Journal of Applied Ecology (2002)
The status of small cetaceans in the North Sea and adjacent waters has been of concern for many years. Shipboard and aerial line transect surveys were conducted to provide accurate…
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…
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…
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…
Distribution and abundance of finless porpoises in Hong Kong and adjacent waters of China
Jefferson, T. A.; Hung, S. K.; Law, L.; Torey, M.; Tregenza, N.
The Raffles Bulletin of Zoology (2002)
We studied the distribution and abundance of finless porpoises (Neophocaena phocaenoides) in Hong Kong and adjacent waters of China's Guangdong Province between September 1995 and November 2000. Vessel (50,194 km)…
Harbour porpoise interactions with the 2001 selective salmon fisheries in southern British Columbia and license holder reported small cetacean by-catch
Hall, A.; Ellis, G.; Trites, A.W.
Selective Salmon Fisheries Science Program Report (2002)
We estimated the incidental mortality of harbour porpoise (Phocoena phocoena) in selective salmon fisheries in southern British Columbia from reports received from federal fisheries observers (2001) and license holders (1997…
