(Beijing) -- There's a gulf between the fish catches of thirty years ago and today around the world. But in places like the Bohai Sea, the Zhoushan Islands and the Beibu Gulf, a fishing industry reeling in lighter and lighter nets has yet to reach for sustainable production labeling.

It isn't just the dearth of wild caught fish that has lead to environmental issues, but a massive boom in farmed fish. As the world's largest fish consumer and producer, the country accounts for roughly 60 percent of the world's total fish production.
