It is global in its scope and is hosted by the California Academy of Sciences.
It has been compiled and is continuously updated by the curator emeritus of the CAS fish collection, William N. Eschmeyer.
The taxonomy maintained by the Catalog of Fishes is considered authoritative and it is used as a baseline reference for instance by the broader global fish database FishBase,[1][2] which involves cross-references to the Catalog's information for all accepted taxa.
A printed 3000-page three-volume and CD version of the Catalogue was published in 1998.
[5] The Catalog was renamed Eschmeyer's Catalog of Fishes in 2019, and is now edited by Ronald Fricke, Richard van der Laan and William N. Eschmeyer.
