Abstract

fetched live from OpenAlex

In the spring of 2010, the Government of Canada invited PICES to participate in a Commission of Inquiry into the Decline of Sockeye Salmon in the Fraser River by considering how marine ecology may have affected their abundance. A major objective that was achieved in this report was to assemble, within an eight week period, as comprehensive a summary as was possible of what is known about Fraser River sockeye salmon (Oncorhynchus nerka) in the ocean. While much of this effort involved summarizing information published in data/technical reports and the primary literature, where necessary, original data have been re-examined and new analyses conducted to fulfill the terms of the Statement of Work. The compilation provides a background of knowledge against which to judge what can be known regarding the two major questions posed by the Cohen Commission to PICES:-Can the decline in Fraser River sockeye in 2009 be explained by the conditions the fish experienced in the marine environment?-Is there any evidence for declines in marine productivity or changes in Fraser River sockeye distribution that can be associated with the 15-year gradual decrease in Fraser River sockeye productivity?

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
