Ziel der Reise / Objectives of Cruise:

The cruise was conducted as a training course for advanced students at the IHF in the context of the master course of Marine Ecosystem and Fisheries Science at Hamburg University. On the cruise 7 students were trained on frequently used fisheries science and biological oceanography methods. The cruise was designed according to the standards of scientific cruises and coupled to ongoing research activities of the institute. The more advanced students can undertake sampling for their own master or PhD thesis. The cruise was designed to get informations about the plankton and fish distribution, especially sprat between the Kiel Bight and the Gotland Basin in the Baltic Sea. One important aspect was the recording of the planktonic prey of larval and adult life stages of sprat and cod in different basins of the Baltic Sea with a VideoPlanktonRecorder (VPR) to get informations about small scale patchiness in zoopankton distribution and for the parameterisation of prey fields as input for consumption models. At the same time CTD, Multi net and Bongo net sampling was performed to investigate the spatial distribution and development of zoo- and ichthyoplankton and its hydrographic environment. Another aspect of the cruise was essentially dedicated to a first study on the distribution of the invasive round goby along the coast on the southern Baltic Sea (Gdansk Bay to Arkona Sea). For this purpose, a 3m beam trawl was used.
