Background

Seafood mislabeling has been increasingly documented over the past decade, raising public concern over the authenticity, safety, and sustainability of seafood products. Tackling seafood mislabeling often poses significant challenges, since it manifests in diverse forms, including misidentifying species, misrepresenting farming versus wild sourcing, and falsifying geographical origins. Economic gain or cultural preferences are often considered the greatest motivations for this fraudulent behavior. However, substitute products are, on average, of equal or lesser conservation concern than the expected products they replace, and the mislabeling of threatened fish species further exacerbates the problem. In particular, the defrauder benefits from selling species that are often poorly managed and wild-caught. Furthermore, seafood mislabeling has the potential to undermine the purchasing behavior of consumers who actively support sustainable fisheries, thus potentially jeopardizing these efforts. Ensuring seafood authenticity is crucial in preventing such practices and fostering sustainable fishing practices that safeguard marine biodiversity. Over the years, diverse analytical techniques and pillars of quality assurance with their unique advantages have been developed to ensure seafood authenticity. Applications of several analytical techniques such as DNA-based techniques, spectrometric techniques, chromatographic techniques, lateral flow immunoassays, and techniques for elemental analysis and stable isotopes have been widely discussed. Nevertheless, continuous exploration of analysis technology rooted in seafood characteristics serves as a theoretical foundation for the entirety of the regulatory process. Given the intricate nature of seafood mislabeling issues, analytical methods require constant updating and refinement, with utmost consideration for result accuracy and timeliness. Consequently, the development of rapid analysis technologies is imperative for enhancing the current state of affairs in the realm of seafood authenticity.

This research topic aims to gather and integrate advancements in rapid analytical techniques for seafood authentication. By disseminating these innovations to industrial risk-management systems, legislators, scholars, and other potential readers, we can enhance the progress toward developing precise and effective analytical methods that safeguard seafood quality and prevent seafood fraud. Specific questions to be addressed include the efficacy of various analytical methods, the development of new technologies, and the integration of these methods into regulatory frameworks. Hypotheses to be tested may involve the accuracy, speed, and cost-effectiveness of novel analytical techniques compared to traditional methods.

To gather further insights into the boundaries of seafood authentication, we welcome articles addressing, but not limited to, the following themes:
- Isothermal amplification methods leveraged for onsite seafood authentication
- Electrochemical and optical DNA-based biosensors focused on seafood authentication
- Mid-infrared (MIR), near-infrared (NIR), and Raman spectroscopy and nuclear magnetic resonance (NMR) techniques for seafood authentication
- Other related novel analytic methods and techniques for seafood authentication.

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.

  • A team of guest editors (called topic editors) lead their Research Topic. This editorial team oversees the entire process, from the initial topic proposal to calls for participation, the peer review, and final publications.

    The team may also include topic coordinators, who help the topic editors send calls for participation, liaise with topic editors on abstracts, and support contributing authors. In some cases, they can also be assigned as reviewers.

  • As a topic editor (TE), you will take the lead on all editorial decisions for the Research Topic, starting with defining its scope. This allows you to curate research around a topic that interests you, bring together different perspectives from leading researchers across different fields and shape the future of your field. 

    You will choose your team of co-editors, curate a list of potential authors, send calls for participation and oversee the peer review process, accepting or recommending rejection for each manuscript submitted.

  • As a topic editor, you're supported at every stage by our in-house team. You will be assigned a single point of contact to help you on both editorial and technical matters. Your topic is managed through our user-friendly online platform, and the peer review process is supported by our industry-first AI review assistant (AIRA).
