Environment impact assessment is required to install device of marine renewable energy. Particularly, tidal and oceanic current turbines may affect marine organisms. More specifically, striking risk with marine species and the turbines is concerned by local fishermen. To clarify its risk, there are several observations in the actual test site as well as water tank tests. Among them, Taya (2015) and Zhang et al. (2017) conducted a laboratory-scale experiment. Based on their research, this paper shows additional experimental conditions and discussed how fish behaves around a turbine blade. In addition, we showed an underwater fish-eye camera is an effective method to monitor fish around the device.
