Disclaimer:

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: zebra danio

Synonyms and Other Names: Brachydanio rerio (Hamilton, 1822), zebrafish, striped danio, rerio

Taxonomy: available through www.itis.gov

Identification: Keys and distinguishing characteristics were given in Sublette et al. (1990) and Talwar and Jhingran (1991). Color photographs of live fish appeared in Axelrod et al. (1985).

Size: 4.5 cm TL.

Native Range: Tropical Asia. Pakistan, India, Bangladesh, and Nepal (Talwar and Jhingran 1991). Also reported from Myanmar (Menon 1999) and Bhutan (Petr 1999).

Means of Introduction: California (St. Amant and Hoover 1969) and Florida records probably resulted from release or escape from local fish farms. Source of New Mexico population is not known; possible aquarium release as was record from Connecticut (Whitworth 1996).

Status: Extirpated in New Mexico by 2003 (S. Platania, pers.comm); reported from California, Connecticut, and Florida.

Impact of Introduction: 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: This species is a popular aquarium fish and has been widely used in experimental and developmental research.

Voucher specimens: Florida (UF 108670).
