Sea surface temperature (SST) has increased approximately 1°C since 1901 and is projected to intensify in the future. Unlike wild species that can migrate to more suitable locations as oceans warm, captive species require proactive management and infrastructure relocation to cope with climatic shifts. Climate analogues offer valuable insights about where future conditions will match current climates, providing crucial information for aquaculture planning and adaptation. This study identified climate analogues for Salmo salar (Atlantic salmon) production in Tasmania, Australia for the period 2021-2100 by combining Earth System Model ensembles with current thermal conditions in productive areas and multiple ocean uses. Our findings reveal that suitable areas for Atlantic salmon aquaculture are projected to decline across decades, with severe losses occurring beyond 2061 and intensifying under higher warming scenarios. This decline is particularly pronounced in near-coast environments and along the east and north coasts. Despite that, future available area exceeds current production areas, though successful utilization would require offshore capabilities. These projections of climate-driven changes in aquaculture areas can guide decision-making about the environmental and economic longevity of current sites and cultivated species, and may catalyse policies supporting offshore aquaculture development, fish thermal tolerance, and aquaculture infrastructure technological advancements.
