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.

Common name: banded tilapia

Taxonomy: available through www.itis.gov

Identification: In general, cichlids (Cichlidae) are superficially similar to sunfishes and black basses (Lepomis and Micropterus; family Centrarchidae). Cichlids can be distinguished from centrarchids by a single nostril opening on each side of the head (vs. two openings in centrarchids) and the presence of a discontinuous or two-part lateral line (vs. a continuous lateral line in centrarchids). Distinguishing characteristics of banded tilapia were given in Thys van den Audenaerde 1964, de Moor and Bruton (1988), Eccles (1992), and Skelton (1993). This species is included in keys of Skelton (1993). It was illustrated in de Moor and Bruton (1988) and in Eccles (1992). For color illustrations or photographs of this fish, see Goldstein (1973), Axelrod (1993), and Skelton (1993).

Size: to 23 cm SL (Skelton 1993).

Native Range: Tropical and subtropical Africa: Kasai drainage including the Lulua and Kwango (middle Congo River basin), upper Congo River basin including the upper Lualaba, Luvua, Lake Mweru, Luapula, Lufira, and Upemba region (Thys van den Audenaerde 1964), upper Cuanza, Cunene, Okavango, Lake Ngami, Limpopo, Sabi, Lundi, northern tributaries of the Orange River, and Bangweulu (Teugels and Thys van den Audenaerde 1991), Lake Malawi, and Zambezi system (Skelton 1993); distribution map provided in Philippart and Ruwet (1982).

Ecological

The impacts of this species are currently unknown, as no studies have been done to determine how it has affected ecosystems in the invaded range. The absence of data does not equate to lack of effects. It does, however, mean that research is required to evaluate effects before conclusions can be made.

Remarks: In response to suggestions that T. sparrmani be introduced into California, Pelzman (1972) evaluated its life history and recommended it be placed on the prohibited list because of its potential for competition with native sport fishes. In Africa, this species has been introduced outside its native range as a forage fish for bass (de Moor and Bruton 1988). It can tolerate low temperatures of about 7°C (de Moor and Bruton 1988) and, based on its distribution in Africa, T. sparrmani may be "more restricted by high (above 32°C) than low temperatures" (Skelton 1993).

Voucher specimens: Florida (UF 56197, 56198).
