UV-B light stimulates the production of Vitamin D3 in Atlantic salmon
Bibliographic record
Abstract
Vitamin D 3 was analysed in fish muscle during two separate production trials with Atlantic salmon in the freshwater phase. Each trial consisted of two groups exposed to UV-B light and two control groups. Fish were sampled at the start of the trial and after approximately 30 and 70 days. The groups exposed to UV-B light had 2,5 to 6 times higher Vitamin D 3 in the muscle after 4 weeks and more than 5 times as much after about 10 weeks than the control groups. The study suggests that Atlantic salmon in the freshwater phase synthesize pre-vitamin D 3 from 7-dehydrocholesterol using UV-B light in a larger extent than previously thought. In today's salmon farming, where more of the farming occurs in closed and submerged facilities with no or limited access to UV-B from natural sunlight, this knowledge is important.

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.
