but we know migratory fish populations can bounce back. We need to act now before populations get to the point where they are too low to recover. Now is the time to value migratory fish and the rivers that sustain them.” – Herman Wanningen, Founder of the World Fish Migration Foundation.

It is abundantly that circumstances are at a tipping point.  The report states  that further work and research are needed on the global status and trends of migratory fish, especially given their economic, environmental, cultural, and recreational importance around the world. Additionally, more research and trials on effective management strategies are needed to protect populations around the globe. The collaborators on this report hope that these findings will encourage countries to prioritize freshwater protections and effective management strategies.

  1. How do humans harm the planet? Let me count the ways. Oh that’s right, I can’t, there are far too many ways to count!
