Abstract taken from part of the introduction: Despite past controversy, it is now agreed that there is one species of trout native to north-western Europe - Salmo trutta. As the ice retreated at the end of the last ice age the rivers of northern Europe were colonised via the sea by two successive forms of trout. Both of these forms gave rise to brown trout which lived wholly in fresh water. Some of their modern descendants migrate to the sea but no consistent morphological criteria have been found to distinguish sea-run from non-migratory brown trout. It is still common for sea-run trout to be called Salmo trutta trutta and freshwater brown trout to be called Salmo trutta fario (MacCrimmon and Marshall, 1968; LeCren, 1984). For the purposes of this review, both forms will be considered, but only in the freshwater resident phase. The brown trout (Salmo trutta Linnaeus) is native to the European coast of the Atlantic Ocean and to the coast of the Mediterranean Sea. Its natural distribution includes Iceland, ...
