Seasonal Effects of Suspended Sediment on the Behavior of Juvenile Atlantic Salmon
Bibliographic record
Abstract
Abstract Short‐term increases in suspended sediment levels significantly influenced the behavior of juvenile Atlantic salmon in both fall and winter trials. The initial introduction of sediment (20 mg/L, or ≈15 nephelometric turbidity units [NTU]) increased foraging activity, which subsequently declined at sediment levels greater than 180 mg/L (≈35 NTU). Cover use also declined as fish emerged to forage. No fish returned to cover at sediment levels greater than 60 mg/L (≈22 NTU) in the fall trials, whereas some fish in the winter trials never emerged from cover. A rapid decline in territorial behavior and an avoidance response (i.e., alarm reaction) at sediment levels ranging from 60 to 180 mg/L (≈22‐42 NTU) were also noted in fall trials but not winter trials. Seasonal differences in the response of juvenile Atlantic salmon to suspended sediments may be explained by temperature‐related changes in diel activity patterns.

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.
