A Synthesis of Laaquda$\hat{\mathbf{x}}$ (Northern Fur Seal) Community Surveys and Commercial Fishery Data in the Pribilof Islands Marine Ecosystem, Alaska

Journal of Marine Science and Engineering, 2022
Indigenous communities on the Pribilof Islands have longstanding cultural and economic ties to their marine ecosystem and, in particular, to laaqudan (in Unangam Tunuu) or northern fur seals (NFS; Callorhinus ursinus).

PCR Cloning Combined With DNA Barcoding Enables Partial Identification of Fish Species in a Mixed-Species Product

Frontiers in Ecology and Evolution, 2020
DNA barcoding is a valuable tool for regulatory identification of fish species; however, it does not perform well when multiple species are present within the same food product. Therefore, the objective of this study was to examine the use of PCR cloning

Identification of Atlantic Cod (Gadus morhua), Ling (Molva molva), and Alaska Pollock (Gadus chalcogrammus) by PCR–ELISA Using Duplex PCR [PDF]

Journal of Agricultural and Food Chemistry, 2014
Species-specific PCR-ELISA assays for the identification of Atlantic cod (Gadus morhua), Alaska pollock (Gadus chalcogrammus), and ling (Molva molva) in food products have been developed. The method, comprising a set of primers common to the first two species, a set of primers for M.

Using a climate attribution statistic to inform judgments about changing fisheries sustainability

Scientific Reports, 2021
Sustainability—maintaining catches within the historical range of socially and ecologically acceptable values—is key to fisheries success. Climate change may rapidly threaten sustainability, and recognizing these instances is important for effective ...

Insight into the Population Genetics of the Walleye Pollock Gadus chalcogrammus (Pallas, 1814) in the Northwestern Pacific from Microsatellite Multiplex Assay Study

Diversity
The walleye pollock, Gadus chalcogrammus (Pallas, 1814), is one of the most commercially and ecologically valuable species in the Northwestern Pacific. However, combined pressures of overfishing and environmental changes have led to a substantial decline

Causal Models as a Scientific Framework for Next‐Generation Ecosystem and Climate‐Linked Stock Assessments

Fish and Fisheries, Volume 27, Issue 4, Page 942-959, July 2026.
ABSTRACT Rapid changes in marine ecosystems highlight the need to account for time‐varying productivity in stock assessments used to support fisheries management. Common approaches incorporate annual variation or regressing processes such as recruitment, natural mortality, or growth on environmental variables.
