Report of the International Whaling Commission (1996)
This paper summarises current knowledge of the three populations of harbour porpoises in US and Canadian Atlantic waters. During the summer, the populations are centred in the Gulf of Maine/Bay…

Borrell, Asunción; Aguilar, Alex; Cantos, Gemma; Lockyer, Christina; Heide-Jørgensen, Mads Peter; Jensen, Jette
Environmental Pollution (2004)
During the 1995 hunting season, 75 harbour porpoises (Phocoena phocoena) were sampled in three locations in West Greenland: Maniitsoq, Nuuk, and Paamiut. Sex, age, morphometrics, reproductive condition, and organochlorine compound…
Maternal care, calf training and site fidelity in a wild harbour porpoise in the North Sea
Camphuysen, Kees C. J.; Krop, Anton
Lutra (2011)
(...) Direct, undisturbed observations of interactions of mother and offspring in harbour porpoises (Phocoena phocoena) in the wild are extremely rare. Because harbour porpoises are seldom held and hardly breed…
Reproduction and reproductive seasonality in Danish harbour porpoises, Phocoena phocoena
Sørensen, Thomas Buus; Kinze, Carl Christian
Ophelia (1994)
The reproduction and reproductive seasonality of 365 Danish harbour porpoises (Phocoena phocoena (L.)) incidentally caught in various gill nets or stranded, was studied. The animals were collected from all Danish…
The ontogeny of echolocation in a Yangtze finless porpoise (Neophocaena phocaenoides asiaeorientalis)
Li, Songhai; Wang, Ding; Wang, Kexiong; Xiao, Jianqiang; Akamatsu, Tomonari
The Journal of the Acoustical Society of America (2007)
Acoustic and concurrent behavioral data from one neonatal male Yangtze finless porpoise (Neophocaena phocaenoides asiaeorientalis) in captivity were presented. The calf click train was first recorded at 22 days postnatal,…
Age and reproduction of the finless porpoises, Neophocaena asiaeorientalis , in the Yellow Sea, Korea
Lee, Young Ran; An, Yong Rock; Park, Kyum Joon; Sohn, Hawsun; An, Du Hae; Kim, Su Am
Animal Cells and Systems (2013)
A total of 116 finless porpoises, Neophocaena asiaeorientalis, were collected in the Yellow Sea off Korea. About 111 specimens were incidentally caught by stow nets on anchors from March to…
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…
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…
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…
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…
