Will harbour porpoises (Phocoena phocoena) habituate to pingers?
Cox, T. M.; Read, A. J.; Solow, A.; Tregenza, N.
Journal of Cetacean Research and Management (2001)
Large bycatches of harbour porpoises (Phocoena phocoena) occur in gillnet fisheries throughout the Northern Hemisphere. Several mitigation measures, including acoustic deterrent devices or ‘pingers’, have been used in efforts to…
Reactions of harbor porpoises Phocoena phocoena and herring Clupea harengus to acoustic alarms
Culik, B.M.; Koschinski, S.; Tregenza, N.; Ellis, G.M.
Marine Ecology Progress Series (2001)
Small cetaceans are susceptible to incidental mortality in the various forms of gillnet fisheries throughout their range. Research conducted since 1994 has shown that acoustic alarms (pingers) emitting high-frequency pulsed…
Age, length and reproductive parameters of harbour porpoises Phocoena phocoena (L.) from West Greenland
Lockyer, C.; Heide-Jørgensen, M. P.; Jensen, J.; Kinze, C. C.; Buus Sørensen, T.
ICES Journal of Marine Science (2001)
During 1988, 1989 and 1995, 187 harbour porpoises (Phocoena phocoena) were sampled from the catches off West Greenland during the months of July, August and September. The samples were taken…

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…

Marine Mammal Sci (2000)
Between 1991 and 1993, Alaska harbor porpoise (Phocoena phocoena) abundance was investigated during aerial surveys throughout much of the coastal and offshore waters from Bristol Bay in the eastern Bering…
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…
