The
workshop was organized by the IUCN-SSC Sciaenidae Red List Authority, ICMBio (Instituto Chico Mendez de Conservação
da Biodiversidade, Ministério do Meio Ambiente, Brazil) and the IUCN Marine Biodiversity Unit’s Global Marine Species
Assessment Program, Old Dominion University, USA. At the workshop, 50 specialists from 25 countries were divided in four
working groups to share and synthesize species-specific data on each species taxonomy, distribution, population trends,
habitat, ecology, life history, impact of major threats and conservation measures to collectively apply the IUCN Red List
Categories and Criteria (version 3.1) and to assign each species a Red List Category.
