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.

鱼菜共生系统（Aquaponic systems）在巴西愈发受到重视，吸引了水产养殖、农业、生态学等多个相关领域研究者的关注。本研究通过梳理巴西境内发表的相关文献，旨在评估该国鱼菜共生研究的整体发展现状，重点围绕研究路径、核心作者与研究机构展开分析。研究人员对Scopus、巴西科学电子图书馆（SciELO Brasil）、Web of Science及Google Scholar四大数据库中2008至2022年收录的148篇文献进行了系统综述，结果显示，顶尖研究者与核心研究机构多集中于巴西东南部与南部地区，且大多隶属于已形成成熟体系的水产养殖研究团队。当前研究的核心议题涵盖鱼菜共生系统的运行调控、植物与水生生物物种的筛选等方向。营养液膜技术（Nutrient Film Technique）是被引频次最高的水培系统，罗非鱼与生菜在该系统中展现出最优的生产性能与经济价值。本研究指出，巴西亟需开展针对商业化规模鱼菜共生系统的生物经济研究，以及消费者对鱼菜共生产品的认知态度调研。当前研究仍存在若干短板，主要涉及实验设计与项目管理层面，学界呼吁统一关键实验参数的标准化规范。未来研究可聚焦鱼菜共生研究领域的共现网络与知识结构，以更清晰地把握该领域的发展脉络，推动其与可持续发展实践的深度融合。
