Samenvatting

This study aimed towards a better insight in the necropsy findings of harbour porpoises that stranded during periods of high stranding frequency. To achieve this aim, the study was divided into two areas of research. The first area of this study focussed on stranding data. Firstly, it was necessary to detect a general trend. Once the trend was known, periods of high stranding frequency were detected. The second area of this study examined the necropsy dataset. This part focussed on finding differences and/or relations in necropsy findings between periods of high stranding frequency and the general trend.
