Biological Conservation (2002)
Many salmon aquaculture sites in the Bay of Fundy employ acoustic harassment devices (AHDs) to deter seals from approaching fish pens. These devices may also exclude harbour porpoises (Phocoena phocoena)…
Surface and dive times of finless porpoises in Hong Kong’s coastal waters
Beasley, I.; Jefferson, T. A.;
The Raffles Bulletin of Zoology (2002)
We studied the surface and dive times of finless porpoises (Neophocaena phocaenoides) in Hong Kong from three land-based survey sites in winter/spring 2000, to allow the estimation of the trackline…
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.…
Characteristics of echolocation signals used by a harbour porpoise (Phocoena phocoena) in a target detection experiment
Teilmann, Jonas; Miller, Lee A.; Kirketerp, Tim; Kastelein, Ronald A.; Madsen, Peter T.; Nielsen, Bjarke K.; Au, Whitlow W. L.
Aquatic Mammals (2002)
The characteristics of echolocation signals used by a harbour porpoise (Phocoena phocoena) during a target detection experiment are described. A water-filled steel sphere (either 5.08 or 7.62 cm in diameter)…
Observations on marine mammals in southern Iran, January 2000
Keijl, Guido O.; van der Have, Tom M.
Zoology in the Middle East (2002)
Observations on the Finless Porpoise, Neophocaena phocaenoides, Humpback Dolphin, Sousa plumbea, and Dugong, Dugong dugon, in the Hara Protected Area, Khouran Straits, are presented. All are on the Red List…
Acoustic signals from free-ranging finless porpoises (Neophocaena phocaenoides) in the waters around Hong Kong
Goold, J. C.; Jefferson, T. A.
The Raffles Bulletin of Zoology (2002)
Acoustic signals from free-ranging finless porpoises were recorded in the waters around Hong Kong during March 2000. Finless porpoises produced short-duration high-frequency clicks. Signal analysis showed finless porpoise clicks to…
Inferring ecological separation from regional differences in radioactive caesium in harbour porpoises Phocoena phocoena
Tolley, KA; Heldal, HE
Marine Ecology Progress Series (2002)
Geographic variation in the level of radioactive caesium-137 (137Cs) was examined from the axial muscle of 36 harbour porpoises Phocoena phocoena obtained as bycatch from 5 locations along the coast…
Preliminary analysis of geographic variation in cranial morphometrics of the finless porpoise (Neophocaena phocaenoides)
Jefferson, T. A.
The Raffles Bulletin of Zoology (2002)
The taxonomy of the finless porpoise (Neophocaena phocaenoides), while better-studied than that of many species of small cetaceans, still suffers from some uncertainties and a general lack of data from…
Multiple insights into the reproductive function of harbour porpoises (Phocoena phocoena): An ongoing study
Desportes, Geneviève; Kristensen, Jakob H; Benham, Deborah; Wilson, Sandie; Jepsen, Trine; Korsgaard, Bodil; Siebert, Ursula; Driver, Jörg; Amundin, Mats; Hansen, Kirstin; Shephard, Gwyneth
NAMMCOSP (2003)
The harbour porpoises kept at the Fjord & Bælt since April 1997 offer a unique opportunity to gain a better understanding of the reproductive function in harbour porpoises, especially in…
Bycatch as a potential threat to harbour porpoises (Phocoena phocoena) in Polish Baltic waters
Skóra, Krzysztof E; Kuklik, Iwona
NAMMCOSP (2003)
Sixty-two verified reports obtained in the years 1990-1999 on the bycatch, strandings and sightings of harbour porpoises in the Polish Baltic were analysed in this study. In relative terms the…
