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…


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…


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…


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…


Ultrastructure of enamel and dentine in extant dolphins (Cetacea: Delphinoidea and Inioidea)

Loch, Carolina; Duncan, Warwick; Simões-Lopes, Paulo C.; Kieser, Jules A.; Fordyce, R. Ewan
Zoomorphology (2012)

Longitudinal and cross sections of teeth from 17 species of the Recent dolphins (Delphinoidea and Inioidea) were examined under scanning electron microscope to study the arrangement and ultrastructure of dental…


Isotopic assessment of prey and habitat preferences of a cetacean community in the southwestern South Atlantic Ocean

Riccialdelli, L.; Newsome, S. D.; Fogel, M. L.; Goodall, R. N. P.
Marine Ecology Progress Series (2010)

We used stable carbon (δ13 C) and nitrogen (δ15 N) isotope analysis to investigate the trophic ecology of 8 small cetacean species of the southwestern South Atlantic Ocean: 6 delphinids…


Reversible bending of the dorsal fins of harbor porpoises (Phocoena phocoena) and a striped dolphin (Stenella coeruleoalba) in captivity

Kastelein, Ronald A.; Triesscheijn, Rob J. V.; Jennings, Nancy
Aquatic Mammals (2016)

The dorsal fin of odontocetes has, among other roles, hydrodynamic and thermoregulatory functions. In captivity, the dorsal fin sometimes bends laterally. Bending of the dorsal fin was described in 13…
