The IGFA Great Marlin Race is the world's largest citizen-science satellite tagging program for billfish, bringing together anglers and scientists to unlock the mysteries of these incredible fish. Since 2011, more than 711 satellite tags deployed across 25 countries have generated over 1.5 million nautical miles of migration data, advancing groundbreaking research that is helping shape the future of billfish conservation around the world.

While tag sponsorships cover the equipment and satellite transmissions, they do not fund the science that transforms raw data into discoveries. Your generous gift provides the research, analysis, and program support needed to turn every tagged fish into knowledge that benefits fisheries, managers, and future generations.

Together, we can ensure every tag tells a story that helps protect billfish for generations to come. Please make your generous gift today.
