Exploring trade-offs between fisheries and conservation of the vaquita porpoise (Phocoena sinus) using an Atlantis ecosystem model
Morzaria-Luna, Hem Nalini; Ainsworth, Cameron H.; Kaplan, Isaac C.; Levin, Phillip S.; Fulton, Elizabeth A.
PLoS ONE (2012)
Background: Minimizing fishery bycatch threats might involve trade-offs between maintaining viable populations and economic benefits. Understanding these trade-offs can help managers reconcile conflicting goals. An example is a set of…
Swimming patterns of wild harbour porpoises Phocoena phocoena show detection and avoidance of gillnets at very long ranges
Nielsen, T.P.; Wahlberg, M.; Heikkilä, S.; Jensen, M.; Sabinsky, P.; Dabelsteen, T.
Marine Ecology Progress Series (2012)
Harbour porpoises Phocoena phocoena are unintentionally caught in gillnets. Although the effectiveness of by-catch mitigation measures has been evaluated many times, only a few studies have investigated the behavioural patterns…

Records of harbour porpoises (Phocoena phocoena) in fishing nets during the interwar period in Poland: Verification of archival materials
Psuty, Iwona
Aquatic Mammals (2013)
The Polish fisheries administration registered incidents of harbour porpoises caught by fishermen from fishing bases within the country's borders between 1922 and 1938. These data are unique in the Baltic…
Using pingers to reduce bycatch of small cetaceans in Peru’s small-scale driftnet fishery
Mangel, Jeffrey C.; Alfaro-Shigueto, Joanna; Witt, Matthew J.; Hodgson, David J.; Godley, Brendan J.
Oryx (2013)
There is growing awareness that small-scale fisheries may have large impacts on threatened marine fauna. Bycatch of small cetaceans by the Peruvian small-scale driftnet fleet results in the deaths of…

Larsen, F.; Krog, C.; Ritzau Eigaard, O.
Endangered Species Research (2013)
A trial was conducted in the Danish North Sea hake gillnet fishery in July to September 2006 to determine whether the spacing of the Aquatec AQUAmark100 pinger could be increased…
Vaquitas and gillnets: Mexico’s ultimate cetacean conservation challenge
Rojas-Bracho, L; Reeves, RR
Endangered Species Research (2013)
There is a high risk that incidental mortality (bycatch) in gillnets will lead to extinction of the vaquita Phocoena sinus, a small porpoise endemic to Mexico’s northern Gulf of California.…
