Not a smolt pattern but an alvin/fry pattern. I imagine it should work for most pan fish and bass when the fry are hatching. Might work in rivers for trout and steelhead.
Rude and crude pattern that I haven't messed with much since first tying but has a lot of potential if I ever sat down and tried to make it look more fishy.
My favorite minnow pattern would have to be Crappie Candy followed by the Clouser minnow. That is until I decide to set down and perfect that alvin pattern.
