Benefits of globalised fish farming tempered by hidden costs

THAT smoked salmon you bought for the New Year's festivities has a story to tell.

The salmon may have been raised in Scotland - but it probably began life as roe in Norway. Harvested at a coastal farm, the fish may have been sent to Poland to be smoked. It may even have travelled halfway around the world to China to be sliced. It eventually arrived, wrapped in that tempting package, in your supermarket.
