Abstract: The exposure of illegal fishing by SouthSeafood Express Corp highlights the urgent need for better tools to monitor commercial fishing in Oceanus. In response, we develop an interactive visualization tool for the VAST Challenge’s Mini-Challenge 2. Our system analyzes the CatchNet knowledge graph, combining vessel tracking and port records from FishEye International, a non-profit dedicated to combating illegal fishing. The tool links vessels to probable cargos, identifies seasonal trends, and detects anomalies in port records. Detects suspicious activity of vessels, offering actionable insights to aid investigations and prevent future illegal fishing.
