African Jewelfish in a Breder trap Previous PSRP fish monitoring efforts were complicated by the recent invasion of this region by African Jewelfish ( Hemichromis letourneuxi ), an invasive nonnative fish that has become ubiquitous throughout much of South Florida. The following description was compiled using Page and Burr (1991), Loiselle (1992), Loftus et al. 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). During reproduction both sexes will intensify in colour and a spawning site will be chosen; usually a flat rock. A complete guide to the freshwater fishes of southern Africa. 7 pp. In the Philippines, it is unclear whether the document referenced by Froese and Pauly (2016), refers to established nonindigenous populations and/or the presence of the species within the country (for example, present within the ornamental fish trade). Zeitschrift fu?r zoologische Systematik und Evolutionsforschung, 3:277-283. Journal of Natural History, 28:937-970. Lifespan is about 5 years. Shafland and Pestrak (1982) also investigated the cold tolerance of H. letourneuxi in laboratory conditions by decreasing water temperature 1°C day, from a baseline of 21°C. Native of Africa introduced to Florida in the early 1960s. Journal of East African Natural History, 92:11-47. depth) and deep (> 80- … Of particular note is that H. letourneuxi is highly tolerant of hypoxia and high salinities.

CABI, Undated. While breeding, males may develop red colouration on the gills and ventral surface. H.letourneuxi was first documented in south Florida in the Hialeah Canal-Miami River Canal System, Miami area (Rivas, 1965) and prior to 1972 the species was only found in this localized area, i.e. 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. Recently, African jewelfish (Hemichromis letourneuxi) have invaded wetlands in a hydrologically altered agricultural landscape at Archbold Biological Station in peninsular Florida. Baber MJ; Childers DL; Babbitt KJ; Anderson DH, 2002. Nonetheless, as the status of H. letourneuxi in the Philippines is unclear, the Froese and Pauly (2016) reference is considered unreliable.

Bulletin of the Florida State Museum of Biological Science, 31(4):255. The African jewelfish is a member of the cichlid and tilapia family. H. letourneuxi, is a small, popular ornamental freshwater fish from Africa that has become established in aquatic habitats in Florida and Hawaii, Puerto Rico. H.letourneuxi is a small fish with a fairly long, slender body with a rounded caudal fin. http://rd.springer.com/article/10.1007/s13157-012-0362-0. Start studying Florida Exotic Freshwater Fish (part 1). Much like the African jewelfish the swamp eel has similar feeding habits as many fish in the Everglades, which causes over competition for their food source and causes native species to die out from not having enough food to go around. An annotated key to the genus Hemichromis Peters 1958. Fish community responses to the combined effects of decreased hydroperiod and nonnative fish invasions in a karst wetland: are Everglades solution holes sinks for native fishes? The potential for the release of H. letourneuxi is correlated with the popularity of it and its abundance among fish hobbyists. It is present along the Gulf Coast of Florida in Charlotte Harbor and in the lower Caloosahatchee, Peace and Alafia rivers (USGS NAS, 2016). Marine and Freshwater Research, 61(6):682-694. http://www.publish.csiro.au/nid/126.htm.

I monitored assemblages of fish across time in experimental mesocosms and solution holes and quantified survivorship and body condition of both natives and nonnatives. However, their study also concluded that, contrary to the effects of predatory fish introductions in other freshwater communities, they observed little evidence for a negative effect of exotic fish, including H. letourneuxi, on native organisms using a correlational approach (O’Connor and Rothermel, 2013). Over half (57%) of females were gravid and the rest were sub gravid (carried unfertilized eggs that were less developed than in gravid females). Final report from USGS to Everglades National Park for Agreement # CESI IA F5284-04-0039. Six fish (95-100 mm total length) reduced feeding at 16.8°C (range 16-17°C), ceased feeding at 13.5°C (range 13-15°C), lost equilibrium at 11.5°C (11-12°C) and died at 9.5°C (range 9-10°C).

According to Loiselle (1992), one of the external diagnostic traits of H. letourneuxi, the blue spangling, is “…sparse in males and virtually absent in females…”. (2012) in the Everglades National Park (ENP) found that populations from the invasion front (western ENP) had higher reproductive investment than inner populations (eastern ENP).

Webb AC, 2007. Additionally, in controlled mesocosm experiments, H. letourneuxi nearly eliminated populations of native shrimps and snails (Schofield et al. Gill T, 1862. 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.

Froese and Pauly (2016) also list introduced populations of H. bimaculatus as present within the Philippines and provide the collection information as “Introduced in the 1970's. The species attributed to the genus and the morphological attributes of species included in the genus, were modified by Gill (1862), Boulenger (1915), Burchard and Wickler (1965) and Payne and Trewavas (1976). Although the species grows to 12 cm standard length, the average size is much smaller, approximately 7 cm. Posthurricane recovery of riverine fauna reflected in the diet of an apex predator.

TropWater, 2016. African jewelfish, Hemichromis letourneuxi, were also collected from Starke Lake, which represents the northernmost collection of this species in Florida. Detailed coverage of invasive species threatening livelihoods and the environment worldwide. Loiselle (1979) did not include a species key and subsequently Loiselle published a key to the genus that specifically addressed identification of living and preserved specimens and thus was of use to aquarists as well as scientific researchers (Loiselle, 1992).

The acute response to changes in salinity was also tested; all fish transferred directly from freshwater to salinities up to 20 ppt survived, only 56% survived when transferred to 25 ppt and none survived transfer above 25 ppt (Langston et al., 2010).

Prior to 1972, found only in Miami Canal and canals on western side of Miami International Airport (Hogg 1976a). Species of Hemichromis are difficult to discern, in part due to wide variation in colouration within species as well as small meristic and morphological differences between species. Florida Scientist, 76(2):166-190. In the 1970s H. letourneuxi became abundant in many canals in and around the Miami/Homestead area (Courtenay et al., 1974; Hogg, 1976; Loftus and Kushlan, 1987) and in the late 1990s and early 2000s the species was found in the Everglades National Park and Big Cypress National Preserve (Kline et al., 2014; Zokan et al., 2015; USGS NAS, 2016).

The invasion of the African Jewelfish in Everglades National Park provides an opportunity to test life-history trait variation, boldness and dispersal behavior in the invasion success of this species. 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. African jewelfish Hemichromis letourneuxi Sauvage, 1880 .

H. letourneuxi, is a small, popular ornamental freshwater fish from Africa that has become established in aquatic habitats in Florida and Hawaii, Puerto Rico. 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. The small-bodied (75–100 mm TL) African jewelfish (Cichlidae) was first introduced near Miami, Florida in the early 1960s (Rivas 1965) with reports from the Tampa Bay region in west-central Florida since 1974 (Courtenay et al.
