The Agreement on Port State Measures to Prevent, Deter and Eliminate Illegal, Unreported and Unregulated Fishing (referred to in short as the Port State Measures Agreement (PSMA)) is a 2009 international treaty of the Food and Agriculture Organization (FAO) designed to prevent and eliminate illegal, unreported and unregulated fishing.

Content

The treaty requires that fishing vessels request permission to dock at a port and inform the port of the details of its fishing operations. Permission to dock can be denied if unregulated fishing occurred. The measure is intended to block illegally caught fish from entering the marketplace. Other measures in the treaty include inspections of equipment, paperwork, catches, and ship's records. Though the treaty does not compel countries to apply these measures to ships under their own flags, they may choose to do so under the agreement.^[1][2]
