Dentinal growth layer groups (GLGs) in teeth were counted for 84 beach-cast specimens of Phocoena phocoena from the northeastern Pacific (mostly California). Measurements of external, cranial, and postcranial traits were…
This paper comprises sight records for nine species and morphometries, color descriptions, and miscellaneous notes on the food and parasites of seven species of small odontocetes observed from West Greenland…
Cryptococcus gatti is an important infectious disease in the northeastern Pacific. The condition has been associated with significant mortality in harbor porpoise (Phocoena phocoena), Dall’s porpoise (Phocoenoides dalli) and Pacific…
Harbour porpoises (Phocoena phocoena) are among the most abundant small cetaceans in the northeastern Pacific and there is a distinct bimodal seasonal stranding trend. Increased numbers of animals present in…
The distribution of harbour porpoises Phocoena phocoena in southern Europe and along the Atlantic African coast is poorly understood, with tentative assessments suggesting a discrete West African population with a…
Estimating the abundance of cetaceans from aerial survey data requires careful attention to survey design and analysis. Once an aerial observer perceives a marine mammal or group of marine mammals,…
(...) On 11 September 1997, a harbour porpoise was found dead on a beach near Pictou, Nova Scotia, Canada (45° 41′N, 62° 42′W), bordering Northumberland Strait in the Gulf of…
This is the first study estimating cetacean by-catch in the Turkish western Black Sea turbot fishery. One turbot fishing boat was observed during two fishing seasons, from April through July…
Marine mammal stock assessments provide information that is valuable to public sector management and the private fishing sector; however, data are costly to collect. The precautionary approach, which is widely…
A global review of mortality of porpoises in gillnet fisheries indicates that individuals of all six species become entangled and die in gillnets. Harbor porpoises Phocoena phocoena are taken throughout…
