Total Hg levels were determined in 17 harbour porpoises Phocoena phocoena collected in the North Sea and the Kattegat (muscle, liver and kidney), as well as in a sperm whale…

Of the 79 recent species of cetaceans 51 have been examined relative to the osteology of the flipper and the scapula and, in addition to this, video-recordings of 13 different…
We present the results of an aerial line transect census of cetaceans along the California coast during March and April 1991. This survey was the first of two aerial surveys…
We studied development and sexual dimorphism in external measurements of Dall's porpoises (Phocoenoides dalli) from the northwestern North Pacific. Relative rates of increase in the measurements of the head and…
Information on small cetacean mortality in Peruvian fisheries is reviewed for the 1990-1993 period, i.e. after the national ban on cetacean exploitation. Most ports along the Peruvian coast were sampled…
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…
Dall's porpoises, Phocoenoides dalli, were often incidentally caught in the Japanese salmon gillnet fishery in the North Pacific. In order to investigate the reasons for entanglement, their auditory characteristics and…
Data are reported on marine mammal mortality collected from California's gillnet fisheries for California halibut and Pacific angel shark (set net) and swordfish and pelagic sharks (driftnet) during the first…
Strandings and sightings data of toothed whales entangled in fishing gear are documented for the Southern California Bight from 1975-90. Entanglements involve three fisheries: a nearshore set gillnet fishery; an…
Epidermal thickness and relative papillary height of the skin from the urogenital region were compared with values from the ventral aspect of the flipper and the mid-dorsal body wall. Data…
