| Purpose | Research |
| Objectives | As part of the long-term monitoring programme of the Thünen Institute of Fisheries Ecology on diseases and parasites of marine fish species and in the framework of the EU-funded CHEMSEA project (Chemical Munitions - Search and Assessment), studies were conducted in 6 Baltic Sea areas. Due to technical problems, the start of the cruise had to be postponed from 01/12 to 10/12, and therefore not all sampling sites in the Baltic Sea could be visited and the North Sea sampling was completely cancelled. In addition to the examination of dab (Limanda limanda), Baltic cod (Gadus morhua) and Baltic flounder (Platichthys flesus) for macroscopically visible external and internal diseases and parasites, extensive samples for the CHEMSEA project were taken for measurements on dumped chemical weapons and their biological effects. In particular, cod samples were taken for the CHEMSEA project in area B14 (Gotland Basin). In addition, fish samples were frozen for the detection of contaminants (incl. radioactive substances) in the framework of national legislation (BLMP) and international monitoring programmes (HELCOM). Hydrographical measurements were carried out (water temperature, salinity, oxygen content, turbidity). |
