| Purpose | Research |
| Objectives | As part of the integrated monitoring programme of the Thünen 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 six Baltic Sea and six North Sea areas. In addition to the onboard examination of dab (Limanda limanda), flounder (Platichthys flesus) and cod (Gadus morhua) for macroscopically externally and internally visible diseases and parasites, a large range of fish samples were taken for a subsequent analysis of contaminants (incl. radioactive substances), their biological effects and the presence of plastic particles in the stomach and intestine of fish (PlasM project). As part of the DAIMON project, studies were carried out on the health status of fish in dumping areas for chemical munitions and in reference areas. Furthermore, sediment samples were taken and hydrographical measurements were carried out (water temperature, salinity, oxygen content, turbidity). A neuston net was operated to sample litter particles at the water surface, and macro litter particles in the bottom trawl were classified and quantified for each fishery haul. |
