Rehabilitation effort for anadromous salmonids in the river Meuse basin. Achievements and new challenges
Until the end of the 19th century, the Atlantic salmon (Salmo salar) was widespread in the river Meuse basin and salmon fisheries were prosperous in France, Belgium and The Netherlands. The number of salmon and sea trout captures reaches 57000 ind/year in the Dutch Rhine-Meuse delta. Between 1840 an...
