 note = {application/pdf, Moon jelly Aurelia coerulea has been gaining attention as a new production target species in Japan because of its increasing demand as a feed candidate for larval finfishes and shrimps and as an exhibit animal in an aquarium. In this study, rearing experiments of A. coerulea ephyrae using Artemia franciscana nauplii enriched with several oils containing various fatty acids (FA) as feed were conducted to evaluate the FA requirement of this species. As a result of two rearing experiments, feeds not containing DHA gave unfavorable growth rates compared to feeds with DHA, and the highest growth rate was obtained in feeds enriched with EPA:DHA=62:38 oil (DHA/EPA ratio of 0.6). These results indicate the importance of dietary FAs, especially EPA and DHA, on the somatic growth of A. coerulea ephyra and EPA may play a more crucial role than DHA to maximize the growth of the ephyrae. This study is the first to provide a criterion of suitable FAs composition in a feed for the efficient production of this species under artificial breeding., ミズクラゲAurelia coerulea のエフィラ幼生について，高度不飽和脂肪酸を含む油脂を用いて脂肪酸強化されたアルテミアを給餌する飼育試験を行い，脂肪酸要求特性について調査した。飼育試験の結果，DHA を含まない試験区ではエフィラ幼生に対する成長阻害が確認された。さらにこの試験区では，対照区の個体と比較して口腕部が真直するといった発達異常が観察された。餌料中の異なるDHA/EPA 比がエフィラ幼生の成長に与える影響を調査した試験では，DHA/EPA 比が0.6 の試験区において最も高い成長率が得られた。これらの結果から，餌料に含まれるDHA およびEPA 含量が，ミズクラゲのエフィラ幼生期の成長，生残に対して正の影響を及ぼすことが明らかとなった。},
