Cichlasoma octofasciatum   (Regan 1903)

Common Name: Jack Dempsey

Synonyms and Other Names: mojarra castarrica

Taxonomy: available through ITIS logo

Identification: Synonyms are Cichlasoma bifasciatum and C. hedricki. The species is included in identification keys of Greenfield and Thomerson (1997). For distinguishing characteristics and figure see Page and Burr (1991). Color photographs appeared in Konings (1989) and in Conkel (1993).

Size: 25 cm.

Native Range: Tropical America. Atlantic Slope drainages in Middle America from Río Paso San Juan, Veracruz, Mexico, south to the Río Ulua basin in Honduras (Greenfield and Thomerson 1997).

Nonindigenous Occurrences: Three specimens were taken from Lafayette Creek, Contra Costa County, California, in 1986 (A. J. Cordone, personal communication). Specimens 6-15 cm long have been taken from major drainages in Connecticut (Whitworth 1996). This species has been found in several canals, ditches, and quarry ponds in various parts of Florida in Dade, Palm Beach, Hillsborough, Levy, and Brevard counties, as well as an isolated population in Alachua county (Courtenay et al. 1974; Hogg 1976a, 1976b; Courtenay and Hensley 1979a; Levine et al. 1979; Dial and Wainright 1983; Gilmore et al. 1983; Jennings 1986; J. D. Williams, personal observation). Courtenay et al. (1974) reported established populations near fish farms west of Lantana, Palm Beach County, but the species was not found during a 1978 survey (Courtenay and Hensley 1979a). Northernmost population is on the University of Florida campus in Gainesville, Florida. An isolated population formerly in a rock pit in southern Levy County was eradicated in 1977 (Levine et al. 1979; Courtenay and Hensley 1979a).  This species is also established on the island of Oahu, Hawaii (Devick 1991).

Means of Introduction:

Status: Established in Florida; reported from California and Connecticut.

Impact of Introduction: The omnivorous, opportunistic feeding behavior of the Jack Dempsey should enhance its survival in areas where it is introduced (Jennings 1986). 

Remarks: Juvenile fish from the vicinities of Gibsonton, Riverview, and Ruskin in Hillsborough County, identified as Cichlasoma cyanoguttatum by Buntz and Chapman (1970), were actually this species (Courtenay et al. 1974). This highly aggressive and combative species possibly competes with native sunfishes for food and spawning sites. The population in Alachua County, the northernmost record for Florida, has persisted for more than 10 years.
