Context of the study
The harbour porpoise is a vulnerable species in European waters. During the past decades the number of observations of this cetacean have decreased in the Baltic sea. Observations along the coast of the Netherlands have increased since 1990. This trend however is more likely to reflect a shift in distribution of harbour porpoises then an actual increase of the population. [1] One of the main threats to the harbour porpoise is accidental capture by fishing gear. High levels of contaminants, declining fish stocks and other anthropogenic stress factors (wind mills, sonar, shipping,... [2]) are also considered possible threats.
