Description

Abstract:

Between 2000 and 2013, 250 hectares of habitats were made accessible to the dynamics of the Rhine. All in all more than 1,000 hectares of spawning and juvenile habitats are supposed to be opened in the Rhine catchment. The ecological network and the recovery of habitats benefit to migratory fish, but also to local fish species and invertebrates. Millions of young Salmons (and other species) have been stocked. All over the Rhine system the benefits of these actions are to be seen, by growing numbers of fish that had not been seen since long. There are even places where salmon stocking can step by step be reduced because of natural reproduction (in parts of the River Sieg system in the lower reaches of the Rhine) even though such stocking measures on the long run remain absolutely essential in the upper reaches of the Rhine, in order to increase the number of returnees and to enhance the carefully starting natural reproduction.
