Knowing the fishery to know the bycatch: Bias-corrected estimates of harbour porpoise bycatch in gillnet fisheries

Kindt-Larsen, Lotte; Glemarec, Gildas; Berg, Casper W.; Königson, Sara; Kroner, Anne-Mette; Søgaard, Mathias; Lusseau, David
Proceedings of the Royal Society B: Biological Sciences (2023)

Incidental captures (bycatch) remain a key global conservation threat for cetaceans. Bycatch of harbour porpoise Phocoena phocoena in set gillnets is routinely monitored in European Union fisheries, but generally relies…

In this case report, we present a rare occurrence of a narrow-ridged finless porpoise (Neophocaena asiaeorientalis sunameri), discovered on the coast of Jeju Island, Republic of Korea, that was afflicted…


The click production of captive Yangtze finless porpoises (Neophocaena asiaeorientalis asiaorientalis) is influenced by social and environmental factors

Serres, Agathe; Xu, Chen; Hao, Yujiang; Wang, Ding
Animals (2021)

Yangtze finless porpoises use high-frequency clicks to navigate, forage, and communicate. The way in which click production may vary depending on social or environmental context has never been investigated. A…


Out of sight, out of mind: How conservation is failing European porpoises

Carlén, Ida; Nunny, Laetitia; Simmonds, Mark P.
Frontiers in Marine Science (2021)

The conservation of harbor porpoises (Phocoena phocoena) appears to be failing in Europe. There are particular concerns about this species in the Baltic Proper, Black, and Mediterranean Seas, as well…


First evaluation of legacy persistent organic pollutant contamination status of stranded Yangtze finless porpoises along the Yangtze River Basin, China

Science of The Total Environment (2020)

Yangtze finless porpoises (Neophocaena asiaeorientalis asiaeorientalis), inhabiting the Yangtze River, are an endangered species in China. They are threatened by various kinds of pollutants, among which persistent organic pollutants (POPs)…


Stable oxygen isotopes reveal habitat use by marine mammals in the Río de la Plata estuary and adjoining Atlantic Ocean

Drago, Massimiliano; Valdivia, Meica; Bragg, Daniel; González, Enrique M.; Aguilar, Alex; Cardona, Luis
Estuarine, Coastal and Shelf Science (2020)

Detailed knowledge on habitat use by marine mammals is critical for understanding their ecological role and for adequate management. Here, we assess the habitat use patterns of thirteen species of…


Levels of polychlorinated biphenyls are still associated with toxic effects in harbor porpoises (Phocoena phocoena) despite having fallen below proposed toxicity thresholds

Williams, Rosie; ten Doeschate, Mariel; Curnick, David J.; Brownlow, Andrew; Barber, Jonathan L.; Davison, Nicholas J.; Deaville, Robert; Perkins, Matthew; Jepson, Paul D.; Jobling, Susan
Environmental Science & Technology (2020)

Polychlorinated biphenyls (PCBs) are toxic, persistent, and lipophilic chemical compounds that accumulate to high levels in harbor porpoises (Phocoena phocoena) and other cetaceans. It is important to monitor PCBs in…
