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…
Fifteen fishing centres on the northern and central coasts of Peru, including large industrial fishing ports and smaller fish landing sites were surveyed for cetacean landings periodically over 29 months,…
Data on causes of death for finless porpoise (Neophocaena phocaenoides) specimens stranded in Hong Kong between 1995 and 2000 were evaluated. We diagnosed several causes of death, including fishing net…
Irrawaddy dolphins Orcaella brevirostris and finless porpoises Neophocaena phocaenoides are referred to as facultative freshwater cetaceans because they occupy both fresh- and nearshore marine waters. In Asia, the especially rapid…
Between the years 1990 and 2000, an attempt was made to determine the causes of death of 55 harbour porpoises stranded along the Belgian and northern French coasts. From 1990…
From 5 March to 1 July, 1999 and 2000, we made six shipboard surveys for finless porpoises (Neophocaena phocaenoides) in the Inland Sea, which is believed to be inhabited by…
Between 1991 and 1996, necropsies were performed on 445 harbour porpoises (Phocoena phocoena), in various states of preservation, stranded on German coasts or accidentally caught by German fishermen. The animals…
Serious concerns have been raised regarding the status of the harbour porpoise populations in the North Atlantic and specifically for those inhabiting Atlantic Canadian waters. In 1991 harbour porpoise in…
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…
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…
