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…

Line transect analysis was applied to the 1987-1990 North Pacific marine mammal sightings survey data, with a regression adjustment for size-biased sampling of schools. Abundance of Pacific white-sided dolphins is…
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…
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…
(...) Little data exists on the swimming movements of dolphins and whales. The earliest record of cetacean swimming kinematics came from Parry (1949), who observed the swimming motions of a…
A total of 139 types of passive fishing gear are used in Chinese marine fisheries. Finless porpoises, false killer whales, bottlenose dolphins and common dolphins are known to be caught…
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…
Incidental catches of harbour porpoise by commercial fisheries in the Estuary and Gulf of St. Lawrence, Canada were examined. Two questionnaires, one in 1989 and one in 1990, were sent…
Considerable numbers of cetaceans are killed incidentally every year during fishing operations on the Portuguese coast. Although a small number of marine mammals are caught by trawlers and fishing traps,…
The Japanese squid driftnet fishery began in 1978 in the northwestern Pacific, targeting the flying squid, Ommastrephes bartrami, and was effectively closed in 1992. In response to the rapid growth…
