Simulated seal scarer sounds scare porpoises, but not seals: species-specific responses to 12 kHz deterrence sounds

Mikkelsen, Lonnie; Hermannsen, Line; Beedholm, Kristian; Madsen, Peter Teglberg; Tougaard, Jakob
Royal Society Open Science (2017)

Acoustic harassment devices (AHD) or ‘seal scarers’ are used extensively, not only to deter seals from fisheries, but also as mitigation tools to deter marine mammals from potentially harmful sound…

Cox, T. M.; Read, A. J.; Barco, S.; Evans, J.; Gannon, D. P.; Koopman, H. N.; McLellan, W. A.; Murray, K.; Nicolas, J.; Pabst, D. A.; Potter, C. W.; Swingle, W. M.; Thayer, V. G.; Touhey, K. M.; Westgate, A. J.
Fishery Bulletin (1998)

We examined 107 harbor porpoise (Phocoena phocoena) carcasses recovered from beaches in Maryland, Virginia, and North Carolina between 1994 and 1996 for evidence of entanglement in fishing gear. Stranded porpoises…


Cetaceans and gillnet fisheries in Mexico, Central America and the wider Caribbean: A preliminary review

Vidal, O.; Van Waerebeek, K.; Findley, L. T.
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This paper reviews published and unpublished information on the mortality of cetaceans in gillnets in Mexico, Central America and the wider Caribbean.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…

Entrapment of harbour porpoises (Phocoena phocoena) in herring weirs in the Bay of Fundy, Canada

Neimanis, A. S.; Koopman, H. N.; Westgate, A. J.; Murison, L. D.; Read, A. J.
Journal of Cetacean Research and Management (2004)

Harbour porpoises (Phocoena phocoena) are small coastal cetaceans vulnerable to mortality in fishing operations. Not all interactions are fatal, however, and each year many porpoises swim into and are subsequently…


A global review of porpoise (Cetacea: Phocoenidae) mortality in gillnets

Jefferson, Thomas A.; Curry, Barbara E.
Biological Conservation (1994)

A global review of mortality of porpoises in gillnet fisheries indicates that individuals of all six species become entangled and die in gillnets. Harbor porpoises Phocoena phocoena are taken throughout…
