The giant Salmonflies of the Western mountains are legendary for their proclivity to elicit consistent dry-fly action and ferocious strikes.

This species was fairly abundant in a February sample of the upper Yakima.
27" brown trout, my largest ever. It was the sub-dominant fish in its pool. After this, I hooked the bigger one, but I couldn't land it.

Why is it that some Browns have red spots and some don't? Then some have only two or three red in white or red in silver. Then others have lots of red in silver/white and just lots of red spots by them selves.
Are these sub spicies or mating seasons, different times of year, cold or warm water?
Any body know? I'm painting one on an old wooden boat paddle.

I know other fish vary considerably, too. And I'm aware of the sockeye turning almost completely red. But IMO it's not as noticable as with the red spots on a brown fish.

Welcome to the forum, Buck!

Bad luck that you didn't check out the forum a few weeks ago as there were several topics up that went into this subject at length. The short of it is that our Brownies come from two strains, the dour Scottish (Loch Leven) and a colorful German (Von Behr). The later is known for its red spots. There is also the factor that all trout tend to turn more silver and lose color in big lakes outside of spawning season.

If you are interested in more in-depth information, type "Brown trout" in the Google search up in the right hand corner (the one on the forum page not the one on your browser). This will provide a list of the extensive forum conversations on this topic.

Just like the man said different strains produce different colors. Add in the element of their surroundings and also their movements.. There you have it - different coloration patterns. Also, keep in mind their diet behaviors. That will effect their shading and how vibrant their colors are. Ohhh so much to learn eh ha?
Most of us fish our whole lives..not knowing its not the fish that we are after.

I have posted this here before, but for the full story on the diversity of the brown trout (Salmo trutta) genome, check out James Prosek's "Trout of the World" (look it up on Amazon.com, etc.). His survey (in cooperation with local experts in research) and especially paintings of the brown trout of Europe, North Africa, and west Asia will blow your mind. Look up the "cave trout" from Italy! Or the Ferox trout from Scotland...

No matter how big the one you just caught is, there's always a bigger one out there somewhere...
