Aquaponics is an approach of coupling two technologies: recirculation aquaculture (fish-farms) and hydroponics (soil-less cultivation of crops). While it is perceived as a way to contribute to more sustainable food systems, the technology is still in its infancy, with several challenges. This paper describes current conditions of development and identifies aspects that can promote or hinder future pathways. We focus our analysis on the EU, using Germany as an institutional case study, while also considering worldwide developments. We propose a framework to analyze aquaponics as an emerging technological innovation system at the interface between existing fish and plant production systems. The approach is explorative based on a literature review and interviews with experts. The main findings are that stakeholders have different views regarding the future development pathways, knowledge to manage complex systems in the long term is needed and it is still unclear how to design institutional conditions to deliver sustainable outcomes. •We analyze aquaponics as an emerging technological innovation system (TIS) for sustainable food production.•We identify directions and key functions currently underdeveloped.•Divergent visions, knowledge, complexity and need for reflexive sustainability governynce are key findings.
