I just ran across this photo of fish on offer at a restaurant in Taiwan. I ate here a couple of years ago. There must have been 50 types of fresh fish to choose form. There was also a wall of live fish and crabs in aquariums. Fortunately my Taiwanese companions ordered for us. They just wandered among the buckets and coolers pointing to the fish they wanted and telling the server how they'd like them cooked, or not.
I hope the fisheries are somewhat sustainable? We have pretty good seafood market in Annapolis, but nowhere near this selection.
