dc.description.abstract | This experiment was conducted to evaluate the quality of rotifer enriched with four kinds of ennchement materials from the stand point of essensial fatty acids. Rotifer was enriched at 24 - 25°C for 18 hours at a density of 1000 ind/ml. Rotifers were treated by four kinds of enrichment materials such as oleic acid (R-OA), two different density of Nannochloropsis oculata, (4xl07 and 16x 107 cell/ml; R-N18 and R-N42) two different levels of eicosapentaenoic acids (EPA) triglyceride type (EPA-TAG) (20 and 40 µl/ml; R-E20, R-E40) and two different level of EPA ethyl ester (EPA-EE) (R-EE2S and R-EE5G%) respectively. Rotifers enriched with Nannocfiforopsis oculata and EPA-EE type have a similar profile of essensial fatty acid especially on n3-HUFA that dominated by EPA, while DHA was in a trace amount or not detected. In addition Nannochloropsis oculata as an enrichment material showed the highest population density of rotifers during enrichment periods. Rotifer enriched with EPA-TAG has a more complete of essential fatty acid profile compared to other enrichment materials due to their contained both of EPA and DHA. We conclude that rotifer enriched with EPA-TAG as enrichment material showed the best nutritional quality of rotifers from the stand point of essential fatty acid | en |
