The source of this coverage data set is the fish biodiversity maps created for The Nature Conservancy (TNC) as part of their Hexagon Project. Professor Peter Moyle and his graduate student, Paul Randall, of the Department of Wildlife and Fisheries Conservation Biology at the University of California, Davis were hired to produce range maps for all known fish species that presently occur in California. Each coverage denotes a separate fish species (refer to the species coverage key below). The polygons are estimated to be accurate at a scale of roughly 1:1,000,000. Other California fish species distributions can be found in a gallery at:
