Oil smokes to the surface/skin and drips/bastes.
I used to live in Bayfield Wisconsin and ate a whole lot of smoked Whitefish, smoked chub and smoked trout.
I would say smoked chub and smoked mullet are very similar... but chub are much smaller. I smoke mullet in the 1-2 lb range.
Applewood is a little mild in my opinion. I may try Hickory or Mesquite next.
