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.

As far as I can tell, this species has only previously been reported from one site in Oregon along the Columbia gorge. However, the key characteristics are fairly unmistakable in all except for one minor detail:
— 4 small yellow spots on frons visible in photos
— Narrow occipital spinule row curves forward (but doesn’t quite meet on stem of ecdysial suture, as it's supposed to in this species)
— Short spinules on anterior margin of front legs
— Short rposterior row of blunt spinules on abdominal tergae, rather than elongated spinules dorsally
I caught several of these mature nymphs in the fishless, tiny headwaters of a creek high in the Wenatchee Mountains.
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.

Hi all, I'm new to the board, and am interested in everyone's opinion on something. Does everyone believe that typical trout tactic's work on Land Lock's? I've heard some people say that They act and feed just like trout, and others say that you will only catch them on streamers. I have my own opinion, but am wondering what everyone else thinks.
Thanks, Dave

Dave,

As with most things, I'd have to say that it all depends. What landlocks are you referring to and what time of year are you fishing for them?

I've never caught Atlantics on anything other than streamers and then only at certain times of year when they were following baitfish into streams.

In the western U.S. I've caught lots of Kokanee--landlocked sockeye--using more traditional trout tactics but only on nymphs and not on dry flies and only in streams when they were beginning their spawning runs.

I suspect it has more to do with the feeding preferences of the ancestral stock--fish eating vs. plankton feeding, etc.--than anything else. I've never tried to catch either when they were in the open water of a lake, but I suppose that they might well eat flies. It's just that in my experience they tend to hold a little deep for fly fishing to be much fun.

Dave,

Earl's "it all depends" answer is about all that can be said without knowing more about the landlocks (Atlantics, I assume) you're trying to catch. However, just about any type of fly that catches trout can catch landlocks in certain situations.

Stream resident landlocks can be very troutlike--feeding on mayfly and caddisfly hatches and responding well to nymphs, wets, and drys. Even in lakes, strong Hex or brown drake hatches or some of the lake caddisflies can bring them eagerly to the surface. The landlocks of the Finger Lakes can often be caught with nymphs and dries during such hatches, and I'm sure a similar situation exists in many other Northeastern lakes.

Of course, streamers are classic landlock fare. Whenever landlocks forage on baitfish like smelt or alewives, and especially when they are following the spawning runs of such baitfish, streamers are the obvious choice. Streamers are often preferred by many who pursue landlocks during their fall spawning runs, although nymphs and egg patterns also work very well at times.

Finally, with regard to their "troutiness"--the word "trout" is a quirky term, and it could be argued that landlocks have a better claim to it than any "trout" (rainbows, cutthroats, brookies, etc.) we pursue in the states except the brown.

Thanks, guys. I'm referring mainly to the atlantic version that live in the rivers and lakes in Northern Maine

Rainbow smelt are classic forage fish in many Maine lakes, and the streamer patterns that imitate them are legion. Many Maine lakes also have good Hex hatches. Resident stream fish should respond to imitations of seasonal hatches, as well as baitfish patterns. And, of course, there's always that classic New England standby--the Hornberg. :)
