Outline of Final Research Achievements

We investigated the flow of substances from terrestrial plants that serve as food for invertebrates. In this study, we used a Direct Analysis in Real Time Mass Spectrometry that can be analyzed with simple pretreatment. In sea urchins and brackish-water clam, terrestrial plant-derived components were taken into the body and reflected in body components (e.g., stearic acid). We were unable to identify some of the substances detected in this study and will continue to analyze the data.

Academic Significance and Societal Importance of the Research Achievements

本研究は餌となる陸上植物から体成分への物質の流れを一部明らかにすることができた．陸上植物由来の成分が体内へ取り込まれ，同じ餌料であってもヤマトシジミとウニ類では検出される成分が異なっていた．検出された成分の中には機能性を持つものも検出されたことから，付加価値向上へも繋がる知見を得ることが出来た．餌確保が問題となっている漁業，養殖業の現場において新しい餌料の開発にも貢献するものと考える．
