The population development of larger fish-eating bird species is increasingly viewed with concern by the fisheries sector. This is especially true of the Great Cormorant, Grey Heron and Goosander. As bird species that feed exclusively or to a large extent on fish, they are seen as competitors or blamed for the decline in fish stocks.
The Swiss Ornithological Institute offers authorities, associations and private individuals its expertise on the subject of “piscivorous bird species and fisheries” and strives to engage in objective discussion.
