(...) Order Cetacea, Suborder Odontoceti, Family Phocoenidae. The family contains four extant genera: Phocoena, Australophocaena, Neophocaena, and Phocoenoides (Barnes, 1985). Barnes (1984, 1985) has proposed two subfamilies within the Phocoenidae.…
Large amounts of legacy unexploded ordnance (UXO) are still present in the North Sea. UXO are frequently accidentally encountered by fishermen and dredging vessels. Out of concern for human safety…
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)…
Organochlorine contaminants, including polychlorinated biphenyls (PCBs), chlorinated bornanes (CHBs), dichloro-diphenyl-trichloroethanes (DDTs), chlordanes (CHLORs), hexachlorocyclohexanes (HCHs) and, chlorobenzenes (CBZs) were quantified in 188 harbour porpoises (Phocoena phocoena) killed in commercial fisheries…
A 60-cm female fetus recovered from a Dall's porpoise (Phocoenoides dalli) found dead in southern British Columbia was fathered by a harbour porpoise (Phocoena phocoena). This is the first report…
This report presents results of field trials of the POD, carried out in Pembrokeshire, UK, from August to December 1998. The POD is an acoustic data logger, designed to operate…
Eight fresh specimens of Burmeister's porpoise caught in gillnets in the Necochea area (Buenos Aires Province) were studied for external morphometrics, age, basic reproductive data, organochlorine pollutant levels and parasites.…
Harbour porpoises (Phocoena phocoena) are notoriously difficult to observe and become very difficult to see in moderate or rough sea conditions. Passive acoustic monitoring provides a complementary study method to…
The northernmost records of four cold-water cetacean species in the southwestern Atlantic are presented: the spectacled porpoise (Phocoena dioptrica), Layard's beaked whale (Mesoplodon layardii), Commerson's dolphin (Cephalorhynchus commersonii), and Peale's…
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…
