Aquatic Mammals (2008)
Most of the data collected on the reproduction of harbour porpoises (Phocoena phocoena) comes from by-caught or stranded animals and is therefore opportunistic in nature. Harbour porpoises kept in a…

Growth and reproduction of three populations of finless porpoise, Neophocaena phocaenoides, in Chinese waters
Gao, Anli; Zhou, Kaiya
Aquatic Mammals (1993)
We have 189 specimens available for this work. One-hundred and sixty-seven specimens from the Yangtze, Yellow Sea and South China Sea populations were aged and used in studying the growth…
Reproduction and reproductive organs in Neophocaena asiaeorientalis from the Yangtse River
Chen, P-X.; Renjun, L.; Harrison, J.
Aquatic Mammals (1982)
Two species of freshwater dolphin are known to have existed in the Yangtse River, China, for over two thousand years. One is a white form, the Baiji (Lipotes vexllifer), the…
Growth and reproduction of the finless porpoise in southern China
Jefferson, T. A.; Robertson, K. M.; Wang, J. Y.
The Raffles Bulletin of Zoology (2002)
We studied the growth and reproduction of finless porpoises in southern China, based on 86 specimens collected as strandings or fisheries bycatches in Hong Kong, southern Fujian Province, and Taiwan.…
Harbour porpoises (Phocoena phocoena) in the North Atlantic: Biological parameters
Lockyer, Christina
NAMMCOSP (2003)
Biological parameters for harbour porpoises are reviewed throughout their range in the North Atlantic. Most information is based on studies of a combination of directed catches, bycatches and strandings. All…
Foraging behaviour and reproductive season habitat selection of northeast Pacific porpoises
Hall, A.
Doctoral Thesis - University of British Columbia (2011)
Behavioural observations are fundamental to understanding and defining the habitat needs of animals. I compiled the behavioural repertoires reported for harbour (Phocoena phocoena) and Dall’s porpoise (Phocoenoides dalli) by classifying…
Life history of the vaquita, Phocoena sinus (Phocoenidae, Cetacea)
Hohn, A. A.; Read, A. J.; Fernandez, S.; Vidal, O.; Findley, L. T.
Journal of Zoology (1996)
The vaquita, Phocoena sinus, is the most endangered marine cetacean primarily due to incidental mortality in fishing nets. We examined a sample of 56 vaquitas to study the life history…
Subcellular distribution of trace elements in kidney of a mother–fetus pair of Dall’s porpoises (Phocoenoides dalli)
Yang, Jian; Kunito, Takashi; Anan, Yasumi; Tanabe, Shinsuke; Miyazaki, Nobuyuki
Chemosphere (2008)
Total and subcellular renal Zn, Cu, Se, Mn, V, Hg, Cd and Ag were determined by a mother–fetus pair of Dall’s porpoises (Phocoenoides dalli). All element concentrations in the maternal…
Natural hybridization between Dall’s porpoises (Phocoenoides dalli) and harbour porpoises (Phocoena phocoena)
Willis, Pamela M; Crespi, Bernard J; Dill, Lawrence M; Baird, Robin W; Hanson, M Bradley
Can. J. Zool. (2004)
Natural hybridization occurs rarely in mammals compared with other taxonomic groups of animals. Cetaceans appear unique among mammals in exhibiting striking karyological uniformity, which suggests that they have the potential…
