(NC) and Malaysian Chlorella sp. (CR). The prominent fatty acids of the bivalves were 16:1n-7, 18:1n-9, 18:1n-7, 18:3n-3, 20:5n-3, and 22:6n-3. The n-3 highly unsaturated fatty acid (HUFA) levels in C.japonica considerably differed with their habitats, gravel or muddy regions. The brackish bivalve, C.japonica, obtained from the gravel region contained n-3 HUFA such as 22:6n-3 as much as the marine bivalve T.philippinarum. Where-as the C.japonica obtained from the muddy region contained lesser proportion of 22:6n-3 than that from the gravel region. The dominant fatty acids of the algae were 16:0 (NC 8.6%, CR 8.6%), 16:1n-7 (NC 13.2%), 16:1n-9 (CR 4.9%), 18:2n-6 (CR 11.4%), 18:3n-6 (CR 8.2%), 18:3n-3 (CR 26.3%), 20:4n-6 (NC 5.6%), and 20:5n-3 (NC 39.3%). The Malaysian CR possessed 18:2n-6, 18:3n-6, and 18:3n-3 and only very small amounts of n-3 HUFA in contrast to the Japanese NC containing large amounts of n-3 HUFA such as 20:5n-3 and 20:4n-6. This suspects that the rotifer cultured with Malaysian CR have a low nutritive value for marine fishes which strictly require n-3 HUFA as an essential fatty acid.}, pages = {137--149}, title = {Fatty Acid Details for Bivalves, Tapes philippinarum and Corbicula japonica, and Marine Types of Algae, Nannochloropsis sp. and Chlorella sp.}, volume = {39}, year = {} }
