Indexing and Abstracting

The journal is committed to upholding the highest standards of publication ethics and pays regard to Principles of Transparency and Best Practice in Scholarly Publishing published by <a href="https://publicationethics.org/" target="_blank" style="background-color: transparent;">the Committee on Publication Ethics (COPE)</a>, <a href="https://doaj.org/apply/transparency/#principles-of-transparency-and-best-practice-in-scholarly-publishing" target="_blank" style="background-color: transparent;">the Directory of Open Access Journals (DOAJ)</a>, <a href="https://oaspa.org/" target="_blank" style="background-color: transparent;">the Open Access Scholarly Publishers Association (OASPA)</a>, and <a href="https://www.wame.org/" target="_blank" style="background-color: transparent;">the World Association of Medical Editors (WAME)</a> on <a href="https://publicationethics.org/resources/guidelines-new/principles-transparency-and-best-practice-scholarly-publishing" target="_blank" style="background-color: transparent;">https://publicationethics.org/resources/guidelines-new/principles-transparency-and-best-practice-scholarly-publishing</a>The subjects covered in the manuscripts submitted to the Journal for publication must be in accordance with the aim and scope of the Journal. Only those manuscripts approved by every individual author and that were not published before in or sent to another journal, are accepted for evaluation.Changing the name of an author (omission, addition or order) in papers submitted to the Journal requires written permission of all declared authors.Plagiarism, duplication, fraud authorship/denied authorship, research/data fabrication, salami slicing/salami publication, breaching of copyrights, prevailing conflict of interest are unethical behaviors. All manuscripts not in accordance with the accepted ethical standards will be removed from the publication. This also contains any possible malpractice discovered after the publication.Plagiarism Submitted manuscripts that pass preliminary control are scanned for plagiarism using iThenticate software. If plagiarism/self-plagiarism will be found authors will be informed. Editors may resubmit manuscript for similarity check at any peer-review or production stage if required. High similarity scores may lead to rejection of a manuscript before and even after acceptance. Depending on the type of article and the percentage of similarity score taken from each article, the overall similarity score is generally expected to be less than 15 or 20%.Double Blind Peer-Review After plagiarism check, the eligible ones are evaluated by the editors-in-chief for their originality, methodology, the importance of the subject covered and compliance with the journal scope. The editor provides a fair double-blind peer review of the submitted articles and hands over the papers matching the formal rules to at least two national/international referees for evaluation and gives green light for publication upon modification by the authors in accordance with the referees’ claims.

Editor should consider publishing correction if minor errors that do not effect the results, interpretations and conclusions of the published paper are detected. Editor should consider retraction if major errors and/or misconduction that invalidate results and conclusions are detected.Editor should consider issuing an expression of concern if there is evidence of research or publication misconduct by the authors; there is evidence that the findings are not reliable and institutions of the authors do not investigate the case or the possible investigation seems to be unfair or nonconclusive.The guidelines of <a href="https://publicationethics.org/resources/flowcharts/complete-set-english" target="_blank" style="background-color: transparent;">COPE</a> and <a href="https://www.icmje.org/recommendations/" target="_blank" style="background-color: transparent;">ICJME</a> are taken into consideration regarding correction, retractions or expression of concern.RetractionJournal follows <a href="https://publicationethics.org/sites/default/files/retraction-guidelines-cope.pdf" target="_blank">COPE’s Retraction Guidelines</a> in case of retraction. The editor has the right to retract an article if: <ul><li>There is clear evidence that the findings are unreliable; either as a result of a major error (e.g. miscalculation or experimental error), or as a result of fabrication (e.g. of data) or falsification (e.g. image manipulation).</li><li>It contains plagiarised content. </li><li>It has been published elsewhere without proper attribution. </li><li>It contains material or data without authorisation for use.</li><li>There is copyright infringement or there is some other serious legal issue.</li><li>It reports unethical research. </li><li>There is evidence that the peer-review process is compromised or manipulated.</li><li>The author(s) failed to disclose a significant competing interest (also known as a conflict of interest) that, in the opinion of the editor, would have unduly influenced the interpretation of the work or the recommendations of the editors and peer reviewers.</li></ul>In case of retraction the following steps are followed:<ul><li>Retraction notice including article title is published in a subsequent issue of the journal. The retraction notice is paginated and listed in the table of contents. </li><li>A link is provided between the retraction notice and the original article in the electronic version. </li><li>The online article is preceded by a page containing the retraction notice; the reader can then proceed to the article itself.</li><li>The original article remains unchanged, except for a watermark on the .pdf on each page stating that it has been &#34;retracted”.</li></ul>Article Removal for Legal ReasonsIn the following circumstances, except the metadata (title and authors), the text of the article is removed and a page informing that the article has been removed for legal reasons replaces the article. <ul><li>The article is found to be defamatory or to infringe the legal rights of others, and retraction is not deemed to be an adequate solution.</li><li>The article has been, or is reasonably likely to be the subject of a court order.</li><li>There is a significant risk to public health.</li></ul>

To guarantee that all papers published in the journal are maintained and permanently accessible, articles are stored in Dergipark which serves as a  national archival web site and at the same time permits LOCKSS to  collect, preserve, and serve the content.Additionally, authors are encouraged to self-archive the final PDF version of their articles in open electronic archives with  that conform to standards of Open Archives Initiative (<a href="https://www.openarchives.org/" target="_blank" style="background-color: transparent;">https://www.openarchives.org/</a>). Authors should provide a link from the deposited version to the URL of IUPress journal website.

The Artificial Intelligence Policy, prepared in light of developments in artificial intelligence (AI) and practices in scholarly publishing, sets out the editorial and ethical principles that authors, reviewers, and editors should follow when using such technologies. The following sources have been considered in the preparation of the AI policy:Committee on Publication Ethics <a href="https://publicationethics.org/guidance/cope-position/authorship-and-ai-tools" target="_blank">(COPE) - Authorship and AI tools</a>; International Committee of Medical Journal Editors <a href="https://www.icmje.org/recommendations/browse/roles-and-responsibilities/defining-the-role-of-authors-and-contributors.html#four" target="_blank">(ICMJE) - Artificial Intelligence (AI)-Assisted Technology; World Association of Medical Editors  (WAME) Chatbots, Generative AI, and Scholarly Manuscripts</a><a href="https://www.icmje.org/recommendations/browse/roles-and-responsibilities/defining-the-role-of-authors-and-contributors.html#four"></a>AI-assisted technologies (such as large language models [LLMs], chatbots, or image generators) can develop and produce a wide variety of content, including text, images, audio, and synthetic data. When used ethically and safely, these capabilities can increase productivity and foster innovation, but when used without human guidance, they pose risks such as inaccurate and biased results, omissions and errors in citations, deficiencies in protecting privacy and intellectual property rights, and potential violations of authors' and publishers' rights. IUPress adopts the following core principles to avoid these risks in the use of AI:  <ul><li>Details of any AI used in the production of content (including but not limited to text, figures, images, and code) must be declared and clearly explained in the appropriate section of the paper (as an acknowledgement and/or in the methods section). </li><li>No AI tool may be listed as an author in any scientific paper. </li><li>Authors are responsible for the accuracy, completeness, and originality of their work, even if AI is used in any way; they are responsible for the proper referencing and attribution of others' ideas, data, words, or other materials. </li><li>Reviewers and editors must not upload submitted work, in whole or in part, to any generative AI application.</li></ul>In the editorial processes of IUPress publications, tools are available to assist editors in identifying AI-generated content. On the other hand, it is common to use AI tools that provide suggestions for improving and enhancing readability, language, and grammar, and such AI tools can be used in IUPress publications under the supervision of editors and authors.

Artificial Intelligence Policy

<ul><li>Authors are required to declare if they have used AI-assisted technologies (such as large language models [LLMs], chatbots, or image generators) in the creation of their submitted work. </li><li>Authors should explain, both in the cover letter and in the appropriate section of the submitted paper (as a footnote and/or in the methods section), which AI tool and which version of it they have used and for what purpose. </li><li>Authors should also indicate how they used the AI tool and how they assessed the validity of the results obtained using this technology, and what aspects of the paper, manuscript content, data or supporting files were influenced by the use of the AI tool or were generated by AI.</li><li>It is the authors' responsibility to ensure the accuracy, validity and appropriateness of content and citations generated by AI-assisted technologies and to eliminate potential errors, inconsistencies and biased results. </li><li>Authors should always check the original sources to eliminate possible plagiarism, recognising that there is a potential for plagiarism in texts produced with AI-assisted technologies. They should confirm that they have checked and that the sources are original.  </li><li>AI-assisted tools (such as ChatGPT) cannot be listed as authors because they cannot be responsible for the accuracy, integrity, and originality of the work, and these responsibilities are essential to authorship. Therefore, authors are responsible for all material involving the use of AI-assisted technologies. Authors should ensure that all statements in the article that state the hypotheses, interpretations, conclusions, limitations, and implications of the study represent their own opinions.  </li><li>Studies created by authors using AI tools in the following ways, which substitute for the basic researcher's and author's responsibilities, violate the principles of scientific publishing and publication ethics, and such studies are not eligible for inclusion in publications: </li></ul><ul><ul><li>Generation of text or code without rigorous review, </li><li>Generation of synthetic data to replace missing data without a robust methodology, </li><li>Creation of any inaccurate, synthetic content, including abstracts or supplementary materials, </li><li>Creation and manipulation of images and figures (pictures, graphs, data tables, medical images, image snippets, computer codes and formulae) or original research data (enhancing, hiding, moving, removing or adding a particular feature within an image or figure) using AI.</li></ul></ul>

It is essential to maintain confidentiality in the peer review process and not to share or use the reviewed work in this process. <a href="https://publicationethics.org/sites/default/files/ethical-guidelines-peer-reviewers-cope.pdf" target="_blank">(COPE – Ethical Guidelines for Peer Reviewers</a>)<ul><li>Reviewers should not upload a manuscript or part of a manuscript submitted to them for review to generative AI tools or large language models to assist in the review, evaluation or decision-making process, as uploading content to such AI tools by reviewers violates the authors' privacy and property rights.  </li><li>Reviewing a scientific paper is a responsibility that can only be undertaken by human beings. The critical thinking and original evaluation required for peer review is beyond the scope of this technology, and there is a risk that the technology will produce inaccurate, incomplete or biased conclusions about the paper. The peer review report and decision letters should reflect the personal assessment of the reviewers and editors of the submitted content. The reviewer is responsible and accountable for the content of his/her report. </li><li>AI tools may be used in a limited way to improve the quality of the language of the peer review report (for translation or language editing) in the context of peer review. If such use is made, the reviewer must declare the use when submitting the report. </li><li>Reviewers who suspect inappropriate or undisclosed use of generative AI in a submission should report their concerns to the editor.</li></ul><ul><li> </li></ul>

Editors are obliged to ensure that the confidentiality of the manuscripts submitted to the journal is maintained during the evaluation process, and it is essential that the peer-reviewed work is not shared or used outside the parties involved in that process. (COPE - Code of Conduct and Best Practice Guidelines for Journal Editors) <a href="https://publicationethics.org/files/Code_of_conduct_for_journal_editors_Mar11.pdf" target="_blank">(COPE – Code of Conduct and Best Practice Guidelines for Journal Editors)</a>.<ul><li>Editors should not upload a submitted article, or any part of it, to generative Artificial Intelligence tools or Big Language Models to assist in the review, evaluation or decision-making process, as this may violate authors' privacy and property rights. </li><li>Managing the editorial review of a scientific article implies responsibilities that can only be attributed to humans. Generative AI or AI-assisted technologies should not be used by editors to assist in the evaluation or decision-making process of an article, as the critical thinking and original evaluation required for this task is beyond the scope of this technology and there is a risk that the technology will produce inaccurate, incomplete or biased conclusions about the article. The editor is responsible and accountable for the editorial process, the final decision and its communication to the authors.</li><li>Editors should not use generative AI tools to compose decision letters or abstracts of unpublished research. </li><li>Editors may use generative AI tools to help find appropriate reviewers.</li><li>If editors suspect the use of generative AI in a submitted manuscript or a submitted referee report, they should conduct an editorial review of the matter and consider the policy.</li></ul>

Underlying data should be represented accurately in the paper. A paper should contain sufficient detail and references to permit others to replicate the work. Fraudulent or knowingly inaccurate statements constitute unethical behavior and are unacceptable.Data Access and RetentionAuthors are asked to provide the raw data in connection with a paper for editorial review, and should be prepared to provide public access to such data (consistent with the ALPSP-STM Statement on Data and Databases), if practicable, and should in any event be prepared to retain such data for a reasonable time after publication.Originality and PlagiarismThe authors should ensure that they have written entirely original works, and if the authors have used the work and/or words of others that this has been appropriately cited or quoted.By submitting articles to Turkish Journal of Aquatic Sciences, the author attest the following:·  None of the part of manuscript is plagiarized from other sources·  Proper reference is provided for all contents extracted from other sourcesStrong action will be taken against cases of plagiarismAll the papers submitted have to pass through an initial screening and will be checked through the Advanced Plagiarism Dectection Softwares (iThenticate, Copyleaks).Multiple, Redundant or Concurrent PublicationAn author should not in general publish manuscripts describing essentially the same research in more than one journal or primary publication. Submitting the same manuscript to more than one journal concurrently constitutes unethical publishing behaviour and is unacceptable.Acknowledgement of SourcesProper acknowledgment of the work of others must always be given. Authors should cite publications that have been influential in determining the nature of the reported work.Authorship of the PaperAuthorship should be limited to those who have made a significant contribution to the conception, design, execution, or interpretation of the reported study. All those who have made significant contributions should be listed as co-authors. Where there are others who have participated in certain substantive aspects of the research project, they should be acknowledged or listed as contributors.The corresponding author should ensure that all appropriate co-authors and no inappropriate co-authors are included on the paper, and that all co-authors have seen and approved the final version of the paper and have agreed to its submission for publication.Hazards and Human or Animal SubjectsIf the work involves chemicals, procedures or equipment that have any unusual hazards inherent in their use, the author must clearly identify these in the manuscript.Disclosure and Conflicts of InterestAll authors should disclose in their manuscript any financial or other substantive conflict of interest that might be construed to influence the results or interpretation of their manuscript. All sources of financial support for the project should be disclosed.Fundamental Errors in Published WorksWhen an author discovers a significant error or inaccuracy in his/her own published work, it is the author’s obligation to promptly notify the journal editor or publisher and cooperate with the editor to retract or correct the paper.

The journal conforms to the Principles of Transparency and Best Practice in Scholarly Publishing (doaj.org/bestpractice).Originality, high scientific quality, and citation potential are the most important criteria for a manuscript to be accepted for publication. Manuscripts submitted for evaluation should not have been previously presented or already published in an electronic or printed medium. The journal should be informed of manuscripts that have been submitted to another journal for evaluation and rejected for publication. The submission of previous reviewer reports will expedite the evaluation process. Manuscripts that have been presented in a meeting should be submitted with detailed information on the organization, including the name, date, and location of the organization.Manuscripts submitted to Aquatic Sciences and Engineering will go through a double-blind peer-review process. Each submission will be reviewed by at least two external, independent peer reviewers who are experts in their fields in order to ensure an unbiased evaluation process. The editorial board will invite an external and independent editor to manage the evaluation processes of manuscripts submitted by editors or by the editorial board members of the journal. The Editor in Chief is the final authority in the decision-making process for all submissions.An approval of research protocols by the Ethics Committee in accordance with international agreements (World Medical Association Declaration of Helsinki “Ethical Principles for Medical Research Involving Human Subjects,” amended in October 2013, www.wma.net) is required for experimental, clinical, and drug studies. If required, ethics committee reports or an equivalent official document will be requested from the authors.For manuscripts concerning experimental research on humans, a statement should be included that shows the written informed consent of patients and volunteers was obtained following a detailed explanation of the procedures that they may undergo. Information on patient consent, the name of the ethics committee, and the ethics committee approval number should also be stated in the Materials and Methods section of the manuscript.
