Small-scale population structure of eastern North Pacific harbour porpoises (Phocoena phocoena) indicated by molecular genetic analyses
Chivers, S. J.; Dizon, A. E.; Gearin, P. J.; Robertson, K. M.
Journal of Cetacean Research and Management (2002)
Concern about the conservation and management of harbour porpoise (Phocoena phocoena) populations, which have experienced relatively large incidental fishery kills in localised areas throughout their range, has prompted research to…
Preliminary analysis of geographic variation in cranial morphometrics of the finless porpoise (Neophocaena phocaenoides)
Jefferson, T. A.
The Raffles Bulletin of Zoology (2002)
The taxonomy of the finless porpoise (Neophocaena phocaenoides), while better-studied than that of many species of small cetaceans, still suffers from some uncertainties and a general lack of data from…
Population genetic structure of finless porpoises, Neophocaena phocaenoides, in Chinese waters, inferred from mitochondrial control region sequences
Yang, Guang; Ren, Wenhua; Zhou, Kaiya; Liu, Shan; Ji, Guoqing; Yan, Jib; Wang, Limin
Marine Mammal Sci (2002)
Seven hundred and twenty base pairs (bp) of the mitochondrial control region from 73 finless porpoises, Neophocaena phocaenoides, in Chinese waters were sequenced. Thirteen variable sites were determined and 17…
Distribution and abundance of finless porpoises in Hong Kong and adjacent waters of China
Jefferson, T. A.; Hung, S. K.; Law, L.; Torey, M.; Tregenza, N.
The Raffles Bulletin of Zoology (2002)
We studied the distribution and abundance of finless porpoises (Neophocaena phocaenoides) in Hong Kong and adjacent waters of China's Guangdong Province between September 1995 and November 2000. Vessel (50,194 km)…
Mortality and morbidity of Hong Kong finless porpoises, with emphasis on the role of environmental contaminants
Jefferson, T. A.; Curry, B. E.; Kinoshita, R.
The Raffles Bulletin of Zoology (2002)
Data on causes of death for finless porpoise (Neophocaena phocaenoides) specimens stranded in Hong Kong between 1995 and 2000 were evaluated. We diagnosed several causes of death, including fishing net…
Harbour porpoise interactions with the 2001 selective salmon fisheries in southern British Columbia and license holder reported small cetacean by-catch
Hall, A.; Ellis, G.; Trites, A.W.
Selective Salmon Fisheries Science Program Report (2002)
We estimated the incidental mortality of harbour porpoise (Phocoena phocoena) in selective salmon fisheries in southern British Columbia from reports received from federal fisheries observers (2001) and license holders (1997…
Observations on behavior and ecology of the Yangtze finless porpoise (Neophocaena phocaenoides asiaeorientalis) group at Tian-e-Zhou oxbow of the Yangtze River
Wei, Z.; Wang, D.; Kuang, X.; Wang, K.; Wang, X.; Xiao, J.; Zhao, Q.; Zhang, X.
The Raffles Bulletin of Zoology (2002)
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…
Status and conservation of facultative freshwater cetaceans in Asia
Smith, B. D.; Jefferson, T. A.
The Raffles Bulletin of Zoology (2002)
Irrawaddy dolphins Orcaella brevirostris and finless porpoises Neophocaena phocaenoides are referred to as facultative freshwater cetaceans because they occupy both fresh- and nearshore marine waters. In Asia, the especially rapid…
