#1: Canned solid white albacore has significantly higher levels of mercury than the chunk light tuna cans- because it's harvested from adult fish, not young fish.
Mercury in tuna: Consumer Reports
(Not a scientific article, but I don't feel up to a journal search

)
#2: I can't argue with this one. I don't think wild Atlantic salmon is sold anywhere, and I would recommend against the farmed just because I think it tastes like garbage!
#3: Currently the only Atlantic flatfish in the northeast that's overfished is the Atlantic halibut. All other stocks have no overfishing occuring. This segment is pure misinformation, and it's a travesty to recommend people eat tilapia, which eat poop. You are what you eat!
#4: Yeah, gotta say I agree with this one too, buy domestic.
#5: Tough call. Pieces of insects? Rinse your shrimp before you cook them, like most people. And it's often quite difficult (and expensive) to get wild domestic shrimp (excluding pandalus). Personally I only eat the domestic Gulf of Mexico shrimp... But I had never seen them for sale before I moved to Gloucester, so I'm not sure what the average consumer is to do.
If you look at the full list, they recommend squid as an alternative for those who like to eat eel. Go figure. They speak out against Atlantic cod, which is rebuilt in the GoM (not so on Georges, but different stocks). Also, the shortened list in that article neglects to mention shark, Patagonian toothfish, and orange roughy, species that are actually in bad shape.
I'd say the misinformation in that article far outweighs the benefits- Hence my reaction!
