This is a report on the evaluation of the profile of lipids from muscle of salmon as a tool to discriminate wild from farmed Atlantic salmon based on published data and on our original on-going research work using NMR-based profiling of lipids. Accordingly, the report is divided in two parts: one part based on published data that may be open and a second part based on our ongoing research that is confidential and has not been included in this short version. The fatty acid profiles of oils extracted from Atlantic salmon muscle always reflected the profile of the diet and even after a washing out period the n3/n6 ratio was not fully recuperated. Farmed from wild Atlantic salmon were easily differentiated by the ratio n3/n6 calculated as follows: [(C20:5n3+C22:5n3+C22:6n3)/C18:2n6], in those works were the composition of farmed and wild fish were provided. However, when combining the results of all the publications used for this review it lost is value. This may be due to differences in the analytical procedures used by different research groups, to the great differences in the composition of the farmed Atlantic salmon and also to the much larger number of farmed than wild Atlantic salmon examined here.
