Ziel der Reise / Objectives of Cruise:

As part of the integrated monitoring programme of the Thunen Institute of Fisheries Ecology (FI) on contaminants and biological effects (incl. fish diseases) in fish from the North Sea and Baltic Sea, studies were carried out in five Baltic Sea and five North Sea areas. In addition to the onboard examination of dab (Limanda limanda), flounder (Platichthys flesus) and cod (Gadus morhua) for macroscopical externally and internally visible diseases and parasites, a large range of fish samples were taken for a subsequent analysis of contaminants (incl. radioactive substances) and their biological effects. As part of the DAIMON project, extensive studies were carried out on the health status of cod in a dumping area for chemical munitions in Bornholm Basin and in a reference area outside the Gulf of Gdansk. In a dumpsite of conventional munitions located in Kiel Bight (Kolberger Heide, Baltic Sea), cages with dab deployed in early August during cruise 314 RC Clupea were retrieved by research divers. Furthermore, sediment samples were taken and hydrographical measurements were carried out (water temperature, salinity, oxygen content, turbidity).
