TL;DR: The fatty acid composition of over 3,000 Scottish Atlantic salmon farmed between 2006 and 2015 is compared to find that terrestrial fatty acids have significantly increased alongside a decrease in EPA and DHA levels, and the nutritional value of the final product is compromised.

TL;DR: All the new sources have potentially important roles to play in increasing the supply of n-3 LC-PUFA so that they are available more widely and in higher concentrations providing more options and opportunities for human consumers to obtain sufficient EPA and DHA to support more healthy, balanced diets.

TL;DR: Transgenic Camelina sativa expressing algal genes was used to produce an oil containing n-3 LC-PUFA to replace fish oil in salmon feeds, which had no detrimental effects on fish performance, metabolic responses or the nutritional quality of the fillets of the farmed fish.

TL;DR: Inclusion of ECO did not affect any of the performance parameters studied and enhanced apparent digestibility of individual n-6 and n-3 PUFA compared to dietary WCO, but the regulation of a small number of genes could be attributed to the specific effect of ECO (311 features) with metabolism being the most affected category.

TL;DR: This review explores the technologies being applied to produce de novo n-3 LC-PUFA sources, namely microalgae and genetically engineered oilseed crops, and how they may be used in aquafeeds to ensure that farmed fish remain a healthy component of the human diet.
