Determination of n-3 HUFA content in Atlantic salmon flesh based on the lipid content, morphometric measurements and blood fatty acid composition: A modeling approach
Fish are the most important source of n-3HUFA in the human diet and, with declining wild stocks, an increasing proportion is being provided by aquaculture. Paradoxically fish diets have traditionally used fish oil and meal themselves derived from wild fisheries. Continued aquaculture development req...

Fish are the most important source of n-3HUFA in the human diet and, with declining wild stocks, an increasing proportion is being provided by aquaculture. Paradoxically fish diets have traditionally used fish oil and meal themselves derived from wild fisheries. Continued aquaculture development requires fish oil to be replaced with vegetable oils, the only sustainable alternative. However, vegetable oils lack n-3 HUFA and so flesh from fish reared on these diets can also have reduced n-3 HUFA and thus reduced nutritional quality. This accepted, flesh n-3 HUFA content should be an economically important trait, but to be included in the breeding goal the trait must be measurable. In the present study, we investigated whether flesh n-3 HUFA content of salmon can be estimated in a non-fatal way. We showed that a general regression model based on flesh lipid content, morphometric and blood fatty acid measurements could estimate and predict flesh n-3HUFA content. This would allow a choice from a range of selection methods, including mass selection or within family selection, if this important flesh quality trait would be included in future breeding programmes for salmon. |
