The increasing global demand for food, coupled with the impacts of climate change and environmental degradation, has shifted attention towards blue food systems. While these systems offer a potential solution to food security challenges, their sustainability is threatened by various factors, including overfishing, habitat destruction, and climate change. Recognising these challenges, the Food and Agriculture Organisation of the United Nations (FAO, UN) advocates for ensuring the sustainable contribution of aquatic food systems to global food security and nutrition, aligning with the United Nation’s Sustainable Development Goals (UN-SDGs). It was hypothesised that adoption of UN-SDGs would increase the interest of researchers in sustainability of fisheries and aquaculture. Therefore, a bibliometric analysis of the relevant literature published between 2000 and 2023 was conducted to test this hypothesis. The analysis revealed a significant rise in publications addressing climate change and sustainability after the adoption of the UN-SDGs. The countries exhibiting high vulnerability to climate change contributed disproportionately fewer publications to the database. The United States emerged as the leading contributor in terms of publication volume, while Canada’s University of British Columbia was identified as the institution with the highest number of contributing authors. The findings underscore pronounced geographical disparities in research output, with a predominance of countries from the Global North. The underlying factors contributing to these disparities are discussed. Furthermore, the study discusses the policy implications of these findings and emphasises the imperative to prioritise equitable research initiatives. Such efforts are essential to effectively support the realisation of the SDGs within the domain of blue food systems and sustainability.
