At research pens in Chile researchers develop strains of farmed Atlantic salmon with improved traits such as growth and health.
By Erik StokstadTwo years ago, off the coast of Norway, the blue-hulled Ro Fjell pulled alongside Ocean Farm 1, a steel-netted pen the size of a city block.
Attaching a heavy vacuum hose to the pen, the ship’s crew began to pump brawny adult salmon out of the water and into a tank below deck.
Later, they offloaded the fish at a shore-based processing facility owned by SalMar, a major salmon aquaculture company.The 2018 harvest marked the debut of the world’s largest offshore fish pen, 110 meters wide.
