During late 2019 and early 2020, MCD Vietnam conducted a value chain analysis (VCA) focused on fishery supply chains in Binh Dinh Province, Vietnam for three tuna species: bigeye tuna (Thunnus albacares), yellowfin tuna (Thunnus obesus) and skipjack tuna (Katsuwonus pelamis). This report summarizes the results of the Tuna VCA completed, including identification of the flow of products, types of products, relationships and linkages among actors in the chain, relevant institutional policies and regulations, abilities to apply electronic catch documentation and traceability (eCDT) technologies in the tuna chain, as well as evaluating the value chain linkages.  The VCA was led by MCD as part of an eCDT learning site in Vietnam in partnership with the USAID Oceans project.  The Binh Dinh VCA study was divided into two analyses of yellowfin/bigeye and skipjack. Both VCAs include analysis of multiple fishery supply chain actors including: fishers, middle-actors, transporters, processing and export companies, international trading companies, wholesalers/retailers and consumers.  This report was produced by MCD under a partnership subcontract with USAID Oceans, with support from USAID RDMA.
