Marine Mammal Sci (2004)
(...) In this study we used data collected from commercial dolphin-watching trips to determine whether there was any relationship between the probabilities of sighting bottlenose dolphins and harbor porpoises. Surveys…

Observations of altered behavior of marine mammals in the area of mid-range sonar use by the naval vessel USS SHOUP in the eastern Strait of Juan de Fuca and Haro…
Seasonal abundance, distribution, and prey species of harbour porpoise (Phocoena phocoena) in southern Vancouver island waters
Hall, A.
Master's Thesis - University of British Columbia (2004)
Harbour porpoise (Phocoena phocoena) occur year round in the waters of southern British Columbia, but little is known about their seasonal abundance, habitat use and food habits. A systematic vessel-based…

Borrell, Asunción; Aguilar, Alex; Cantos, Gemma; Lockyer, Christina; Heide-Jørgensen, Mads Peter; Jensen, Jette
Environmental Pollution (2004)
During the 1995 hunting season, 75 harbour porpoises (Phocoena phocoena) were sampled in three locations in West Greenland: Maniitsoq, Nuuk, and Paamiut. Sex, age, morphometrics, reproductive condition, and organochlorine compound…
Echolocation behavior of harbor porpoises Phocoena phocoena around chemically enhanced gill nets
Cox, T. M.; Read, A. J.
Marine Ecology Progress Series (2004)
The echolocation behavior of harbor porpoises Phocoena phocoena around gillnets was monitored to test their response to chemically (BaSO4) enhanced gill nets, designed to be more acoustically reflective than commercial…
Entrapment of harbour porpoises (Phocoena phocoena) in herring weirs in the Bay of Fundy, Canada
Neimanis, A. S.; Koopman, H. N.; Westgate, A. J.; Murison, L. D.; Read, A. J.
Journal of Cetacean Research and Management (2004)
Harbour porpoises (Phocoena phocoena) are small coastal cetaceans vulnerable to mortality in fishing operations. Not all interactions are fatal, however, and each year many porpoises swim into and are subsequently…
Natural hybridization between Dall’s porpoises (Phocoenoides dalli) and harbour porpoises (Phocoena phocoena)
Willis, Pamela M; Crespi, Bernard J; Dill, Lawrence M; Baird, Robin W; Hanson, M Bradley
Can. J. Zool. (2004)
Natural hybridization occurs rarely in mammals compared with other taxonomic groups of animals. Cetaceans appear unique among mammals in exhibiting striking karyological uniformity, which suggests that they have the potential…
Bycatch as a potential threat to harbour porpoises (Phocoena phocoena) in Polish Baltic waters
Skóra, Krzysztof E; Kuklik, Iwona
NAMMCOSP (2003)
Sixty-two verified reports obtained in the years 1990-1999 on the bycatch, strandings and sightings of harbour porpoises in the Polish Baltic were analysed in this study. In relative terms the…
The diet of harbour porpoise (Phocoena phocoena) in the northeast Atlantic
Santos, M.B.; Pierce, G.J.
Oceanography and Marine Biology: an Annual Review (2003)
The harbour porpoise (Phocoena phocoena) is probably the most abundant small cetacean in the northeast Atlantic and as such is an important top predator. It is also one of the…
Harbour porpoises (Phocoena phocoena) in the North Atlantic: Distribution and genetic population structure
Andersen, Liselotte Wesley
NAMMCOSP (2003)
The known geographical distribution (based on ship surveys, aerial surveys, incidental sightings, stranding and bycatch data) and the population genetic structure obtained from mitochondria DNA and nuclear DNA (isozymes and…
