Chinook Salmon Overwinter Residency in the Strait of Georgia: Insights from Acoustic Telemetry
Bibliographic record
Abstract
Chinook salmon (Oncorhynchus tshawytscha) exhibit diverse life history strategies across freshwater rearing, ocean entry timing, marine migrations, and maturation timing. The marine migrations of Chinook salmon are poorly resolved in terms of space, time, and individual variation. In Chinook salmon populations from rivers draining into the Strait of Georgia, ocean-type juveniles spend their first summer at sea feeding and growing in the Strait (Quinn 2021; Quinn and Losee 2022). At an unresolved time after the first ocean summer, some juveniles emigrate to the continental shelf off the west coast of Vancouver Island and the outer Pacific coast of North America (Weitkamp 2010; Tucker et al. 2011). Other individuals remain resident in the Strait of Georgia for most or all of their marine life (O’Neill and West 2009; Chamberlin et al. 2011; Arostegui et al. 2017). There may also be an intermediate or “transient” migration strategy (Kagley et al. 2017), as migratory diversity is likely a continuum of strategies. Since migrants and residents likely encounter distinct feeding opportunities, predation risks, and fisheries exploitation (Quinn 2021; Quinn et al. 2022), it is important to determine if individual physiological condition influences migration behaviour.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
