Abstract: A marine feed composition is described comprising microbially derived arachidonic acid (ARA) or ARA in the form of a triglyceride. The ARA is suitably produced by a fungus, such as of the genus Mortierella, although the feed composition itself is free of microbial cells. These forms of ARA have been found to give better growth and pigmentation promotion in marine organisms (shrimps and fish) than corresponding phospholipid forms of ARA from fish oil. The ARA can be in the form of an oil, e.g. an oil-in-water emulsion or may first be fed to larvae, rotifers or nauplii which are themselves included in a composition as "live" feed for larger organisms.
