| Outline of Final Research Achievements |
An evaluation method of fish inhabitation in agricultural canals was developed using DNA extracted from canals' water, environmental DNA (eDNA). In analyses for dojo loach and tamoroko, it was successful to estimate fish presence or absence through DNA detection of both species from eDNA. In analysis of Amur minnow, it was shown that eDNA could be used as an estimation method of abundance distribution of fish by comparing fish DNA volumes detected from eDNA with fish numbers caught by trap nets.
