Food & Water Watch just released its 2010 Smart Seafood Guide to the safety and sustainability of more than 100 kinds of fish and shellfish. Now I still love the Monterey Bay Aquarium’s pocket guides and searchable Seafood Watch site (the only place where you can geek out with a trawling fact card, as far as I know), but the Smart Seafood Guide has a few unique features worth pointing out.

For starters, while some guides only address human health issues (like mercury) and environmental problems (like overfishing), Food & Water Watch also considers seafood’s socioeconomic impact. “For example, lobster is a a key part of the economy up in Maine,” says Marianne Cufone, director of Food & Water Watch’s fish program. “Knowing that fact is really important to some consumers.”

Another handy thing: It’s organized by texture and taste, so you can figure out the safest and most sustainable options in categories such as “mild” and “steak-like.” This makes it easy to figure out substitutes for recipes. 

Here’s Food & Water Watch’s “dirty dozen” list of seafood that failed to meet at least two of the group’s criteria. For more details, plus a list of alternatives for each verboten species, check out the guide. In no particular order:

1. King crab: Even though crab is abundant in some parts of the US, imports from Russia—which aren’t well regulated—are much cheaper and more common.

2. Caviar, especially from beluga and other wild-caught sturgeon: Overfishing and poaching of this coveted species is very common.

3. Atlantic bluefin tuna: Extreme overfishing, plus concerns about mercury and PCB contamination.

4. Orange roughy: May contain mercury and “is particularly vulnerable to overfishing due to its long lifespan and slow maturation.”

5. Atlantic flatfish (e.g. flounder, sole and halibut): Seriously overfished.

6. American eel: Concerns about mercury and PCBs.

7. Atlantic Cod: Overfished, and also has major bycatch problems.

8. Imported catfish: Much of it comes from Southeast Asia, “where use of chemicals and antibiotics is barely regulated.”

9. Chilean seabass: Concerns about mercury, plus illegal fishing in Chile damages marine life and seabirds.

10. Shark: May contain mercury, also overfished.

11. Atlantic and farmed salmon: Concerns about contamination with PCB, pesticides, and antibiotics. Also, waste and germs from salmon farms often leaches out of the cages and can harm the surrounding marine life.

12. Imported shrimp: About 90 percent of it comes from countries where the seafood industry (waste control, chemical use, and labor) isn’t well regulated.

WE CAME UP SHORT.

We just wrapped up a shorter-than-normal, urgent-as-ever fundraising drive and we came up about $45,000 short of our $300,000 goal.

That means we're going to have upwards of $350,000, maybe more, to raise in online donations between now and June 30, when our fiscal year ends and we have to get to break-even. And even though there's zero cushion to miss the mark, we won't be all that in your face about our fundraising again until June.

So we urgently need this specific ask, what you're reading right now, to start bringing in more donations than it ever has. The reality, for these next few months and next few years, is that we have to start finding ways to grow our online supporter base in a big way—and we're optimistic we can keep making real headway by being real with you about this.

Because the bottom line: Corporations and powerful people with deep pockets will never sustain the type of journalism Mother Jones exists to do. The only investors who won’t let independent, investigative journalism down are the people who actually care about its future—you.

And we hope you might consider pitching in before moving on to whatever it is you're about to do next. We really need to see if we'll be able to raise more with this real estate on a daily basis than we have been, so we're hoping to see a promising start.
