The Pacific Halibut, Hippoglossus stenolepis, and Sablefish, Anoplopoma fimbria, Individual Fishing Quota Program: A Twenty-year Retrospective

Dispersal and behavior of Pacific halibut Hippoglossus stenolepis in the Bering Sea and Aleutian Islands region

Currently, it is assumed that eastern Pacific halibut Hippoglossus stenolepis belong to a single, fully mixed population extending from California through the Bering Sea, in which adult halibut disperse randomly throughout their range during their lifetime. However, we hypothesize that hali but dispersal is more complex than currently assumed and is not spatially random. To test this hypo thesi...

Recovery of visual function in Pacific halibut (Hippoglossus stenolepis) after exposure to bright light

Atlantic halibut - Hippoglossus hippoglossus

Distribution Th e Atlantic halibut is distributed throughout the northern part of the Atlantic Ocean and in parts of the Arctic Ocean (Fig.1) (1). Th e species is particularly abundant along the Norwegian coast, the Faroe Islands, Iceland, and southern Greenland. It may also be encountered in the North Sea and the western part of the Baltic Sea. Along the east coast of North America, the halibu...

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...

Stable isotope variations in otoliths of Pacific halibut (Hippoglossus stenolepis) and indications of the possible 1990 regime shift

Stable oxygen and carbon isotope ratios ( 18O and 13C) from archived otoliths of Pacific halibut, Hippoglossus stenolepis, were measured to examine the most recent regime shifts in British Columbia and the Gulf of Alaska. 18O values of these otoliths ranged from −1.5 to +2.8‰ VPDB, and were consistent with the life stages and migration behavior of halibut. 13C varied from −3.3 to +0.9‰ VPDB, bu...
