Living on Earth
The World
CURWOOD: When you're in a restaurant or a grocery store, thinking about fish for supper, you might also want to think about what could be in the fish?maybe mercury, perhaps PCBs? Or maybe the fishery is floundering. Some fish are good?some not?but can you remember which fish is which? Now you don't have to?you can let your fingers do the fishing, as Living on Earth's Ashley Ahearn learned when she dialed-a-fish at her local supermarket. [SOUNDS OF GROCERY STORE, BEEPING, PEOPLE WALKING] AHEARN: So I'm going to type in 'swordfish' and see what comes up. [CELL PHONE TEXT MESSAGE SOUND] AHEARN: It says; Atlantic and Mediterranean caught, few environmental concerns. It got a green rating. And they're high mercury, though. Okay, so maybe I won't do swordfish. I'm trying salmon now. [CELL PHONE TEXT MESSAGE SOUND] AHEARN: But for wild salmon it says it's fine. So I guess farmed salmon is off the menu for dinner, too. So yeah, that was me with my cell phone, talking to myself at the local market. As crazy as I might have looked, though, this service is really cool. It's called Fish Phone. The guy who dreamt it up is Carl Safina, head of the Blue Ocean Institute. I called him to find out how it works. SAFINA: You simply send a text message with the word 'fish' and the name of the fish that you are interested in and virtually instantly, you will get a beep on your phone and you will see whether you should tell the waiter that that's what you want to eat or you should tell the guy behind the counter or the woman behind the counter that that's what you want to buy. AHEARN: So it's kind of like cheating in a way. SAFINA: Uh, it's kind of like being a very informed consumer and feeling kind of smug about it. AHEARN: Carl Safina and his team have put together a database that rates each fish based on pollution exposure, fishing practices, population levels, even how long it takes that species to reproduce. SAFINA: And then we score all those things and then we relate the score to a color code and the code sort of ranges from green to light green to yellow to reddish yellow to red. AHEARN: I think Dr. Seuss wrote a poem about that. SAFINA: Yes, he did (laughs). Maybe subliminally that was our inspiration all along. AHEARN: But beyond the rating system, Carl has some basic rules of thumb for anyone buying fish, even if they don't have text messaging on their phone. SAFINA: Farmed shellfish is generally very good and then the smaller the fish is, the better it's likely to be. The bigger the fish, the more fished out it probably is and the more you might have a concern about mercury or other pollutants. But there are some surprises. For instance, the swordfish have come back up and they're doing much better than they were a decade ago. [SOUND OF GROCERY STORE, BEEPING AND PEOPLE TALKING] AHEARN: That doesn't really help me for dinner, though. Swordfish is a little bit out of my price range. But Safina says farmed shellfish is good. So, I'll text the number 30644, the word 'shrimp,' and let's see what my phone spits out now. [CELL PHONE TEXT MESSAGE SOUND] AHEARN: Oh, okay, so if I get farmed shrimp, I'm okay, it looks like, from here. So shrimp it is for dinner. Thank you Carl Safina. Thank you Fish Phone. Alright, great. Can I get a half a pound of the farm-raised? For Living on Earth, I'm Ashley Ahearn. [MUSIC: Taj Mahal "I'm A Goin Fishin" from The Real Thing (Sony Music 1971)]
