But then there's also this concern about sustainability—and choosing seafood that's sustainable.

So, if you're like me, you often stand at the fish counter a little perplexed: what's good for me and the planet?

To make the list, last updated in January 2010, fish must: a) have low levels of contaminants—below 216 parts per billion [ppb] mercury and 11 ppb PCBs; b) be high in health-promoting omega-3 fats; and c) come from a sustainable fishery.

Check out the slideshow above for 6 fish you should eat and 6 you should avoid.
