Enhanced protein synthetic capacity in Atlantic cod (<i>Gadus morhua</i>) is associated with temperature-induced compensatory growth
Bibliographic record
Abstract
Atlantic cod (Gadus morhua) were held either at seasonal ambient temperatures (-0.3 to 11 degrees C) or at a relatively constant control temperature (8-11 degrees C) to investigate aspects of protein synthesis during a period of compensatory growth. Protein synthesis rate, total RNA, and RNA-specific protein synthesis rate were determined in white muscle and liver when ambient temperatures were -0.3, 4.5, and 11 degrees C in February, June, and July, respectively. To allow for comparisons between treatment temperatures, fish were also acutely transferred to a comparable assay temperature in February and June. Over the transition from 4.5 to 11 degrees C (June to July), the ambient-held cod had a significant increase in size and a substantially higher growth rate relative to control-held fish over the same period, consistent with cold-induced compensatory growth. During the onset of this enhanced growth, in June when ambient temperature was approximately 4.5 degrees C, ambient-held fish elevated their capacity for protein synthesis in the white muscle and liver via elevation of the RNA content. When ambient temperature reached the same point as for the control fish (11 degrees C), the rate of white muscle protein synthesis remained higher in the ambient-held vs. that in the control-held fish, a process facilitated by elevated RNA content and greater RNA-specific rate of protein synthesis. In the liver, all measured characteristics of protein synthesis were the same for ambient and control fish in July. The latter suggests that compensatory growth may be in part explained by improved efficiency of protein synthesis.

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.
