Scope and policy

The journal Neotropical Ichthyology publishes original articles on Neotropical freshwater and marine fish in the areas of Biology, Ecology, Ethology, Genetics and Molecular Biology, Physiology, and Systematics.

Submitted manuscripts must be relevant contributions within their specific research area and must provide clear theoretical foundations of the subject, description of the objectives and / or hypotheses under consideration, in addition to sampling and analytical designs consistent with the proposal. Descriptive original works of high quality and relevance will be considered for publication. Casual observations, scientific notes or studies merely descriptive not associated with relevant theoretical issues will not be considered.

Editor and Section Editor of the area will evaluate the submitted manuscript to determine if its content is suitable for publication in the journal Neotropical Ichthyology. The Journal is open for submissions to all researchers on Neotropical ichthyofauna. Payment of publication costs may be required if none of the authors is a member of the Brazilian Society of Ichthyology.


Submission of manuscripts

All co-authors and respective e-mails must be registered in the appropriate forms along with manuscript submission.

During the submission, indicate the area of Ichthyology (Biochemistry and Physiology, Biology, Ecology, Ethology, Genetics and Molecular Biology, Systematics) to which the manuscript is referable.

During the submission, indicate three possible referees (name, institution, country, and e-mail).

Manuscripts that are not formatted according to instructions to authors will be returned to authors.

Manuscripts submitted in poor English will be returned without review. Appropriate use of the English language is a requirement for review and publication.
