Identifying Hydraulic Characteristics Related to Fishery Activities Using Numerical Analysis and an Automatic Identification System of a Fishing Vessel

Many countries worldwide promote artificial reef projects to increase and preserve fishery resources; however, how reefs form fisheries is unclear. Nevertheless, specific hydraulic features of may attract fish. We selected an underwater as a research site clarify this hypothesis. In study, environmental conditions around the were modeled quantitatively assessed using numerical analysis. identified two related fish attraction: wake region local upwelling region. Their spatial distributions superimposed on path fishing vessel that was monitored automatic identification system (AIS). showed various characteristics (such region, flow velocity) in can be evaluated. Increasing amounts information from AIS used identify most therefore improve productivities reefs.
