A line-transect survey for the critically endangered vaquita, Phocoena sinus, was carried out in October–November 2008, in the northern Gulf of California, Mexico. Areas with deeper water were sampled visually…
Information on the harbour porpoise in Polish waters is reviewed and a corrected and updated list of catches, strandings and sightings given. The number of records per year has changed…
The abundance of the only population of vaquitas, Gulf of California harbor porpoise (Phocoena sinus), is estimated from four surveys conducted in Mexico between 1986 and 1993, using a variety…
The status of harbour porpoise (Phocoena phocoena) populations in the North Atlantic has raised numerous concerns. Although a number of factors that may be adversely affecting harbour porpoise populations have…

Harbour porpoise (Phocoena phocoena) in California are subject to incidental mortality in gillnet fisheries. The status of this population is uncertain. We review information on population structure and conclude that…
Two density indices of Dall's porpoise abundance were estimated for the western North Pacific from 1979 to 1989. One index is the density of animals (number of animals per square…
Species Information The harbour porpoise is one of the smallest cetacean species, born at 80-90 cm and only occasionally reaching lengths of close to 2 m. In general, harbour porpoises…
