Long-term (1981-1985) results of recording several diseases of dab, plaice and cod are presented for the south-east area of the North Sea. The occurrence of each disease is geographically plotted, and observed average and maximum prevalence levels are given and d~scussed. Results underline that diseases in marine wild fish stocks can differ strongly per fish species, area and season. Fish disease recording in standard stockassessment surveys can be considered potentially useful and largely agrees with prevalence levels observed during special fish disease surveys in the same area.
