Abstract
The present invention relates to feedstuffs for use in aquaculture, as well as methods for producing said feedstuffs. The invention also provides methods for rearing fish and/or crustaceans. In particular, the present invention provides a method of rearing a fish or crustacean, the method comprising feeding the fish or crustacean a feedstuff comprising lipid, the fatty acid of said lipid comprising at least 5.5% (w/w) stearidonic acid (SDA).
Claims60
A method of rearing a fish or crustacean, the method comprising feeding the fish or crustacean a feedstuff comprising lipid, the fatty acid of said lipid comprising at least 5.5% (w/w) stearidonic acid (SDA).
A feedstuff suitable for a fish or crustacean, the feedstuff comprising lipid, the fatty acid of said lipid comprising at least 5.5% (w/w) stearidonic acid (SDA).
A fish, wherein the fatty acid of the white muscle lipid of said fish comprises less than 29.6% SFA and at least 18.3% DHA.
A fish, wherein the fatty acid of the red muscle lipid of said fish comprises less than 28.2% SFA and at least 9.6% DHA.
A fish or crustacean, wherein the fatty acid of the muscle lipid of said fish or crustacean comprises at least 2.7% SDA.
A fish, wherein the fatty acid of the white muscle lipid of said fish comprises at least 2.1% SDA.
A method for producing a feedstuff for fish and/or crustaceans, the method comprising admixing oil obtained from a plant with at least one other ingredient, wherein the fatty acid of said oil comprises at least 5.5% (w/w) SDA.
A method for producing a feedstuff for fish and/or crustaceans, the method comprising admixing a transgenic organism, or extract or portion thereof, with at least one other ingredient, wherein the organism is genetically modified such that it produces SDA and/or produces higher levels of SDA than when compared to a corresponding non-transgenic, wild-type organism.
A cotton or flax plant capable of producing seed, wherein the oil of said seed-comprises fatty acid comprising at least 5.5% SDA on a weight basis.
A cotton or flax plant capable of producing seed, wherein the seed synthesizes GLA that is the product of M-desaturation of LA and/or SDA that is the product of M-desaturation of ALA, and wherein the efficiency of conversion of LA to GLA and/or ALA to SDA in the seed is at least 25% or at least 45%.
