In March 1988 three Harbour porpoises (Phocoena phocoena) were stranded on the Dutch coast and sent to the Harderwijk Marine Mammal Park for rehabilitation. The following parameters were recorded during…
Information on the movement of cetaceans in relation to survey vessels is important for determining if abundance and density estimates from ship-based line transect sighting surveys are biased. A ship-based…
Stenurus australis n. sp. (Nematoda: Pseudaliidae) found in the nasal and cranial sinuses of Phocoena spinipinnis (Burmeister, 1865) is described. The hosts were obtained at the Chimbote, Ancash (09°04'S-78°35'W) and…
We estimated the potential intrinsic rate of increase (r) of the harbour porpoise (Phocoena phocoena) population in the Bay of Fundy and Gulf of Maine using empirical data on reproductive…
A study of Dall's porpoise distribution and behaviour between September 1986 and February 1989 confirmed the year-round presence of these animals in Monterey Bay, California. Dall's porpoises in the Bay…
This paper reports the population status of the endangered Chinese River dolphin - Lipotes vexillifer, the factors causing the population decline of Lipotes and protective measures adopted in recent years,…
This report describes the first sounds recorded from the phocoenid porpoise, vaquita, (Phocoena sinus, Norris & McFarland, 1958). High-frequency recordings were obtained near free-ranging vaquita in the northern Gulf of…
Total Hg levels were determined in 17 harbour porpoises Phocoena phocoena collected in the North Sea and the Kattegat (muscle, liver and kidney), as well as in a sperm whale…
(...) The finless porpoise (Neophocaena phocaenoides) shows a decidedly inshore distribution pattern (Kasuya and Kureha 1979), occurring in coastal waters frequented by fishermen. Its lack of a beak and a…
