Ziel der Reise / Objectives of Cruise:
The main objective of the survey was to assess the pelagic fish stocks in the south-western part of the central Baltic Sea.Related to the project "Trophic interactions between zooplankton and fish under the influence of physical processes" (GLOBEC Germany), the following further objectives have been covered during the cruise. - Investigation of the horizontal distribution and abundance of sprat and herring - Investigation of vertical distribution patterns of sprat related to the distribution of oceanographic paramenters- Sampling of sprat, herring and cod for biological investigations (diet, maturity, fecundity, age) - Investigation of the actual hydrographic situation in the area of investigation
