The few times I caught finger lakers I gave them to my grandmother and she made "tuna fish" with them with olive oil salt, pepper and a sprig of mint leaf. They were pretty damn good.
If your a fly fisherman you might have a full sinking fly line. Try tying in a spoon a couple feet above a steamer.(take the hook off of the spoon first). I bet you could get them that way. You can adjust depth by the amount of line you let out. Just like lead core.
