Stock Assessment Science and Methodology

Stock assessments provide the ability for scientists to evaluate changes in fish populations through time. For highly migratory species that travel thousands of miles, across entire ocean basins, this process is complex and technical. The Billfish Foundation is a global leader in funding stock assessment science and improving the methodologies used to make the assessments. Areas of TBF stock assessment work include the Atlantic Ocean, the Pacific Ocean, marlin bycatch in the Gulf of Mexico yellowfin tuna fishery, and more. Stock assessments provide the raw data for the decisions that govern how the oceans are managed. By improving methodology and accuracy, The Billfish Foundation empowers governments and policy makers to make good and sound decisions.
