I would season with a generous amount of lemon pepper and nothing else. I would build a very small fire, perhaps 5 or 6 briquettes of charcoal and put the fish on a piece of aluminum foil close to, but not over the fire. I would use any kind of fruit wood for the smoke-apple, cherry, peach work well.
The temperature at the grill level on mine usually reads around 140 degrees. It takes about 4 hours. The whole time it looks like nothing is happening, but when you press with your finger at the end of 4 hours you can tell it is done. It will still be pink and moist. I serve it on crackers with chopped onions, black pepper and lemon juice. You can also put a little cream cheese on the cracker first if you wish.
I have created a lot of followers with this receipe. :lol:
