Pacific Island countries have an extraordinary dependence on fisheries and aquaculture. Maintaining the benefits from the sector is a difficult task, now made more complex by climate change. Here we report how changes to the atmosphere-ocean are likely to affect the food webs, habitats and stocks underpinning fisheries and aquaculture across the region. We found winners and losers-tuna are expected to be more abundant in the east and freshwater aquaculture and fisheries are likely to be more productive. Conversely, coral reef fisheries could decrease by 20% by 2050 and coastal aquaculture may be less efficient. We demonstrate how the economic and social implications can be addressed within the sector-tuna and freshwater aquaculture can help support growing populations as coral reefs, coastal fisheries and mariculture decline.

Global habitat preferences of commercially valuable tuna (2015, background): “Habitat models can be used to predict future impacts of anthropogenic climate change on tuna distribution and abundance (Hobday, 2010; Lehodey et al., 2013), allowing to develop alternative management strategies and adapt to future socio economic scenarios (Bell et al., 2013).”

Report card on ecosystem-based fisheries management in tuna regional fisheries management organizations (2018, background): “The identification of habitats of special concern for species is also increasingly becoming an essential task to design effective responses to climate change as well as other marine threats (Bell et al., 2013; Brierley & Kingsford, 2009).”
Small islands, valuable insights: systems of customary resource use and resilience to climate change in the Pacific (2014, background): “Ocean acidification is predicted to inhibit coral reef growth, which will result in habitat loss (Keener et al. 2012) and up to 20% decline in coastal fisheries by 2050 (Bell et al. 2013).”
