Oil from transgenic Camelina sativacontaining over 25 %n-3 long-chain PUFA as the major lipid source in feed for Atlantic salmon ( Salmo salar)
Abstract Facing a bottleneck in the growth of aquaculture, and a gap in the supply and demand of the highly beneficial n -3 long-chain PUFA (LC-PUFA), sustainable alternatives to traditional marine-based feeds are required. Therefore, in the present trial, a novel oil obtained from a genetically eng...

Diet TCO had no negative impacts on the evaluated immune and physiological parameters of head kidney monocytes.
