Section Policies

Peer Review Process

All manuscripts received by JURNAL PERIKANAN UNIVERSITAS GADJAH MADA (JPUGM; English: International Journal of Aquatic and Fisheries Sciences) will be peer-reviewed by at least two reviewers via Open Journal System (OJS) based on the originality, contribution to the field of the scientific area, coherence of the analysis, grammar, and style. This journal uses a double-blind peer-review policy, which means that both the reviewer and author identities are concealed from each other throughout the review process. The final decision on the acceptability, or otherwise, of manuscripts will be made by the editor-in-chief based on reviewers' comments presented during an editorial board meeting. Scanning for instances of plagiarism in manuscripts will be conducted using Turnitin software. In each manuscript, the peer reviewers will be rated on the substantial and technical aspects. Peer reviewers who collaborate with JPUGM are experts in aquatic and fisheries science.

The editor or the editorial board considers the feedback from the peer reviewers and reaches a decision. The following are the most common decisions:

• accept without any changes (acceptance): the journal will publish the paper in its original form
• accept with minor revisions (acceptance): the journal will publish the paper and asks the author to make small corrections
• accept after major revisions (conditional acceptance): the journal will publish the paper provided the authors make the changes suggested by the reviewers and/or editors
• revise and resubmit (conditional rejection): the journal is willing to reconsider the paper in another round of decision-making after the authors make major changes
• reject the paper (outright rejection): the journal will not publish the paper or reconsider it even if the authors make major revisions

The reviewer's decision will be considered by the Board of Editors to determine the next steps for the manuscript.

• Revision Stage. Once the manuscript has been received with minor or major revision notations, it will be returned to the author along with a review summary form. For manuscripts accepted with major revisions, authors are allotted 3-6 weeks to revise. Whereas for manuscripts accepted with minor revisions, 1 week is allotted for revision. When returning the revised manuscript, the author is required to fill in and attach the cover letter and author's declaration.
• Final decision. At this stage, the manuscript will be re-evaluated by the Board of Editors to ensure that the author has revised in response to the reviewers' concerns. In this final decision, the manuscript may still be rejected if the author did not seriously conduct the necessary revisions.
• Proofread. Upon approval by the Editorial Board, the paper will enter a proofreading phase to ensure linguistic quality.
• Publication confirmation. At this stage, the final layout of the manuscript will be sent to the author again to ensure the content aligns with the author’s writing style. At this stage, the author may revise any typographical errors found in the final manuscript. Once confirmation from the author is received, the editor will process the manuscript for online publication on the website and for print publication. The author(s) will receive the final version of the manuscript as a PDF file. PROOF of all manuscripts will be provided to the corresponding author. The PROOF should be read carefully, checked against the typed manuscript, and returned within 7 days with any corrections. 

• Rejection confirmation. If the manuscript is rejected, the author will be notified by the chief editor with a statement of reasons for rejection. The author may appeal to the chief editor if he or she believes an unfair judgment has been made, which includes the author's reasons. The chief editor will review and discuss the reasons with the section editors responsible for the manuscript and later decide whether to accept or deny the appeal.
• Copyright of manuscripts. Authors submitting manuscripts should understand and agree that copyright of manuscripts of the article shall be assigned/transferred to JURNAL PERIKANAN UNIVERSITAS GADJAH MADA (JPUGM) Journal. The statement to release the copyright to JURNAL PERIKANAN UNIVERSITAS GADJAH MADA (JPUGM) Journal is stated in the author’s declaration form. This work is licensed under a Creative Commons Attribution-ShareAlike 4.0 International License (CC BY-SA), where authors and readers can copy and redistribute the material in any medium or format, as well as remix, transform, and build upon the material for any purpose, but they must give appropriate credit (cite to the article or content), provide a link to the license, and indicate if changes were made.

JOB DESCRIPTION OF PUBLICATION PROCEDURE IN JPUGM:

ROUTE 1

• Checking if there is any manuscript submission on the website
• If there is available, download the original file and supplement files (usually consisting of cover page & declaration page)
• The original file is forwarded to the admin secretary for plagiarism check through the Turnitin application. If the author does not include the supplement files, they must be requested from the author via email (a request email is sent along with pre-review in route 2. Note: Author declaration is not compulsory. Meanwhile, if the author has already included the supplement files, they need to forward them to the journal admin for archiving.

ROUTE 2

• Assessing the manuscript's content quality in accordance with the JPUGM author guidelines, including the title, aims and scope, state of the art, novelty or research gap, the content's impact on the scientific community, and supplementary information such as author contributions, conflicts of interest, acknowledgments, and funding sources.
• Assessment of the manuscript's plagiarism rate by the administrative secretary and the appointment of the SECTION EDITOR.
• Implementing a checklist for pre-review to ascertain the manuscript's compliance with the JIPK author guidelines template.
• Return the pre-review to the author for revision, including a request for the cover page (if absent) as well as tables and figures in HD-quality jpg/jpeg format for layout purposes. The deadline for pre-review revisions is 3 to 4 days, contingent upon whether the revisions are modest or extensive. Reminder: If the due date has passed, notify the author daily.
• If the author submits a revision, the editorial team determines whether to accept, reject, or request further revisions of the manuscript prior to forwarding it to the reviewers.

ROUTE 3

• The section editor seeks the reviewers. The SECTION EDITOR typically possesses a designated reviewer; nevertheless, if the SECTION EDITOR encounters difficulty in selecting reviewers, assistance can be obtained by consulting the reviewer recommendations provided by the author on the cover page.
• Reviewers must comprise at least two independent individuals, one of whom is from Asia and the other a foreign national, or all reviewers may be foreign nationals.
• The review process is completed within a maximum of 7 to 21 days. Reminder is done in D-3 and D-10.
• Monitoring the email flow between the SECTION EDITOR and reviewers to help remind the reviewers if the SECTION EDITOR forgets or has another business
• After the review process is done, the section editor sends the manuscript back to the author for revision (make sure to wait until 2 reviewers are done reviewing). The deadline for the author to revise the manuscript is 10 days.
• Make sure the reviewers have already completed the review form from SECTION EDITOR, since this form will be used to submit the data on the website and to list the reviewers for the archive.
• After the manuscript is revised by the author, the SECTION EDITOR sends it back to the reviewers to check if it has been revised accordingly.

ROUTE 4

• SECTION EDITOR forwards the manuscript to the editor to decide, through an internal meeting by the editorial team of JPUGM, and based on the consideration from reviewers, whether it is worth being published, needs further revision, or is fully rejected
• If the manuscript needs to be revised again, the due date is 5 days at maximum.

ROUTE 5

• The accepted manuscript is final edited by the copyeditor
• The manuscript is proofread by professional proofreader(s) then sent back to the author for revision
• After that, the manuscript goes through the layout process based on the JPUGM publication standard, galley changes to a PDF file, and links the references in the PDF.

ROUTE 6

• Final checking is done by the author and the JPUGM staff to double-check the manuscript before it is published.

ROUTE 7

• If the manuscript does not need a revision, it will be grouped into three types of publication under the category of Issue in Press. All accepted manuscripts/articles are pre-published temporarily in "Article In Press of JPUGM Journal” and are not assigned to a volume/issue number yet. That means all articles in this pre-issue are awaiting formal publication in the next issue. Please note that the DOI for this in-press issue has not yet been registered. This issue is still in progress for publishing and has not yet been officially published. So, the articles will be finished, and the issue will be published (the published manuscript corresponds to the volume and issue).

All review processes are double-blind peer review and are managed by the editor in the Open Journal Systems (OJS).

Publication Ethics and Malpractice Statement

JPUGM Statement

All submitted manuscripts must comply with the established policies of the Jurnal Perikanan Universitas Gadjah Mada (JPUGM). We are committed to upholding the highest standards of publication ethics, strictly adhering to the principles outlined by the Committee on Publication Ethics (COPE) in its core practices. Our editorial process ensures rigorous oversight in addressing critical issues, including conflicts of interest, authorship and contributorship disputes, allegations of misconduct, data integrity, plagiarism, and the transparency of the peer-review process.

Ethical standards are implemented to safeguard the quality of scientific publications, foster public confidence in research findings, and ensure appropriate recognition of intellectual contributions. The JPUGM Editorial Board maintains full autonomy, ensuring that editorial decisions are made independently of the publisher’s influence. Nonetheless, the journal reserves the right to revoke the acceptance of any manuscript should ethical or legal concerns emerge. Any work found to be in violation of JPUGM’s ethical mandates is subject to retraction. To ensure compliance with these guidelines, every submission undergoes a rigorous screening process involving automated tools, such as Turnitin, alongside manual evaluations by the Editorial Office. In cases where discrepancies are identified, a thorough human verification is conducted, frequently involving consultation with an Academic Editor to determine the appropriate course of action.

Publication Ethics Statement

JPUGM upholds a rigorous peer-review process complemented by transparent ethical policies to facilitate the contribution of high-quality scientific research to the global scholarly community. We are committed to investigating any identified ethical concerns and taking the necessary measures to safeguard the integrity of the academic record. Furthermore, we prioritize the protection and safety of research participants, ensuring that all published studies adhere to established ethical safety standards.

All submitted manuscripts must strictly adhere to the editorial and ethical policies of JPUGM, as detailed on this page and within the JPUGM Instructions for Authors. Furthermore, authors are expected to ensure that their submissions comply with the specific guidelines and technical requirements established by the journal to maintain consistency and scholarly excellence.

Author Responsibilities and Ethics

Ethical Guidelines for Authors

Authors submitting their work to JPUGM must guarantee that their manuscripts are ethically sound and strictly adhere to industry-recognized standards as reflected in the journal's official policies. It is the responsibility of the authors to ensure that every aspect of their research conduct and reporting aligns with these established ethical benchmarks before submission.

Authors must strictly refrain from any misrepresentation of research findings, as such practices jeopardize the credibility of the journal, undermine the professionalism of scientific authorship, and ultimately compromise the integrity of the entire scientific endeavor. JPUGM emphasizes that the honest reporting of data is fundamental to the advancement of knowledge and the maintenance of public trust in scholarly research. Author who submit their manuscript to JPUGM must:

• Accurately present their research findings and include an objective discussion of the significance of their findings.
• Uphold accurate authorship, by including all and only those who qualify for authorship and clearly stating their contribution.
• Authors should be familiar with and adhere to best practices in publication ethics, especially concerning authorship such as avoidance of ghost or guest authorship, dual submission, attribution, plagiarism, image integrity and figure preparation, and competing interests. 
• Authors must also comply with JPUGM policies on research ethics (Fish subjects research, animal research, global research).
• Disclose any facts that might be perceived as a possible conflict of interest at submission.
• Present their data and methods with attention to detail. Data and methods used in the research need to be presented in sufficient detail in the manuscript so that other researchers can replicate their work. Raw data must be made publicly available unless there is a compelling reason otherwise (e.g., project confidentiality).
• A single study should not be split up into several parts to increase the quantity of submissions and submitted to various publications or to one publication over time (i.e. ‘salami-slicing/publishing'). 
• The manuscript should not be submitted to more than one publication for simultaneous consideration. The submitted work should be original and should not have been published elsewhere in any form or language (partially or in full), unless the new work concerns an expansion of previous work. (Please provide transparency on the re-use of material to avoid the concerns about text-recycling (‘self-plagiarism').
• Concurrent or secondary publication is sometimes justifiable, provided certain conditions are met. Examples include: translations or a manuscript that is intended for a different group of readers.
• Results should be presented clearly, honestly, and without fabrication, falsification or inappropriate data manipulation (including image based manipulation).
• Authors should adhere to discipline-specific rules for acquiring, selecting and processing data. No data, text, or theories by others are presented as if they were the author's own (‘plagiarism').
• Proper acknowledgements to other works must be given (this includes material that is closely copied (near verbatim), summarized and/or paraphrased), quotation marks (to indicate words taken from another source) are used for verbatim copying of material, and permissions secured for material that is copyrighted.
• Original research results must be novel and not previously published, and any translations must abide by our policy on translations.
• Obtain permission to publish from the copyright holder for any previously published content (including quotations, figures or tables).
• Communicate errors and inaccuracies found after publication promptly.
• Authors should make sure they have permissions for the use of software, questionnaires/(web) surveys and scales in their studies (if appropriate).
• Research articles and non-research articles (e.g. Review articles) must cite appropriate and relevant literature in support of the claims made.
• Excessive and inappropriate self-citation or coordinated efforts among several authors to collectively self-cite is strongly discouraged.
• Authors should avoid untrue statements about an entity (who can be an individual person or a company) or descriptions of their behaviour or actions that could potentially be seen as personal attacks or allegations about that person. 
• Research that may be misapplied to pose a threat to public health or national security should be clearly identified in the manuscript (e.g. dual use of research). Examples include creation of harmful consequences of biological agents or toxins, disruption of immunity of vaccines, unusual hazards in the use of chemicals, weaponization of research/technology (amongst others).
• Authors are strongly advised to ensure the author group, the Corresponding Author, and the order of authors are all correct at submission. Adding and/or deleting authors during the revision stages is generally not permitted, but in some cases may be warranted. Reasons for changes in authorship should be explained in detail. Please note that changes to authorship cannot be made after acceptance of a manuscript. [See also Authorship principles]

In the event of suspected research misconduct or alleged fraud, JPUGM and the publisher will initiate a formal investigation in strict accordance with the COPE guidelines. Should the investigation yield valid concerns, the editorial office will contact the respective author(s) via their registered email addresses to provide them with a fair opportunity to respond and address the allegations. This process is conducted to ensure due process and maintain the highest standards of scientific accountability.

If ethical concerns arise while a manuscript is still under consideration, JPUGM reserves the right to reject the submission and return it to the authors. For articles that have already been published online, the journal will take appropriate action based on the severity of the infraction. Such measures may include:

• The issuance of an Erratum or Correction to be appended to the article;
• The publication of an Editorial Expression of Concern;
• In cases of severe misconduct, the formal Retraction of the article.

All actions are taken to ensure the transparency and reliability of the published scientific record.

The specific rationale for any such action will be clearly stated within the published Erratum/Correction, Editorial Expression of Concern, or Retraction Note. It is important to note that a Retraction does not involve the removal of the article from the journal’s digital platform. Instead, the original article will be maintained and prominently watermarked as 'RETRACTED.' A formal explanation detailing the reasons for the retraction will be provided in a linked note to ensure full transparency and to maintain the integrity of the scholarly archive.

In cases of confirmed misconduct, the JPUGM Editorial Office reserves the right to notify the author's home institution. Furthermore, a formal notice regarding the violation of ethical standards within the peer-review process may be permanently incorporated into the bibliographic record of both the author and the specific article to ensure long-term accountability within the scientific community.
