No abstracts are to be cited without prior reference to the author.The ICES biological effects monitoring in pelagic ecosystems (BECPELAG) workshop is a multi-national, multi-disciplinary workshop aimed at establishing suitable techniques for monitoring the effects of contaminants on pelagic ecosystems. Fish larvae, blue mussels (Mytilus edulis) and cod (Gadus morhua) were evaluated for the presence of histological changes indicative of contaminant exposure. Fixed and sectioned specimens were examined for the presence of infectious diseases and for parasites, in addition to any morphological and toxicopathic tissue changes. Caged cod specimens displayed a number of pathologies with putative toxicopathic aetiology. Most significantly, changes in the histological appearance of the gonads of both male and female fish indicated a potential effect of contaminants on the caged cod. In this case, use of the terminal deoxynucleotidyl transferase-mediated dUTP-biotin nick end labelling (TUNEL) assay allowed for the ...
