Cardiorespiratory modifications, and limitations, in growth hormone transgenic Atlantic salmon (Salmo salar)
Bibliographic record
Abstract
GH transgenic Atlantic salmon transgenic grew 3.6x faster than non-transgenic controls, and most aspects of their cardiorespiratory system were upregulated. For example, they had greater resting and post-stress catecholamine levels, higher post-stress haemoglobin concentrations, increased maximum heart performance, and elevated aerobic enzyme activities. However, they had a higher routine metabolic rate without a change in maximum metabolic rate (M02111ax), resulting in a decreased metabolic scope, and subsequently a lowered critical swimming speed. Overall, this study supports the theory of symmorphosis, in that most aspects of the transgenic's cardiorespiratory system are upregulated to accommodate the additional demands of higher growth and/or activity. However, the transgenics MO2max appears to be limited by their gill surface area, which was not upregulated. Further, it provides information on "their physiology that can be used to: 1) understand their needs in an aquacultural setting; and 2) infer the possible ecological consequences of their escape.

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.
