Fishery Bulletin (1998)
We examined 107 harbor porpoise (Phocoena phocoena) carcasses recovered from beaches in Maryland, Virginia, and North Carolina between 1994 and 1996 for evidence of entanglement in fishing gear. Stranded porpoises…
Target detection by an echolocating harbor porpoise (Phocoena phocoena)
Kastelein, R. A.; Au, W. W. L.; Rippe, H. T.; Schooneman, N. M.
The Journal of the Acoustical Society of America (1999)
Two echolocation experiments are described. They were conducted on the same harbor porpoise housed in a sea pen, one year apart at Neeltje Jans, The Netherlands. The aims were to…
Risk factors affecting the vaquita (Phocoena sinus)
Rojas-Bracho, Lorenzo; Taylor, Barbara L.
Marine Mammal Sci (1999)
Despite the vaquita being commonly cited as one of the most endangered marine mammals in the world, there is still disagreement over which factors put the species at greatest risk…
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…
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…
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…

We succinctly review and document new cases of diseases of the skin and the skeletal system and external traumata in cetaceans from Ecuador, Colombia, Peru, Chile, Argentina, Uruguay, Brazil, and…
Comparison of echolocation behaviour between coastal and riverine porpoises
Akamatsu, Tomonari; Teilmann, Jonas; Miller, Lee A.; Tougaard, Jakob; Dietz, Rune; Wang, Ding; Wang, Kexiong; Siebert, Ursula; Naito, Yasuhiko
Deep Sea Research Part II: Topical Studies in Oceanography (2007)
Echolocation behaviour of a harbor porpoise and six finless porpoises was recorded in open-water systems using acoustic data loggers (A-tag). In total 1359 click trains were recorded during 4.6 h…
Saving the Vaquita: Immediate action, not more data
JARAMILLO-LEGORRETA, ARMANDO; ROJAS-BRACHO, LORENZO; BROWNELL, ROBERT L.; READ, ANDREW J.; REEVES, RANDALL R.; RALLS, KATHERINE; TAYLOR, BARBARA L.
Conservation Biology (2007)
The recent likely extinction of the baiji (Chinese river dolphin [Lipotes vexillifer]) (Turvey et al. 2007) makes the vaquita (Gulf of California porpoise [Phocoena sinus]) the most endangered cetacean. The…
Potential limits to anthropogenic mortality of small cetaceans in coastal waters of British Columbia
Williams, Rob; Hall, Anna; Winship, Arliss
Can. J. Fish. Aquat. Sci. (2008)
Small cetaceans are by-caught in salmon gillnet fisheries in British Columbia (BC) waters. In Canada, there is currently no generic calculation to identify when management action is necessary to reduce…
