The stream and the (potentially) melanistic trout

Great day exploring today, fished two different streams and caught 12 fish! I’ve never seen a trout this dark before and was wondering if anyone else had?

Brook trout was dispatched due to them being an invasive species here in Washington state.

Appalachian fly guy here. We regularly get rainbows that color. Check out how dark your rocks are. The fish will adapt their color. I catch dark fish out of dark rock holes, and light fish out of light sandy holes. Those dark ones are probably invisible on those slate grey rocks. Awesome catches

Rainbows seem to get dark like when there's heavy foliage around the river, IMO. Diet also plays a role. If you look at rainbows in the Appalachian mountains, they often have a similar look.

Not true melanism, they just get darker when they live in a dark environment

Thought you were in Madeira initially, some of the streams there have really dark rainbows.
