A Catch Documentation Scheme helps determine whether fish originate from catches that comply with applicable national, regional and international conservation and management measures, established in accordance with relevant international obligations. These Voluntary Guidelines for Catch Documentation Schemes were elaborated in response to concerns expressed over the continued threat to marine habitats and ecosystems represented by illegal, unregulated and unreported fishing, and the negative impact that these activities have on food security and national economies, particularly in developing regions. The guidelines were officially adopted by the FAO Conference at its Fortieth Session in July 2017.
