Ziel der Reise / Objectives of Cruise:

The fishery research trip was carried out to examine flatfish, especially dabs (Limanda limanda), near ammunition dumping areas in German waters of the Baltic Sea for diseases and residues of munition compounds (MC). Dabs from the Kolberger Heide ammunition dumping area in the Bay of Kiel and in the Bay of Flensburg east of the coast of Falshoft were caught and examined using ground gillnets. While dabs from the Kolberger Heide have already been sampled in previous surveys, this research trip was the first time that dabs were caught and examined in the 'Falshoft' area (Schleimunde Nord and Schleimunde Nord Ost). The research trip was hampered by bad weather and technical problems on the ship and unfortunately it was not possible to catch and examine the planned number of 30 dabs per location. Nevertheless, both locations, including the control locations, were sampled. Water samples were taken and dabs were caught and examined for disease on board. Body fluids and tissue samples were taken from the dabs and frozen for later laboratory studies on STV. Later analysis of dab samples in the laboratory revealed the presence of MC in bile fluid of dab investigated at Kolberger Heide and Schleimunde NO.
