Aquatic Organisms [ds193]

The database focuses on fish, amphibians, insects, crustacean, and other invertebrates, and includes hydrologic information associated with collection sites in inland waterways located in Tuolumne County and the six surrounding counties (Calaveras, Stanislaus, Merced, Mariposa, Mono, and Alpine).

Over seventy-five sources of information were used to develop the dataset including aquatic surveys by several agencies, file reports from the California Department of Fish and Game, personal communications, and research articles as well as museum records from institutions such as the California Academy of Sciences. Collection dates for some data are historical (back to 1889), but the majority range from 1979 to 2003. What each record represents Each record represents the collection, identification, and cataloging of one or more specimens of the given taxon under the location, time, and habitat conditions listed in the record.
