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: The Ohrid trout was brought into the United States by the U.S. Fish and Wildlife Service and shipped to a federal hatchery in Iowa and a state hatchery in Minnesota (Courtenay and Hensley 1979a). In 1965, eggs from Yugoslavia were hatched in the United States; young fish were released into several small lakes in northern Minnesota in 1968 and 1969 (Stroud 1969). Ohrid trout have been stocked in Tennessee since 1971 (Etnier and Starnes 1993). The species was first stocked in Colorado in 1969 (Wiltzius 1985).

Status: Introductions into most of these states failed. Repeatedly stocked in Tennessee with no evidence of reproduction yet (Etnier and Starnes 1993). Courtenay and Hensley (1979a) report that even though there has been no reproduction, spawning has been observed in Tennessee.

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: A state record-sized fish was taken from the North Platte River in Wyoming in 1986 (Wyoming Game and Fish, Fish Division 1997).
