Recent fish introductions into Everglades National Park: an unforeseen consequence of water management? [English title not available]. This has been demonstrated in Florida where, since its introduction it has rapidly expanded to inhabit aquatic habitats over much of the southern half of the Florida peninsula. Boston, USA: Houghton Mifflin Company, 432 pp. The eggs hatch in approximately 72 hours and the brood is moved into a shallow depression in the substrate near the spawning site. Canadian Journal of Fisheries and Aquatic Sciences, 59:1441-1450. Reviews in Fish Biology and Fisheries, 25(1):117-145. http://rd.springer.com/journal/11160, Schofield PJ; Loftus WF; Brown ME, 2007. The fry become free-swimming after approximately 24 hours and parental care may continue for some time while the fry grow (Seriously Fish, 2016). only in Miami Canal and canals on western side of Miami International Airport (Hogg, 1976). Percent of non-native fishes were highest at the eastern boundary of Everglades National Park and declined westward. The seasonal diet of H. letourneuxi was investigated in the Rocky Glades area of the Everglades National Park, Florida and was found to be primarily carnivorous and included small fishes, arthropods (shrimp and other crustaceans and insects) and varied according to prey availability which was mediated by seasonal water levels (Loftus et al., 2006). Final report from USGS to Everglades National Park for Agreement # CESI IA F5284-04-0039. It has a moderately compressed and fusiform body that is straw brown to tan in color with areas of red pigment and bright blue spotting.

Coral Gables, FL, USA: University of Miami, 142 pp. Species of Hemichromis available within the ornamental fish industry are prized for (i) bright red colouration covering the whole body and (ii) blue “spangling” also covering much of the body. © Copyright 2021 CAB International. American Midland Naturalist, 170(1):52-65. http://www.bioone.org/loi/amid. Payne IA; Trewavas E, 1976. In addition to this research by Lopez et al. Environmental Biology of Fishes, 7(2):149-156. Researchers have speculated that introduced populations of H. letourneuxi in Florida are the result of escapes from fish farms (USGS NAS, 2016). http://nas.er.usgs.gov/, Mark Maddern, Consultant, Perth Australia. USGS Nonindigenous Aquatic Species Database., Gainesville, Florida, USA: USGS. Florida fresh water fishes and conservation. Florida Scientist, 76(2):166-190. Cichlids can be distinguished from centrarchids by a single nostril opening on each side of the head (two openings in centrarchids) and the presence of a discontinuous or two-part lateral line (continuous line in centrarchids) (Page and Burr, 1991; USGS NAS, 2016). 2014). Cichlids (Cichlidae) are superficially similar to North American native sunfishes and black basses (Lepomis and Micropterus; family Centrarchidae) and may be confused with members of Centrarchidae in this region. Gainesville, Florida, USA: USGS. However, no further information is available regarding populations in the Philippines or Europe. (2006), Schofield et al. I monitored assemblages of fish across time in experimental mesocosms and solution holes and quantified survivorship and body condition of both natives and nonnatives. Loiselle (1979) revised the genus Hemichromis and provided diagnoses, photographs and synonyms for the species and Loiselle (1992) includes a species key utilizing morphological and meristic characteristics that allows identification of living as well as preserved specimens. > 10°C, Cold average temp.

Hemichromis letourneuxi (African jewelfish); adult. A further study by Moyer et al. A study by Lopez et al. Loiselle PV, 1979. African Jewelfish are aggressive and territorial, thus they are predicted to be more successful at acquiring space and resources, and may displace native Sunfishes. Although the species grows to 12 cm standard length, the average size is much smaller, approximately 7 cm. H. letourneuxi is tolerant of environmental variability and introduced populations in Florida have been found to be euryhaline, resistant to low dissolved oxygen (hypoxia) and low temperatures (Loftus et al., 2006).

For example, it occurs in the Charlotte Harbor Estuary, Florida (Idelberger et al., 2011). Tropical water and aquatic ecosystem research., Australia: James Cook University. In recent decades the distribution of H. letourneuxi has rapidly expanded and the species is now found across the southern half of the Florida peninsula. CABI is a registered EU trademark. Hickley P; Bailey RG, 1987. Overall, when the popularity of H. letourneuxi is considered, along with the number of countries the species has been successfully introduced to, the likelihood of further introductions is low/moderate. In Figure b above, the stars show where African jewelfish were first seen in ENP in 2000. Quarterly Journal of the Florida Academy of Science, 28(3):255-258. Schofield et al.

Low levels of predation were also recorded by Centropomus undecimalis, Lepisosteus platyrhincus, Micropterus salmoides, Lepisosteus osseus and Amia calva in the Peace River, Florida (Blewett et al., 2013). H. letourneuxi is an aggressive species, particularly during reproduction and it likely that this behavioural trait has assisted it to spread across the Florida peninsula in syntopy with other larger, aggressive cichlids (USGS NAS, 2016). Guide to the fishes of the River Nile in the Republic of the Sudan. In: European Journal of Wildlife Research, 58 (1) 243-253. Within its native range, H. letourneuxi is a savannah-associated species which prospers in a range of lentic habitats that include brackish water lagoons, large lakes and riverine flood plains. From the fish name it’s already clear that african jewel fish is a beautiful one. depth) and deep (> 80- … Species of Hemichromis are popular ornamental fish species maintained by hobbyists worldwide, although no data is available with regards to the value of H. letourneuxi. The African jewelfish is of increasing interest in fish sampling and environmental DNA Zokan M; Ellis G; Clem SE; Lorenz J; Loftus WF, 2015. Currently, there are 11 species recognised in the genus Hemichromis (Froese and Pauly, 2016). 1):S175-S187. The African Jewelfish, Hemichromis letourneuxi, is an invasive, predatory cichlid fish introduced at least once to Florida. (2014) used artificial ponds together with logistic regression models to assess the detection of H. letourneuxi eDNA at varying fish densities. (Hemichromis guttatus Gunther 1862 (Pisces: Cichlidae), Nueva Introduccion en Mexico, en Cuatro Cienegas, Coahuila. H. letourneuxi can naturally disperse itself into new locations via interconnected riverways, canals and ditches (O’Connor and Rothermel, 2013).

Although it is not invasive in Florida, guppy is easier and faster to work with than the jewlfish and may serve as a proof-of-concept species. African jewelfish, Hemichromis letourneuxi, were also collected from Starke Lake, which represents the northernmost collection of this species in Florida. Ecology of Freshwater Fish, 21(3):375-385. http://onlinelibrary.wiley.com/journal/10.1111/(ISSN)1600-0633, Rehage JS; Liston SE; Dunker KJ; Loftus WF, 2014. Further details may be available for individual references in the Distribution Table Details section which can be selected by going to Generate Report. Nonetheless, as the status of H. letourneuxi in the Philippines is unclear, the Froese and Pauly (2016) reference is considered unreliable. Data from these collections are available in the USGS Nonindigenous Aquatic Species database. 120 pp. http://nas.er.usgs.gov/. There is a dark black lateral spot above the lateral line on the side of the fish and smaller blotches on opercular tab and caudal peduncle. Taxonomy, common names and distribution of fish in the eastern arm of the Rift Valley drainage, Kenya. Sure enough, after the jewelfish, which hails from the waters of the African savannah, first appeared in canals in Miami and Hialeah in the 1960s, it headed north to Palm Beach County. Introduced fishes in short-hydroperiod wetlands: evaluation of sampling, status, and potential effects. (2011) state that H. fasciatus and H. guttatus were established in a hot spring near Austrian Villach around 1970. http://rd.springer.com/article/10.1007/s13157-012-0361-1, Rehage JS; Lopez DP; Anderson MY; Serafy JE, 2015.

Regular wet-season flooding (includingoccasional hurricanes) likely assisted in the expansion of H. letourneuxi westward through the Rocky Glades in the Everglades National Park in 2005 (Loftus et al., 2006). Recently, African jewelfish (Hemichromis letourneuxi) have invaded wetlands in a hydrologically altered agricultural landscape at Archbold Biological Station in peninsular Florida.
