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)

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…


Evaluating management strategies for marine mammal populations: An example for multiple species and multiple fishing sectors in Iceland

Punt, André E; Siple, Margaret; Sigurðsson, Guðjón M.; Víkingsson, Gisli; Francis, Tessa B.; Granquist, Sandra Magdalena; Hammond, Philip S; Heinemann, Dennis; Long, Kristy J.; Moore, Jeffrey E.; Sepúlveda, Maritza; Reeves, Randall R.; Wade, Paul R.; Williams, Rob; Zerbini, Alexandre N.
Canadian Journal of Fisheries and Aquatic Sciences (2020)

A Management Strategy Evaluation is used to estimate success at achieving conservation goals for marine mammals while also aiming to minimize impacts on commercial fisheries. It is intended to improve…

Biological Conservation (2020)

The Yangtze finless porpoise (Neophocaena asiaeorientalis asiaeorientalis), has experienced rapid declines in recent decades. We estimate its abundance based on surveys conducted between November and December 2017 in the main-stem…


Underwater noise pollution in China’s Yangtze River critically endangers Yangtze finless porpoises (Neophocaena asiaeorientalis asiaeorientalis)

Environmental Pollution (2020)

Underwater sound plays an important role in some critical life functions of many aquatic animals. Underwater noise pollution has received relatively more attention in ocean systems. However, little attention has…


Using passive acoustic monitoring to investigate the occurrence of cetaceans in a protected marine area in northwest Ireland

Todd, Nicole R. E.; Cronin, Michelle; Luck, Cian; Bennison, Ashley; Jessopp, Mark; Kavanagh, Ailbhe S.
Estuarine, Coastal and Shelf Science (2020)

Under the EU Habitats Directive, cetacean species must be maintained at favourable conservation status in European waters. Whether this is achieved via protected area designation, curtailment of activities such as…


Habitat succession of the Yangtze finless porpoise in Poyang Lake under the changing hydrodynamic and feeding environment

Han, Yong; Sun, Zhiyu; Fang, Hongwei; Bai, Sen; Huang, Lei; He, Guojian
Ecological Modelling (2020)

Poyang Lake, located in the middle and lower reaches of the Yangtze River, is the largest freshwater lake in China and the most important habitat for the Yangtze finless porpoise.…


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…
