Zebrafish Genome Project

Danio rerio reference genome assemblies and assemblies of additional D. rerio strains and Danio and Danionella species.

The zebrafish genome project at the Wellcome Sanger Institute produced the zebrafish reference assembly of the Tuebingen strain. After the release of Zv9, the project joined the Genome Reference Consortium (GRC) for further improvement and ongoing maintenance. The GRC has now released a new reference assembly, GRCz11. Our GRC partners at ZFIN have agreed to take over the responsibility for further updates and maintenance.

We have created several additional assemblies as part of the Danioniae Sequencing Project. These include D. rerio strains (SAT, AB, Cooch Behar, Nadia) and close relatives from the Danio and Danionella clade. The assemblies are publicly available, please consult our data release policy.

Data Release Policy

The Zebrafish Genomes Project releases sequence data and variant calls as a service to the research community. These data are released in accordance with the Fort Lauderdale agreement and Toronto agreements. As producers of these data we reserve the right to be the first to publish a genome-wide analysis of the data we have generated. The pre-publication data that we release via this website is embargoed for publication except for analyses of single chromosomes in single strains or single gene loci across multiple strains. We strongly encourage researchers to contact us if there are any queries about referencing or publishing analysis based on pre-publication data obtained via this website. More information on the Wellcome Sanger Institute’s data sharing policy.

If you have a query about using the project data in your studies or publications, we are happy to answer any queries and can be contacted at

Data use

This sequencing centre plans on publishing the completed and annotated sequences in a peer-reviewed journal as soon as possible. Permission of the principal investigator should be obtained before publishing analyses of the sequence/open reading frames/genes on a chromosome or genome scale. See our data sharing policy.
