In order to research the actual operation status of fishing vessels by AIS, an effective extraction method is needed even when vessel name, MMSI, and type of ship information are insufficient. In this study, we analysis on the illegal use of AIS for fishing pole to indicate the location of operations and proposes a method for estimating fishing grounds using AIS buoys. Extracted by Vendor ID and vessel name notation and visualized using the kernel density estimation to show the major fishing grounds. The use of AIS buoys is illegal, but if the reception rate of satellite AIS improves, it may be easier to determine the location of operations and prevent damage to fishing gear.
