Aquatic Mammals (1974)
The rearing of unweaned dolphins has hitherto not been described in literature. In 1973 our laboratory received 2 juvenile harbour porpoises (Phocoena phocoena) and we succeeded in rearing them on…

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…
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…
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…
The population biology of most phocoenid species is still rather poorly understood. It is important that we improve our knowledge in view of concerns which have been expressed in recent…
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…
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…
The early postnatal growth of bottlenose dolphins and finless porpoises was studied using 97 body length records of 61 individuals born in aquariums. The growth rates observed were similar to…
The vaquita (Phocoena sinus) is a small porpoise found only in the northern Gulf of California. This species may have been subject to high levels of mortality in the gill-net…
