Long-Term Changes in Length at Maturity of Pacific Salmon in Auke Creek Alaska

Although decreasing length at maturity has been observed in some Alaska salmon populations, the generality of this trend is poorly understood. This study was undertaken to determine whether this pattern holds for multiple species of salmon from a small

Alaska Fisheries Science Center's Auke Bay Laboratories Data Sets

Many data sets have been collected by Auke Bay Laboratories over the years. For our purposes, a data set is defined as a collection of data records organized around a common attribute. A data set is created by converting raw data into records. Raw data

Genetics Research in Alaska

We conduct a variety of genetic research on Pacific salmon, groundfish, and forage fish species to comply with regional, national, and international agreements and treaties for managing marine resources.

Salmon Research in Alaska

Pacific salmon play an important role in Alaska’s marine ecosystems and are a valuable commercial, recreational, and subsistence resource. NOAA Fisheries scientists forecast salmon harvests, assess the impact of commercial fisheries on salmon, and

Climate-Induced Trends in Predator–Prey Synchrony Differ Across Life-History Stages of an Anadromous Salmonid

Differential climate-induced shifts in phenology can create mismatches between predators and prey, but few studies have examined predator–prey mismatch across multiple life-history stages. We used long-term data from a warming stream with shifting

Otolith Shape Variability and Associated Body Growth Differences in Giant Grenadier, Albatrossia Pectoralis

Fish stocks can be defined by differences in their distribution, life history, and genetics. Managing fish based on stock structure is integral to successful management of a species because fishing may affect stocks disproportionately. Genetic and

Genetic stock composition analysis of the Chinook salmon bycatch from the 2015 Bering Sea walleye pollock (Gadus chalcogrammus) trawl fishery

A genetic analysis of samples from the Chinook salmon (Oncorhynchus tshawytscha) bycatch of the 2015 Bering Sea-Aleutian Island (BSAI) trawl fishery for walleye pollock (Gadus chalcogrammus) was undertaken to determine the overall stock composition of the

Genetic Stock Composition Analysis of Chum Salmon from the Prohibited Species Catch of the 2015 Bering Sea Walleye Pollock Trawl Fishery and Gulf of Alaska Groundfish Fisheries

A genetic analysis of the prohibited species catch (PSC) of chum salmon (Oncorhynchus keta) collected during 2015 from the federally managed walleye pollock (Gadus chalcogrammus) trawl fishery in the Bering Sea and from the federal groundfish fisheries in

Genetic Stock Composition Analysis of Chum Salmon from the Prohibited Species Catch of the 2016 Bering Sea Walleye Pollock Trawl Fishery and Gulf of Alaska Groundfish Fisheries

A genetic analysis of the prohibited species catch (PSC) of chum salmon (Oncorhynchus keta) collected during 2016 from the federally managed walleye pollock (Gadus chalcogrammus) trawl fishery in the Bering Sea and from the federal groundfish fisheries in

Evolution of Phenology in a Salmonid Population: a Potential Adaptive Response to Climate Change

Accumulating evidence has indicated that many fish populations are responding to climate change through shifts in migration time, but genetic data identifying the role of evolution in these shifts are rare. One of the first demonstrations of evolution of
