4.2 Sampling of biota 
Fish from the North Sea and the Baltic Sea was sampled by the Institute of Fishery 
Ecology of the Federal Research Centre for Fisheries (BFA-Fi, Hamburg). Sampling 
was performed within the framework of the regular annual research cruises for 
monitoring hazardous substances and bio-effects during late August/September in 2002, 
2003, and 2004. The grid of stations covered North Sea areas from the German Bight to 
the northern Scottish waters as well as the Baltic Sea from the Kiel Bight to the Baltic 
Proper.
