The Bay of Fundy/Gulf of Maine harbour porpoise (Phocoena phocoena): Some considerations regarding species interactions, energetics, density dependence and bycatch
Brodie, P.F.
Report of the International Whaling Commission (1995)
The numbers of North Atlantic harbour porpoise (Phocoena phocoena) within the Bay of Fundy/Gulf of Maine were considered to be declining as a consequence of bycatch in the sink gillnet…
Reproduction in the porpoises (Phocoenidae): Implications for management
GASKIN, D. E.; SMITH, G. J. D.; WATSON, A. P.; YASUI, W. Y.; YURICK, D. B.
Report of the International Whaling Commission (1984)
The population biology of most phocoenid species is still rather poorly understood. It is important that we improve our knowledge in view of concerns which have been expressed in recent…

African Journal of Marine Science (2007)
The distribution of harbour porpoises Phocoena phocoena in southern Europe and along the Atlantic African coast is poorly understood, with tentative assessments suggesting a discrete West African population with a…

Estimates of cetacean by-catch in the turbot fishery on the Turkish Western Black Sea Coast in 2007 and 2008
Tonay, Arda M.
Journal of the Marine Biological Association of the United Kingdom (2016)
This is the first study estimating cetacean by-catch in the Turkish western Black Sea turbot fishery. One turbot fishing boat was observed during two fishing seasons, from April through July…
Measuring the economic value of increased precision in scientific estimates of marine mammal abundance and bycatch: Harbor porpoise Phocoena phocoena in the northeast U.S. gill-net fishery
Bisack, Kathryn D.; Magnusson, Gisele
North American Journal of Fisheries Management (2014)
Marine mammal stock assessments provide information that is valuable to public sector management and the private fishing sector; however, data are costly to collect. The precautionary approach, which is widely…
A global review of porpoise (Cetacea: Phocoenidae) mortality in gillnets
Jefferson, Thomas A.; Curry, Barbara E.
Biological Conservation (1994)
A global review of mortality of porpoises in gillnet fisheries indicates that individuals of all six species become entangled and die in gillnets. Harbor porpoises Phocoena phocoena are taken throughout…
Mitochondrial control region variability of baiji and the Yangtze finless porpoises, two sympatric small cetaceans in the Yangtze river
Yang, Guang; Liu, Shan; Ren, Wenhua; Zhou, Kaiya; Wei, Fuwen
Acta Theriologica (2003)
Baiji Lipotes vexillifer (Miller, 1918) and the Yangtze finless porpoise Neophocaena phocaenoides asiaeorientalis (Pilleri and Gihr, 1972) are two sympatric small cetaceans inhabiting the middle and lower reaches of the…
