Red Snapper in the Gulf of Mexico and U.S. South Atlantic: Data, Doubt, and Debate
Abstract Stock assessments provide fisheries managers with information that is used in the regulation of a fish stock. Assessments often rely upon a wide array of biological and fisheries data of varying quantity and quality, making the assessment process data hungry, complex, and uncertain. Assessm...
