Hex Mayflies
Hexagenia limbata

The famous nocturnal Hex hatch of the Midwest (and a few other lucky locations) stirs to the surface mythically large brown trout that only touch streamers for the rest of the year.

Two major forks of this grayling stream come together in this pretty pool.

This is the first of it's family I've seen, collected from a tiny, fishless stream in the Cascades. The three species of this genus all live in the Northwest and are predators that primarily eat stonefly nymphs Merritt R.W., Cummins, K.W., and Berg, M.B. (2019).

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.

The presentation I saw tonight by artist Ray Troll introduced me to a really cool extinct salmonid: Smilodonichthys, the Saber-Toothed Salmon. It was an anadromous fish found in the Pacific from LA north at least to Canada, and it grew up to 10 feet long and 500 pounds, averaging more than half that. It had two enormous teeth giving it the saber-toothed look, but otherwise most resembled a gigantic sockeye salmon.

We missed this amazing fishing opportunity by a mere 4-5 million years. Can you imagine the crowds that would line the Kenai for a shot at one of those?

Ray's paintings of the extinct species are awesome, as are the photos of the fossils. Unfortunately I can't find any of them online. If anybody can, be sure to post the link!

Be glad to help you out. A collection of fossils were found in the Skykomish River not far from my cottage. A fisherman found it from the local tribe. 100 in total.

There are other sources.

One now extinct salmonid from this era is the saber-toothed salmon. Weighing hundreds of pounds, it had a pair of enormous curved teeth, but fed chiefly on ...

This should take you to the jawbones they found as well. Huge fish.
