ARTICLE EVALUATION AND PUBLICATION PROCESS
Articles submitted to COMU-JMSF are primarily evaluated by the technical editors. Manuscripts are pre-checked by the technical editors for compliance with the submission and writing rules of the Journal. If a deficiency or error is detected, it is sent back to the author.
After this process, the editor-in-chief review the manuscript (initial evaluation process). At this stage, articles not having suitable scope and aims, with low original research value, containing scientific and ethically important errors, having low potential to contribute to science and the journal, and having poor language and narration are rejected by the editor without peer-review process.
Articles that are deemed appropriate for editorial evaluation are sent to the section editor related to the category of articles to be examined in terms of scientific competence. The section editors examine the article in all aspects. Peer-review process is applied to the articles that have completed preliminary evaluation process. At least 2 referees who are experts in their fields are assigned. Each manuscript is reviewed through a double-blind peer-review process (identities of authors and peer reviewers are disclosed). At this stage, referees send their decision (reject, revision or accept) about the article to subject editors. Section editors take the final decision (Accept, Reject) of manuscript in line with the reviewer opinions and report their decisions to Editor-in-Chief.
The articles that have completed the peer-review evaluation stages and accepted by the Editor-in-Chief are sent to the corresponding author for final checks and necessary final additions. After the acceptance, the article designed in the publication format of the journal is given an DOI number and published immediately in COMU-JMSF page.
All responsibility for the scientific content and expressions in the published article belongs to the authors.

Editors and journal staff as authors
Editors and editorial team members are excluded from publication decisions when they are authors or have contributed to a manuscript.
Editors/editorial board members do not make decisions about works written by them or co-author(s). The usual procedure applies for this type of manuscript. The process continues without the relevant author being included in the evaluation process (preliminary evaluation and peer-review process) in the journal.

PLAGIARISM AND ETHICAL ISSUES

Manuscripts that are submitted to our journal are meticoulsly examined for plagiarism and ethical issues. The following are taken into consideration during this process.
Plagiarism
Plagiarism is the unattributed use of another author’s work. Plagiarism may take different forms; for example, while literal copying or substantial copying is considered plagiarism, paraphrasing the work of another author is also considered as plagiarism. In order to prevent potential plagiarism problems, manuscripts submitted to Çanakkale Onsekiz Mart University, Journal of Marine and Fisheries Sciences (COMU-JMSF) are screened for similarity using IThenticate (http://www.ithenticate.com/) software. Manuscripts with a similarity index of 30% or less will be accepted for further reviewing. Manuscripts with higher similarity than 30% are examined in detail and, if necessariy, sent back to authors for review and correction. Manuscripts are rejected when plagiarism is detected.
Non original work
Non original work arises when non-existent or manipulated data are used in scientific studies. When necessary, the editor may require further information with regard to when, where and how the study was carried out. This information is important for originality of the work.
Authorship of contribution
Our journal requires that, although the concept of authorship is defined vaguely, contributions by all authors should clearly be defined and non-contributors or those with trivial contributions should not be conferred the status of author. In addition, all contributors should approve the final draft of the manuscript. In essence, an author should also be able to defend the paper. When necessary, the editör, may ask all authors
Redundant Publication
Redundant publication or double publication refers to publishing the same manuscript more than once. It is very important that manuscripts submitted to our journal should be original work and should not have been submitted to other journals. In addition, data slicing that involves segmentation of a single study into multiple publications should be avoided.
The following summarizes other important unethical issues in submitting manuscripts to our journal:
• Not indicating whether the manuscript is produced from the author’s Masters/PhD thesis or a project.
• Using someone’s unpublished material without permission of the author.
• Breaching ethical rules in experiments involving humans or animals.
• Not considering animal welfare, biological diversity and habitat conservation
• Conducting experiments involving animals without appropriate authorization or permission.
In addition to above mentioned issues, authors are expected to declare conflict of interest in connection with the manuscript, for unbiased reviewing.
