Postmortaal onderzoek van bruinvissen (Phocoena phocoena) uit Nederlandse wateren, 2019 : Biologische gegevens, gezondheidsstatus en doodsoorzaken
This annual report presents the results of post-mortem examinations of porpoises in 2019. One of the main objectives of the research is to quantify human-induced causes of death. In 2019, 57 dead harbour porpoises were examined: 31 males and 26 females, 22 adults, 24 juveniles and 11 neonates. There were an additional six foetuses found. Most of the examined harbour porpoises died as a result of infectious diseases (30%) and grey seal attacks (21%), followed by bycatch (11%).
