Fish farming has not been a work of pristine success. But we're learning. And we really need to keep learning.
Levels of wild-fish catches have been stable since the mid-1980s, and the vast majority of the world’s capture-fisheries are fully exploited—or indeed over-exploited: we cannot, therefore, catch more wild fish than we do today. But the demand for fish is booming, thanks to growing numbers of people, and their increasing affluence.

The key is to define what winning is and make sure the market rewards the winners.
