Aquaponics, a production system that integrates aquaculture and hydroponics, stands out for its ability to produce food sustainably, promoting the recycling of nutrients, the efficient use of water and generating high quality and safe foods. For this reason, the objective of this review article was to compile the most relevant concepts and advances achieved in the application of this productive technique, through exploration and systematization of research published in indexed journal databases during the decade between 2012 to 2022. Results obtained were organized into four large categories: 1. Aquaponics from a biological perspective; 2. viability and profitability of aquaponic systems; 3. engineering developments, new trends and technologies in aquaponics; and 4. environmental and social aspects of aquaponics. The information presented below will allow to know the potential feasibility and adaptability of aquaponic systems in the context of environmental, social, and economic changes. In this sense, bibliometrics, carried out in 55 selected publications, allows to identify the year 2020 as the highest scientific production in aquaponic systems with 23% of total production in the decade studied and that 63% of research was published in the last 5 years (2018 to 2022). Finally, by thematic area, it was found that 44% of the research carried out corresponds to the "engineering developments, new trends and technologies" category, followed by "biological perspective", and "environmental and social aspects" (28% and 20%, respectively). The area with the lowest quantity of publications corresponded to "viability and profitability" (8% of the total references).

Keywords : aquaponics; nitrification process; economic viability; integrated aquaculture systems.
