This paper presents an updated analysis of trends in the abundance of harbour porpoise, Phocoena phocoena, in central and northern California, for the period 1986-95. The most recent survey effort…
Mitigation of harbour porpoise (Phocoena phocoena) by-catch in the gillnet fishery in the lower Bay of Fundy
Trippel, Edward A.; Strong, Michael B.; Terhune, John M.; Conway, Jeremy D.
Canadian Journal of Fisheries and Aquatic Sciences (1999)
Demersal gill nets equipped with acoustic alarms reduced harbour porpoise (Phocoena phocoena) by-catch rates by 77% over those without alarms in the Swallowtail area of the lower Bay of Fundy…
A note on cephalopods from the stomachs of Dall’s porpoises (Phocoenoides dalli) from the Northwestern Pacific and Bering Sea, 1978-1982
Fiscus, C. H.; Jones, L. L.
Journal of Cetacean Research and Management (1999)
Cephalopod prey were identified from the stomachs of 100 Dall's porpoise (Phocoenoides dalli) incidentally taken by commercial salmon gillnets and research vessels from 1978 to 1982 in the western North…
Bycatches of harbour porpoises (Phocoena phocoena L.) in Danish set-net fisheries
Vinther, M.
Journal of Cetacean Research and Management (1999)
Data on bycatch of harbour porpoise (Phocoena phocoena L.) in the commercial Danish set-net fisheries were sampled from 5,591km nets in the period 1992 to 1998 using independent observers. A…
Phylogeography, intraspecific structure and sex-biased dispersal of Dall’s porpoise, Phocoenoides dalli , revealed by mitochondrial and microsatellite DNA analyses
Escorza-Treviño, S.; Dizon, A. E.
Molecular Ecology (2000)
Mitochondrial DNA (mtDNA) control-region sequences and microsatellite loci length polymorphisms were used to estimate phylogeographical patterns (historical patterns underlying contemporary distribution), intraspecific population structure and gender-biased dispersal of Phocoenoides dalli…
A preliminary study on the variability of the mitochondrial DNA control region in populations of finless porpoises (Neophocaena phocaenoides) in Chinese waters
Yang, Guang; Zhou, Kaiya
Biology and Conservation of Freshwater Cetaceans in Asia (2000)
The mitochondrial DNA control region of 12 finless porpoises (Neophocaena phocaenoides) from the Yangtze River, Yellow Sea, and South China Sea, was amplified. Two portions, 317 and 245 base pairs,…
Post-mortem investigations on stranded dolphins and porpoises from Hong Kong waters
Parsons, E. C. M.; Jefferson, T. A.
Journal of Wildlife Diseases (2000)
Stranded cetaceans reported from the territorial waters of Hong Kong during the period May 1993 to March 1998 were examined to establish factors that may have contributed to their death.…
Effects of water development on river cetaceans in China
Liu, Renjun; Wang, Ding
Biology and Conservation of Freshwater Cetaceans in Asia (2000)
Water development projects, including dams, embankments, and ship locks, have had extensive deleterious effects on two species of river cetacean in China: the baiji (Lipotes vexillifer) and the Yangtze population…
Diving behavior and swimming speed of a free-ranging harbor porpoise, Phocoena phocoena
Otani, Seiji; Naito, Yasuhiko; Kato, Akiko; Kawamura, Akito
Marine Mammal Sci (2000)
(...) Our understanding of cetacean diving behavior has recently increased (Westgate et al. 1995, Heide-Jorgensen and Dietz 1995, Davis et al. 1996). However, there are few reports which measured swim…
