Guide to fish

For the people who care about sustainable fisheries etc (sometimes I do, sometimes I don't): Saw this at http://bitten.blogs.nytimes.com/2008/02/12/shopping-for-fish/: if you're in the grocery store thinking of buying a fish, and have a cell phone (here in Zurich we got one, and it is convenient), text FISH and the name of the fish to 30644 in order to get info on whether that fish is from a sustainable fishery or not. The article also links to a wallet-sized PDF guide to stick into your wallet, here.
