America Is Releasing Fish That Hurt Its Own Rivers

Added: 2026-06-02

[00:00:00]Most people think rivers in America are naturally full of fish, but that's not always true anymore. So, across the US, states actually raise millions of fish in hatcheries just to release them into rivers and lakes for people to catch.

[00:00:12]And here's the crazy part, a lot of those fish aren't even native to America's waters. Some trout species were brought from Europe and other parts of the world over 100 years ago. The problem is, those fish can outcompete native species, mess with ecosystems, and even change the genetics of local fish populations. But states still keep doing it because fishing licenses and gear taxes bring in massive money for conservation. So, now there's this weird paradox in America. To fund conservation, they sometimes end up hurting the very ecosystems they're trying to protect. And most people fishing out there have absolutely no idea.
