The objective of this study is to synthesize existing literature on climate adaptation practices (CAPs) in the aquaculture sectors of Bangladesh, Kenya, and Zambia, and to inform the development of an Adaptation Decision Support System for Aquaculture (ADSS 4 Aqua). The qualitative review provides a consolidated understanding of emerging and context-specific adaptation options and proposes a strategic framework to support evidence-based, climate-resilient aquaculture development. The findings are intended to guide policymakers and development partners in designing pilot interventions, formulating responsive policies, and prioritizing future investments in climate adaptation within the aquaculture sector.
