Gastrointestinal helminths of the cetaceans Cephalorhynchus eutropia and Phocoena spinipinnis accidentally entangled in gill-nets off the coast of Queule, Chile, were identified from 1989 to 1990. Pseudoterranova sp., Polymorphus (Polymorphus)…
Detailed post mortem examinations were carried out on 41 harbour porpoises (Phocoena phocoena) found dead on the coast of the United Kingdom. The commonest causes of death were entanglement in…
Since 1987, morbillivirus infections have caused serious disease outbreaks with high mortality among aquatic mammals. Baikal seals (Phoca sibirica) in Siberia were involved in an outbreak caused by a virus…
In 1988 and 1989, thousands of harbor seals (Phoca vitulina) died in the North Sea from phocine distemper infection. The morphology of thyroid glands from 40 harbor seals found dead…
In 1990, 74 dusky dolphins (Lagenorhynchus obscurus) and 10 Burmeister's porpoises (Phocoena spinipinnis) were examined for the presence of hyperpigmented marks and pinhole lesions on the skin (tattoo lesions) at…
Polychlorinated biphenyls (PCBs) suppress immunity, and may have exacerbated the effects of recent morbillivirus epizootics in harbour seals (Phoca vitulina) and striped dolphins (Stenella coeruleoalba). To test the hypothesis that…
Cetacean strandings have typically been classified into two types: 1) single strandings (including a mother/offspring pair); and 2) mass strandings. Singly stranded cetaceans have been reported world-wide wherever populations of…
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.…
Published and new fresh and museum specimens of Burmeister's porpoise, Phocoena spinipinnis, collected prior to the recent research in Peru, Chile and Argentina, are listed and described. Distribution is from…
Harbour porpoises are widely distributed in the seas around Denmark. Total abundance in Danish waters is estimated as approximately 100,000 animals. Population density varies considerably by area. There are probably…
