As lakes turn brown, trout and bass decline while pike and walleye thrive
Key takeaways
- The lakes, streams and ponds you ve visited for years are likely looking more brown than they used to.
- Our research has identified a link between those two developments, which means that trout, bass, perch and whitefish may become less common in unstocked lakes.
- In the past several decades, across much of northeastern North America and northern Europe, many freshwater ecosystems are getting darker, and they are changing in other ways as a result.
Why this matters: new research or scientific developments with potential real-world impact.
The lakes, streams and ponds you ve visited for years are likely looking more brown than they used to. And people who are fishing those waters are likely catching different species and sizes of fish than in the past.
Our research has identified a link between those two developments, which means that trout, bass, perch and whitefish may become less common in unstocked lakes. But pike and walleye anglers may be in for a trophy-sized surprise.
In the past several decades, across much of northeastern North America and northern Europe, many freshwater ecosystems are getting darker, and they are changing in other ways as a result.
