Cardiorespiratory status of triploid brown trout during swimming at two acclimation temperatures
Bibliographic record
Abstract
At 14° C, standard metabolic rate (75·1 mg O 2 h −1 kg −1 ), routine metabolic rate (108.8 mg O 2 h −1 kg −1 ), active metabolic rate ( c . 380 mg O 2 h −1 kg −1 ), critical swimming speed (U crit 1·7 BL s −1 ), heart rate 47 min −1 ), dorsal aortic pressure (3·2 kPa) and ventilation frequency (63 min −1 ) for triploid brown trout Salmo trutta were within the ranges reported for diploid brown trout and other salmonids at the same temperature. During prolonged swimming ( c . 80% U crit ), cardiac output increased by 2·3‐fold due to increases in heart rate (1·8‐fold) and stroke volume (1·2‐fold). At 18° C, although standard and routine metabolic rates, as well as resting heart rate and ventilation frequency increased significantly, active metabolic rate and certain cardiorespiratory variables during exercise did not differ from those values for fish acclimated to 14° C. As a result, factorial metabolic scope was reduced (2·93‐fold at 18° C v . 5·13‐fold at 14° C). Therefore, it is concluded that cardiorespiratory performance in triploid brown trout was not unusual at 18° C, but that reduced factorial metabolic scope may be a contributing factor to the mortality observed in triploid brown trout at temperatures near 18° C.

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; a candidate call from one teacher head, not a consensus.
