This research investigates organizational diversity within Community Supported Fisheries (CSFs) in North America. Generally understood as the direct marketing of seafood through pre-arranged deliveries, CSFs have increased in number and geographic distribution since their origin in 2007. Despite, or because of, this rapid growth, fundamental questions remain unanswered about what organizational structures and business practices currently constitute the term ‘CSF’. This research draws on interview data from 22 CSFs to highlight the diversity within the CSF movement and inform ongoing debates about appropriate paths for their continued growth. Interview data is used to describe key areas of convergence and divergence among the goals, business practices, and structures of CSFs. Three general types of CSF are identified based on this analysis: harvester focused, consumer focused and species focused. Each type is described through a short illustrative case study. Overall results indicate that the term ‘CSF’ does not currently refer to a specific structure or type of organization, but rather an approach to seafood marketing used by a variety of organizations with broadly similar production philosophies centered on engaging and informing consumers around traceable, domestically sourced seafood. Acknowledgment of CSFs as diverse and socially embedded organizations is necessary to understanding their potential benefits.
