ABSTRACT

The migratory behavior of the anadromous Atlantic salmon (Salmo salar L.) has intrigued anglers, scientists and fi shery managers for centuries. In his treatise on angling, The Compleat Angler published in 1653, Izaak Walton, reports: “Sir Francis Bacon observed, the age of a salmon exceeds not ten years…much of this has been observed by tying a ribbon or some known tape or thread, in the tail of some young salmons, which have been taken in weirs as they have swimmed toward the salt water, and then by taking a part of them again with the known mark at the same place at their return from the sea, which is usually about six months after....which has inclined many to think, that every salmon usually returns to the same river to which it was bred.”
