Ziel der Reise / Objectives of Cruise:

The cruise was performed to investigate if fish in the North Sea in the area west of the island Sylt (Sylt Hornum) (trawl line 83 of DYFS) are affected by munition compounds (MC) leaking from marine dumped munitions. The cruise used 3m beam trawls in close proximity to munition dumping sites. Main target species was the bottom dwelling flat fish, common dab (Limanda limanda), since they live relatively stationary. As a control site an area North East of Helgoland (trawl line 107 of DYFS) was used. Overall numbers of collected dab and other flatfish was low (Hornum 6 dab, 2 flounder, 1 plaice, Helgoland NNO 4 dab, 4 plaice). However, fish were inspected for externally visible diseases and body fluid and tissue samples were collected and stored for later analysis in the laboratory.
