The zebrafish is a widely used model organism for genetic, genomic, and developmental studies, and ZFIN provides an integrated interface for querying and displaying the large volume of data generated by this research.

[3] Abundant links to external sequence databases (e.g., GenBank) and to genome browsers are included.

ZFIN is based at the University of Oregon in the United States, with funding provided by the National Institutes of Health (NIH).

ZFIN's relational database interface provides query forms and display pages for the following biological data types: ZFIN also maintains a database of zebrafish-related publications, laboratories, people, and companies.

ZFIN's community wiki gives zebrafish researchers the ability to share information about laboratory protocols and antibodies.
