Marine Mammal Sci (2001)
Prevalence of the larval cestode, Phyllobothrium delphini, was estimated from 2,445 Dall's porpoise, Phocoenoides dalli, from the incidental take of the Japanese high seas salmon drift-net fishery in the northwestern…
Trends in the maternal investment of harbour porpoises are uncoupled from the dynamics of their primary prey
Read, A. J.
Proceedings of the Royal Society B: Biological Sciences (2001)
Harbour porpoises in the Bay of Fundy and Gulf of Maine feed primarily on Atlantic herring. Herring stocks have undergone dramatic fluctuations in abundance over the past three decades due…

The enigma of harbor porpoise presence in the Mediterranean Sea
Frantzis, Alexandros; Gordon, Jonathan; Hassidis, Gilda; Komnenou, Anastasia
Marine Mammal Sci (2001)
(...) Harbor porpoises are assumed to have colonized the Black Sea from the Atlantic Ocean (Gaskin 1982, Rosel 1997). This hypothesized relationship is based on both geographical proximity and genetic…
First records of the spectacled porpoise Phocoena dioptrica in continental Australian waters
Evans, Karen; Kemper, Catherine; Hill, Mark
Marine Mammal Sci (2001)
(...) The spectacled porpoise, Phocoena dioptrica (Lahille, 1912), is a little-known species found in cool temperate, sub- and low-antarctic waters of the Southern Hemisphere (Jefferson et al. 1993, Goodall and…
Reactions of harbor porpoises Phocoena phocoena and herring Clupea harengus to acoustic alarms
Culik, B.M.; Koschinski, S.; Tregenza, N.; Ellis, G.M.
Marine Ecology Progress Series (2001)
Small cetaceans are susceptible to incidental mortality in the various forms of gillnet fisheries throughout their range. Research conducted since 1994 has shown that acoustic alarms (pingers) emitting high-frequency pulsed…
Post-mortem findings in harbour porpoises (Phocoena phocoena) from the German North and Baltic Seas
Siebert, U.; Wünschmann, A.; Weiss, R.; Frank, H.; Benke, H.; Frese, K.
Journal of Comparative Pathology (2001)
Between 1991 and 1996, necropsies were performed on 445 harbour porpoises (Phocoena phocoena), in various states of preservation, stranded on German coasts or accidentally caught by German fishermen. The animals…
Oxygen consumption and swim speed of the harbor porpoise Phocoena phocoena
Otani, Seiji; Naito, Yasuhiko; Kato, Akiko; Kawamura, Akito
Fisheries Science (2001)
The rate of oxygen consumption and energetic cost of locomotion of captive harbor porpoises Phocoena phocoena were studied in Hokkaido, Japan, using respirometry together with externally attached devices (a data…
Abundance decline in the finless porpoise population in the Inland Sea of Japan
Kasuya, T.; Yamamoto, Y.; Iwatsuki, T.
The Raffles Bulletin of Zoology (2002)
From 5 March to 1 July, 1999 and 2000, we made six shipboard surveys for finless porpoises (Neophocaena phocaenoides) in the Inland Sea, which is believed to be inhabited by…
Geographical variation in harbour porpoise (Phocoena phocoena) skulls: Support for a separate non-migratory population in the Baltic proper
Huggenberger, S.; Benke, H.; Kinze, C.C.
Ophelia (2002)
We measured metric and scored non-metric characters of 242 harbour porpoise (Phocoena phocoena) skulls from the North and the Baltic Sea and subdivided them into three geographical areas: The German…
