Smoking Methods
There are two general methods of smoking fish: hot-smoking and cold-smoking.
Hot-smoking (also called barbecuing or kippering) requires a short brining time and smoking temperatures of 90°F for the first 2 hours and 150°F for an additional 4-8 hours. Hot-smoked fish are moist, lightly salted, and fully cooked, but they will keep in the refrigerator for only a few days.
Cold-smoking requires a longer brining time, lower temperature (80-90°F) and extended smoking time (1-5 days or more of steady smoking). Cold-smoked fish contain more salt and less moisture than hot-smoked fish. If the fish has been sufficiently cured, it will keep in the refrigerator for several months.
