The structure of the article consists of Introduction, Materials and Methods, Results and Discussion, Conclusion, Acknowledgment (optional), and References. The short communication (1500-3000 words) receives the same in-depth review as the Research Article.

3. Review Article (Narrative Review, Systematic Review, Meta-Analysis, Critical Review)

A survey, evaluation and critical interpretation of recent research, data, and concepts in the field of fisheries or marine sciences. This article should be typed within more than 15 pages or minimum 7000 words (including figures and tables).

FORMAT FOR WRITING A REVIEW ARTICLE 

A high-quality review article published in reputable international journal (JIPK format) must follow a systematic structure with a clear methodology. Below is the standard format recommended for Narrative Review, Systematic Review, Meta-Analysis, and Critical Review articles.

1. Title

• Should be specific, clear, and reflect the scope of the review.
• Avoid overly general terms while keeping the title informative and engaging.
• Example: Recent Advances in Sustainable Aquaculture: A Systematic Literature Review of Growth, Challenges, and Future Prospects.

2. Abstract

• 150–250 words, structured to include:
  ✅ Background (Why is this topic important?)
  ✅ Objective of the review (What does this paper aim to achieve?)
  ✅ Methods (If systematic review or meta-analysis, mention literature search strategy)
  ✅ Main findings (Key insights from the reviewed literature)
  ✅ Research implications (How this review contributes to the field)

• Example:

This review explores the latest advancements in sustainable aquaculture, focusing on technological innovations, environmental impact, and future challenges. A systematic literature review was conducted using databases such as Scopus and Web of Science, covering articles published from 2015 to 2024. Findings indicate that sustainable aquaculture is advancing through precision aquaculture technologies, yet challenges remain in waste management and policy regulation. This review highlights key gaps and provides recommendations for future research directions.

• Keywords: 5–7 words that accurately represent the article’s content.
  Example: sustainable aquaculture, precision farming, fishery management, water quality, environmental impact

3. Introduction

• Explain the background and importance of the topic under review.
• Outline the state-of-the-art in the field and justify why this review is necessary.
• Define the objectives of the review and its scientific contribution.
• If systematic review, specify the research question following PRISMA or other systematic methodologies.

📌 Ideal Structure:
✅ General background of the topic
✅ Significance and scientific relevance
✅ Research gap to be addressed
✅ Objectives and scope of the review

4. Methodology (Optional, but Required for Systematic Literature Review & Meta-Analysis)

• Systematic Literature Review → Follow a structured method like PRISMA (Preferred Reporting Items for Systematic Literature Reviews and Meta-Analyses) to explain how literature was searched, selected, and analyzed.
• Meta-Analysis → Include data extraction process, statistical methods, and inclusion/exclusion criteria.
• If Narrative Review or Critical Review, describe the literature search strategy descriptively.

📌 Key Methodology Sections:
✅ Databases used (Scopus, WoS, PubMed, etc.)
✅ Search keywords
✅ Inclusion and exclusion criteria
✅ Data analysis methods (for meta-analysis)

5. Results and Discussion

• Organize content into well-defined subtopics (use subheadings for each major theme).
• Use tables and figures where necessary to summarize findings.
• Provide synthesis and comparative analysis rather than merely summarizing studies.
• Critically analyze trends, discrepancies in findings, and future research potential.

📌 Recommended Structure:
✅ Clearly defined themes/subtopics (e.g., “Sustainability in Marine Fisheries,” “Technological Innovations in Aquaculture”)
✅ Summary tables of key literature (if applicable)
✅ Comparison of findings across different studies
✅ Identification of research gaps

❌ Common Mistakes to Avoid:
❌ Simply listing studies without providing synthesis or critical discussion.
❌ Failing to connect findings to existing theories or frameworks.

6. Conclusion and Implications

• Summarize the key insights from the review.
• Discuss practical and theoretical implications for future research.
• Mention the limitations of the review and suggest future research directions.
• If relevant, provide policy or industry recommendations.

📌 Ideal Format:
✅ Summary of key findings
✅ Scientific contribution
✅ Study limitations
✅ Future research directions

7. References

• Follow the reference style required by the JIPK Style.
• Use primary sources from reputable journals (Scopus, WoS, PubMed) and avoid citing non-academic websites or blogs.
• Utilize reference management tools like Mendeley, EndNote, or Zotero to ensure consistency in citation formatting.

📌 JIPK Style:
✅ Journal Article:

Smith, J., Jhon, T. N., Rozi, M. & Doe, A. (2023). The impact of climate change on marine biodiversity. Marine Ecology Journal, 58(2):145-162. https://doi.org/xxxxx

✅ Book:

Brown, K. (2020). Sustainable Fisheries Management. Springer.

8. Appendices 

• Could include a PRISMA Flowchart for systematic review.
• Additional Graphic and tables if necessary for reference.

📌 Final Checklist for Review Article 

✅ Title is clear, specific, and reflects the review topic
✅ Abstract is concise (150-250 words) with relevant keywords
✅ Introduction presents research gaps and review objectives
✅ Methodology is transparent (for systematic literature review/meta-analysis)
✅ Results and discussion provide synthesis, not just summaries
✅ Conclusion aligns with research implications and future directions
✅ References are from high-quality, reputable journals
✅ Formatting follows the target journal’s guidelines (JIPK style)

FORMAT FOR WRITING RESEARCH ARTICLE AND SHORT COMMUNICATION

Accepted File Formats

- Materials to Submit 

Authors must use the Document template to prepare their manuscript. Using the template file will substantially shorten the time to complete copy-editing and publication of accepted manuscripts. The total amount of data for all files must not exceed 120 MB. If this is a problem, please contact the editorial office jipk@fpk.unair.ac.id. Accepted file formats are:

• Microsoft Word: Manuscripts prepared in Microsoft Word must be converted into a single file before submission. Please insert your graphics (schemes, figures, etc.) in the main text after references.
• Supplementary files: May be any format, but it is recommended that you use common, non-proprietary formats where possible (see below for further details).
• Assemble manuscripts in this order: title page, abstract page, text, references, tables, figure captions. Tables may be included at the end of the article file or may be submitted as separate files. Figures should not be embedded in the article file and should be submitted separately. 
• Authors are strongly encouraged to submit a word processing file in either Word or plain text format. 
• Figures/images should be in JPG or TIFF (preferred) formats with HD resolution (minimum 600 dpi), and tables should be in Excel or Word formats. 
• Word count is extremely important. (See limits for article types above.) 
• The cover letter should explain how your paper is the authors contribution, highlight research, type paper, and ethical approval (If available). It should also include a list of potential reviewers who can provide an unbiased, informed, and thorough assessment of the manuscript. The cover letter can also be used to provide further explanation if part of the information has been published or presented previously. 

- General Instructions

• Consult current issues for additional guidance on format. 
• Manuscripts should be single-spaced, including tables, references, and figure captions. 
• Leave at least a 2.5 cm-in margin on all sides. Indent all paragraphs. Number pages sequentially and use continuous line numbering, 
• Use dictionary preference for hyphenation. Do not hyphenate a word at the end of a line. Use Chicago Manual of Style to answer grammar or usage questions. 
• The first mention of a common name should be followed by the scientific name in parentheses. Our standard is the current edition of Common and Scientific Names of Fishes from the United States, Canada, and Mexico. For other aquatic species, authors should follow the companion publications World Fishes Important to North Americans and Common and Scientific Names of Aquatic Invertebrates from the United States and Canada (the volumes Mollusks, Decapod Crustaceans, and Cnidaria and Ctenophora are currently available in the latter series).
• Define abbreviations the first time they are used in the text. 
• Spell out one-digit numbers unless they are units of measure (e.g., four fishes, 3 mm, 35 sites). Use 1,000 instead of 1000; 0.13 instead of .13; % instead of percent. 
• Use the name-and-year system for references in the text as follows: 

1. One author: Sri (2009) or (Wahju, 2005); 
2. Two authors: Nina and Dwi (2007) or (Rozi and Ghoyatul, 2008); 
3. Several authors: Luthfiana et al., (1995) or (Dwitha et al., 1995). But include author names in references. 
4. Manuscripts accepted for publication but not yet published: Rozi and Ghoyatul (in press) or ( Rozi and Ghoyatul in press). 
5. Personal communications: (J. Ghoyatul, Institute for Aquatics, pers. comm.). 
6. Within parentheses, use a semicolon to separate different types of citations (Figure 1; Table 2; Table 5), (Rozi and Ghoyatul, 2008; Sri and Wahju, 2009; Nina and Dwi, 2015). Arrange lists of citations chronologically (oldest first) in a text sentence. 

• DO NOT cite more than three references for a specific point. 
• Institutional authors may be cited as acronyms in the text but must be defined in the reference list.
• Avoid the expressions "the mean length of goramy fish was 45.2 ± 3.84 mm” and "the mean (±SD) length was 45.2 ± 3.84 mm” because they are at best awkward and at worst inaccurate. Use the expressions "the mean ± SD length of goramy fish was 45.2 ± 3.84 mm” or "the mean length was 45.2 mm (SD, 3.84)” instead.
• Only symbols and abbreviations included in Webster's dictionaries or listed at the end of these guidelines (as well as at the back of each printed issue of the journal) may be used without definition. All others should be defined at first use (e.g., index of biotic integrity [IBI]). Abbreviations should not be introduced unless they are used at least two more times.
• All measurements should be given in metric units. The only exceptions are a few quantities that are typically expressed only one way (e.g., g [of medication]/lb [of feed]).
• Single-digit numbers should be spelled out unless they are used with units of measure or in conjunction with larger values (e.g., 2 mg/L; 8 Walleyes and 16 Saugers). Numbers with four or more digits should contain commas; those less than 1.00 should be preceded by zeroes.
• Ratios involving two values or units of measure should be indicated by forward slashes (e.g., 0.30 g/d); ratios involving three such terms should be indicated by negative exponents (e.g., 0.01 g · g–1 · d–1).
• Ages of fish should be expressed by Arabic numerals and not contain plus signs (e.g., a fish is age 1 [not age 1+] from the January 1 after it hatches to the following December 31).
• Dates should be expressed as month–day–year (e.g., January 11, 2011). Note that the term "Julian day” does not mean day of the year and should not be used in that context.
• Time should be expressed in terms of the 24-hour clock followed by the word "hours” (e.g., 14:35 hours rather than 2:35 p.m.).

Figures and Tables placed separated in the last page of the manuscript.

The Rules of Tables and Figures 

A. Tables (Title in an English, Bold in Table, Time New Roman 11pt, Align left)

Tables must be submitted in MS Word documents using the "Tables” tools, or as MS Excel files. Do not send tables as un-editable pictures that have been pasted into the document.

• Tables may be included with the article or submitted as separate files. 
• Single-space everything, including the table title and column headings. 
• Use single horizontal lines to separate column heads and to indicate the end of the table”other horizontal lines are not needed. Never use vertical lines. 
• Use sentence-style captions for tables, not fragments. 
• Capitalize only the first letter of the first word in each column and row entry (except initial caps for proper nouns) and make your text of table in Bold type each word. 
• Tab between column items ” DO NOT "space” between columns. 
• Type "NA” (not applicable) where no entry applies in the table body. Do not add filler dashes. \Label footnotes with lowercase, superscript letters, starting from the beginning of the alphabet (a, b, c). 
• Redefine, in the table's caption or in a footnote, any acronyms that are used in the table but are mentioned only infrequently in the text.

Tables should be embedded on the last page. Provide footnotes and other information (e.g., source/copyright data, explanation of boldface). Tables should be no wider than 17 cm. Condense or divide larger tables. Please submit tables as editable text and not as images. Number tables consecutively in accordance with their appearance in the text and place any table notes below the table body. Be sparing in the use of tables and ensure that the data presented in them do not duplicate results described elsewhere in the article. Please avoid using vertical rules and shading in table cells.

Equations (refer with Eq. 1, Eq. 2,..) should be indented 5 mm (0.2”). There should be one line of space above the equation and one line of space below it before the text continues. The equations have to be numbered sequentially, and the number put in parentheses at the right-hand edge of the text. Equations should be punctuated as if they were an ordinary part of the text. Punctuation appears after the equation but before the equation number. The use of Microsoft Equation is allowed. Example c2 = a2 + b2. (1)

 B. Figures (Title in an English, Bold in Figure, Time New Roman 11pt, Align left)

The example of figure can be seen below.

 Figure 1. Intestinal morphology of Anguilla bicolor bicolor. Histology analysis was made on the front (1), mid (2), and posterior (3) parts of the anterior intestines.

Figure 2. Hemolytic activity test of Enterobacter sp. JC05, Lactococcus sp. JAL37, and Bacillus sp. PCP1 on a blood agar produced from pure sheep blood. The presence of a greenish halo indicated an α-hemolysis, whereas the absence of a halo indicated a γ-hemolysis (Ghosh et al., 2021)

Jurnal Ilmiah Perikanan dan Kelautan, 14(2):203-213. http://doi.org/10.20473/jipk.v14i2.34315

Provide figures embedded in the page. Figures should be drawn professionally. Photographs should be sharp (contrast). Provide footnotes and other information (e.g., source/copyright data, explanation of boldface) in the figure legend. Submit image files (e.g., electromicrograph) without text content as high-resolution (600 dpi/PPI minimum) TIFF or JPG files. Ensure that each illustration has a caption. Supply captions separately, not attached to the figure. A caption should comprise a brief title (not on the figure itself) and a description of the illustration. Keep text in the illustrations themselves to a minimum but explain all symbols and abbreviations used.

Check that pictures resolution is enough to disclose important details on the picture. Please check all the pictures either on the screen and the results in the print version. When examined images printed version, make sure that: color have quite a contrast, a picture is quite clear and all the labels on a picture can be read. Colored charts images are possible. Do not use dot pattern on charts since there is the possibility it can't be printed in its original. Use solid fill and contrast color in charts images.

Illustrations

Line drawings
All lines must be sufficiently thick (1 points minimum) to reproduce well, and all symbols, superscripts, subscripts, and decimal points must be in good proportion to the rest of the drawing and large enough to allow for any necessary reduction without loss of detail. Avoid small open symbols; these tend to fill in upon reproduction. The same font style and lettering sizes should be used for all figures of similar size in any one paper. Original recorder tracings of NMR, IR, ESR spectra, etc., are not acceptable for reproduction; they must be redrawn.

Maps
Proper attribution must be given to the source of map data. Permission requirements can generally be found on the website of the map source, and attribution information generally appears on the bottom corner of the map. See attribution guidelines for Google Maps, for example, at https://www.google.ca/permissions/geoguidelines/attr-guide/. Please provide the attribution information in the figure caption if it is not clearly visible on the map. Maps must have very clear, bold patterns and must show longitudes and latitudes (or UTM coordinates) and a scale, to ensure proper identification of study locations. On maps of Quebec, the official name of municipalities must be used (e.g., Surabaya City) and physical features must be in English (e.g., Lake Abitibi ) except for those that are considered of local name significance in English and French (e.g., Atlantic Ocean and Océan Atlantik) and should appear in the language of the paper.

Photographs

Photographs should be continuous tone, of high quality, and with strong contrast. Only essential features should be shown. A photograph, or group of them, should be planned to fit into the area of either one or two columns of text with no further reduction. Electron micrographs or photomicrographs must include a scale bar directly on the illustration. Please do not use magnification. The best results will be obtained if the authors match the contrast and density of all figures arranged as a single plate.

Colour illustrations
Colour illustrations will be at the author's expense. Authors must submit a Colour Authorization Form with approval of the author or institution who will pay for the colour reproduction. Further details on the info you could contact the Journal Editorial Office.
Colour illustrations should use contrasting colours rather than colours very close in hue, or differentiate similar colours by inserting patterns over the colours (e.g., stippling, hatching). When a figure is to appear in colour online and in black and white in print, authors must supply only a single colour version of the illustration (rather than one colour version and one black-and-white version). The figure caption should provide a clear explanation of the figure whether the figure is being viewed in the online or print version of the Journal (for example, instead of "the red and blue symbols”, write "the red circles and blue squares”).

Structural drawings
Structures and schemes should be placed on separate pages (not within the text). The use of a computer drawing program such as ChemDraw or ChemWindows is highly recommended. Single-width bold and broken lines are preferred to wedges for stereochemical notation; 12-pt Time new Roman font should be used for atom labels.

Graphical abstracts
Graphical abstracts are published as part of the Table of Contents (applies to JIPK only). The graphical abstract may consist of a small structural diagram, equation, or other informative drawings that serve to illustrate the subject of the article. The authors should note that the maximum allowable size of the final reproduction is 40 mm high by 85 mm wide without text (except necessary labels) and should plan accordingly. The graphical abstract must be submitted in an electronic format.

Preparation of electronic graphic files
JIPK prefers the submission of illustrations, figures, and other artwork (such as multimedia) for accepted manuscripts in an electronic format and will use these electronic files whenever possible to ensure accuracy, clarity, and the highest level of detail.

See the electronic graphics list at http://nrcresearchpress.com/page/authors/information/graphics for accepted file formats.

Windows or Macintosh versions of True Type or Type 1 fonts should be used. Do not use bitmap or nonstandard fonts.

All figures should be submitted at the desired published size. For figures with several parts (e.g., a, b, c, d, etc.) created using the same software application, assemble them into one file rather than sending several files.

Remember that the more complex your artwork becomes, the greater the possibility for problems at output time. Avoid complicated textures and shadings, especially in vector illustration programs; this increases the chance for a poor-quality final product.

Bitmap (raster) files the proper resolution should be used when submitting bitmap artwork. The minimum requirements for resolution are 600 dpi for line art, 1200 dpi for fine lines (line art with fine lines or shading), 300 dpi for halftones and colour, and 600 dpi for combinations (halftones with lettering outside the photo area).

All colour files submitted must be as CMYK (cyan, magenta, yellow, and black). These colours are used in full-colour commercial printing. RGB graphics (red, green, and blue; colours specifically used to produce an image on a monitor) will not print correctly.

Vector files are image files produced using elements such as lines and shapes. Typically these files are used for line drawings.

Bitmaps inside vector files Bitmaps can be imported into vector/draw applications only for the purpose of adding and overlaying information, lines, text, etc. Bitmaps should not be resized, cropped, rotated, or otherwise manipulated after importing.

Multimedia files
The Journal allows authors to incorporate audio and video clips into their paper; these are published in the online version of the Journal, adding a dimension to the paper that cannot be achieved in the printed version. For submission guidelines and accepted formats, see the List of Accepted Graphic Files at http://nrcresearchpress.com/page/authors/information/graphics.

Spelling
Spelling should follow Webster's Third New International Dictionary or the Oxford English Dictionary. Authors are responsible for consistency in spelling.

Nomenclature, abbreviations, and acronyms
Nomenclature and abbreviations should follow the rules recommended by the International Union of Biochemistry (IUB) Committee of Editors of Biochemical Journals with support of IUPAC. As a general guide for biological terms, Scientific Style and Format: The CSE Manual for Authors, Editors, and Publishers (8th ed., 2014; http://www.scientificstyleandformat.org/Home.html), published by the Council of Science Editors, is recommended. For enzyme nomenclature, Enzyme Nomenclature (1992): Recommendations of the Nomenclature Committee of the International Union of Biochemistry and Molecular Biology (Academic Press, San Diego, Calif.) should be followed.

Abbreviations and acronyms that are standard in the discipline need not be defined. All others must be defined when they are first mentioned in the text and those with more than one meaning should be avoided.

Units of measurement
SI units (Système international d'unités) should be used or SI equivalents should be given. Avoid ambiguous forms such as g C/m2/day; use g C·m–2·day–1. This system is explained and other useful information is given in the Metric Practice Guide (2000) published by CSA International (178 Rexdale Blvd., Toronto, ON M9W 1R3, Canada). For practical reasons, some exceptions to SI units are allowed. Units such as kilocalorie, reciprocal centimetre (wave number), and atmosphere may be used for the foreseeable future.

Statistical analyses
The assumptions and (or) the model underlying any statistical analysis should be clearly stated. Symbols such as * and **, denoting levels of significance, should not be used except in conjunction with the actual values of the associated test statistic; actual p values are preferred.

Fish
The Journal follows the names and spelling for fishes recommended in Common and Scientific Names of Fishes from the United States, Canada, and Mexico (7th ed., Spec. Publ. No. 34, American Fisheries Society, 2004) and the gene nomenclature for protein-coding loci outlined in Shaklee et al. (Trans. Am. Fish. Soc. 119: 2–15, 1990).

Writing numbers
In writing long numbers, the digits should be separated into groups of three, counted from the decimal marker to the left and right. The separator should be a space and not a comma, period, or any other mark, for example, 25 562 987 and not 25,562,987. In English text, the decimal marker should be a point, for example, 0.1 mL and not 0,1 mL. The decimal point in all numbers between 1 and –1, except 0, must be preceded by a 0. The sign í— should be used to indicate multiplication, e.g., 3 í— 106 and not 3·106.
