I live in Southern Cali and around here you have the typical large chain super markets like the usual ... Ralph, Albertsons, Stater Brothers ... and the likes. For whatever reasons, their seafood selections are for lack of a better works, are very and I mean very limited. They have the usual stuffs like Salmons, frozen cat fish, tilapia, and maybe some type of shell fish if you're lucky but beyond the very basic stuffs, they don't really any good stuffs. For example, if I need to buy fresh clams I am not sure any of the local supermarkets have them. But luckily we have a lot of asian markets around here which have all sorts of whatever fish you want ... fresh, pre-cut, live crabs (try to find it in any large chain markets), fresh clams. One thing I find puzzling is in asian market, they have a good selection of New England frozen mussels. Now these are domestic products and not something from the other side of the ocean so why on earth no typical supermarkets around here carry them. So let's say if there weren't any asian markets, where would one go buy fish?
