Restoring fish populations leads to tough choice for Great L...(ng since 1980. Although multiple factor...)

ng since 1980. Although multiple factors may be at play, predation by piscivorous fish appears to be the one factor that was universally important across all five Great Lakes because of massive fish stocking. The stocking was done to create recreational activities, and to reduce populations of exotic prey fish in the hope of restoring populations of native fishes.

The effects on other species that are more closely tied to the water, such as terns, may be more severe, says Hebert. Those kinds of birds can only eat fish, so their diet may be affected by this, too. They dont have the option of eating food found on land.
