I think you will find what you need in this section. Pork Belly has a good post regarding scallops and shrimp and I am sure that salmon is adequately covered. Mostly though, you will need to experiment because you cannot lay eyes on the food. Fair warning: You will experience a heat dump. And if still producing smoke, you can be engulfed in it. So go with what others have done regarding heat and time and adjust from there.
