Background

Aquaponics is defined as the synergistic integration of recirculating aquaculture and hydroponics, and is increasingly recognized as a closed-loop agro-technological solution that aligns with the principles of a circular bioeconomy. This innovative system utilizes microbial-mediated nutrient transformations to convert aquaculture effluents, characterized by high levels of ammonia and organic matter, into bioavailable nutrients for plant uptake. This process facilitates the reuse of water, the valorization of waste, and the simultaneous production of biomass from both aquatic and terrestrial sources. Consequently, aquaponics significantly mitigates environmental loading and reduces dependency on external inputs. However, persistent knowledge gaps regarding system optimization, regulation of water chemistry, nutrient stoichiometry, and the scalability of integrated digital control frameworks pose significant barriers to the widespread adoption of this technology. This Research Topic (RT) aims to bring together interdisciplinary scientific advances focused on emerging technological, biological, and digital innovations in aquaponics.

The goal of this RT is to investigate how aquaponics can be effectively leveraged to enhance sustainability in aquaculture by integrating circular resource flows, digital technologies, and adaptive designs. Aquaponics has the potential to convert aquaculture waste streams into nutrient-rich inputs for plant growth, thereby reducing environmental impacts and closing biogeochemical loops.

This topic focuses on both the theoretical and applied dimensions of aquaponics as a component of circular aquaculture systems. It will bring attention to emerging tools, such as IoT-based sensing, automation, and data analytics, that can optimize water quality, nutrient flow, and system resilience. It also aims to explore the use of brackish water and treated effluent in aquaponics to expand applicability in arid and semi-arid regions. Ultimately, this RT will consolidate current knowledge and inspire innovations that position aquaponics at the intersection of aquaculture, food security, water reuse, and digital agriculture.

Some key questions:

-How can decoupled aquaponic systems improve nutrient efficiency and water management for diverse fish and crop species?

-What is the role of IoT and sensor-based control in improving real-time system performance and early warning diagnostics?

-How can aquaponics be adapted for arid regions and climate-stressed environments using brackish water and off-grid energy?

We welcome the following manuscripts: Brief Research Report, Case Report, Editorial, General Commentary, Mini Review, Original Research, Perspective, Review, Systematic Review, Technology and Code that address key scientific and technological aspects of aquaponics in the context of sustainable aquaculture.

Topics of interest include:

• Freshwater, brackish, coupled, and decoupled aquaponic systems

• Use of aquaculture effluent for nutrient recovery and wastewater treatment

• Sensor-based monitoring, IoT integration, and automated control systems

• Microbial ecology, nitrification dynamics, and nutrient partitioning

• System modeling, life cycle assessment (LCA), and circularity metrics

• Adaptation to arid and saline environments

• Socio-economic assessments and policy frameworks for integrated systems

Authors are encouraged to submit interdisciplinary work that combines aquaculture engineering, plant science, microbiology, digital agriculture, and sustainability assessment. The aim is to provide practical and theoretical insights that contribute to the evolution of aquaponics into a key pillar of circular aquaculture systems.

Topic editors

Frequently asked questions

  • Frontiers' Research Topics are collaborative hubs built around an emerging theme.Defined, managed, and led by renowned researchers, they bring communities together around a shared area of interest to stimulate collaboration and innovation.

    Unlike section journals, which serve established specialty communities, Research Topics are pioneer hubs, responding to the evolving scientific landscape and catering to new communities.

  • The goal of Frontiers' publishing program is to empower research communities to actively steer the course of scientific publishing. Our program was implemented as a three-part unit with fixed field journals, flexible specialty sections, and dynamically emerging Research Topics, connecting communities of different sizes and maturity.

    Research Topics originate from the scientific community. Many of our Research Topics are suggested by existing editorial board members who have identified critical challenges or areas of interest in their field.

  • As an editor, Research Topics will help you build your journal, as well as your community, around emerging, cutting-edge research. As research trailblazers, Research Topics attract high-quality submissions from leading experts all over the world.

    A thriving Research Topic can potentially evolve into a new specialty section if there is sustained interest and a growing community around it.

  • Each Research Topic must be approved by the specialty chief editor, and it falls under the editorial oversight of our editorial boards, supported by our in-house research integrity team. The same standards and rigorous peer review processes apply to articles published as part of a Research Topic as for any other article we publish.

    In 2023, 80% of the Research Topics we published were edited or co-edited by our editorial board members, who are already familiar with their journal's scope, ethos, and publishing model. All other topics are guest edited by leaders in their field, each vetted and formally approved by the specialty chief editor.

  • Publishing your article within a Research Topic with other related articles increases its discoverability and visibility, which can lead to more views, downloads, and citations. Research Topics grow dynamically as more published articles are added, causing frequent revisiting, and further visibility.

    As Research Topics are multidisciplinary, they are cross-listed in several fields and section journals – increasing your reach even more and giving you the chance to expand your network and collaborate with researchers in different fields, all focusing on expanding knowledge around the same important topic.

    Our larger Research Topics are also converted into ebooks and receive social media promotion from our digital marketing team.

  • Frontiers offers multiple article types, but it will depend on the field and section journals in which the Research Topic will be featured. The available article types for a Research Topic will appear in the drop-down menu during the submission process.

  • Yes, we would love to hear your ideas for a topic. Most of our Research Topics are community-led and suggested by researchers in the field. Our in-house editorial team will contact you to talk about your idea and whether you’d like to edit the topic. If you’re an early-stage researcher, we will offer you the opportunity to coordinate your topic, with the support of a senior researcher as the topic editor.
