The escalating impact of climate change on aquaculture necessitates innovative approaches for maintaining sustainable fish production. This presentation outlines recent strides in fish nutrition aimed at fortifying aquaculture practices in the face of evolving climatic conditions. Novel feed ingredients and formulations are being developed to enhance fish resilience and growth. These ingredients encompass alternative protein and lipid sources, bioactive compounds and probiotics shown to bolster immunity and stress adaptation. Globally, there is a greater focus on the integration of byproducts and sustainable feedstocks, which not only curtails resource depletion but also contributes to the economic viability of regional aquaculture production. This latter piece is critical for the development of aquaculture in areas where lack of quality feeds constrains stronger aquaculture growth. Climate change will only add to the availability challenges for common ingredients and formulated feeds. Solutions need to be regionally focused, and the toolbox of ingredients must be expanded and paired with novel functional feed additives, better production practices and improved fish genetics. Globally, progress in fish nutrition underscores the potential for sustainable aquaculture amid shifting climates. In conclusion, the advancement of sustainable solutions to fish feeds and feeding is vital to navigate the climate challenges constraining aquaculture but especially in areas where aquaculture development lags behind other regions.
