Fish farming comes into its own

With the world's supply of wild fish fast depleting, diners turn to farmed fish in unprecedented numbers

Eighty per cent of the world’s wild fisheries are at or beyond their maximum yields and with over-fishing continuing to grow, they risk collapsing like the Grand Banks cod fisheries in the 1990s. But all is not lost: the world’s population of fish is growing at a faster rate than the human population, thanks to fish farming. Thanks to this growing supply the UN’s Food and Agriculture Organization calculates that half the world’s food fish are now farmed, up from a third just seven years ago.
