The Journal of Fish Biology is an international peer-reviewed scientific journal that publishes research about fish and aquatic life. It has been published since 1969 and is associated with the Fisheries Society of the British Isles.

The journal covers research on freshwater and marine fish, including their growth, behaviour, reproduction, genetics, ecology, physiology, migration, conservation and responses to environmental change.

It is published by Wiley and includes research papers that undergo scientific peer review before publication. The journal is also indexed in major academic databases such as PubMed/MEDLINE, Scopus and Web of Science.

In simple terms, it is a specialist scientific journal where researchers publish studies that improve our understanding of fish biology and conservation.
