A FEASIBILITY STUDY ON A MONITORING METHOD OF NON-MOVING ACUATIC ORGANISM USING ENVIRONMENTAL DNA

Abstract

 The seagrass bed monitoring method using environmental DNA (eDNA) can be established in the following cases. When sampling water is collected at a fixed point and the time change of the amount of eDNA is acquired, eDNA starting from a specific location does not coexist as eDNA from other starting points at the same time. In this study, we examined this feasibility by particle tracking calculation using simple bay model and the Ago bay model as a real sea. Using 10 types of simple bay models and the Ago bay model, it was confirmed that particles starting from a specific area appeared exclusively at the water sampling point depending on the flow pattern, and it was confirmed that this method might be established depending on the combination of seagrass distribution and flow of the bay.
