Ah, the cultural differences! In my nearest village (population around 2500) we have two supermarkets, both selling fish in various forms; fish from Finnish lakes and Baltic Sea, fresh, smoked, frozen, canned, etc. Farmed Norwegian salmon and bulk-imported canned tuna. Many of these are cheaper than most of meat. So I just stupidly assumed that eating fish is a mere question of what one chooses in the supermarket - simply because that's how it is in Finland, where we have thousand lakes and fish is a traditional part of typical diet.
