Indications that algal blooms may affect wild salmon in a similar way as farmed salmon
Bibliographic record
Abstract
Based on a four year study conducted in Cowichan Bay, Canada, potential linkages between composition and abundance of phytoplankton and the feeding and histopathology of juvenile salmon were noted. During two dense blooms (Skeletonema spp. and Pseudo-nitzschia spp.), feeding of juvenile Chinook salmon decreased (n=202, empty stomachs >50%). All collected salmon gills (n=5) were damaged following high levels of mechanically harmful Chaetoceros convolutus in the water column; all collected livers (n=5) showed signs of pathological changes during Octactis speculum bloom. These observations were consistent with effects previously reported from salmon farms, however this agreement must be treated with caution as it is based on a limited number of samples. We suggest that there is a need for comprehensive studies to evaluate the potential role of harmful algae as a stressor to wild fish in a coastal environment.

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; both teacher heads agree on what is shown here.
