I've tried (token attempt) while sampling them for work. I don't see why it couldn't be done where we were, the walleye, pike, and redhorse piked up the flies... the sturgeon only went for the baited lines. Next year I will make an effort to target them with flies, sinking lines, softbodied flies with good motion, etc.

The sturgeon we were catching with conventional tackle ranged from 25lbs to 50lbs.
