The purpose of the feasibility study was to analyze the current status of the aquaculture sector (production and productivity); assess markets linkages for Timorese aquaculture products; and, examine the potential for domestic feed production. Strengths, Weaknesses, Opportunities and Threats analysis was used for each aquaculture type (mariculture and marine fisheries, freshwater aquaculture and brackish water aquaculture) to identify fish products most suitable for further development in Timor-Leste. Suitability criteria emphasized communitybased aquaculture products that can contribute most to food security and nutrition amongst rural communities.
