The fish you buy may not be what they say it is

Tree Hugger - Oceana is a great NGO focusing on ocean conservation. Over the past few years, they've done detective work using DNA testing to figure out if fish sold in grocery stores, restaurants, and sushi venues was properly labeled or if certain species were being passed off as other, more commercially desirable ones.

It turns out that out of the 1200 seafood samples Oceana collected from 674 retail outlets in 21 states, 33% were mislabeled. The graph below shows that sushi places are the worst offender, with 3/4 of samples tested not what they claimed to be!

59% of the fish labeled 'tuna' sold at restaurants and grocery stores in the U.S. is not actually tuna, and 87% of 'snapper' tested is not actually snapper ("In fact, only seven of the 120 samples of red snapper purchased nationwide were actually red snapper. The other 113 samples were another fish.").
