Abstract

fetched live from OpenAlex

Atlantic salmon Salmo salar were infected with two levels of sea lice Lepeophtheirus salmonis (0·13 ± 0·02 and 0·02 ± 0·00 sea lice g −1 ). Once sea lice became adults, the ventral aorta of each fish was fitted with a Doppler cuff to measure cardiac output ( Q̇ ), heart rate ( f H ) and stroke volume ( V S ) during swimming. Critical swimming speeds ( U crit ) of fish with higher sea lice numbers [2·1 ± 0·1 BL (body lengths) s −1 ] were significantly lower ( P &lt; 0·05) than fish with lower numbers (2·4 ± 0·1 BL s −1 ) and controls (sham infected, 2·6 ± 0·1 BL s −1 ). After swimming, chloride levels in fish with higher sea lice numbers (184·4 ± 11·3 mmol l −1 ) increased significantly (54%) from levels at rest and were significantly higher than fish with fewer lice (142·0 ± 3·7 mmol l −1 ) or control fish (159·5 ± 3·5 mmol l −1 ). The f H of fish with more lice was 9% slower than the other two groups at U crit . This decrease resulted in Q̇ not increasing from resting levels. Sublethal infection by sea lice compromised the overall fitness of Atlantic salmon. The level of sea lice infection used in the present study was lower than has previously been reported to be detrimental to wild Atlantic salmon.

Teacher imitation

Not 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.
