(...) The Dall porpoise, Phocoenoides dalli (True), occupies a rather restricted range in the northern Pacific. On the American side this extends from the Aleutian Islands to Santa Barbara Channel,…
As a rough measure of intelligence, brain weight: cord weight ratios in small delphinids compared favorably with, but were slightly less than , this ratio in man. Not all delphinids…
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…
To reduce incidental catch of cetaceans in gillnets, two forms of acoustic modifications are reviewed here; one to make gillnets more reflective to cetacean sonar, and another using active sound…
In July 1990, an observer program was established to collect data on the bycatch of the drift and set gillnet fisheries operating off the coast of California. These data are…
Many passive net fisheries exist along the Pacific coastlines of the USA (California, Oregon, Washington and Alaska), Canada (British Columbia) and the Russian Federation. Some incidental marine mammal mortality occurs…
In response to a request from the IWC Scientific Committee, this paper investigates the disagreement between two sets of Japanese statistics for the Dall's porpoise fishery, with particular reference to…
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…
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…
