Biological data on the harbour porpoise in Portuguese coastal waters are scarce, mainly because of the small number of animals available for study. Nevertheless, a regular geographical distribution pattern can…
Information on the movement of cetaceans in relation to survey vessels is important for determining if abundance and density estimates from ship-based line transect sighting surveys are biased. A ship-based…
Harbor porpoises (Phocoena phocoena) have been killed in gillnets set for halibut in central California since at least 1969. In the Monterey Bay area (Pigeon Pt. to Pt. Sur), past…
In 1988 and 1989 we monitored the fish terminal of Pucusana, central Peru, for 259 and 233 days respectively, and observed 1,613 and 1,292 small cetaceans landed. The estimated total…
Between 1982 and 1993, 55 coastal locations throughout Mexico were visited to investigate mortality of small cetaceans. A total of 139 records concerning the use of small cetaceans by fishermen…
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…
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…
Coastal and pelagic fishing activities in the area of Necochea harbour, where high mortality of franciscanas (Pontoporia blainvillei) in gillnets had been previously reported, and at Claromeco, a small gillnet…
This paper reviews published and unpublished information on the mortality of cetaceans in gillnets in Mexico, Central America and the wider Caribbean. Data on this incidental mortality are provided from…
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…
