Stomach contents were analyzed from 85 Dall's porpoises, Phocoenoides dalli, taken in the southern Sea of Okhotsk during the summer of 1988. Thirteen species of fish and five species of…
Violent interactions between bottlenose dolphins and harbour porpoises
Ross, H. M.; Wilson, B.
Proceedings of the Royal Society B: Biological Sciences (1996)
The majority (63%) of harbour porpoises stranded around the Moray Firth, Scotland, died from trauma characterized by multiple skeletal fractures and damaged internal organs. Surface injuries consisted of skin cuts…
The phylogeographic pattern of mitochondrial DNA variation in the Dall’s porpoise Phocoenoides dalli
MCMILLAN, W. O.; BERMINGHAM, E.
Molecular Ecology (1996)
We used 11 restriction endonucleases to study mtDNA variation in 101 Dall's porpoises Phocoenoides dalli from the Bering Sea and western North Pacific. There was little phylogeographic patterning among the…

Deterring harbour porpoises (Phocoena phocoena) from gillnets: Observed reactions to passive reflectors and pingers
Koschinski, S.; Culik, B.
Report of the International Whaling Commission (1997)
Bycatch of harbour porpoises (Phocoena phocoena) occurs in most gillnet fisheries throughout the continental shelf area in the Northern Hemisphere. A few behavioural studies have attempted to ascertain the detection…
A note on the harbour porpoise (Phocoena phocoena) in the coastal waters of Spain
Lens, S.
Report of the International Whaling Commission (1997)
Information on the harbour porpoise in Spanish waters was collected and reviewed, giving an updated list of observations (strandings, incidental catches and sightings) for the period 1978-94 . The species…
Monitoring the movements of harbour porpoises (Phocoena phocoena) with satellite telemetry
Read, A. J.; Westgate, A. J.
Marine Biology (1997)
The movements of nine harbour porpoises, Phocoena phocoena (L.), in the Bay of Fundy and Gulf of Maine were tracked using satellite telemetry. Transmitters were attached to the porpoises in…
