Progress in Oceanography (2014)
The coastal Runnelstone Reef, off southwest Cornwall (UK), is characterised by complex topography and strong tidal flows and is a known high-density site for harbour porpoise (Phocoena phocoena); a European…
Trends in the maternal investment of harbour porpoises are uncoupled from the dynamics of their primary prey
Read, A. J.
Proceedings of the Royal Society B: Biological Sciences (2001)
Harbour porpoises in the Bay of Fundy and Gulf of Maine feed primarily on Atlantic herring. Herring stocks have undergone dramatic fluctuations in abundance over the past three decades due…

Nature (1997)
The most serious danger to dolphins and porpoises around the world is the threat from various forms of gill-net fishing. One potential way to reduce the number of deaths of…
Genetic and historic evidence for climate-driven population fragmentation in a top cetacean predator: The harbour porpoises in European water
Fontaine, M. C.; Tolley, K. A.; Michaux, J. R.; Birkun, A.; Ferreira, M.; Jauniaux, T.; Llavona, A.; Ozturk, B.; Ozturk, A. A.; Ridoux, V.; Rogan, E.; Sequeira, M.; Bouquegneau, J.-M.; Baird, S. J. E.
Proceedings of the Royal Society B: Biological Sciences (2010)
Recent climate change has triggered profound reorganization in northeast Atlantic ecosystems, with substantial impact on the distribution of marine assemblages from plankton to fishes. However, assessing the repercussions on apex…
Protected species bycatch estimating approaches: Estimating harbor porpoise bycatch in U.S. Northwestern Atlantic gillnet fisheries
Orphanides, C. D.
Journal of Northwest Atlantic Fishery Science (2010)
Harbor porpoise bycatch estimates for federally managed gillnet fisheries in northwestern Atlantic US waters were calculated for a nine-year period (1999–2007) using two new methods, and the results were compared…
The effect of acoustic harassment devices on harbour porpoises (Phocoena phocoena) in the Bay of Fundy, Canada
Johnston, Dave W.
Biological Conservation (2002)
Many salmon aquaculture sites in the Bay of Fundy employ acoustic harassment devices (AHDs) to deter seals from approaching fish pens. These devices may also exclude harbour porpoises (Phocoena phocoena)…
Fatal disseminated Toxoplasma gondii infection in a captive harbour porpoise (Phocoena phocoena)

Journal of Comparative Pathology (2015)
A 7-year-old female harbour porpoise (Phocoena phocoena), born and held in captivity, suffered from reduced consciousness, imprecise and circling swimming movements and long phases of immobility over a period of…
Cetacean abundance estimates in US northwestern Atlantic Ocean waters from summer 2011 line transect survey
Palka, D.
NEFSC Reference Document 12-29 (2012)
As part of the AMAPPS (Atlantic Marine Assessment Program for Protected Species) project, the Northeast Fisheries Science Center (NEFSC) and Southeast Fisheries Science Center (SEFSC) of NOAA Fisheries Service conducted…
Trends in abundance of the Gulf of Maine population of harbour porpoise
Olson, P. A.
Master's Thesis - University of Rhode Island (1996)
Hundreds of harbor porpoise die each year as bycatch in the Gulf of Maine's sink gillnet fishery. In recent years, concern has arisen whether the Gulf of Maine population of…
Mitigation of harbour porpoise (Phocoena phocoena) by-catch in the gillnet fishery in the lower Bay of Fundy
Trippel, Edward A.; Strong, Michael B.; Terhune, John M.; Conway, Jeremy D.
Canadian Journal of Fisheries and Aquatic Sciences (1999)
Demersal gill nets equipped with acoustic alarms reduced harbour porpoise (Phocoena phocoena) by-catch rates by 77% over those without alarms in the Swallowtail area of the lower Bay of Fundy…
