: crab imitation

in the waters I fish for trout there´s a bunch of crabs that look like the one in the pictures. They let themselves drift in the water and can swim and hide underneath rocks.
In my local fly shop they have very good crab imitations but made out of something that looks like stuffed cloth, more or less like a teddy bear. Its kind of rigid and it cannot mimic a swimming motin.

The closes thing for imitating it a real crab is a olive woolly bugger. Its tail action more or less imitates the crabs swimming motion, but I was wondering if theres any closer pattern that looks more like a crab and can actually mimic a swimming motion. Thank you

You have freshwater crabs that trout eat there? Interesting!

in a river 30 minutes drive, that fresh water crab is the only thing the trout will eat. Mayflie and Caddis hatches are not big and frequent enough for them to be real food for the trout, so the trout rarely go surface feeding (but they will take nymphs of these insects and stone fly). Plus there is no good cover, no vegetation, except under the rocks in the bottom, right where the crabs live.

The fly that works OK is a weird hybrid: its a olive and orange woolly bugger with a wing case (!) and three long rubber legs crossing the body in right angles (resulting in 6 perpendicular legs). I tend to think its working more as an attractor fly rather the trout mistaken it for a crab...but I could be wrong.

People fish it casted upstream, mended upstream for depht, then dead drift with ocasional short and violent strips.

That's wild! Never heard of that before.

I hope to try it someday.

Is this the congrejos crab the McClane refers to that adds a bright orange flesh (and wonderful flavor) to the trout in your rivers where the crabs occur?
I don't really have any particular suggestions, but do a search on the site for crab patterns — there are a number of them. Following is the link to the mesh crab that I've found productive on bonefish.

I have´nt heard of Mclane, but yes, we call them "cangrejo" in argentina and its called "pancora" in chile. And yes, I´ve heard the same thing, that salmon eating lots of shrimp gives them that color, same with the crabs and trout.

Thanks for the patterns they look nice, that body material looks like it could emulate a spoon effect under water.

Juro check out the Tolten river in south chile, they have nice salmon runs or you can fish for "fario" browns with crab imitations. The river close to my home is a to say...humble river.
