Rapid changes of marine ecosystems resulting from human activities and climate change, and the subsequent reported rise of infectious diseases in marine mammals, highlight the urgency for timely detection of…
Making nets more acoustically visible: Floats as passive mitigation measures to reduce bycatch of harbour porpoise (Phocoena phocoena) in gillnets
Rosshagen, F.
(2023)
Incidental capture in fishing gear is today affecting at least 112 marine mammal species worldwide and for many smaller toothed whale species (Odontocete), gillnets are considered to be the largest…

The Shandong Peninsula is located on the western coast of the Pacific and is adjacent to the Bohai Sea (BS) and the Yellow Sea (YS) to the east. The East…
Harbor porpoise losing its edge: Genetic time series suggests a rapid population decline in Iberian waters over the last 30 years
Ben Chehida, Yacine; Stelwagen, Tjibbe; Hoekendijk, Jeroen P. A.; Ferreira, Marisa; Eira, Catarina; Torres‐Pereira, Andreia; Nicolau, Lidia; Thumloup, Julie; Fontaine, Michael C.
Ecology and Evolution (2023)
Impact of climate change is expected to be especially noticeable at the edges of a species' distribution, where they meet suboptimal habitat conditions. In Mauritania and Iberia, two genetically differentiated…
Recent progress and future directions for conservation of the Yangtze finless porpoise (Neophocaena asiaorientalis asiaorientalis)
Hao, Yujiang; Nabi, Ghulam; Mei, Zhigang; Zheng, Jinsong; Wang, Kexiong; Wang, Ding
Der Zoologische Garten (2023)
With the functional extinction of the Yangtze River dolphin or baiji (Lipotes vexillifer) based on the survey conducted in 2006, the Yangtze finless porpoise (Neophocaena asiaorientalis) is now the only…
An overview of the status of sturgeons and cetaceans accidentally captured in southern Black Sea coastal zone of Türkiye
Özdemir, Süleyman; Erdem, Ercan; Birinci Özdemir, Zekiye
Marine Science and Technology Bulletin (2023)
This study was conducted out in the southern Black Sea coastal zone, in 2011-2016 fishing seasons. In the study, bycatch of sturgeons and cetaceans were examined both in small scale…
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…
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…
Assessing the effects of banana pingers as a bycatch mitigation device for harbour porpoises (Phocoena phocoena)
Omeyer, Lucy C. M.; Doherty, Philip D.; Dolman, Sarah; Enever, Robert; Reese, Allan; Tregenza, Nicholas; Williams, Ruth; Godley, Brendan J.
Frontiers in Marine Science (2020)
Bycatch is a significant cause of population declines of marine megafauna globally. While numerous bycatch mitigation strategies exist, acoustic alarms, or pingers, are the most widely adopted strategy for small…
Determination of optimal acoustic passive reflectors to reduce bycatch of odontocetes in gillnets
Kratzer, Isabella M. F.; Schäfer, Ingo; Stoltenberg, Arne; Chladek, Jérôme C.; Kindt-Larsen, Lotte; Larsen, Finn; Stepputtis, Daniel
Frontiers in Marine Science (2020)
The need to minimize bycatch of toothed whales (odontocetes) in gillnets has long been recognized, because they are often top predators and thus essential to ecosystem resilience. It is likely…
