A captive harbour porpoise (Phocoena phocoena) was monitored for 80 consecutive days, 10 days before attachment of a satellite dive recorder and a VHF-radio tag, 30 days during attachment and…
Throughout its range, the distribution of the harbour porpoise (Phocoena phocoena L.) has contracted significantly in the last century, particularly in the North Sea. Reasons for this decline have been…

The harbour porpoises kept at the Fjord & Bælt since April 1997 offer a unique opportunity to gain a better understanding of the reproductive function in harbour porpoises, especially in…
Two harbour porpoises of an estimated age of 1-2 years were held in captivity from April 1997 and were still alive in April 2002, after rescue from pound nets set…
The authors made 39 surveys (a total of 161 days) in the Tian-e-Zhou Oxbow of the Yangtze River, China, for observing 13 Yangtze finless porpoises (Neophocaena phocaenoides asiaeorientalis) captured from…
