The numbers of North Atlantic harbour porpoise (Phocoena phocoena) within the Bay of Fundy/Gulf of Maine were considered to be declining as a consequence of bycatch in the sink gillnet…
Report of the International Whaling Commission (1995)
Specimens of harbour porpoises, Phocoena phocoena, from strandings and bycatches in fisheries around the British Isles between 1985 and September 1994 have been examined. Full autopsies were undertaken on most…
Report of the International Whaling Commission (1995)
Specimens of harbour porpoises, Phocoena phocoena, from both strandings and bycatch in fisheries around the United Kingdom between 1985 and 1994 have been examined. Full autopsies were undertaken on most…
Report of the International Whaling Commission (1995)
Parasite and pollutant loads, reproductive status and overall condition were recorded for seven harbour porpoise shot at the Faroes in 1987-1988. Four species of nematodes were found. A mixed infection…
Report of the International Whaling Commission (1995)
Published data on concentrations of organochlorine compounds and heavy metals in tissues of harbour porpoises from the eastern North Atlantic are reviewed. The dynamics of pollutants in this population are…
