Oryx (2013)
There is growing awareness that small-scale fisheries may have large impacts on threatened marine fauna. Bycatch of small cetaceans by the Peruvian small-scale driftnet fleet results in the deaths of…
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…
Effects of noise and by-catch on a Danish harbour porpoise population
Nabe-Nielsen, Jacob; Sibly, Richard M.; Tougaard, Jakob; Teilmann, Jonas; Sveegaard, Signe
Ecological Modelling (2014)
Ships and wind turbines generate noise, which can have a negative impact on marine mammal populations by scaring animals away. Effective modelling of how this affects the populations has to…
Measuring the economic value of increased precision in scientific estimates of marine mammal abundance and bycatch: Harbor porpoise Phocoena phocoena in the northeast U.S. gill-net fishery
Bisack, Kathryn D.; Magnusson, Gisele
North American Journal of Fisheries Management (2014)
Marine mammal stock assessments provide information that is valuable to public sector management and the private fishing sector; however, data are costly to collect. The precautionary approach, which is widely…
Pingers cause temporary habitat displacement in the harbour porpoise Phocoena phocoena
Kyhn, L. A.; Jørgensen, P. B.; Carstensen, J.; Bech, N. I.; Tougaard, J.; Dabelsteen, T.; Teilmann, J.
Marine Ecology Progress Series (2015)
Several studies have shown that pingers mitigate porpoise bycatch and thus pinger use is now mandatory in some fisheries—although the long-term effects of pinger exposure on porpoises have not been…
Strandings, bycatches and injuries of aquatic mammals in China, 2000–2006, as reviewed from official documents: A compelling argument for a nationwide strandings programme
Wang, Yamin; Li, Wei; Van Waerebeek, Koen
Marine Policy (2015)
In the present study, the species composition, geographical and seasonal patterns of strandings, bycatches and injuries of aquatic mammals reported in Chinese mainland waters, from 2000 to 2006, were analyzed…
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…
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…
Cetacean distribution in the southern Black Sea: An acoustic approach
Saydam, Gülce
Master's Thesis - Middle East Technical University (2015)
Large numbers of small cetaceans (common dolphin, harbor porpoises and bottlenose dolphins) were hunted in the Black Sea until the hunting of cetaceans was banned in Turkey in 1983. Even…
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,…
