In focus: Atlantic salmon
The Atlantic salmon is an anadromous fish. They spend their first years in freshwater, and when they are big enough they undergo physiological and morphological changes, and migrate into seawter as a ’smolt’. The smolt migrates from the rivers, throughout the fjords
and into the open seas where they spend one to four years. In this period they grow fast, and when they are sexually mature, they migrate back to the river where they were born, to spawn.
