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…
Genetic population structure of harbour porpoises (Phocoena phocoena) in the North Sea and Norwegian waters
Tolley, K. A.; Rosel, P. E.; Walton, M.; Bjorge, A.; Oien, N.
Journal of Cetacean Research and Management (1999)
The harbour porpoise (Phocoena phocoena) is subject to a high rate of incidental mortality in fisheries worldwide and, in some areas, these rates are sufficiently high to warrant concern over…
Mitochondrial DNA variation in the critically endangered vaquita Phocoena sinus Norris and MacFarland, 1958
Rosel, Patricia E.; Rojas-Bracho, Lorenzo
Marine Mammal Sci (1999)
The vaquita, Phocoena sinus, is one of two critically endangered cetacean species, and is listed as an endangered species in both the United States and Mexico. These listings result from…

Van Waerebeek, Koen; Van Bressem, Marie-Françoise; Alfaro-Shigueto, Joanna; Sanino, Gian Paolo; Montes, David; Ontón, Karina
Scientific Committee Meeting Documents (1999)
Limited monitoring of 30 fishing ports on the central and northern Peruvian coast, from 03º29’S to 14º10’S, in the period 1995-99, yielded evidence of small cetacean exploitation in 25 ports…
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,…
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…
Vaquita bycatch in Mexico’s artisanal gillnet fisheries: Driving a small population to extinction
D'agrosa, Caterina; Lennert-Cody, Cleridy E.; Vidal, Omar
Conservation Biology (2000)
The world's most endangered marine cetacean, the vaquita (Phocoena sinus), continues to be caught in small-mesh gillnet fisheries throughout much of its range. We monitored fishing effort and incidental vaquita…
Radio tracking finless porpoises (Neophocaena phocaenoides): Preliminary evaluation of a potential technique, with cautions
Würsig, B.; Wang, D.; Zhang, X.
Biology and Conservation of Freshwater Cetaceans in Asia (2000)
Three finless porpoises (Neophocaena phocaenoides) from the Yangtze River were fitted with cotton cloth vests and small radio transmitters. They were tracked for 2.6, 11.0, and 14.6 days in the…
The effects of acoustic alarms on the behavior of harbor porpoises (Phocoena phocoena) in a floating pen
Kastelein, R. A.; Rippe, H. T.; Vaughan, N.; Schooneman, N. M.; Verboom, W. C.; De Haan, D.
Marine Mammal Sci (2000)
In an attempt to test the effectiveness of sounds in deterring harbor porpoises from nets and reducing porpoise bycatch in gill net fisheries, two harbor porpoises, kept in a large…
Status and conservation of the Yangtze finless porpoise
Wang, Ding; Liu, Renjun; Zhang, Xianfeng; Yang, Jian; Wei, Zhuo; Zhao, Qingzhong; Wang, Xiaoqiang
Biology and Conservation of Freshwater Cetaceans in Asia (2000)
During 1991–1997, five and three surveys were conducted in the middle and lower reaches, respectively, of the Yangtze River. The target species of the surveys included both the baiji (Lipotes…
