Because of remoteness and a lack of resources, small island developing states (SIDS) are often considered more vulnerable than others to external shocks such as weatherization or disease. In 2020, the Republic of Seychelles has suffered a 70% collapse of foreign visitors, while tourism represents a key pillar of the economy with two thirds of its Gross Domestic Product and employment. The fishery-related industries have nonetheless resisted to this economic shock and become more prominent, with a foreign-owned tuna fleet supplying the local canning plant, main provider of private jobs and trade in the archipelago. This research attempts to forecast the economic effects of several scenarios affecting both fishing and tourism activities in a small island economy. It shows that fish-related industries can represent a resilient contributor to the domestic economy as long as natural stocks are sustainably managed. specialized COVID-19 Social Accounting Matrix scenarios Small Island Developing States Seychelles SEYCHELLES 040 36 24 [12 ] 2023 0990-7440 https://www.documentation.ird.fr/hor/fdi:010090029 10.1051/alr/2023020 0990-7440 [F B010090029] https://www.documentation.ird.fr/hor/fdi:010090029 https://horizon.documentation.ird.fr/exl-doc/pleins_textes/2023-09/010090029.pdf IRD - Base Horizon / Pleins textes 2023-09-22 2026-06-12 fdi:010090029 fre
