Pigmentation and Composition of Flesh of Atlantic Salmon Fed Diets Supplemented with the Yeast<i>Phaffia rhodozyma</i>
Bibliographic record
Abstract
In a pigmentation trial, Atlantic salmon Salmo salar in ocean pens were fed diets supplemented with the red yeast Phaffia rhodozyma, a control diet supplemented with synthetic astaxanthin, and a nonpigmented control diet. Yeast diets contained spray-dried untreated P. rhodozyma, heat-treated and spray-dried P. rhodozyma, and heat-treated and chemically treated spray-dried P. rhodozyma. Growth, weight, and fork length of all fish increased linearly with feeding and were not significantly different at the end of the study. Astaxanthin concentration in all pigmented fish increased linearly and ranged from 3.26 to 3.78 mg/kg after 150 d of feeding. Apart from the nonpigmented diet, astaxanthin concentration was not significantly different between fish fed the untreated or treated red yeast and those fed the synthetic astaxanthin diet (control). Assessment of astaxanthin isomers corroborated the assimilation of the (3R,3′R) isomer from all P. rhodozyma diets. Moisture, ash, and protein in all fish declined linearly with time, whereas lipid increased, but only during the first 30 d of feeding. Fatty acid profiles of all fish were virtually identical and independent of the source of pigment. No beneficial or adverse nutritional effects to the fish resulted from the use of modified red yeast.

How this classification was reachedexpand
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.
