Artificial reefs are important since they provide additional habitat leading to increasing abundance and biomass of marine biota. In a Bukchon artificial reef, Jeju Island, South Korea, environment data, artificial reef properties, and acoustic data in four seasons were integrated to visualize and examine their connections using a geographic information system (GIS). As a result, regarding the spatial and temporal distributions of fishes, January had the lowest Nautical Area Scattering Coefficient (NASC, m2/nm2) and June had the highest NASC, and relatively high NASC was observed from 5 to 30 m deep throughout seasons. The influential circle (effective distance from reef) …

Bio-logging and bio-telemetry are effective methods for monitoring the activity of aquatic animals. Tagging technology has recently advanced, and it is now possible to use tracking devices on small fish and multiple individuals. For species that live in schools such as small pelagic fish, analyzing the activity of multiple individuals may help to further our understanding of school activity in nature. In this study, we tracked the swimming depth of multiple individuals of schooling Pacific herring and examined whether the school’s characteristics and activity can be estimated from the individuals’ swimming depth in the laboratory and a set net experiment. …
