J-Fish

After a successful day on the Charlotte I confirmed the browns are living off crayfish. These free stone streams around here are full of them. Using what I had in my desk I took a stab at a crayfish pattern. I think the action of the marabou should imitate the tail flick and the way the claws just trail loosely as they flit along the bottom. 

Hook: #6 streamer, weighted w/ lead-free wire. 

Thread: olive 6/0

Claws (tail): 2 tufts of olive marabou, divided and posted to the sides
