Yep, the fish I smoke are all caught by me or friends that came on the trip. While not really difficult (I mean all smoked fish is pretty tasty), it takes some time to get it just right. Oh and, you can smoke any fish, you don't need to go out and catch them, you can buy them from the fish market too.
Sweet, I'll try it with some store-bought fish since I can't catch any. Must be really satisfying to eat what you've caught and smoked yourself, though.
