Here we propose a framework and agenda for nutrition-sensitive governance (NSG) of fisheries that rethink dominant paradigms of fisheries governance and propose measures to incorporate nutrition-related objectives into fisheries governance. Fish, rich in micronutrients, have potential for improving the nutritional status of coastal and riparian communities, particularly in the Global South where inadequate nutrition is prevalent. Yet, the potential for fish to alleviate malnutrition remains limited to policy documents and high-level government commitments. We propose an agenda for NSG in the Global South grounded in three main pillars: 1-extending the boundaries of fisheries governance, 2-integrating multiple forms of knowledge, and 3-prioritizing domestic and local needs; each of these pillars links different levels of governance starting at the level of conceptualization and images connected to what fisheries are and should do, to a more policy-oriented level with hands-on recommendations, through an intermediate level that links the two. Overall, we propose a concept and agenda for NSG grounded in a human-centred approach to fisheries governance with social sciences playing a crucial role in unearthing the nodes of power that limit access and agency of poor and vulnerable (fishing) communities to the nutritional benefits of fish. In doing so, we critically analyze dominant fisheries governance agendas (‘Blue Economy’, ‘Blue Growth’) through the lens of food and nutrition security and anchor these debates to the objective of getting the right nutrients to those who need them most
