Fish Atlas of the Northwest European seas reveals life and distribution of fish
September 15, 2015
The Fish Atlas is an in-depth reference work on marine fish. This is the first complete overview of all marine fish species found in the North Sea, Baltic Sea, and Celtic Sea. Whereas European research mainly focuses on species of commercial interest, this atlas documents current data of all Western European fish species caught in the period 1977 to 2013.
The Fish Atlas of the Celtic Sea, North Sea and Baltic Sea presents a unique set of abundance data to describe the spatial, depth, size, and temporal distribution of demersal and pelagic fish species over an extensive marine area, together with accounts of their biology. A large number of pictures, graphs and distribution maps illustrate the text. By largely avoiding – or at least explaining – scientific terms and providing extensive references, the book should be useful for both laymen and scientists.
The quantitative information on some 200 fish taxa is derived from 72,000 stations fished by research vessels during the period 1977-2013. The area covers the northwest European shelf from the west of Ireland to the central Baltic Sea and from Brittany to the Shetlands.
Although the surveys extend beyond the shelf edge, only taxa reported at least once in waters less than 200 m are included. Typical deep-water species and typical fresh-water species are excluded. We hope this publication will contribute to gaining a better understanding of the ocean ecosystems.
The Fish Atlas of the Celtic Sea, North Sea, and Baltic Sea contains:
- description of general goals of research-vessel surveys;
- brief account of the oceanographic features of the three ecoregions;
- overview of the surveys included in the analysis;
- details on the process and interpretation of the extensive data;
- variation of species composition by area and in time;
- information on 201 taxa, grouped in 78 families;
- contributions of 31 authors, affiliated with ICES surveys;
- full-colour pictures, clear distribution maps and graphs;
- 48 text boxes to describe additional details of general interest.
The majority of Bavaria’s watercourses are in poor ecological condition. A team has now conducted the first systematic analysis of long-term data on fish stocks in the Upper Danube, Elbe and Main rivers. The team concluded that native fish species are on the verge of extinction, while the populations of some invasive species are increasing: here.
