Northern shrimp ( <i>Pandalus borealis</i> ) protein hydrolyzate and oil promote flesh pigmentation and growth in post-smolt Atlantic salmon ( <i>Salmo salar</i> )
Bibliographic record
Abstract
This study investigated the use of alternative ingredients obtained from Pandalus borealis by-products on flesh pigmentation and growth in post-smolt Salmo salar (initial weight of ~ 300 g). Four experimental diets were fed to fish in triplicate tanks for 16 weeks: a control diet and three other diets containing either synthetic astaxanthin, shrimp hydrolyzate, or shrimp oil. Fish that were fed the shrimp hydrolyzate diet exhibited higher red hue (based on L*a*b* data) when compared to fish fed the two other pigmented diets and had higher final weight. In addition, shrimp oil was found to be as efficient as artificial astaxanthin to increase the intensity of flesh pigmentation in Atlantic salmon. The shrimp hydrolyzate tested in our study provides an excellent source of astaxanthin and protein for Atlantic salmon. Likewise, shrimp oil could also constitute a natural source of astaxanthin and oil to this species.

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.
