Arachidonic acid in aquaculture feeds: current status and future opportunities

The importance of arachidonic acid (20:4n−6, ARA) in fish nutrition has tended to be overlooked in preference to eicosapentaenoic (20:5n−3, EPA) and docosahexaenoic acids (22:6n−3, DHA), probably due to the predominance of the latter two HUFA in fish tissues. However, despite the abundance of EPA and DHA in fish tissues, the importance of ARA as the primary eicosanoid precursor has been recognised for some time. Only very recently has the...
