Determining optimal pinger spacing for harbour porpoise bycatch mitigation

Larsen, F.; Krog, C.; Ritzau Eigaard, O.
Endangered Species Research (2013)

A trial was conducted in the Danish North Sea hake gillnet fishery in July to September 2006 to determine whether the spacing of the Aquatec AQUAmark100 pinger could be increased…

Possible causes of a harbour porpoise mass stranding in Danish waters in 2005

Wright, Andrew J.; Maar, Marie; Mohn, Christian; Nabe-Nielsen, Jacob; Siebert, Ursula; Jensen, Lasse Fast; Baagøe, Hans J.; Teilmann, Jonas
PLoS ONE (2013)

An unprecedented 85 harbour porpoises stranded freshly dead along approximately 100 km of Danish coastline from 7–15 April, 2005. This total is considerably above the mean weekly stranding rate for…

Synthetic communication signals influence wild harbour porpoise (Phocoena phocoena) behaviour

Culik, Boris; von Dorrien, Christian; Müller, Vailett; Conrad, Matthias
Bioacoustics (2015)

We used our novel and programmable Porpoise Alarm (PAL, patd.) to synthesize life-like, electronic harbour porpoise communication signals based on those described for captive animals. In the Little Belt, Denmark,…

Tregenza, N.J.C.; Berrow, S. D.; Hammond, P. S.; Leaper, R.
ICES Journal of Marine Science (1997)

A programme to assess the cetacean by-catch in the Irish and UK set gillnet fisheries in the Celtic Sea was conducted from August 1992 to March 1994 using volunteer observers.…

Eat and be eaten – Porpoise diet studies

Leopold, Maarten Frederik
Doctoral Thesis - Wageningen University (2015)

1. Diet studies of marine mammals typically summarise prey composition across all individuals studied. Variation in individual diets is usually ignored, but may be more than just “noise” around an…

Gerrodette, Tim; Rojas-Bracho, Lorenzo
Marine Mammal Science (2011)

Bycatch in artisanal gill nets threatens the vaquita, Phocoena sinus, with extinction. In 2008 the Mexican government announced a conservation action plan for this porpoise, with three options for a…

Analysis of the artisanal fisheries of San Felipe, Mexico: Estimating incidental mortality of the vaquita (Phocoena sinus)

Urrutia-Osorio, M. Fernanda; Jaramillo-Legorreta, Armando M.; Rojas-Bracho, Lorenzo; Sosa-Nishizaki, Oscar
Journal of Marine Animals and Their Ecology (2015)

The vaquita (Phocoena sinus) is the most critically endangered cetacean species in the world and is a small porpoise endemic to the northern Gulf of California, Mexico. As fishing efforts…

Records of harbour porpoises (Phocoena phocoena) in fishing nets during the interwar period in Poland: Verification of archival materials

Psuty, Iwona
Aquatic Mammals (2013)

The Polish fisheries administration registered incidents of harbour porpoises caught by fishermen from fishing bases within the country's borders between 1922 and 1938. These data are unique in the Baltic…

Skora, K. E.; Pawliczka, I.; Klinowska, M.
Aquatic Mammals (1988)

Information on the harbour porpoise in Polish waters is reviewed and a corrected and updated list of catches, strandings and sightings given. The number of records per year has changed…
