Also always remove the skin before smoking it. In the smoker, put the sawdust first, then some foil....grid .....fish with some Ina Paarman rosemary and olive seasoning. I also cut some sqares into the meat to improve smoke penetration...A +- 2.5 kg rocksalmon is just hardly ever released anymore
Oh, and I never remove the fins....nobody eats it anyway...it pulls out easily when fish is done
