Several shipments of "C. albula" eggs were received between 1884 and 1886 (Smiley 1885b; Baird 1889; Bean 1892a). Some, or all, of these fish were likely C. wartmanni, especially those that were derived from hatcheries on Lake Constance (Todd 1983). Thousands of hatched young from these eggs were stocked in Heart Pond and Lake Hebron, Maine (Smiley 1885; Baird 1889; Bean 1892; Todd 1983). Kendall (1914a) referred to the stocking of "C. albula" in Maine under the name Leucichthys albula.

† Populations may not be currently present.
Means of Introduction: Coregonus wartmanni, or a related species, was intentionally stocked as a food fish. Shipments were imported by the U.S. Fish Commission from Germany in the 1880s (Todd 1983).
Status: The introductions in Maine failed (Kendall 1914).
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.
