This paper summarises current knowledge of the three populations of harbour porpoises in US and Canadian Atlantic waters. During the summer, the populations are centred in the Gulf of Maine/Bay…
The vaquita, Phocoena sinus, is the most endangered marine cetacean primarily due to incidental mortality in fishing nets. We examined a sample of 56 vaquitas to study the life history…
We used 11 restriction endonucleases to study mtDNA variation in 101 Dall's porpoises Phocoenoides dalli from the Bering Sea and western North Pacific. There was little phylogeographic patterning among the…
The movements of nine harbour porpoises, Phocoena phocoena (L.), in the Bay of Fundy and Gulf of Maine were tracked using satellite telemetry. Transmitters were attached to the porpoises in…
This report provides harbor porpoise bycatch estimates for 1994 and 1995. The analysis required adjusting for changes in data collection methods that went into effect in June 1994, in which…
The most serious danger to dolphins and porpoises around the world is the threat from various forms of gill-net fishing. One potential way to reduce the number of deaths of…
A programme to assess the cetacean by-catch in the Irish and UK set gillnet fisheries in the Celtic Sea was conducted from August 1992 to March 1994 using volunteer observers.…
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…
Bycatch of harbour porpoises (Phocoena phocoena) occurs in most gillnet fisheries throughout the continental shelf area in the Northern Hemisphere. A few behavioural studies have attempted to ascertain the detection…
