The Nonindigenous Occurrences section of the NAS species profiles has a new structure. The section is now dynamically updated from the NAS database to ensure that it contains the most current and accurate information. Occurrences are summarized in Table 1, alphabetically by state, with years of earliest and most recent observations, and the tally and names of drainages where the species was observed. The table contains hyperlinks to collections tables of specimens based on the states, years, and drainages selected. References to specimens that were not obtained through sighting reports and personal communications are found through the hyperlink in the Table 1 caption or through the individual specimens linked in the collections tables.

Nonindigenous Occurrences: Four young River Carpsuckers were collected in 1927 in a tributary to the lower Maumee River, Ohio (Lee et al. 1980 et seq.; Trautman 1981; Page and Burr 1991).  Some doubt exists about the veracity of this record.  Trautman (1981) says there is doubt about his and Carl L. Hubbs ability to identify young of this species. Since no others have ever been collected, he posed three possibilities: 1) they were introduced with shipments of buffalo and failed to become established; 2) an Ohio drainage collection was mixed with a Maumee collection; or 3) a relict population exists.  He considered the first possibility the most probable.

† Populations may not be currently present.

Means of Introduction: It is likely that individuals of this species were included in shipments of buffalo-fishes Ictiobus spp., which were intentionally stocked in Ohio in western Lake Erie between 1920 and 1930 (Lee et al. 1980 et seq.; Trautman 1981).

Status: Failed in Ohio.

Impact of Introduction: The impacts of this species are currently unknown, as no studies have been done to determine how it has affected ecosystems in the invaded range. The absence of data does not equate to lack of effects. It does, however, mean that research is required to evaluate effects before conclusions can be made.
