Harbour porpoises (Phocoena phocoena) stranding in large numbers around the southern North Sea with fatal, sharp-edged mutilations have spurred controversy among scientists, the fishing industry and conservationists, whose views about…
In September 2011, two harbour porpoises (Phocoena phocoena) presenting extensive traumatic lesions washed ashore in Belgium. Similar lesions, with large parts of skin and blubber missing, had not been recorded…
(...)Grey seals are generalist feeders, taking a wide variety of fish, mollusc, echinoderm, crustacean, and cephalopod prey (Bowen & Harrison, 1994; Hammond et al., 1994; Strong, 1996; Brown et al.,…
(...) gray seal (Halichoerus grypus) consumption of harbor porpoises—whether predation or scavenging—might reflect a change in gray seal feeding habits in the southern North Sea (Haelters et al. 2012), where…
1. Diet studies of marine mammals typically summarise prey composition across all individuals studied. Variation in individual diets is usually ignored, but may be more than just “noise” around an…
(...) Two separate predation events were documented off the coast of Vancouver Island, British Columbia between the years 2013-2014. Both predation events occurred on small cetaceans from the Phocoenidae family:…
The numbers of North Atlantic harbour porpoise (Phocoena phocoena) within the Bay of Fundy/Gulf of Maine were considered to be declining as a consequence of bycatch in the sink gillnet…
From an ecosystem management perspective, analysis of the functional roles of species is a challenge. It is valuable to determine which species are irreplaceable within a given community based on…
Harbour porpoises are widely distributed in the seas around Denmark. Total abundance in Danish waters is estimated as approximately 100,000 animals. Population density varies considerably by area. There are probably…
