Garman S, 1881. Illinois, USA: The University of Chicago Press. Phase I Report. Habitat associations of fishes in the Devils River, Texas. Kullander SO, 2003. It has also been introduced into the Concho, Nueces, lower Brazos, San Marcos Rivers, Town Lake Reservoir (in southeast Austin), Lake Houston, West Matagorda Bay, Simms Bayou and Cibolo drainages (Hubbs et al., 1991; Nico et al., 2015). Revue francaise des Cichlidophiles, 11(101):4-13. There are several small black spots at the base of the caudal fin and along the middle, rear half of the body. San Antonio River Authority biologists in Texas have observed that H. cyanoguttatus will displace native Centrarchidae in stressed habitats and dominate the ecosystem (Gonzales and Moran, 2005). Texas Parks and Wildlife call it a Rio Grande Cichlid so thats what I go by. © Copyright 2021 CAB International. FishBase. Page LM; Burr BM, 1991. Blue tilapia are also known to impact a number of minnows and topminnows such as shiners, chub, pupfish, and mosquitofish -- including some imperiled species -- through habitat degradation, competition for incidental consumption of eggs through herbivory, predation on small and/or young fishes, and distu… In Florida, USA, H. cyanoguttatus has been collected from several locations in Tampa as early as the 1940s (Nico et al., 2015). A revision of the South American cichlid genus Cichlasoma (Teleostei: Cichlidae). Similarly, Lorenz (2008) cited anecdotal evidence of the decline of Gambusia affinis, Poecilia latipinna and Heterandria formosa in areas of Louisiana where H. cyanoguttatus has become well established. CABI, Undated. Tomelleri and Eberle (1990) report that the species can only survive cool winters in the ‘cooling lakes’ of power plants or in rivers near the outlets of warm springs at the northern limit of its distribution in the Edwards Plateau (Texas). Porto Alegre, Brasil: EDIPUCRS. Lorenz OT, 2008. The Rio Grande or Texas cichlid Herichthys cyanoguttatus is a popular ornamental freshwater fish that has been introduced to a number of US states.Its wide environmental tolerances, ability to colonize disturbed habitats, trophic opportunism, fast growth rates and advanced parental care of offspring have enabled it to establish oustide its native range. Laboratory intraspecific behavioural studies have shown that H. cyanoguttatus is aggressive as an invader into the territory of heterospecifics, and also as a territorial holder or resident (Turner, 1994, Draud et al., 2004). 432 pp. Rio Grande Cichlid is known for its cream and turquoise spots giving them a speckled look over a very dark to light olive background coloration. Cichlids exhibit a wide range of body shapes. Martinez et al. Rio Grande cichlids are an invasive species that has spread throughout the metropolitan New Orleans area. However these populations may now be extirpated. Herichthys cyanoguttatus (Rio Grande cichlid); adult. H. cyanoguttatus may predate on aquatic invertebrate communities (Lorenz et al., in review). (2004) listed H. cyanoguttatus as host to the following parasites: Crassicutis cichlasomae, Centrocestus formosanus, Clinostomum complanatum, Diplostomum sp., Posthodiplostomum minimum, Bothriocephalus acheilognathi, Neoechinorhynchus golvani, Rhabdochona kidderi and Contracaecum sp. H. cyanoguttatus is used by San Antonio River Authority biologists as an indicator of unbalanced or stressed ecosystems as it is pollution tolerant (Gonzales and Moran, 2005). The San Gabriel River, in the Brazos River system, contains the state's northernmost established population (Hubbs et al., 1991). Unlike tilapia and most sunfishes, which typically have three spines on the anal fin, Rio Grande cichlids are equipped with five to six anal fin spines. Parental care of offspring exhibited by cichlid fishes greatly increases offspring survival rates. They have been observed to spawn there in salinities as high as 8 psu (OT Lorenz, Georgia Southwestern State University, USA, personal communication, 2015). A revision of the fishes of the American cichlid genus Cichlosoma and of the allied genera, 7. The current status of these populations is unknown. In reviewing the systematics of these fishes in MPxico, we have encountered two undescribed Atlantic-slope species that inhabit the upper Rio … Breeding habits of Herichthys cyanoguttatus Baird and Girard. The Rio Grande Cichlid (Cichlasoma cyanoguttatum) is a moderately sized species of freshwater fish that occurs in the Rio Grande and Pecos River basins of west central Texas. Courtenay WR Jr; Hensley DA, 1979. There are reports that H. cyanoguttatus may have been accidentally introduced from resident ornamental fish farms in Hillsborough County, Florida, USA, in the 1940s and 1950s due to flooding (Courtenay and Hensley, 1979; Conkel, 1993). These research findings are supported by Lorenz (2008) and Lorenz et al. Texas Cichlid (Rio Grande Cichlid) I'm just curious if anyone has heard of these fish, or owned any, and if they are still seen in the hobby, how rare are they, etc.. Before taking a 25 year break from the hobby, I had a pair of these from a fish store in Texas. Rio Grande cichlid . Buchanan TM, 1971. They love nibbling on legs and toes. The temperature tolerance of H. cyanoguttatus goes below 7°C in outdoor artificial ponds and it can be active at 10°C (Lorenz, unpublished data). it is a human commensal), Highly likely to be transported internationally deliberately, Sport (hunting, shooting, fishing, racing), Meat/fat/offal/blood/bone (whole, cut, fresh, frozen, canned, cured, processed or smoked). These fish may grow to exceed 10 inches in length. Cichlids may be distinguished from centrarchids by the single nostril opening on each side of the head (compared with two openings in centrarchids) and the presence of a discontinuous or two-part lateral line (continuous in centrarchids) (Itzkowitz and Nyby, 1982; Nico et al., 2015). Journal of Fish Biology, 59(6):1544-1555. Both parents are active in guarding the eggs and fry though the male and female alternate in the performance of parental responsibilities. Fly fishing for Rio Grande Cichlids AKA Texas Cichlids on the Gila River in Phoenix, Arizona. A new cichlid from the Rio Balsas system, Mexico (Pisces, Teleostei). Rio Grande leopard frogs may breed all year round with warm temperatures and sufficient rainfall. (2011) who conducted interspecific behavioural experiments to examine potential agonistic interactions between H. cyanoguttatus and the US native centrarchid bluegill Lepomis macrochirus. Shafland PL; Pestrak JM, 1982. The internationally preferred common name of H. cyanoguttatus is the Rio Grande cichlid, though the species is commonly referred to in aquarium literature as the Texas cichlid (e.g. CABI Compendium: Status inferred from regional distribution. These authors concluded that these behaviours may suggest a mechanism for the continued range expansion of H. cyanoguttatus in Louisiana, USA. In: Atlas of North American freshwater fishes [ed.
