This paper presents information on the distribution of harbour porpoise in Norwegian coastal and adjacent waters based on incidental sightings during the period 1964-1968, bycatches in the driftnet salmon fishery…
Effects of Beaufort sea state heterogeneities on density estimates of harbor porpoises from data collected during 'independent' team line transect sighting surveys are investigated. The surveys were conducted in the…
This paper summarises current knowledge of the three populations of harbour porpoises in US and Canadian Atlantic waters. During the summer, the populations are centred in the Gulf of Maine/Bay…
A comparison of the acoustic waveforms of three different species, Phocoena phocoena, Phocoena sinus and Neophocaena phocaenoides of the sub-family Phocoeninae is made with the species Phocoenoides dalli of the…
The majority (63%) of harbour porpoises stranded around the Moray Firth, Scotland, died from trauma characterized by multiple skeletal fractures and damaged internal organs. Surface injuries consisted of skin cuts…
Our estimates of total harbour porpoise bycatch in the Gulf of Maine sink gillnet fishery for 1990 to 1993, with 95% confidence intervals in brackets, are 2,900 [1,500-5 ,500], 2,000…
Biological data on the harbour porpoise in Portuguese coastal waters are scarce, mainly because of the small number of animals available for study. Nevertheless, a regular geographical distribution pattern can…
Levels of organochlorine compounds (PCDD, PCDF, PCB and organochlorine pesticides) were determined in cetaceans collected from the west coast of North America between 1986 and 1989. The samples included gray…
Harbour porpoises (Phocoena phocoena) are notoriously difficult to observe and become very difficult to see in moderate or rough sea conditions. Passive acoustic monitoring provides a complementary study method to…
Hundreds of harbor porpoise die each year as bycatch in the Gulf of Maine's sink gillnet fishery. In recent years, concern has arisen whether the Gulf of Maine population of…
