Tiny Baetis mayflies are perhaps the most commonly encountered and imitated by anglers on all American trout streams due to their great abundance, widespread distribution, and trout-friendly emergence habits.
This Skwala nymph still has a couple months left to go before hatching, but it's still a good representative of its species, which was extremely abundant in my sample for a stonefly of this size. It's obvious why the Yakima is known for its Skwala hatch.

Fascinating, Stanislav. These seem to show the characteristics of the European stream trout (or Fario). Are the fish you pursue mostly wild or from stocking? Are any of these from lakes?

They are all wild. No one from lake . Look the new three pics especially the third one this fish dosn`t have a mout. All tree are from our high mountain lakes!

Very cool! I notice especially the red spots on the dorsal fin of the fish with the strange mouth. I've seen these spots on a few populations of wild browns here in PA and suspected that it might be more common in native European strains. Thank you very much.
PS--Do scuds, freshwater shrimp, crayfish, or perhaps snails comprise a significant portion of the diet in the lake where that last fish was caught?

I've seen hatchery fish with a similar deformity, but I don't know the cause. (Perhaps David has some thoughts about this.) The red on this fish is so intense that it reminds me of descriptions of the Irish "Gillaroo," which is reported to be a snail eater.

Oh c'mon, David! That was funny, and Hollywood (like lawyers) is fair game. And I had read that whirling disease could cause cranial deformities. Whatever the cause, it's kind of sad, really--it is a truly striking and beautiful fish otherwise.
