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.

Epinephelus fasciatus (Forsskål, 1775)

Common name: blacktip grouper

Taxonomy: available through www.itis.govITIS logo

Identification: Dorsal rays XI (15-17); anal rays III (7-8), pectoral rays 18-20; lateral-line scales 49-75.  Scale counts and colouration variable within the extensive range -- at least 6 morphologically distinct populations known (Randall and Heemstra 1991; Heemstra and Randall 1993).

Size: 40.0 cm TL; max.weight: 2,000.0 g.

Native Range: Indo-Pacific from the Red Sea and western Indian Ocean to western Australia, and in the Pacfic from Japan and Korea to southern Queensland and Lord Howe Island and eastward to the Pitcairn Islands (Randall and Heemstra 1991; Heemstra and Randall 1993).

Nonindigenous Occurrences: In 1958, 51 fish from the Marquesas were stocked in marine waters off the island of Oahu, Hawaii (Maciolek 1984).  These fish failed to establish (Mundy 2005).

Ecology: Feeds on fishes and crustaceans (e.g., brachyuran crabs).  Occurs on coral reefs or rocky substrata over a variety of depths.  It is common in shallow water, but also recorded from up to 160 m. From Randall and Heemstra 1991.

Means of Introduction: Intentionally stocked.

Status: Failed.

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.
