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.

This one seems to tentatively key to Holocentropus, although I can't make out the anal spines in Couplet 7 of the Key to Genera of Polycentropodidae Larvae nor the dark bands in Couplet 4 of the Key to Genera of Polycentropodidae Larvae, making me wonder if I went wrong somewhere in keying it out. I don't see where that could have happened, though. It might also be that it's a very immature larva and doesn't possess all the identifying characteristics in the key yet. If Holocentropus is correct, then Holocentropus flavus and Holocentropus interruptus are the two likely possibilities based on range, but I was not able to find a description of their larvae.
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.

A couple years ago I heard my buddy saying to another, that he can smell the fish in the water. This came from a conversation about steelhead and salmon. I'm thinking to myself, all the spawn in the river during those times, maybe.

I went to my local steelhead water about a month ago, no fish caught, no smell. I went yesterday and the stream smelled fishy. I caught a medium brown and saw a few minnows.

What's up?

The only time I've smelled fish in the water is when salmon carcasses are all over the place. But then again, my nose is more attuned to sniffing out a good cup of coffee or a wee dram of...:)

I can't say for sure with salmonids -except for the dead ones. Might be though as I've smelled largemouth bass on stillwaters -an odor something like fresh cut grass. I wonder though, whether I smell the fish, or catch the fish, first (lol).

I can't smell fish on a river unless their, like it has been stated, dead.. Now after i catch a few i can certainly smell that river from a mile away!
Most of us fish our whole lives..not knowing its not the fish that we are after.
