The purpose of the present study was to investigate the level of persistent chlorinated hydrocarbons and heavy metals in different tissues of four harbour porpoises caught at Danish coasts and…
Two harbour porpoises, a male and a female, both around 10 months old, which had to be left alone for periods between bio-acoustical investigations, developed stereotyped motor patterns and signs…
The harbour porpoise and all other cetaceans are totally protected in Danish waters, but not in the waters around Greenland and the Faroe Islands. This means that it is forbidden…
The rearing of unweaned dolphins has hitherto not been described in literature. In 1973 our laboratory received 2 juvenile harbour porpoises (Phocoena phocoena) and we succeeded in rearing them on…
In this paper we report findings on the diet of the harbour porpoise (Phocoena phocoena) in Danish, Swedish and Norwegian waters. The study is based on stomach contents from 247…
Harbour porpoises (Phocoena phocoena) stranding in large numbers around the southern North Sea with fatal, sharp-edged mutilations have spurred controversy among scientists, the fishing industry and conservationists, whose views about…
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…
