Fish stocks online

Development and maintenance of an internet presence with the current description of the state of fish stocks (Fischbestände Online, engl.: fish stocks online)

Media and sourcing guides provide contradicting information on the condition of fish stocks. Can a fish dealer still offer North Sea cod without bad conscience? What about the state of herring in the Baltic Sea? Is there any sustainably harvested hake stock available?

Background and Objective

The initiative for the internet database "Fischbestände Online" (engl. fish stocks online) goes back to the "Roundtable Sustainable Fishing" of the Federal Ministry of Food and Agriculture (BMEL). After the more precise definition of fishing areas in late 2008, its members developed the idea of setting up an internet database to represent the stock situation of commercially exploited marine fish stocks. In October 2009 the prototype of "Fischbestände Online" was presented at the food and beverage fair ANUGA in Cologne and in January 2010 the Thünen Institute of Baltic Sea Fisheries was commissioned to build up this database.

On the website "Fischbestände Online" we give up-to-date information on the state of wild marine fish stocks, which are relevant for the German retail market and on all issues which are relevant for their sustainable use. We provide  scientifically correct information, brief, understandable and up-to date.

Target Group

The information we provide on "Fischbestände online" is aimed at the general public, but especially at companies in the trade and processing industry. With scientifically correct information, we want to help them to develop their sustainable sourcing policies. Of course, environmental groups, pupils, students and representatives of the press are invited to use the site as a source of information.


To fill the internet database "Fischbestände Online", we collect information from different scientific data sources around the world. For the state of the fish stocks there is only one source, the so-called stock assessments. These are repeated, depending on the stock, at regular or irregular intervals. In the same cycle we update "Fischbestände Online". In addition to the data on the stock status, we research more information on various aspects of sustainability, such as fisheries management and the environmental impact of fishing. An important source for the fish stocks in the Northeast Atlantic are the stock assessments of the International Council for the Exploration of the Sea (ICES).

Preliminary Results

At the end of the first project phase in January 2013, we provided on „Fischbestände Online“ information on 155 stocks of 31 fish and shellfish species. Apart from the regular updating of the existing resources, in the second project phase (until January 2016), our focus will be on the compilation of information on tuna and wild salmon stocks. In addition, we complete the database with information on different fishing gear and provide a standardized fishing gear nomenclature.
