ObjectivesThis cruise covered fisheries research representing the German contribution to the International Bottom Trawl Survey (IBTS) in quarter III, as well as one component of the two-ship operation in the German Small-scale Bottom Trawl Survey (GSBTS). Both surveys use the same principle fishing methods but at different spatial scales, applying a GOV bottom trawl, accompanied by hydrographic measurements, investigations of benthic epifauna and sediments.

A total of 121 stations were sampled in the wider German Bight, and in the central and northern North Sea, including 120 GOV fishing stations. Besides the regular survey tasks, sampling was performed for stomach analyses of demersal and pelagic fish species (collaboration with Hamburg University). Furthermore, expanding the collection started in 2010 specimens of numerous fish and invertebrate species were collected for a project on marine genetic diversity (bar-coding), led by Senckenberg Research Institute (WG Molecular Taxonomy of Marine Organisms). For the Max Rubner Institute, tissue samples were obtained for analyses of parasite infestation, and for genetic as well as chemical analyses.
