This annual report presents the results of post-mortem examinations of porpoises stranded on the Dutchcoast. One of the main objectives of the research is to quantify human-induced causes of death. In 2016, 55dead harbour porpoises were examined: 31 males and 24 females, including 14 adults, 33 juveniles and 8neonates. Most of the harbour porpoises examined died as a result of grey seal attacks (31%), infectiousdiseases (29%) or food shortage (18%). Bycatch was the cause of death in 11% of the harbour porpoisesexamined In dit jaarrapport worden de resultaten gepresenteerd van pathologisch onderzoek aan bruinvissen diegestrand zijn op de Nederlandse kust. Eén van de hoofddoelen van het onderzoek is het kwantificeren vansterfte van bruinvissen door menselijk toedoen. In 2016 zijn 55 dode bruinvissen onderzocht; 31 mannetjesen 24 vrouwtjes, waaronder 14 volwassen, 33 juveniel en 8 neonaat.
