Changes in the long-term distribution of commercially caught Cowichan chinook
Bibliographic record
Abstract
The Cowichan River, British Columbia (BC), Canada stock of Chinook Salmon (Oncorhynchus tshawytscha) is used federally in Canada, as an escapement indicator of the Lower Georgia Strait (BC) Chinook and as such is important both locally and internationally as part of the Pacific Salmon Treaty. The study examines the changes in distribution of catch of Cowichan hatchery Chinook from 1977-2011, using coded wire data. Regression analysis of SST and percentage of total catch when looked at by regime revealed different strengths of correlation for different areas. Statistically significant results occurred more often in the highly productive Regime 1 (1977-1988) for the west coast of Vancouver Island. SST one year prior to catch showed correlations to catch distribution more frequently than when compared to SST at brood year, sea entry year, or catch year. These population specific results can be compared to other populations to help tailor decisions around changing population dynamics in order to best manage stock-specific fisheries.

Full frame machine prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
