A voracious predator which lives mostly in the more frigid waters of the world, salmon was considered a delicacy by the Celts of Gaul and Britain, with salmon populations in Scotland and Norway being the most notable. The Irish tale of the Salmon of Wisdom, a fish which upon being eaten could confer all knowledge in the world on whoever consumed it, attests to its importance well into our own times. Not everyone likes salmon though as the fatty taste can put many off. Contrary to belief salmon was not popular in mediaeval Japan because it harboured parasites, although the Ainu tribes managed to avoid this issue by freezing the fish with snow before eating it raw.
