Simple Search provides you a simple way of reaching mitogenomic data of each species. Enter a scientific name/common name of fish or DDBJ/EMBL/GenBank/RefSeq accession number into the search box.

Examples of search terms:

• Anguilliformes (for Order name)
• Anguillidae (for Family name)
• Anguilla (for Genus name)
• Anguilla japonica (for Species name, synonym is OK)
• eel (for common name, might result in large amount of results)
• AB038556 (for DDBJ/EMBL/GenBank accession number)
• NC_002707 (for RefSeq accession number)

Then, click on the Search button, and you will find a list showing data availability.
This list then leads you to the data and other related information sources for each species.

Since 2023, MitoFish supports seaching using synonyms and/or common names. Scientific names from NCBI Taxonomy Database are shown in the result table, while other names can be viewed by clicking the icon in the left side of each row.

Since 2023, MitoFish supports downloading sequences in FASTA format from searching results if less than 1000 rows. You can choose whether to download the whole mitogenome or single genes.

Advanced Search provides more detailed Search and Report Options. For the Search Options, provided are the following search options other than fish names and DDBJ/EMBL/GenBank accession number: RefSeq accession number, Voucher specimen number, PubMed ID, and Reference. For Report Options, ascending and descending sorting options are provided for each taxonomic category for listing.

This menu leads you to mitogenomic data through the taxonomy. It first shows a list of all fish orders. Clicking on an order name, you will find a list of species within the order, whose complete mitochondrial genome data are available.

This directly provides you a list of all fishes whose complete mitochondrial genome data are available.
