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.

Herichthys cyanoguttatus Baird and Girard, 1854

Common name: Rio Grande Cichlid

Synonyms and Other Names: Heros pavonaceus Garman 1881, Parapetenia cyanostigma Hernández-Rolón 1990, Cichlasoma cyanoguttatum; Texas cichlid, Rio Grande perch, mojarra de Norte.

Taxonomy: available through www.itis.govITIS logo

Identification: In general, cichlids (Cichlidae) are superficially similar to North American native sunfishes and black basses (Lepomis and Micropterus; family Centrarchidae). Cichlids can be distinguished from centrarchids by a single nostril opening on each side of the head (vs. two openings in centrarchids) and the presence of a discontinuous or two-part lateral line (continuous in centrarchids).

For distinguishing characteristics and figure see Hubbs et al. (1991) and Page and Burr (1991). Color photographs were given in Conkel (1993).

Size: 30 cm TL (Kullander 2003).

Native Range: Tropical and subtropical America. Northeast Mexico and southern Texas, on the Atlantic Coast from the Río Conchos to the Río Grande basin. Native Texas range limited to the Nueces and Rio Grande drainages (Hubbs et al. 1978). Distribution maps (incomplete) given by Birkhead (1980), Conkel (1993), and Page and Burr (1991).

Ecology: Rio Grande Cichlids occur in riffles or other areas with some degree of water flow over mixed substrate types (rocks, sand, mud, clay) in ponds, lagoons, creeks, rivers, and springs (Robertson and Winemiller 2003; Miller et al. 2005).

Means of Introduction: Herichthys cyanoguttatum was brought to the Guadalupe River drainage by the Fish Cultural Station, part of the U.S. Fish and Wildlife Service, at San Marcos, Texas, in 1928 and released into waters on the Edwards Plateau between 1928 and 1941 or 1943 (Brown 1953; Hubbs et al. 1978). Presumably, San Antonio River stocks came from near Mission, Texas (Hubbs et al. 1978). The species reportedly was introduced first into Florida from Texas stocks around 1941 by a private individual from Mulberry, Polk County. the same individual is reported as having made additional introductions at Mulberry over a period of several years (Courtenay and Hensley 1979). A fish farm may have been the source of introduction into Six Mile Creek, Hillsborough County, Florida, because this species was cultured as an aquarium fish during the 1940s and early 1950s under the trade name "Texas bluespot" (Burgess 1958; Courtenay and Hensley 1979). Some Florida introductions supposedly were due to flooding of resident fish farms (Conkel 1993). Introductions elsewhere were most likely the result of aquarium releases or fish farm escapes.

Status: Introduced and established or locally established in parts of Florida, Louisiana, and Texas. It was established locally in a power plant lake in Illinois but the species no longer is thought to be reproducing in that state (Laird and Page 1996). It was reported from Arizona and Nebraska. Formerly established in Nevada, but now considered extirpated in that state.

Impact of Introduction: Unknown. Lorenz et al. (2011) found that Rio Grande Cichlids were highly aggressive, both as territory holders and entering the territory of Bluegill (Lepomis macrochirus), indicating potential competition for space with native centrarchids and providing a mechanism for continued range expansion in Louisiana.

Remarks: Herichtys cyanoguttatum, naturally occurring in parts of southern Texas, represents the only cichlid native to the United States. According to Courtenay et al. (1974), reports of this species at Gibsonton, Riverview, and Ruskin in Hillsborough County, Florida, by Buntz and Chapman (1970) were based on misidentifications of Jack Dempsey C. octofasciatum. Introduced Texas populations mainly occur in larger springs and spring outflows with favorable water temperatures (Hubbs et al. 1978; Birkhead 1980). It is assumed that the minimum temperature tolerance for C. cyanoguttatum in Texas is between 14.2 degrees Celsius and 19 degrees Celsius, probably closer to 14.2 degrees Celsius (Hubbs 1951).

Lorenz and O'Connell (2008) found reduced growth of Rio Grande Cichlids in the presence of Bluegill (Lepomis macrochirus), indicating the potential for biotic resistance and competition to minimize the impact and spread of Rio Grande Cichlids.

Voucher specimens: Florida (UF 40190, 56196, 91892, 92197), Illinois (SIUC 10805, INHS 68039), Louisiana (SIUC 26460; UNO 9487), Texas (INHS 74255).
