Place 1 cup of the wood chips in water to soak for 30 minutes.
Remove fish from fridge. Place a piece of foil on top of the grill where there is no direct heat - over the drip pan. Again using a fork, poke holes in the foil for the smoke to permeate through. Carefully place the delicate marinated fish on the foil and close the lid. Reduce the heat to 220 F (110 C) under the wood chip package to medium and leave the fish to smoke for 1 1/2 hours.
