Here's an interesting new resource for those who are concerned about the proliferation of fish that is less than fresh, and the introduction of Asian carp and other junk fish to restaurants and local markets (for example, "basa" a white fish which looks like haddock or cod in the showcase, comes from the Mekong Delta in Vietnam, one of the most polluted waterways in the world....but it's CHEAP, so they buy and sell it to unsuspecting customers, even when fresh, healthy, local fish may be available nearby.)
 
We live in Florida, not far from the docks where local fleets bring in many varieties of fresh, delicious fish, yet we found inferior basa, all the way from Vietnam, on the menu at the Big Game Restaurant in Fort Myers Beach and on display at Publix!
 
Read the signs and menus and ask tough questions. You may be surprised and angry at what you discover.  I was.
