I've been using a similar brine for a few years for trout and salmon and I agree, the trout is crazy good. I have a charcoal and an electric smoker and I like using the electric smoker for fish because you can smoke at a lower temp. I usually start around 220 for 30 minutes, then drop to 185 for another 60-90 minutes until it flakes easily. I usually buy trout filets - whole fish probably take a bit longer.
