Ziel der Reise / Objectives of Cruise:

Within the two projects - CODYSSEY "Cod spatial dynamics and vertical movements in European waters and implications for fishery management", and - GLOBEC Germany "Trophic interaction between zooplankton and fish under the influence of physical processes" a hydrographic survey was run in the Arkona Basin, the Bornholm Basin, the Stolpe Trench, the Gdansk Basin, and in the Gotland Basin, including investigations on phyto-, zoo- and ichthyplankton distributions as well as on pelagic clupeid and gadoid fish. Other major goals were the description of abundance, biomass, production and nutritional condition of phyto-, zoo- and ichthyoplankton. Further emphasis was given on the meso- to small-scale horizontal distribution of their main predator fish species herring and sprat. Additionally, stock structure, gonadal maturation, egg production and survival of sprat and cod was investigated.
