If you eat seafood, unless you catch it yourself or ask the right questions, the odds are pretty good it comes from a fish farm. The aquaculture industry is like a whale on steroids, growing faster than any other animal agriculture segment and now accounting for half the fish eaten in the U.S. As commercial fishing operations continue to strip the world’s oceans of life, with one-third of fishing stocks collapsed and the rest headed there by mid-century, fish farming is increasingly seen as a way to meet the world’s growing demand.
