Nonindigenous Fishes
Listed in NASA Earthdata CMR
The data set includes information on fish species introductions, including locations, methods of introduction and status of the introduction.
Description
The fishes database includes information on over 450 species. Most are freshwater introductions, although a few marine species are included.
The purpose of this data set is to document the introductions and spread of nonindigenous fishes. Records are entered into DBase from the sources listed above. Scientific names are checked against the most current AFS list or more recent literature to ensure correct taxonomy.

The location is verified on a map and used to obtain the county (if not provided) and related to the smallest possible USGS HUC. The date of the observation is recorded (if given). If a date is not given, the publication date of the source is used.
When dates are vague, a judgement is made about what date to enter. i.e., mid 1970's, 1975 is entered. If the record is from a published source, the reference is given a reference number and entered into the REF column and into the reference database. Files are kept of references by number.
If the record is the result of a report from someone, that person is listed as the contact.
