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…
A field effort to capture critically endangered vaquitas Phocoena sinus for protection from entanglement in illegal gillnets
Rojas-Bracho, L.; Gulland, F. M. D.; Smith, C. R.; Taylor, B.; Wells, R. S.; Thomas, P. O.; Bauer, B.; Heide-Jørgensen, M. P.; Teilmann, J.; Dietz, R.; Balle, J. D.; Jensen, M. V.; Sinding, M. H.

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…
Eighth Meeting of the Comité Internacional para la Recuperación de la Vaquita
CIRVA
(2017)
The Dire Status of the Vaquita Has Worsened Analysis of the 2016 Acoustic Monitoring Program data has shown that almost half of the remaining vaquita population was lost between 2015…
Long-term tag retention on two species of small cetaceans
Heide-Jørgensen, Mads Peter; Nielsen, Nynne H.; Teilmann, Jonas; Leifsson, Páll S.
Marine Mammal Science (2017)
The effects of tagging on small cetaceans are difficult to assess due to logistical difficulties in recapturing the whales. In this study two narwhals, Monodon monoceros, and five harbor porpoises,…
Fishers’ knowledge as an information source to investigate bycatch of marine mammals in the South China Sea
Liu, M.; Lin, M.; Turvey, S. T.; Li, S.
Animal Conservation (2016)
Bycatch mortality is a significant driver of marine mammal population declines. However, there is little information available on patterns or magnitude of bycatch mortality in many heavily fished Asian marine…
Seventh Meeting of the Comité Internacional para la Recuperación de la Vaquita
CIRVA
(2016)
EXTINCTION IS IMMINENT CIRVA reviewed the 2015 population survey results, which showed that only about 60 vaquitas remained at the beginning of the emergency 2-year partial gillnet ban. CIRVA also…
Molecular identification of small cetacean samples from Peruvian fish markets
Tzika, Athanasia C.; D’Amico, Eva; Alfaro-Shigueto, Joanna; Mangel, Jeffrey C.; Van Waerebeek, Koen; Milinkovitch, Michel C.
Conservation Genetics (2010)
In the last 60 years, incidental entanglement in fishing gears (so called by-catch) became the main cause of mortality worldwide for small cetaceans and is pushing several populations and species…
Small cetacean captures in Peruvian artisanal fisheries: High despite protective legislation
Mangel, Jeffrey C.; Alfaro-Shigueto, Joanna; Van Waerebeek, Koen; Cáceres, Celia; Bearhop, Stuart; Witt, Matthew J.; Godley, Brendan J.
Biological Conservation (2010)
We detail the first direct, at sea monitoring of small cetacean interactions with Peruvian artisanal drift gillnet and longline fisheries. A total of 253 small cetaceans were captured during 66…
Physiological responses to capture and handling of free-ranging male Yangtze finless porpoises (Neophocaena phocaenoides asiaeorientalis)
Hao, Yu-Jiang; Zhao, Qing-Zhong; Wu, Hai-Ping; Chen, Dao-Quan; Gong, Cheng; Li, Li; Wang, Ding
Marine and Freshwater Behaviour and Physiology (2009)
We captured free-ranging male Yangtze finless porpoises over three seasons and assayed leukocytes and serum biochemistry to investigate physiological responses to the capture and handlings. Serum thyroid hormones (THs) declined…
Small cetacean captures and CPUE estimates in artisanal fisheries operating from a port in northern Peru, 2005-2007
Alfaro-Shigueto, Joanna; Mangel, Jeffrey C.; Van Waerebeek, Koen
Scientific Committee Meeting Documents (2008)
This work provides the first direct, at-sea monitoring of small cetacean interactions with Peruvian artisanal drift gillnet and longline vessels. A total of 253 small cetaceans were observed captured during…
