| Impact Description | Chinook salmon (Oncorhynchus tshawytscha) were introduced to control alewife populations in the 1960s. Since then, some agencies in Lakes Michigan and Ontario have drastically reduced their stocking quotas for Chinook salmon and are now concerned about their impact on declining populations of alewife. |
