Interannual and Spatial Variability in Maturity of Walleye Pollock Gadus chalcogrammus and Implications for Spawning Stock Biomass Estimates in the Gulf of Alaska.

open access: yesPLoS ONE, 2016
Catch quotas for walleye pollock Gadus chalcogrammus, the dominant species in the groundfish fishery off Alaska, are set by applying harvest control rules to annual estimates of spawning stock biomass (SSB) from age-structured stock assessments.

Survey of n-3 and n-6 polyunsaturated fatty acids in fish and fish products

open access: yesLipids in Health and Disease, 2012
Background The imbalance of the n-3/n-6 ratio in the Western diet is characterised by a low intake of n-3 long-chain (LC) PUFA and a concurrent high intake of n-6 PUFA. Fish, in particular marine fish, is a unique source of n-3 LC PUFA.

Application of the Gadidae Fish Processing Waste for Food Grade Gelatin Production

open access: yesMarine Drugs, 2021
Waste from fish cutting (heads, swim bladders, fins, skin, and bones) is a high-value technological raw material for obtaining substances and products with a wide range of properties. The possibility of using waste from cutting fish of the Gadidae family:

Spatial patterns of pollock and zooplankton distribution in the Pribilof Islands, Alaska nursery area and their relationship to pollock recruitment [PDF]

open access: yesICES Journal of Marine Science, 2002
Data from six years, September 1994-1999, of bio-acoustic surveys near the Pribilof Islands, Alaska, (AK), from which age-0 walleye pollock school and zooplankton patch locations have been extracted, were analysed using image-processing methods. Multiple passes along four transects in this major pollock nursery area were examined.

Climate forcing by battered-and-breaded fillets and crab-flavored sticks from Alaska pollock

open access: yesElementa: Science of the Anthropocene, 2019
The food sector is a significant contributor to greenhouse gas emissions, contributing 10–32% of global anthropogenic sources. Compared with land-based food production systems, relatively little is known about the climate impact of seafood products ...

Climate and Demography Dictate the Strength of Predator-Prey Overlap in a Subarctic Marine Ecosystem.

open access: yesPLoS ONE, 2013
There is growing evidence that climate and anthropogenic influences on marine ecosystems are largely manifested by changes in species spatial dynamics. However, less is known about how shifts in species distributions might alter predator-prey overlap and
