Abstract
Current procedures for optimising the presentation of dietary polyunsaturated fatty acid (PUFA) to marine fish larvae are reviewed in relation to the advantages and disadvantages of using (a) single-cell eukaryotic organisms or, (b) purified oils, as primary sources of these essential nutrients in larval production systems. For the former option (a), phototrophic and heterotrophic organisms can both be used to advantage and current knowledge of the origins and functions of PUFA in marine organisms can help identify suitable organisms. For the latter option (b), control of PUFA peroxidation by various antioxidant systems is essential. Progress in this field requires definition of the optimal dietary ratio of 22:6(n-3): 20:5(n-3): 20:4(n-6); the significance of phospholipid vs. neutral lipid in larval diets, and larval requirements for antioxidant vitamins.
