Annual plants of spring fingerlings between 19 averaged approximately 350,000 in Michigan, 509,000 in Minnesota, 384,000 in Wisconsin, and 300,000 in Ontario. This introduction was extended to Minnesota in 1974, Wisconsin in 1977, and Ontario in 1988.

Chinook salmon was first planted into Lake Superior in 1967 by the state of Michigan. The first stocking of large numbers of Chinook salmon in the Great Lakes occurred in 1967 in Lake Michigan and Lake Superior in part to control alewfie. Parsons (1973) give detailed accounts of stockings in the Great Lakes. Stocking began as early as 1874 in several states. Means of Introduction: Authorized introductions for sportfishing.
