Farmed Atlantic Salmon as Dietary Sources of Long-Chain Omega-3 Fatty Acids: Effect of High-Energy (High-Fat) Feeds on This Functional Food
Bibliographic record
Abstract
High energy diets are popular in today's salmon farming, but the lipid deposition in Atlantic salmon Salmo salar, particularly in steaks and fillets, and finally the effect of these diets on product quality, have not been examined. Over 12 months three commercial diets were fed, these being similar in all nutrients except the dietary fat levels (25, 29 and 31%). The muscle protein content was not modified by the three dietary treatments. Texture measurements and sensory panels were conducted on two specific sites in dorsal muscle steak cuts. A significant difference in muscle texture was found. There was a positive correlation between dietary fat and lipid deposition in the fish muscles. The total lipids in white muscle were, respectively, 1.27, 1.41and 2.25 %, in the trimmed steaks, 2.97, 4.58 and 5.38%, and in the whole steaks 5.45, 7.64 and 9.76%. The fatty acid composition analyses showed only a slight effect of diet on phospholipids rich in DHA. In the triacylglycerols the fatty acids reflected the dietary fatty acids with DHA and EPA at around 10% each. However, the DHA content slightly exceeded that of the EPA.

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.
