Measurement of Fish Habitat Use by Fish-Mounted Data Loggers for Integrated Coastal Management: An Example of Japanese Sea Bass (Lateolabrax japonicus) in Tokyo Bay

Effective integrated coastal management requires an understanding of how natural organisms use coastal areas, to protect those species. In this study, we used fish-mounted data loggers to examine the habitat use of the Japanese sea bass (Lateolabrax japonicus), a representative fish species in Tokyo Bay. Footage from the micro-video cameras on the fish showed Japanese sea bass swimming with other conspecifics. The three loggers obtained a time series of water temperature, salinity, swimming depth, and three-axis acceleration for a total of 60 h. These records indicated that the river, the ship port, and the fishing port were all important habitats for the Japanese sea bass. Based on our results, we discuss how such data can be used for conservation policies for natural organisms in integrated coastal management.
