Interactions between marine mammals and fisheries were monitored along the southwestern Atlantic coast of Argentina from Bahia Samborombon (Buenos Aires Province) to Tierra del Fuego Island. A variety of fisheries…
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…
The rate of occurrence of click trains of two harbor porpoises (Phocoena phocoena) were counted during 14 nights. We developed an echolocation signal detection system that was harnessed to a…
Small cetaceans and some great whales become entangled and die in gillnets in a variety of fisheries in the northeastern Indtan Ocean. Information on operational details, present status and future…
Cetacean strandings have typically been classified into two types: 1) single strandings (including a mother/offspring pair); and 2) mass strandings. Singly stranded cetaceans have been reported world-wide wherever populations of…
Since 1974, species of small cetaceans, fur seals, sea lions, sea birds and to some extent sea otters, have been taken deliberately each year for bait in the Chilean artisanal…
(...) 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…
Gillnet and trap fisheries of the Northwest Atlantic and their potential for cetacean entanglement are reviewed. Ten major categories of passive fisheries are identified, five of which are known to…
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…
The refractive index of the cornea of a harbor porpoise eye was measured by two-wavelengths laser-interferometry. In the thickest part of the cornea a refractive index of about 1.53 was…
