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.

Means of Introduction: Intentionally stocked, most likely as a sport fish. According to Brock (1960), a shipment of 43 specimens was brought to Hawaii from Guam in 1957 and held in laboratory tanks; a second shipment, containing 170 fish, was received in 1958. Specimens from the second shipment were subsequently stocked.

Status: Did not survive; extirpated.

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 angling fish in Australia (Allen 1991). It inhabits mainly fast-flowing clear coastal streams, but sometimes travels 200-300 km inland in large rivers (Allen 1991). A second species, K. sandvicensis, is endemic to marine and lower stream habitats of Hawaii (Devick 1991).
