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…
A note on radionuclide 137Cs and 40K concentrations in Dall’s porpoises, Phocoenoides dalli, in coastal waters of Japan
Kasamatsu, F.; Kawabe, K.; Inatomi, N.; Murayama, T.;
Journal of Cetacean Research and Management (1999)
Concentrations of artificial radionuclide 137Cs and natural radionuclide 40K in Dall's porpoise, Phocoenoides dalli, from the Pacific coast of northern Japan in 1996 are presented. Concentrations of 137Cs in muscle…
Application of a new method to investigate population structure in the harbour porpoise, Phocoena phocoena, with special reference to the North and Baltic Seas
Lockyer, C.
Journal of Cetacean Research and Management (1999)
Tooth ultrastructure in harbour porpoise is examined as a possible tool for differentiating between animals from different geographical regions in the North Atlantic. Nine different characteristics in both dentine and…
Experimental testing of acoustic alarms (pingers) to reduce bycatch of harbour porpoise, Phocoena phocoena, in the state of Washington
Gearin, P. J.; Gosho, M. E.; Laake, J. L.; Cooke, L.; DeLong, R. L.; Hughes, K. M.
Journal of Cetacean Research and Management (2000)
Field tests were conducted on the effectiveness of acoustic alarms (pingers) in reducing the incidental catch of harbour porpoise (Phocoena phocoena) in a salmon gillnet fishery in northern Washington in…
The use of time/area closures to reduce bycatches of harbour porpoises: lessons from the Gulf of Maine sink gillnet fishery
Murray, K. T.; Read, A. J.; Solow, A. R.;
Journal of Cetacean Research and Management (2000)
In 1994, the United States National Marine Fisheries Service (NMFS) implemented a series of time/area closures for the Gulf of Maine sink gillnet fishery to reduce the bycatch of harbour…
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…
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…
Influence of sea state on density estimates of harbour porpoises (Phocoena phocoena)
Teilmann, J.
Journal of Cetacean Research and Management (2003)
A ship-based line transect survey was conducted in the Great Belt, Denmark, from 7-20 April 1994, covering an area of 705 linear kilometres. A total of 497 sightings were collected…
Current knowledge of the cetacean fauna of the Greek Seas
Frantzis, A.; Alexiadou, P.; Paximadis, G.; Politi, E.; Gannier, A.; Corsini-Foka, M.
Journal of Cetacean Research and Management (2003)
From 1991-2002 data on the presence and distribution of cetaceans in the Greek Seas have been systematically collated in a database (821 sightings and 715 strandings). Data originated from dedicated…
