| 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), studies were carried out in six reference areas in the North Sea and three reference areas in the Irish Sea. In addition to the onboard examination of dab (Limanda limanda) 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 radioactive contaminants and the presence of plastic particles in the stomach and intestine of fish (PlasM project). 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. |
