| Objectives | Integrated Monitoring of Contaminants and their Biological Effects (INMON)
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 five Baltic Sea and seven North Sea areas. In addition to the onboard examination of dab (Limanda limanda), flounder (Platichtys flesus) and cod (Gadus morhua) for macroscopic externally and internally visible diseases and parasites, a large range of fish samples were taken for a subsequent analysis of contaminants (organic, inorganic and radioactive substances) and their biological effects. As part of the DAIMON2 project, extensive studies were carried out on the health status of cod in a dumping area for chemical munitions in Bornholm Basin and in Baltic Sea reference areas. Furthermore, hydrographical measurements were carried out (water temperature, salinity, oxygen content) and water samples were taken for measurement of radioactive substances. |
