| Abstract |
The Atlantic salmon, Salmo salar, was once a major fishing industry along the River Rhine. This paper discusses the Dutch and German salmon catches over the years 1863-1950. Factors such as the increased use of locks and weirs along the Rhine, coupled with growth in pollution, led to a rapid decline in numbers. By 1933, the salmon fishing industry in the Netherlands had virtually ceased to exist. Of particular importance in the context of the Rhine are: the closure of two of the major migration routes to the sea (Haringvliet and Zuiderzee); morphological changes in the river; chemical and thermal pollution; the loss of accessible spawning and nursery areas of the required quality; the disappearance of salmon from other rivers that flow into the North Sea such as the Rivers Elbe, Weser and Ems. If salmon were only reintroduced into the Rhine, a certain proportion would probably stray and infiltrate these other rivers. |
