Models which can accurately forecast future responses of climate sensitive ecosystems and their dependent biota are vital for the definition and fashioning of sustainable management practices that favor species conservation and support their resilience to multiple stressors, including global warming. The development of the Lakes and Water Sectors within ISIMIP makes it now possible to examine the controls of freshwater fish production and survival within a holistic inter-sectoral framework, and provide open source workflows and tools to aid management. This project will aim to expand the range of geographically explicit models available through ISIMIP to include growth, phenology, distribution and, ultimately, production of freshwater fish, specifically focusing of diadromous Atlantic salmon across its native range.
