Do walleye pollock exhibit flexibility in where or when they spawn based on variability in water temperature?

open access: yes, 2012
Environmental variability is increasingly recognized as a primary determinant of year-class strength of marine fishes by directly or indirectly influencing egg and larval development, growth, and survival.

Variation in the distribution of walleye pollock (Theragra chalcogramma) with temperature and implications for seasonal migration

open access: yes, 2005
Aspects of the feeding migration of walleye pollock (Theragra chalcogramma) in the eastern Bering Sea (EBS) were investigated by examining the relationship betweentemperatures and densities of fish encountered during acoustic and bottom trawl surveys ...

Responses of the Northern Bering Sea and Southeastern Bering Sea Pelagic Ecosystems Following Record‐Breaking Low Winter Sea Ice

open access: yesGeophysical Research Letters, 2019
Bering Sea sea ice during winter 2017–2018 was the lowest ever recorded. Ecosystem effects of low ice have been observed in the southeastern Bering Sea, but never in the northern Bering Sea.

The effects of ocean acidification on walleye pollock (Theragra chalcogramma) early life history stages [PDF]

open access: yes, 2014
Thesis (M.S.) University of Alaska Fairbanks, 2014Since the Industrial Revolution of the late 1700's, atmospheric and marine carbon dioxide levels have drastically increased.

An allometric smoothing function to describe the relation between otolith and somatic growth over the lifespan of walleye pollock (Theragra chalcogramma) [PDF]

open access: yes, 2007
We propose a new equation to describe the relation between otolith length (OL) and somatic length (fork length [FL]) of fish for the entire lifespan of the fish.

Using acoustic data from fishing vessels to estimate walleye pollock (Theragra chalcogramma) abundance in the eastern Bering Sea

open access: yes, 2011
Eastern Bering Sea walleye pollock ( Theragra chalcogramma ) support one of the world’s largest fisheries. Because of walleye pollock’s high recruitment variability and relatively short life span, timely and accurate abundance indices are needed for ...

Estimating movement with a spatially-explicit stock assessment model of eastern Bering Sea walleye pollock, Theragra chalcogramma [PDF]

open access: yes, 2007
Thesis (M.S.) University of Alaska Fairbanks, 2007The standard Eastern Bering Sea (EBS) walleye pollock (Theragra chalcogramma) stock assessment model has no spatial dimension.

Feeding and growth of seasonal cohorts of larval walleye pollock (Theragra chalcogramma) in Auke Bay, Alaska [PDF]

open access: yes, 1989
Thesis (M.S.) University of Alaska Fairbanks, 1989Larval walleye pollock, Theragra chalcogramma (Pallas), typically occur in the water column in synchrony with peak densities of prey.
