Aquatic Mammals (1994)
Epidermal thickness and relative papillary height of the skin from the urogenital region were compared with values from the ventral aspect of the flipper and the mid-dorsal body wall. Data…
The potential for reducing entanglement of dolphins and porpoises with acoustic modifications to gillnets
Dawson, S. M.
Report of the International Whaling Commission (1994)
To reduce incidental catch of cetaceans in gillnets, two forms of acoustic modifications are reviewed here; one to make gillnets more reflective to cetacean sonar, and another using active sound…
Harbor porpoise interactions with a chinook salmon set-net fishery in Washington State
Gearin, P. J.; Melin, S. R.; DeLong, R. L.; Kajimura, H.; Johnson, M. A.
Report of the International Whaling Commission (1994)
A cooperative study based on an agreement between the National Marine Fisheries Service and the Makah Indian Tribe was conducted during 1988-90 to assess the nature and magnitude of harbor…
Swimming kinematics of a harbor porpoise (Phocoena phocoena) and an Atlantic white-sided dolphin (Lagenorhynchus acutus)
Curren, Kristina; Lien, John
Marine Mammal Sci (1994)
(...) Little data exists on the swimming movements of dolphins and whales. The earliest record of cetacean swimming kinematics came from Parry (1949), who observed the swimming motions of a…
The effect of increasing observer trackline effort in shipboard line transect surveys for harbor porpoise
Polacheck, T.
Report of the International Whaling Commission (1995)
Previous double team experiments testing line transect methodology for harbor porpoise indicated that a relatively small proportion of the sightings were actually seen by both teams. Results of an additional…
The relationship between heart mass and body mass for three cetacean genera: Narrow allometry demonstrates interspecific differences
Ridgway, Sam H.; Kohin, Suzanne
Marine Mammal Sci (1995)
(...) Brody (1945) fitted an allometric equation to heart mass (kg) as a function of body mass (kg) for adult mammals ranging in body size from 0.01 to over 100,000…
Study of the cranial sinus nematode, Stenurus minor (Metastrongyloidea), in the harbour porpoise, Phocoena phocoena
Faulkner, J.
Master's Thesis - McGill University (1995)
Seventy-eight harbour porpoises, Phocoena phocoena, (33 females, 45 males) were obtained from the summer (June-September) cod fishery incidental-by-catch in the Gulf of St. Lawrence, and examined for the presence of…
Levels of organochlorine compounds, including PCDDS and PCDFS, in the blubber of cetaceans from the west coast of North America
Jarman, W. M.; Norstrom, R. J.; Muir, D. C. G.; Rosenberg, B.; Simon, M.; Baird, R. W.
Marine Pollution Bulletin (1996)
Levels of organochlorine compounds (PCDD, PCDF, PCB and organochlorine pesticides) were determined in cetaceans collected from the west coast of North America between 1986 and 1989. The samples included gray…
Functional morphology and homology in the odontocete nasal complex: Implications for sound generation
Cranford, T. W.; Amundin, M.; Norris, K. S.
Journal of Morphology (1996)
The site and physiologic mechanism(s) responsible for the generation of odontocete biosonar signals have eluded investigators for decades. To address these issues we subjected postmortem toothed whale heads to interrogation…
Investigations on cetacean sonar XI: Intrinsic comparison of the wave shapes of some members of the Phocoenidae family
Kamminga, C.; Cohen Stuart, A.; Silber, G. K.
Aquatic Mammals (1996)
A comparison of the acoustic waveforms of three different species, Phocoena phocoena, Phocoena sinus and Neophocaena phocaenoides of the sub-family Phocoeninae is made with the species Phocoenoides dalli of the…
