Harbour porpoises eat approximately ten percent of their body weight in fish per day. Their diet mainly comprises gobies, whiting, sand lances, herring and sprats. These mammals are in constant danger of starvation. Other major causes of death include drowning after becoming entangled in fishing nets on the seabed, and being hunted and eaten by grey seals. These findings are from research carried out by Mardik Leopold from IMARES Wageningen UR. He will be awarded a PhD by Wageningen University on 20 November.
