Abstract: Mysid Neomysis sp. was enriched with egg - yolk ( control group), microalga Phaeodactylum tricornutum, enrichment- 1 and enrichment- 2 for 0, 4, 8 and 12 hours and the fatty acid compositions in the enriched mysid were determined. The results showed that there were significant differences in fatty acid compositions in the mysid enriched with different materials and enrichment periods. The main profiles of the fatty acid in the mysid were 16:0, 18: In -9, eicosapentaenic acid (EPA) and docosahexaenic acid (DHA) before enrichment. The maximal EPA ( 15. 727% ), DHA ( 17. 072% ) and poly - unsaturated fatty acid ( PUFA, 45. 850% ) were observed in the mysid enriched with egg - yolk 0 hour after enrichment. The highest EPA( 18. 138% ) and DHA ( 17. 896% ) were found in the mysid enriched with the microalga 12 hours after enrichment. The mysid enriched with enrichment - 1 and enrichment - 2 had the highest EPA and DHA levels 8 hours after enrichment. There were the maximal PUFA in the mysid enriched with microalga (49. 421% ) for 4 hours, with enrichment - 1 (50. 603% ) for 8 hours and with enrichment- 2 group(49.938% ) for 4 hours. The enriched mysid starved showed significant decrease in saturated fatty acid (SFA) levels, but significant increase in PUFA levels, indicating that the mysid metabolized SFA first.
