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…
Influence of anthropogenic activities on marine mammal strandings in the estuary and northwestern Gulf of St. Lawrence, Quebec, Canada, 1994–2008
Truchon, M.-H.; Measures, L.; Brêthes, J.-C.; Albert, É.; Michaud, R.
Journal of Cetacean Research and Management (2018)
Stranding records have long been used to monitor marine mammal mortalities and to help identify threats to populations. In coastal areas, marine mammals face numerous anthropogenic threats such as marine…
The bacterial diversity in infected tissue pus of an East Asian finless porpoise
Wu, Caiwen; Hong, Zhe; Ibrahim, Aamir; Zhang, Di; Wang, Lin; Li, Ting; Chen, Bingyao
African Journal of Microbiology Research (2019)
Two East Asian finless porpoises (Neophocaena asiaeorientalis sunameri) in Ningbo, East China Sea, China, were observed to be bacterially infected between the fat layer and muscle layer. The microbial communities…
Phthalate metabolites in harbor porpoises (Phocoena phocoena) from Norwegian coastal waters
Rian, May Britt; Vike-Jonas, Kristine; Gonzalez, Susana Villa; Ciesielski, Tomasz Maciej; Venkatraman, Vishwesh; Lindstrøm, Ulf; Jenssen, Bjørn Munro; Asimakopoulos, Alexandros G.
Environment International (2020)
The exposure of marine mammals to phthalates has received considerable attention due to the ubiquitous occurrence of these pollutants in the marine environment and their potential adverse health effects. The…
Population structure of bycaught harbour porpoise (Phocoena phocoena) in Norway
Quintela, María; Besnier, François; Seliussen, Bjørghild; Glover, Kevin A.; Lindstrøm, Ulf
Marine Biology Research (2020)
The preference for coastal habitats makes the harbour porpoise, Phocoena phocoena, vulnerable to fisheries conflicts and hence prone to die due to entangling in fishing nets. An opportunistic sampling of…
External morphology and weight-length relationships (WLRs) of harbour porpoise, Phocoena phocoena (Cetacea: Phocoenidae) in the Black Sea
Bilgin, Sabri; Kose, Ozay; Yesilcicek, Tuncay
Turkish Journal of Fisheries and Aquatic Sciences (2020)
The present study summarized information on the morphometric characteristics and weight-length relationships (WLRs) of pregnant females, non-pregnant females and males of harbour porpoise, Phocoena phocoena (Linnaeus, 1758) along the Rize…
Using pingers to reduce bycatch of small cetaceans in Peru’s small-scale driftnet fishery
Mangel, Jeffrey C.; Alfaro-Shigueto, Joanna; Witt, Matthew J.; Hodgson, David J.; Godley, Brendan J.
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…
Pingers reduce the activity of Burmeister’s porpoise around small-scale gillnet vessels
Clay, T. A.; Alfaro-Shigueto, J.; Godley, B. J.; Tregenza, N.; Mangel, J. C.
Marine Ecology Progress Series (2019)
Incidental mortality (bycatch) in gillnet fisheries is a major threat to many cetacean populations. Acoustic alarms or pingers are a widely adopted management tool used to deter dolphins and porpoises…
