​Dr. Shinji Takahashi from Tohoku University, together with the Molecular Ecology and Health Laboratory members Mr. Arthien Pelingen (Researcher), Mr. Karim Clivaz (M2), and Mr. Tsubasa Moriya (B4), collected environmental DNA (eDNA) and macroinvertebrates from Tenryu River, Shizuoka Prefecture on November 9-11, 2022.

​This recently concluded field work also serves as a follow-up of the August collection trip this year (Read here: collaborative-fieldwork-of-three-universities-in-kizu-and-tenryu-rivers.html). Accordingly, we focused on (1) identifying Ayu (Plecoglossus altivelis altivelis) spawning sites and on (2) observing macroinvertebrate distribution in relation to the riverine spatial habitat diversity. 
​On this three-day activity, we have successfully confirmed spawning of Ayu this season and positively identified different habitat types as we recorded various environmental parameters such as water temperature, pH, turbidity, etc. to be correlated in several macroinvertebrate studies.
