Fish Migration from Sea to Source

Migratory fish are in trouble

At least half of all the flow in the world’s rivers is manipulated or fragmented, and the wild free flowing rivers are now more threatened than ever. Only 64 of the 177 rivers, longer than 1,000 km, are free-flowing and yet there are plans to build more than 3,500 new large dams in Asia, Africa and South America.

Migratory fish and river ecosystems need our help: dam removal, fish passages, river restoration, wetland and forest protection, and so on.

Learn more about migratory fish, rivers and what you can do from the book “From Sea to Source 2.0“!

You can download a free PDF version of the book from here: From Sea to Source 2.0

Here are the cartoons I made for the book.
