| Outline of Final Research Achievements |
The purpose of this study is to develop a system to monitor activity of the Naru-eagle ray and to assess the impact on the shallow water ecosystem in Set-Inland Sea. We spent first two years (2014, 2015) to develop a procedure for effectively catching rays and attaching data-loggers to monitor its activity. In the third year (2016), using an animal-born video camera system with an activity logger, we develop an algorithm to classify detail behavior of the species such as flapping, gliding, resting or feeding on seafloor. In the last two years (2016, 2017), we analyzed relationships among their activity, seafloor environments, and other encountered fish species.
