Evaluating the Effects of Dam-Altered Flow Regimes on the Swimming Activity, Behaviour and Survival of Adult Sockeye Salmon (Oncorhynchus nerka)
Bibliographic record
Abstract
Anadromous adult Pacific salmon (Oncorhynchus spp.) encounter hydraulically challenging areas of difficult passage (high-gradient reaches, dams) during their reproductive migration.While the direct effects of dam operations on wild fishes are well documented (e.g., delayed movements, excessive energy-use), comparatively little is known as to the delayed, post dam passage effects of these barriers.Using acoustic accelerometer transmitters and model selection analyses, Chapter 2 assessed how managed flow releases from a dam influenced the swimming activity, behaviour and passage success of sockeye salmon (O.nerka).Building on this framework, Chapter 3 explored the potential for high-flow-induced burst swimming below the dam to predict the mortality of sockeye salmon.Findings from this research provide novel insight into the mechanisms that contribute to the delayed mortality of migratory fishes.Future studies investigating the indirect effects of dams will improve our ability to provide effective passage solutions to watersheds that are impacted by hydropower development.

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.
