Main text. Generally, all papers should be divided into the following sections and
appear in the order: (1) Abstract or Summary, not exceeding 150-200 words, (2)
Introduction, (3) Materials and Methods, (4) Results, (5) Discussion, (6)
Acknowledgments, (7) References, (8) Figure legends, (9) Tables, (10) Figures.
The Results and Discussion sections may be combined and may contain
subheadings. The Materials and Methods section should be sufficiently detailed to
enable the experiments to be reproduced. Trade names should be capitalized and
the manufacturer's name and address given.
All pages must be numbered consecutively from the title page, and include the
acknowledgments, references and figure legends, which should be submitted on
separate sheets following the main text. The preferred position of tables and figures
in the text should be indicated in the left-hand margin.
Units and spellings. Systeme International (SI) units should be used. The salinity of
sea water should be given as gL-1. Use the form gmL-1 not g/ml. Avoid the use of g
per 100 g, for example in food composition, use g kg-1. If other units are used, these
should be defined on first appearance in terms of SI units, e.g. mmHg. Spelling
should conform to that used in the Concise Oxford Dictionary published by Oxford
University Press. Abbreviations of chemical and other names should be defined when
first mentioned in the text unless they are commonly used and internationally known
and accepted.
Scientific names and statistics. Complete scientific names, including the authority
with correct taxonomic disposition, should be given when organisms are first
mentioned in the text and in tables, figures and key words together with authorities in
brackets, e.g. 'rainbow trout,
Oncoryhnchus mykiss (Walbaum)' but 'Atlantic salmon
Salmo salar L.' without brackets. For further information see American Fisheries
Society Special Publication No. 20, A List of Common and Scientific Names of Fishes
from the United States and Canada.
Carry out and describe all appropriate statistical analyses.
References (Harvard style). References should be cited in the text by author and
date, e.g. Lie & Hemre (1990). Joint authors should be referred to in full at the first
mention and thereafter by et al. if there are more than two, e.g. Hemre et al. (1990).
More than one paper from the same author(s) in the same year must be identified by
the letters a, b, c, etc. placed after the year of publication. Listings of references in
the text should be chronological. At the end of the paper, references should be listed
alphabetically according to the first named author. The full titles of papers, chapters
and books should be given, with the first and last page numbers.
