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.
Claims46
A marine feed composition comprising one or more feed component(s) and/or ingredient(s) and microbially derived arachidonic acid (ARA) and the composition is substantially free of microorganisms that produce, or are capable of producing, ARA.
A marine feed composition comprising one or more component(s) and/or ingredient(s) and ARA where the ARA is in the form of a triglyceride and/or the composition is substantially free of ARA in phospholipids form and the composition is substantially free of microorganisms that produce, or are capable of producing, ARA.
A process for preparing a marine feed composition, the process comprising mixing microbially derived arachidonic acid (ARA), but not an organism used to derive the ARA, with one or more feed component(s) and/or ingredient(s), such that the composition is substantially free of microorganisms that produced, or are capable of producing, ARA.
A process for preparing a marine feed composition, the process comprising mixing ARA in the form of a tryglyceride with one or more feed component(s) and/or ingredient(s).
