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.

Cichla ocellaris Bloch and Schneider, 1801

Common name: Butterfly Peacock Bass

Synonyms and Other Names: pavón, tucunaré, tuc, peacock bass, butterfly peacock, tucunare comun, eyespot cichlid, lukanani

Taxonomy: available through www.itis.govITIS logo

Identification: Currently, systematists recognize five Cichla species; however, taxonomic problems still exist, and several species require description (Kullander and Nijssen 1989). The genus is currently being revised by Sven Kullander of Sweden. Willis et al. (2007) published results of molecular inquiry into systematic relationships within Cichla. Many fish currently called C. ocellaris by state resource agencies may be members of another Cichla species or possibly hybrids. Photographs of C. ocellaris, or of closely related forms, appeared in Kullander and Nijssen (1989), Axelrod (1993), and in Larsen (1993).

Size: 70 cm TL.

Native Range: Tropical America. Although the genus Cichla is widespread in the Amazon and Orinoco basins of South America, true Cichla ocellaris apparently is restricted to the Guianas (Kullander 1986; Kullander and Nijssen 1989).

Ecology: Members of the genus Cichla are large, diurnal piscivores that consume a wide variety of prey (Winemiller et al. 1997). Cichla ocellaris is a pair-forming substrate spawner, with spawning occurring on flat surfaces and newly hatched larvae moved by the parents to nests in small shallow depressions in the sediment or on rocks or logs (Zaret 1980)

Means of Introduction: Peacock cichlids have been stocked by state agencies as a sport fish. The Florida Game and Fresh Water Fish Commission obtained breeding stock from several regions of South America. The progeny were released into open waters primarily as a sport fish, but also with the hope that it would prey on and thus control other introduced cichlids (Courtenay and Robins 1989; Shafland 1995). About 10,000 juveniles were released in the Fort Lauderdale area of Dade County, Florida, in 1964 (Moe 1964), but apparently those fish did not survive the cold winter of 1964-1965 (Courtenay et al. 1974; Courtenay and Robins 1989). More recent introductions into canals in Broward and Miami-Dade counties, starting in late 1984, resulted in established populations (Larsen 1993; Shafland 1995). The Hawaiian Division of Fish and Game obtained their broodstock from an aquatic supply dealer in New York, ca. 1957 (Kanayama 1968). These fish reportedly came from Guyana (Larsen 1993). The first Texas populations were released by the Texas Parks and Wildlife Department in 1978. Texas stock came from Colombia and possibly Brazil, and from the Florida Game and Fresh Water Fish Commission. The single fish reported from Arizona was likely an aquarium release or illegal stocking, as no authorized stocking of this fish has occurred in that state.

Status: Established in south Florida (Courtenay and Robins 1989; Shafland 1995), Guam (Welcomme 1988), Hawaii (Maciolek 1984), and Puerto Rico (Erdman 1984). Shafland (1996) indicated that fishable populations of peacock cichlid in Florida exist in more than 500 km of canals, plus numerous urban lakes in the metropolitan Miami-Ft. Lauderdale area. The range of this species in Florida is limited by cold winters that restrict it to the southernmost counties and exclude it from much of the Everglades. Extirpated in Texas: some Cichla populations in Texas survived and reproduced for a brief period, but by 1992 all fish had died. For the most part, Cichla species are unable to survive cold winters, although evidence indicated fish in one Texas reservoir succumbed to high summer temperatures (Garrett 1982; Courtenay and Robins 1989; Howells and Garrett 1992). Unknown, but likely failed, in Arizona.

Impact of Introduction: Largely unknown. Introduced Cichla in Florida include native fishes in their diets (Nico, unpublished data) although Shafland (1999) claimed no evidence for adverse effects on native communities. There is some evidence that it may exclude largemouth bass from spawning aread in Florida canals. The introduction of peacock cichlids into Lake Gatun, Panama, was followed by largescale changes in food-web structure and aquatic community composition (Zaret and Paine 1973).
