Killer Whale Depredation and Associated Costs to Alaskan Sablefish, Pacific Halibut and Greenland Turbot Longliners
Killer whale (Orcinus orca) depredation (whales stealing or damaging fish caught on fishing gear) adversely impacts demersal longline fisheries for sablefish (Anoplopoma fimbria), Pacific halibut (Hippoglossus stenolepis) and Greenland turbot (Reinhardtius hippoglossoides) in the Bering Sea, Aleutian Islands and Western Gulf of Alaska. These interactions increase direct costs and opportunity co...

متن کاملKILLER WHALE (Orcinus orca): Eastern North Pacific - Alaska Resident Stock
STOCK DEFINITION AND GEOGRAPHIC RANGE Killer whales have been observed in all oceans and seas of the world (Leatherwood and Dahlheim 1978). Although reported from tropical and offshore waters, killer whales occur at higher densities in colder and more productive waters of both hemispheres, with the greatest densities found at high latitudes (Mitchell 1975, Leatherwood and Dahlheim 1978, Forney ...
متن کاملOut of the Pacific and Back Again: Insights into the Matrilineal History of Pacific Killer Whale Ecotypes
Killer whales (Orcinus orca) are the most widely distributed marine mammals and have radiated to occupy a range of ecological niches. Disparate sympatric types are found in the North Atlantic, Antarctic and North Pacific oceans, however, little is known about the underlying mechanisms driving divergence. Previous phylogeographic analysis using complete mitogenomes yielded a bifurcating tree of ...
متن کاملOrcinus orca – Killer Whale
Taxonomic notes: Orcinus orca is currently considered a single, cosmopolitan species, however many populations (including some which occur sympatrically) are ecologically, genetically and morphologically distinct (Rice 1998; Ford 2009). Despite such distinction, the global genetic diversity of the species appears low at both mitochondrial and nuclear DNA markers (Hoelzel et al. 2002; Morin et a...
