As an island nation we don't really eat a lot of fish or seafood. Sure your nan might have a bit of plaice and we've all dabbled with some prawns now and then but compared to some other European countries eg Spain, Italy, Greece etc we are well behind. Perhaps it's the climate and culture.
How often do you eat fish and seafood and how often when going out for a meal do you choose either fish or seafood? Have a think and let me know.
