Report of the International Whaling Commission (1994)
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…
Report of the International Whaling Commission (1994)
This paper reviews published and unpublished information on the mortality of cetaceans in gillnets in Mexico, Central America and the wider Caribbean.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…
Report of the International Whaling Commission (1994)
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…
Report of the International Whaling Commission (1994)
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…
Report of the International Whaling Commission (1994)
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…
Report of the International Whaling Commission (1994)
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…

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…
Report of the International Whaling Commission (1994)
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…
Report of the International Whaling Commission (1994)
The harbour porpoise (Phocoena phocoena) is the only cetacean incidentally caught in significant numbers by the Danish fishing fleet and there is some concern that the populations in Danish waters…
Report of the International Whaling Commission (1994)
Thousands of porpoises die annually in monofilament gillnets. Simple net modifications may alleviate the problem. In June through August 1988, we quantified harbour porpoise (Phocoena phocoena) reactions to weighted vertical…
