Biological Conservation (1997)
Of 722 cetaceans captured mostly in multi-filament gillnets and landed at Cerro Azul, central Peru, in 87 days during January–August 1994, 82.7% were dusky dolphin Lagenorhynchus obscurus, 12.6% Burmeister's porpoise…
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…
Documenting the bycatch of harbor porpoises, Phocoena phocoena, in coastal gillnet fisheries from stranded carcasses
Cox, T. M.; Read, A. J.; Barco, S.; Evans, J.; Gannon, D. P.; Koopman, H. N.; McLellan, W. A.; Murray, K.; Nicolas, J.; Pabst, D. A.; Potter, C. W.; Swingle, W. M.; Thayer, V. G.; Touhey, K. M.; Westgate, A. J.
Fishery Bulletin (1998)
We examined 107 harbor porpoise (Phocoena phocoena) carcasses recovered from beaches in Maryland, Virginia, and North Carolina between 1994 and 1996 for evidence of entanglement in fishing gear. Stranded porpoises…
To ping or not to ping: The use of active acoustic devices in mitigating interactions between small cetaceans and gillnet fisheries
Dawson, S. M.; Northridge, S.; Waples, D.; Read, A. J.
Endangered Species Research (2013)
Active sound emitters (‘pingers’) are used in several gillnet fisheries to reduce bycatch of small cetaceans, and/or to reduce depredation by dolphins. Here, we review studies conducted to determine how…
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…
Echolocation behavior of harbor porpoises Phocoena phocoena around chemically enhanced gill nets
Cox, T. M.; Read, A. J.
Marine Ecology Progress Series (2004)
The echolocation behavior of harbor porpoises Phocoena phocoena around gillnets was monitored to test their response to chemically (BaSO4) enhanced gill nets, designed to be more acoustically reflective than commercial…
Net fisheries and net mortality of small cetaceans off Tierra del Fuego, Argentina
Goodall, R. N. P.; Schiavini, A. C. M.; Fermani, C.
Report of the International Whaling Commission (1994)
There are five basic types of inshore fishing off Argentinian Tierra del Fuego: coastal fishing with gillnets or lines along the northeastern coasts; beach seining, use of wicker pots, and…
Bycatches of the harbour porpoise (Phocoena phocoena) in the Swedish Skagerrak, Kattegat and Baltic Seas; 1973-1993
Berggren, P.
Report of the International Whaling Commission (1994)
The harbour porpoise is the only cetacean common to Swedish waters. This paper reviews data on harbour porpoise bycatches in the Swedish Skagerrak, Kattegat and Baltic Seas between 1973 and…
Summary of current knowledge of harbour porpoises in US and Canadian Atlantic waters
Palka, D. L.; Read, A. J.; Westgate, A. J.; Johnston, D. W.
Report of the International Whaling Commission (1996)
This paper summarises current knowledge of the three populations of harbour porpoises in US and Canadian Atlantic waters. During the summer, the populations are centred in the Gulf of Maine/Bay…
Incidental catches of harbour porpoises (Phocoena phocoena) in the Gulf of St. Lawrence and the St. Lawrence River Estuary, Quebec, Canada
Fontaine, P.-M.; Barrette, C.; Hammill, M. O.; Kingsley, M. C. S.
Report of the International Whaling Commission (1994)
Incidental catches of harbour porpoise by commercial fisheries in the Estuary and Gulf of St. Lawrence, Canada were examined. Two questionnaires, one in 1989 and one in 1990, were sent…
