The geographical variation of the colour types of the species indicates three local stocks in the northwestern North Pacific and western Bering Sea (WNP/BS), off the Pacific coast of Japan…

Dall’s porpoise, Phocoenoides dalli (True), is commonly encountered over the continental shelf of North America and in offshore and pelagic waters of the western and eastern North Pacific Ocean. This…
The distribution of the harbour porpoise Phocoena phocoena (L.). is re-examined using a compilation of all available recent information. Three isolated major populations of this species exist: in the North…
Some growth parameters of the western North Pacific dalli-type Dall's porpoise were estimated from 167 specimens taken with hand-held harpoons on two cruises and compared with data obtained previously from…
Eighty nine mother-calf Dall's porpoise pairs were sighted in August and September 1982, 1983 and 1985 in the Bering Sea and the western North Pacific (outside the principal range of…
Dall's porpoises from the Sea of Japan population taken by a dolphin fishery vessel were examined. Estimated body lengths at sexual maturity were similar to those for the truei-type population…
The morphology of diatoms which consistently occur in circular to oval colonies on the skin of North Pacific Dall's porpoise was examined. Two previously described cetacean diatoms Stauroneis aleutica Nemoto…
Dolphins of several species are killed incidentally in driftnet fisheries on the high seas in the North Pacific. Information on stock identity, necessary for assessment and management of the dolphin…
At the meeting of the IWC Scientific Committee held in Dublin in May 1995, the special topic addressed by the sub-committee on small cetaceans was the North Atlantic harbour porpoise.…
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…
