Dall's porpoises, Phocoenoides dalli, were often incidentally caught in the Japanese salmon gillnet fishery in the North Pacific. In order to investigate the reasons for entanglement, their auditory characteristics and…
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…
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…
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…
(...) 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…
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…
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…
This paper reviews and summarises published and unpublished information on harbour porpoises in Irish waters and presents results of recent research. Harbour porpoises have been recorded from all Irish coasts…
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…
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…
