This report provides a generalised mapping and description of the seafood value chains for the six case studies covered by FarFish. The work is based on publicly available data and has primarily been carried out as desktop analyses. One major challenge in this work has been the lack of reliable data, which in fact is a general challenge for these fisheries. The fisheries are conducted by multi-national fleets and different vessel types, ranging from artisanal fisheries to large scale industrial fisheries; and the reporting from these fleets vary a great deal. The available data from within the value chains from processing to consumption does vary considerably as well.
