Visual Performance and Ocular System Structure of Kokanee and Sockeye Salmon following Strobe Light Exposure
Bibliographic record
Abstract
Abstract The use of flashing strobe lights to deter salmon from dam intakes and other hazardous underwater structures has become an appealing method for reducing salmon mortalities. However, no research has been carried out to determine how strobe light emission could affect the visual system of salmonid fishes. The present study investigated behavioral and ocular system changes after short-term (1- and 5-min) and long-term (3-h) exposure of kokanee and sockeye salmon (the lacustrine and anadromous forms of Oncorhynchus nerka). The onset of the escape response to an overhead shadow was different between treatments. Fish exposed for 1 or 5 min showed a response within 5 and 25 min of treatment, respectively, whereas the 3-h-exposed sockeye salmon responded a minimum of 64 h postexposure. All the retinas and lenses examined showed the same characteristics regardless of treatment. We conclude from these results that strobe exposure for 1 min or more induces a state of torpor in sockeye salmon, but exposure for no longer than 5 min does not induce permanent damage to the ocular system.

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.
