This article examines aquaponic systems, which represent an innovative agriculture method that combines aquaculture and hydroponic techniques with the purpose of growing vegetables, fish, and microorganisms. Also called "aquaponics", these systems are an environmentally friendly alternative to traditional agriculture, because they require less land, less water, close to no fertilizers and/or pesticides to ensure food production and food safety. The current review of 25 studies from the scientific literature aims to contribute to the understanding of recent innovations in aquaponic systems by providing a comprehensive analysis thereof. The goal is to help identify the best practices, challenges, and potential improvements in aquaponics. The analysis reveals that recent innovations in aquaponics encompass a multitude of aspects, including system design, operation, and the optimization of plant and fish growth. These innovations have expanded the feasibility of aquaponics, making it increasingly adaptable to diverse environmental conditions and production goals. The degree of novelty observed in recent aquaponic innovations underscores the dynamic nature of this field, with numerous ongoing efforts to address emerging challenges and opportunities. We conclude that the reviewed studies offer a valuable repository of knowledge, offering the potential to shape future research, guide practical applications, and influence policy decisions aimed at harnessing the full potential of aquaponic systems on a global scale.
