Ziel der Reise / Objectives of Cruise:

The purpose of this trip was again the qualitative and quantitative recording of the demersal fish fauna in the German Exclusive Economic Zone (EEZ) of the North Sea. In conjunction with the results of investigations of the benthic invertebrate fauna of other research institutes possible changes due to increasing industrialization (wind farms, sand and gravel extraction) are to be detected. The entire EEZ was divided into different ecological zones and covered with a fixed station network. Since the investigation began in 2004, an annual exchange between the beam trawl and bottom trawl maintained. This year the investigations were therefore carried out again with the beam trawl. A total of 38 fish species and 52 invertebrate species were detected in the 40 carried out hauls with the beam trawl. The fish were dominated by species dab, plaice, whiting, solenet and scaldfish. The catch of invertebrates consisted mainly of starfish, swimming crabs and hermit crabs.
