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…
Marine mammal records from Iran
Braulik, G. T.; Ranjbar, S.; Owfi, F.; Aminrad, T.; Dakhteh, S. M. H.; Kamrani, E.; Mohsenizadeh, F.
Journal of Cetacean Research and Management (2010)
Iran has 1,700km of coastline that borders the Persian Gulf and the Arabian Sea in the northwest Indian Ocean. Apart from a handful of records, almost nothing is known about…
Changes in click source levels with distance to targets: Studies of free-ranging white-beaked dolphins Lagenorhynchus albirostris and captive harbour porpoises Phocoena phocoena
Atem, Ana Carolina G.; Rasmussen, Marianne H.; Wahlberg, Magnus; Petersen, Hans C.; Miller, Lee A.;
Bioacoustics (2009)
Probably all odontocetes use echolocation for spatial orientation and detection of prey. We used a four hydrophone “Y” array to record the high frequency clicks from free-ranging White-beaked Dolphins Lagenorhynchus…
Epidemiological pattern of tattoo skin disease: A potential general health indicator for cetaceans
Van Bressem, M. F.; Van Waerebeek, K.; Aznar, F. J.; Raga, J. A.; Jepson, P. D.; Duignan, P.; Deaville, R.; Flach, L.; Viddi, F.; Baker, J. R.; Di Beneditto, A. P.; Echegaray, M.; Genov, T.; Reyes, J.; Felix, F.; Gaspar, R.; Ramos, R.; Peddemors, V.; Sanino, G. P.; Siebert, U.
Diseases of Aquatic Organisms (2009)
The presence of tattoo skin disease (TSD) was examined in 1392 free-ranging and dead odontocetes comprising 17 species from the Americas, Europe, South Africa, New Zealand and Greenland. We investigated…
Potential limits to anthropogenic mortality of small cetaceans in coastal waters of British Columbia
Williams, Rob; Hall, Anna; Winship, Arliss
Can. J. Fish. Aquat. Sci. (2008)
Small cetaceans are by-caught in salmon gillnet fisheries in British Columbia (BC) waters. In Canada, there is currently no generic calculation to identify when management action is necessary to reduce…
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…
Emission of social sounds by marine animals
Au, W. W. L.; Hastings, M. C.
Principles of Marine Bioacoustics (2008)
(...) Sound emissions by odontocetes (toothed whales and dolphins) can be classified into two broad categories of frequency-varying continuous tonal sounds referred to as whistles and broadband clicks (Evans, 1967),…
Skin diseases in cetaceans
Van Bressem, Marie-Françoise; Van Waerebeek, Koen; Flach, Leonardo; Reyes, Julio César; de Oliveira Santos, Marcos César; Siciliano, Salvatore; Echegaray, Monica; Viddi, Francisco; Felix, Fernando; Crespo, Enrique; Sanino, Gian Paolo; Avila, Isabel Cristina; Fraijia, Natalia; Castro, Cristina
Scientific Committee Meeting Documents (2008)
Micro-organisms that are known or suspected to cause skin diseases in cetaceans are briefly reviewed. Viruses belonging to four families i.e. Caliciviridae, Herpesviridae, Papillomaviridae and Poxviridae were detected by electron…
Changes in the occurrence of common dolphins, striped dolphins and harbour porpoises in the English Channel and Bay of Biscay
MacLeod, Colin D.; Brereton, Tom; Martin, Clive
Journal of the Marine Biological Association of the United Kingdom (2008)
Regular monitoring of the status of cetacean populations is essential for conservation, policy and management. By using a passenger ferry as a scientific research platform, this study provides information on…
Species occurrence and distributional ecology of nearshore cetaceans in the Bay of Bengal, Bangladesh, with abundance estimates for Irrawaddy dolphins Orcaella brevirostris and finless porpoises Neophocaena phocaenoides
Smith, B. D.; Ahmed, B.; Mowgli, R. M.; Strindberg, S.
Journal of Cetacean Research and Management (2008)
A vessel-based line-transect survey conducted during February 2004 along 1,018km of systematic trackline in the nearshore waters of Bangladesh resulted in 111 ‘on-effort’ cetacean sightings including: Irrawaddy dolphins, Orcaella brevirostris…
