Blue-winged Olives
Baetis

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.

Mount Deborah and Hess Mountains. Two of the greatest peaks of the Alaska Range rise behind the braided, glacial Susitna River. These massive mountains are 35 miles north of where I took this picture.

I was not fishing, but happened to be at an unrelated social event on a hill above this tiny creek (which I never even saw) when this stonefly flew by me. I assume it came from there. Some key characteristics are tricky to follow, but process of elimination ultimately led me to Sweltsa borealis. It is reassuringly similar to this specimen posted by Bob Newell years ago. It is also so strikingly similar to this nymph from the same river system that I'm comfortable identifying that nymph from this adult. I was especially pleased with the closeup photo of four mites parasitizing this one.

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.

about two years ago i was fishing in the lower hudson valley of new york, a small streem that flows into the hudson river. it was the 2nd week of feburary when i landed a strange looking trout/salmon. she was silver whith a bright pink stripe, no spots and full of eggs,about 14"-15". on the next cast i landed a male brook trout about the same size. what kind of fish was it? do some fish change how they look in the winter months?
any ideas please let me know.
thanks, thom

I'm not totally for sure on what type of fish it is but I do know that there was a fish some people in Mexico got that had the genetics of a rainbow trout and of a steelhead trout. my best guess is that it could be a cross breed. But then again I am only guessing.

Thom, I'm stumped. I've caught some lake-dwelling rainbows that had very small indistinct spots, but I've never seen a rainbow without spots (except for those yellow cartoon rainbows that states like PA use as stocking "indicators"). Then again, if the fish swam up from the Hudson, who knows? Maybe it passed under the outfall pipe of a carbon tetrachloride plant and had its spots removed! :) (Sorry, but I couldn't resist. Both of the fish you describe certainly qualify as pretty unusual specimens, especially for a lower Hudson trib in February.)
