Résumé : |
The decline in the inland fish catches has become a topical issue in many countries. In the U.K., the threat to inland migratory salmonid and eel stocks, as well as a significant change in species composition, is well documented. In Norway, fish suffer from severe malformations. Fewer fish are being found in Danish and French waters. In Switzerland, the reported trout catch in streams and rivers has plummeted by 60% since the early 1980s (Figure 1). This drop has been accompanied by regional declines in fish health in Switzerland. What are the causes of this pan-European decline in fish catches, and how can it be reversed ? Switzerland is fortunate to have >240,000 recreational anglers. Proceeds from their fishing licenses benefit the maintenance of rivers and streams.

In the U.K., the threat to inland migratory salmonid and eel stocks, as well as a significant change in species composition, is well documented. In Norway, fish suffer from severe malformations.

This drop has been accompanied by regional declines in fish health in Switzerland. What are the causes of this pan-European decline in fish catches, and how can it be reversed ? Switzerland is fortunate to have >240,000 recreational anglers. Proceeds from their fishing licenses benefit the maintenance of rivers and streams. But, just as importantly, these anglers keep personal catch statistics and report them to SAEFL. In this article, we will explain how those data helped Fischnetz, a nationwide study, isolate the causes of the decline. |
