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.

Notropis shumardi (Girard, 1856)

Common name: Silverband Shiner

Taxonomy: available through www.itis.govITIS logo

Identification: Page and Burr (1991); Etnier and Starnes (1993); Pflieger (1997). Gilbert and Bailey (1962) synonymized N. brazosensis, the Brazos River shiner, with N. shumardi. However, it is possible that the two are distinct (Gilbert 1998).

Size: 10 cm.

Native Range: Large rivers of Missouri-Mississippi basin (mainly Missouri, Mississippi, Illinois, Kaskaskia, lower Ohio, Arkansas, and Red rivers), from South Dakota and central Illinois south to Gulf; Gulf Coast drainages, Texas, from Sabine Lake (apparently introduced) to Colorado River (Page and Burr 1991). The Notropis brazosensis form apparently is restricted to the Brazos River, Texas (Hall 1956).

Means of Introduction: Unknown; possible bait bucket releases. The first record of this species in the Red River drainage is that of D. G. Miller (1955) who reported its occurrence near the mouth of the Blue River in Bryan County, Oklahoma. He pointed out the close proximity of tributaries of the Brazos and Red rivers and the possibility of the movement of this and other minnows across the divide during torrential rains. However, he admitted that such a conclusion in no way contradicts the possibility of a bait bucket release. Hubbs and Bonham (1951) regarded the N. brazosensis form as being largely endemic to the Brazos River drainage of Texas (also see Notropis potteri account. Consequently, Hall (1956) considered a bait bucket release as the possible mode of entry into the Red River drainage. He also noted that the N. brazosensis form was being used as a bait fish. However, Hall did not rule out the possibility of natural distribution. Yurgens (1954) reported the N. brazosensis form from Lake Travis (Colorado River drainage) in Texas and speculated that this fish and several other recently discovered minnows were likely introduced as a bait release into the Colorado River drainage. He based his conclusion on the fact that bait dealers had been transporting Brazos River minnows in large numbers to fishing camps on Lake Travis near Austin. In discussing various alternatives to explain its presence in the Red River, Gilbert and Bailey (1962) noted that the Red River may have been "repopulated" from the Texas coastal streams by transfer by man. They reported that there was no positive evidence for the presence of Notropis shumardi in the middle part of the Red River prior to 1953, but added that this is not compelling since the area in question had previously been little collected.

Status: Reported in Louisiana and Texas. Established in Oklahoma.

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.

Remarks: There is uncertainty concerning the native versus nonnative distribution of this species. The N. brazosensis form is apparently in the Red River below Lake Texoma. It may be native to that area, or could be introduced (Gilbert, personal communication). In their book on Oklahoma fishes, Miller and Robison (1973) made no mention the possible introduction of N. shumardi into the Red River. Cross et al. (1986) listed it as native to the lower Red River drainage. Conner and Suttkus (1986) listed it as introduced to the Sabine Lake drainage. Contrary to Yurgens (1954), both Gilbert and Bailey (1962) and Conner and Suttkus (1986) regarded this species as native to the Colorado River drainage of Texas.
