Status of aquaponics systems in Brazil: a systematic literate review - APPENDIX S1

Aquaponic systems have gained prominence in Brazil, attracting researchers from aquaculture, agriculture, ecology, and other similar fields. This study reviewed Brazilian publications to assess the national status of aquaponics, focusing on research approaches, key authors, and institutions. A systematic review of 148 works (2008–2022) from Scopus, SciELO Brasil, Web of Science, and Google Scholar revealed that most prominent researchers and institutions are concentrated in the Southeast and South, primarily in established aquaculture research groups. Key topics include operation of aquaponic systems and selection of species of plants and aquatic organisms. The nutrient film technique was the most cited hydroponic system, with tilapia and lettuce showing the best performance and economic value. The study highlights the need for further research on the bioeconomic of commercial-scale aquaponics and consumer perceptions of aquaponic products in Brazil. Identified gaps include experimental design and project management, with a call for standardization of key experimental parameters. Future investigations should explore the co-occurrence network and intellectual structure of aquaponics research to better understand its development and integration into sustainable practices.
