Ancient people’s fishing practices could keep one coveted seafood on the menu

I have a confession: I’m a little bit of an oyster snob. I’m Scottish, so my oysters are typically the variety that is plucked out of the sea that day and served immediately, pier and beach optional. Fresh and unadulterated save for a squeeze of lemon, an oyster is a true food joy that makes it very easy to forget the fact that they are essentially the ocean’s own sanitation plant.
