Description
Summary:19–22 May 2022 Kyoto, Japan The catch of snow crab in the Sea of Japan has decreased. Therefore, there are many regulations including the size limitation and protected season, protected areas and production of fingerlings to enhance the resources. However, these measures may be insufficient to maintain and restore resources because the effect of the regulation was not evaluated very well. It is very difficult to observe the snow crab behaviors because they inhabited the deep-sea floor in the Sea of Japan. Therefor we began to investigate the challenging biotelemetry study in order to reveal their behaviors. In this paper, we introduced preliminary results of the deep-sea trials of Vemco positioning system (VPS). This was our first experience using the deep-sea VPS study.
