Climate change is placing aquaculture and culture-based fisheries under increasing stress, threatening global food security and the livelihoods of millions. Rising temperatures, unpredictable floods and droughts, ocean acidification, and shifts in salinity are disrupting fish growth, survival, and productivity. This article reviews the major environmental stressors affecting freshwater, brackish water, coastal, inland saline, cold-water, ornamental, and culture-based fisheries, and highlights climate-resilient adaptations now in practice. Approaches such as integrated multi-trophic aquaculture, recirculating aquaculture systems, selective breeding, species diversification, and habitat-based protection measures can help maintain production despite adverse conditions. The discussion highlights how innovative technologies, nature-based solutions, and enhanced management strategies can mitigate the impacts of climate change while supporting local economies. Building resilience in aquaculture is essential to ensuring a stable and sustainable fish supply for the future.
