Global map of fishing vessel activity (IMAGE) University of California - Santa Cruz Caption This map shows the estimated total fishing vessel activity and the amount of this activity obscured by suspected disabling of automatic identification systems in areas with sufficient satellite reception. Areas with highest fishing vessel activity and the highest fraction of activity obscured by disabling occur in three regions of concern for illegal, unreported and unregulated fishing: near Argentina and West Africa, and in the Northwest Pacific. In contrast, fisheries in waters near Alaska are some of the most intensively managed in the world.
