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…
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…
Report of the Eleventh meeting of the Comité Internacional para la Recuperación de la Vaquita (CIRVA)
(2019)
The members of the International Committee for the Recovery of the Vaquita (CIRVA), a group that has advised the Government of Mexico on the conservation of this species since 1997,…
Saving the vaquita one bite at a time: The missing role of the shrimp consumer in vaquita conservation
Dunch, Victoria
Marine Pollution Bulletin (2019)
The vaquita (Phocoena sinus) is the world's smallest cetacean and most endangered marine mammal. The species is under threat from illegal fishing activities that take place in the upper Gulf…
Differential population dynamics of a coastal porpoise correspond to the fishing effort in a large estuarine system

Aquatic Conservation: Marine and Freshwater Ecosystems (2019)
The finless porpoise (genus Neophocaena) is susceptible to fishery‐caused mortality, and its numbers are thought to be in decline across its entire range. However, population demographics have rarely been quantified…
Decline towards extinction of Mexico’s vaquita porpoise (Phocoena sinus)
Jaramillo-Legorreta, Armando M.; Cardenas-Hinojosa, Gustavo; Nieto-Garcia, Edwyna; Rojas-Bracho, Lorenzo; Thomas, Len; Ver Hoef, Jay M.; Moore, Jeffrey; Taylor, Barbara; Barlow, Jay; Tregenza, Nicholas
Royal Society Open Science (2019)
The vaquita (Phocoena sinus) is a small porpoise endemic to Mexico. It is listed by IUCN as Critically Endangered because of unsustainable levels of bycatch in gillnets. The population has…
Food for thought: Harbor porpoise foraging behavior and diet inform vulnerability to disturbance
Booth, Cormac G.
Marine Mammal Science (2019)
Research has shown that noise disturbance can disrupt the behavior of harbor porpoises. The significance of such disturbance is unclear. However, these animals may be vulnerable to starvation when disturbed…

Endangered Species Research (2019)
In 2017 an emergency field effort was undertaken in an attempt to prevent the extinction of the world’s most endangered marine mammal, the vaquita (Phocoena sinus). The rescue effort involved…
Records of harbour porpoise (Phocoena phocoena) in the mouth of the Douro River (northern Portugal) with presence of an anomalous white individual
Gil, Ágatha; Correia, Ana M.; Sousa-Pinto, Isabel
Marine Biodiversity Records (2019)
Harbour porpoise (Phocoena phocoena) is listed under the Annex II of the European Habitats Directive (Directive 92/43/CEE) and Member States are required to designate special areas of conservation to protect…
Porpoises the world over: Diversity in behavior and ecology
Teilmann, Jonas; Sveegaard, Signe
Ethology and Behavioral Ecology of Odontocetes (2019)
Unlike the large number of species of true dolphins, there are only seven porpoise or phocoenid species, inhabiting different habitats and climate zones. They range from ice-covered water in the…
