Price Up: Wild-Caught Fish
Wild-caught fish could be on its way to becoming a special treat: The global fish-price index of the UN's Food and Agricultural Organization (FAO) hit a record high earlier this year, a result of increased demand and a surge in oil prices (which has a big impact on the cost of operating fishing boats and transporting the catch). Fish that is wild (not farmed) has seen the sharpest price hike, nearly doubling between 1990 and 2012, whereas the index for farmed fish rose by only a fifth (here's why). Some of the best eco- (and wallet-) friendly options are farm-raised striped bass or farm-raised rainbow trout, which sell for about $8 a pound and have relatively light impact on the environment. That's significantly lower than wild-caught fish that offer a similar taste and texture, such as cod (which ranges from $14 to $25 a pound) or halibut ($24 a pound).
