Summary Since 1987 a bottom fish survey was carried out to monitor changes in fish assemblages in 12 small defined areas of 100 nm2 (boxes) distributed over the whole North Sea. At the same time water temperature, salinity and additionally in only 6 boxes nutrients, sediment and benthic invertebrates were measured or sampled. This small scale and simultaneous sampling of different variables allows the determination of quantitative relationships between fish and benthos. These results are also important as basic input data for a model to manage fisheries by an integrated advice. Furthermore, these data can be used to determine changes in the North Sea fish fauna due to climate change, eutrophication or anthropogenic activities like fisheries, sand and gravel extraction and offshore windfarms. The commercially important bottom fish data can also be used in multispecies assessment models to calculate the total allowable catches within the frame of a sustainable use of the marine resources. Working groups: ICES ACOM Cruises: annually 2 cruises FRV "Walther Herwig III" (GSBTS) and 3 cruises FRV "Solea" (GSBTS and parts of BTS) Participating institutions: Carl von Ossietzky University of Oldenburg, Germany; Senckenberg by the Sea, Wilhelmshaven, Germany.
