NAMMCOSP (2003)
Biological parameters for harbour porpoises are reviewed throughout their range in the North Atlantic. Most information is based on studies of a combination of directed catches, bycatches and strandings. All…
Monitoring growth and energy utilisation of the harbour porpoise (Phocoena phocoena) in human care
Lockyer, Christina; Desportes, Geneviève; Hansen, Kirstin; Labberté, Sabrina; Siebert, Ursula
NAMMCOSP (2003)
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…
Analysis of seasonal changes in reproductive organs from Icelandic harbour porpoises (Phocoena phocoena)
Halldórsson, Sverrir Daníel; Víkingsson, Gísli Arnór
NAMMCOSP (2003)
In this study, we analyse some aspects of the macro- and microscopical appearance of gonads of harbour porpoises (Phocoena phocoena) from Icelandic coastal waters. Sampling of animals bycaught in gillnets…
Review of small cetaceans: Distribution, behaviour, migration and threats
Culik, Boris
(2004)
This report summarises the available knowledge on odontocete (toothed whale) distribution, behaviour, migration and threats and was compiled for the Bonn Secretariat of CMS.
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…
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…
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…
Organochlorine residues in harbour porpoises from Southwest Greenland
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…
Updated estimates of harbour porpoise (Phocoena phocoena) bycatch in the Danish North Sea bottom-set gillnet fishery
Vinther, M.; Larsen, F.
Journal of Cetacean Research and Management (2004)
The bycatch of harbour porpoise in the Danish North Sea bottom-set gillnet fisheries between 1987-2001 is estimated using two methods involving extrapolation of observer data. When observed entanglements are extrapolated…
By-catch of harbour porpoise (Phocoena phocoena) in the lower Bay of Fundy gillnet fishery, 1998–2001
Trippel, E. A.; Shepherd, T. D.
Canadian Technical Report of Fisheries and Aquatic Sciences (2004)
The most serious threat to the status of harbour porpoise (Phocoena phocoena) is incidental mortalities caused by entanglement in fishing gear. As part of an ongoing study to evaluate the…
