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: Authorized stockings took place in the 1930s and 1940s. The stocking in Idaho took place in 1939 (Linder 1963). The stocking in Maine took place in 1938 (Everhart 1950). The Michigan stocking occurred in 1945 (Emery 1985).

Status: Stocking attempts failed to generate reproducing populations.

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: There is some question concerning the identity of the salmon stocked into Michigan. Emery (1985) reported that they may have been misidentified chinook or coho salmon. Parsons (1973) made no mention of this species being stocked in the Great Lakes.
