New and little-known reptiles and fishes in the museum collections. Since about 1995, the Rio Grande cichlid is becoming more common in the waters in and around New Orleans. These fish may grow to exceed 10 inches in length. Lake Dunlap. http://www.seriouslyfish.com/species/herichthys-cyanoguttatus/. Publications of the Institute of Marine Science, 8:299-365. It is the only native cichlid in the U.S. and amongst the first cichlids imported to Europe, having first been imported in 1912. Robertson MS; Winemiller KO, 2003. Atlas de los helmintos parasitos de ciclidos de Mexico (Atlas helminth parasites cichlids Mexico), 27. Although breeding pairs will attack most other fishes in the vicinity of the nest, attacks are more pronounced against conspecifics. (2002) found that H. cyanoguttatus was host to many parasitic infestations (protozoa, worms, etc.) Lorenz (2008) confirmed that H. cyanoguttatus will occur in elevated salinities in estuarine conditions in Lake Pontchartrain in New Orleans. Molecular Phylogenetics and Evolution, 31(2):754-764. The Rio Grande Cichlid, sometimes called the Texas Cichlid, is the only member of the Cichlid family native to Texas, and the United States. Courtenay WR Jr; Sahlman HF; Miley WM, 1974. I accept Jesus Christ as my Savior ! Herichthys cyanoguttatus Baird & Girard, 1854. Lorenz (2008) stated that the species was further dispersed in bayous in the New Orleans area in Louisiana by hurricane Katrina during 2005. It has been recorded at salinities as high as 27 psu, but long-term survival (one year) was poor at 16 psu (Lorenze, unpublished data). Rio Grande cichlid . This suggests there is the potential for biotic resistance and competition in natural aquatic ecosystems to be utilized to minimize the impact and spread of H. cyanoguttatus in Louisiana, USA.

No longer present, Native to the lower Rio Grande drainage; introduced to many other areas of Texas, Introduced to the Rio Verde basin (La Media Luna region), Recorded from the Loíza Reservoir in 2006-2007, Native Texas specimens officially translocated and introduced to other drainages in Texas as early as 1928. Raleigh, NC, RC: North Carolina State Museum of Natural History,. 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. God forgive me a sinner. Regan (1905) subsumed Herichthys into the large genus Cichlasoma until Kullander (1983) restricted the latter genus to only South American cichlid species. Physiological effects of saline waters on zander. Journal of Fish Biology, 59(6):1544-1555.

In Texas, USA, the species was translocated by the US Fish and Wildlife Service in 1928 and released into waters on the Edwards Plateau, Guadalupe River drainage, between 1928 and 1941 or 1943 (Brown, 1953; Hubbs et al., 1978). Louisiana, USA: The Times-Picayune. Texas cichlids are native to lakes and rivers in south Texas and northern Mexico, making them the most northern naturally occurring species of cichlid in the world. Hubbs C, Lucier T, Garrett GP, Edwards RJ, Dean SM, Marsh E, Belk D, 1978. Fishers get chance to combat invasive species at New Orleans City Park fishing rodeo Saturday. Hernandez-Rolon A, 1990.

It can grow over 33 centimeters in length, and males can develop a protrusion known as a nuchal hump on their head. Because sample sizes were very small for females, frequency comparison between sexes was not performed. (2011) who conducted interspecific behavioural experiments to examine potential agonistic interactions between H. cyanoguttatus and the US native centrarchid bluegill Lepomis macrochirus.

Texas, USA: Texas Parks and Wildlife Department. In Louisiana, USA, they are often eaten and are popular with fly fishermen (OT Lorenz, Georgia Southwestern State University, USA, personal communication, 2015). A revision of the South American cichlid genus Cichlasoma (Teleostei: Cichlidae). Regan CT, 1905. Hubbs C, 1951. Rio Grande cichlids are an invasive species that has spread throughout the metropolitan New Orleans area. Mills and Vevers (1989) report a diet of worms, crustaceans, insects and plant matter. 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. These invasive fishes compete with sunfishes (e.g., black bass) for food and spawning areas. The further spread of H. cyanoguttatus by natural dispersal may occur in the USA. Cichlids are superficially similar to North American native sunfishes (Lepomis spp.) compared to the closely related monogamous Rio Grande cichlid, H. cyanoguttatus, males of H. minck-leyi were present at their nests less often and performed lower rates of aggressive offspring defense, and females compensated for the absence of their mates by performing higher levels of offspring defense. The size of individuals varies by species and ranges from about one inch (2.5 cm) to three feet (1 m). The Texas Cichlid Herichthys cyanoguttatus (previously Cichlasoma cyanoguttatum) is the northern most occurring cichlid and the only cichlid native to waters of the United States.It is naturally found in the waters of southern Texas ( namely the Rio Grande) and northern Mexico. Ecological Threat: Blue Tilapia have been found to negatively impact fish populations and degrade habitat. > 0°C, dry winters), Salinities of up to 16 ppt had no significant effect on growth in the laboratory therefore short/long term tolerance is likely to be higher (Lorenz, 2008), Lower lethal temperature of 5°C recorded in laboratory (Shafland and Pestrak, 1982), Herichthys cyanoguttatus Baird and Girard, 1854, Cichlasoma cyanoguttatum Baird and Girard, 1854, Herichthys cyanoguttatum Baird and Girard, 1854, Parapetenia cyanostigma Hernandez-Rolon, 1990, Highly adaptable to different environments, Capable of securing and ingesting a wide range of food, Benefits from human association (i.e. Atlas of North American freshwater fishes. The majority of introductions of the species in the USA are thought to have resulted from the release of aquarium fishes (Nico et al., 2015). Despite being known for its violent temper it attracts a lot of admirers, mainly because of its bright colors. There are several black spots at the base of the caudal fin and along the middle, rear half of the body. Fish and Wildlife Service, Gainesville, FL. Grey-brown; head, body & fins with many small, blue spots; a row of dark spots along mid-flank, typically one at mid-body, another on tail fin base, sometimes several more between those; body with up to 8 indistinct dark bars, those on rear half of body darker; no stripe along mid-side; sometimes a black spot on middle of spiny dorsal fin. Introduced fish species in the Guadalupe River Basin. Texas Parks and Wildlife call it a Rio Grande Cichlid so thats what I go by. Its main body color can be pale light brown to dark blue or almost purple and changes with its mood or during mating season. Itzkowitz M; Nyby J, 1982. Report Submitted to National Fishery Research Laboratory, U.S. The euryhalinity of H. cyanoguttatus would greatly aid the species to disperse naturally. Breeding males have a prominent nuchal hump (Page and Burr, 1991), and males are typically larger than females (Itzkowitz and Nyby, 1982). Gonzales M; Moran E, 2005. Brown JA; Moore WM; Quabius ES, 2001. Mire J, 2001. Introduced populations of H. cyanoguttatus occur in estuarine environments in the New Orleans area (Lake Pontchartrain) of Louisiana. Seriously Fish, 2015. http://blog.nola.com/new_orleans/2012/03/fishers_get_chance_to_combat_i.html. (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. Etymology/Derivation of Scientific Name. In reviewing the systematics of these fishes in MPxico, we have encountered two undescribed Atlantic-slope species that inhabit the upper Rio … dense small blue spots: head, body & fins, Soft bottom (mud/sand/gravel/beach/estuary/mangrove/seagrass), Subtropical (23-35N, Florida / Carolinas / Bermuda), Note: range polygons may be inaccurate for species known only from a few, widely scattered sites. However these populations may now be extirpated. Both Courtenay et al. The name 'red Texas cichlid' is chiefly used to describe a hybrid between H. cyanoguttatus and another cichlid species (Berg, 2010). l'he Neotropical cichlids of the genus Cichlasoma attain their max- imum number ant1 diversity in Middle America, where about 75 species are known. There is one nostril opening on each side of the head and an interrupted lateral line (Itzkowitz and Nyby, 1982) that is doubled for a short distance on the caudal peduncle (Tomelleri and Eberle, 1990). This process continued until 2500-3000 eggs had been laid and fertilized. Type Locality. Lower lethal temperatures for 14 non-native fishes in Florida. American Midland Naturalist, 108(2):364-368. The Texas Cichlid, also known as the Rio Grande Perch, and the Rio Grande Cichlid, is an iridescent golden color with pearl highlights and white dots on its body and fins. It has been reported as established in the Rio Frio, Colorado, San Antonio, San Marcos, Guadalupe and Comal rivers in the Edwards Plateau region (Brown 1953; Hubbs et al., 1978; Nico et al., 2015). Mexico: Instituto Politecnico Nacional, 06040. Buchanan TM, 1971. Salgado-Maldonado et al. Stockholm, Sweden: Naturhistoriska Riksmuseet. Potential ecological impacts upon endemic fish fauna may include resource competition and predation, and predation of aquatic invertebrate communities. by Malabarba LR, Reis RE, Vari RP, Lucena ZM, Lucena CAS]. Fishes of the Central United States. > 10°C, Cold average temp. Martinez VMV; Macedo MLA; Scholz T; Solis DG; Franco EFM, 2002. H. cyanoguttatus is a moderately popular ornamental fish species maintained by hobbyists worldwide. Berg, 2010; Seriously Fish, 2015). It was found that H. cyanoguttatus was highly aggressive both as a territory holder and also entering the territory of L. macrochirus indicating potential competition for space with native centrarchids. Lorenz OT, 2008. Inland Fisheries. Survival and abundance of introduced fishes near San Antonio, Texas. H. cyanoguttatus is one of the most cold-tolerant cichlids. This cichlid also prefers the water temperature to be between 68 and 82 °F (20–28 °C) and are negatively affected by rapid changes in temperature. Fish introductions in the American southwest: a case history of Roger Spring, Nevada. No longer present, Single specimen was found in a pool on the Olentangy River. The Rio Grande or Texas cichlid Herichthys cyanoguttatus is a popular ornamental freshwater fish that has been introduced to a number of US states. Detailed coverage of invasive species threatening livelihoods and the environment worldwide. John 3:16 Sinner's Prayer. Lorenz (2008) found that it was often the most common species in urban canals in the New Orleans metropolitan area. Cichlidae (Cichlids). They are also leaner in size. Cichlids exhibit a wide range of body shapes. No longer present; First reported: mid 1980s, Collected from bayous and canals in the New Orleans metropolitan area as well as isolated specimens in other areas; First reported: 1990s, Found in a reservoir south of Lincoln in the Salt River drainage. Baird SF; Girard CF, 1854. There is a black dot at the base of the caudal fin and one in the center of the body. Pair formation occurs before territory establishment and pairs will actively defend their territory to defend the eggs and fry. These little monsters are harmless, but you will freak out over them. Comment by 10.5" RES Sharon on January 22, 2011 at 9:05am Wallingford, UK: CABI. Kullander SO, 2003. Adult males also develop a nuchal hump on their head.

Fish introductions in the American southwest: a case history of Roger Spring, Nevada. H. cyanoguttatus was recorded to be established in Six Mile Creek in Hillsborough County (the population may have been extirpated since) with the source of this introduction possibly a fish farm that cultured the species as an aquarium fish during the 1940s and early 1950s under the trade name 'Texas bluespot' (Courtenay and Hensley, 1979; Nico et al., 2015). H. cyanoguttatus is a biparental substrate spawner/brooder with preferred spawning sites usually solid substrates (rocks) in shallow water (Itzkowitz and Nyby, 1982). The Southwestern Naturalist, 28(2):221-224. In contrast to Pterophyllum, however, extended finnage is absent giving Symphysodon a more rounded shape. > 10°C, Cold average temp.

There are a number of small black spots on the base of the caudal fin and alongside the middle, the rear half of the body. Fly fishing for Rio Grande Cichlids AKA Texas Cichlids on the Gila River in Phoenix, Arizona. Turner GF, 1994. When several references are cited, they may give conflicting information on the status. Rio Grande cichlid, Texas cichlid. The sides of the fish are frequently patterned in shades of green, red, brown, and blue. Draud M; Macias-Ordonez R; Verga J; Itzkowitz M, 2004. H. cyanoguttatus is captured by recreational anglers and the species is considered very palatable (Mardon, 2012; Texas Parks and Wildlife, 2015). The species matures at approximately 100 mm standard length (SL), after one year of growth (Buchanan, 1971). H. cyanoguttatus is a habitat generalist and will occupy lentic and lotic aquatic habitats including ponds, lagoons, creeks, rivers (in pools and backwaters) and springs with mixed substrate types (rocks, sand, mud, sand, clay, aquatic vegetation) (Robertson and Winemiller, 2003; Miller et al., 2005). These fish are abundant in southern Texas and northern Mexico where they are called Rio Grande perch or Texas cichlid. Nico L; Fuller P; Neilson M, 2015.
