This technical paper focuses primarily on price transmissions in small-scale and large-scale fishery and aquaculture value chains in 14 developed and developing countries. Although the study is focused on the small-scale sector, both the small-scale and large-scale sectors were analysed in order to demonstrate differences between the two. The document begins with an overview of the entire project and its global implications, reviewing the importance of fisheries and aquaculture to livelihoods, food security and trade as well as the rationale for value chain analysis. It then presents detailed and summarized country-specific information on the research and analysis conducted, presenting analysis methodology, findings and policy recommendations within each country. An additional section focuses on women, summarizing their significant role in fishery and aquaculture value chains in selected countries. Finally, the document outlines the general findings and policy recommendations that emerged as key themes across all value chains analysed.
