| Summary: | In the Belgian River Meuse basin, most of the anadromous migrating fish were disappeared at the beginning of the last century. The most fabulous salmonid fish, the Atlantic salmon (Salmo salar) was completely disappeared around 1935. In 1983, sea trouts were discovered in the Belgian Meuse basin, allowing to consider a salmon restoration possible. This was realized and in 2002 the first breeders were caught in a fish pass on the River Meuse at the Visé-Lixhe navigation dam. This film overviews the different steps of the restoration of the Salmon in the Belgian River Meuse basin. Fertlized eggs from Scotland were reared in an experimental fish farm for restocking purposes. Scientific studies were undertaken to assess the adaptation of stocked salmon parrs in the wild (habitat studies by means of electrofishing or diving, behaviour studies, capture, capture of migrating smolts, radio-tracking). Fishways were also studied and improved in order to allow upstream migration movements. The case study of other migrating fish such as eels was also discussed. |
