True porpoises are a morphologically distinctive and evolutionarily old group of odontocete cetaceans classified as the family Phocoenidae. They are distinct from members of the family Delphinidae, with which they…
Serial sections of 13 embryos and fetuses of the harbor porpoise from 10 mm crown-rump length up to 167 mm total length were studied. Unlike the adult animals, ontogenetic stages…
(...) Although various sensory mechanisms are present in cetaceans, special navigational problems occur when animals are in a pelagic environment which can minimize available cues. Dawbin (1966) has observed that…
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…
The distribution, movements, and relative population abundance of harbor porpoises were studied in the Fish Harbour region of New Brunswick, Canada (lat. 44°59'30"-45°01'00"N, long. 66°54'00"-66°57'00"W), from 1970 to 1978. In…
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…
Since 1978, the annual incidental take of Dall's porpoises by the Japanese salmon land-based and mothership fisheries has been reported to the International North Pacific Fisheries Commission by the Japan…
To improve knowledge of the life history of Dall's porpoise, Phocoenoides dalli (True, 1885) that are incidentally caught by the Japanese salmon mothership fishery in the northwestern North Pacific, a…
During 349 hours of sighting surveys conducted from late June to early August 1979 in the northwestern North Pacific Ocean and the southern Bering Sea, 167 schools of Phocoenoides dalli…
