Report of the International Whaling Commission (1995)
Dall's porpoise in the western North Pacific Ocean suffered incidental mortality from the gillnets of the Japanese high seas salmon fishery until 1987 and mortality from the high seas squid…
Trends in abundance of Dall’s porpoise in the western north Pacific, 1979 to 1989
Turnock, B.J.; Buckland, S.T.
Report of the International Whaling Commission (1995)
Two density indices of Dall's porpoise abundance were estimated for the western North Pacific from 1979 to 1989. One index is the density of animals (number of animals per square…
Report of the harbour porpoise age determination workshop, Oslo, 21-23 May 1990
Bjorge, A.; Hohn, A.A.; Kvam, T.; Lockyer, C.; Schweder, T.; Aarefjord, H.
Report of the International Whaling Commission (1995)
A workshop on age determination in harbour porpoises (Phocoena phocoena) was held in Oslo, Norway, 21-23 May 1990. During the workshop, the principles of formation of dental layers were reviewed,…
A review of factors involved in zonation in Odontocete teeth, and an investigation of the likely impact of environmental factors and major life events on harbour porpoise tooth structure
Lockyer, C.
Report of the International Whaling Commission (1995)
Variation in zonation and Growth Layer Group (GLG) formation and underlying causes are reviewed. Five different types of anomaly were investigated in the teeth of harbour porpoise (Phocoena phocoena): pulp…
Procedures and techniques applied by NINA for cutting, staining, mounting and ageing porpoise teeth
Kvam, T.
Report of the International Whaling Commission (1995)
Age determination of terrestrial mammals based on growth layers in the teeth has been a routine technique at NINA in Trondheim for many years. This paper describes how this well…
Reproduction in the porpoises (Phocoenidae): Implications for management
GASKIN, D. E.; SMITH, G. J. D.; WATSON, A. P.; YASUI, W. Y.; YURICK, D. B.
Report of the International Whaling Commission (1984)
The population biology of most phocoenid species is still rather poorly understood. It is important that we improve our knowledge in view of concerns which have been expressed in recent…
Developmental patterns in osteology and external morphology in Phocoena phocoena
Stuart, L.J.; Morejohn, G.V.
Report of the International Whaling Commission (1980)
Dentinal growth layer groups (GLGs) in teeth were counted for 84 beach-cast specimens of Phocoena phocoena from the northeastern Pacific (mostly California). Measurements of external, cranial, and postcranial traits were…
Observations on distribution and intraspecific variation in pigmentation patterns of Odontocete Cetacea in the western North Atlantic
Mercer, M. C.
J. Fish. Res. Bd. Can. (1973)
This paper comprises sight records for nine species and morphometries, color descriptions, and miscellaneous notes on the food and parasites of seven species of small odontocetes observed from West Greenland…
Severe progressive meningoencephalitis due to Cryptococcus sp. in a live-stranded harbor porpoise (Phocoena phocoena) undergoing rehabilitation
Haulena, M.; Himsworth, C.; Anderson, C.; Akhurst, L.; Ivančić, M.; Malpas, D.A.; Pollock, J.S.; Raverty, S.
Conference of the International Association for Aquatic Animal Medicine (2012)
Cryptococcus gatti is an important infectious disease in the northeastern Pacific. The condition has been associated with significant mortality in harbor porpoise (Phocoena phocoena), Dall’s porpoise (Phocoenoides dalli) and Pacific…
Gas bubble disease in harbor porpoises (Phocoena phocoena) stranded in British Columbia
Raverty, Stephen A.; Spavin, Lisa; Cottrell, Paul; Ford, John; Hall, Anna; Gaydos, Joe; Haulena, Martin; Ivančić, Marina
Conference of the International Association for Aquatic Animal Medicine (2010)
Harbour porpoises (Phocoena phocoena) are among the most abundant small cetaceans in the northeastern Pacific and there is a distinct bimodal seasonal stranding trend. Increased numbers of animals present in…
