But under water, it is largely a man-made production....Its salmon are saltwater predators that begin life in Midwest hatcheries and are typically unable to reproduce on their own. They are born to be caught. About 13 million exotic salmon and trout are planted yearly, creating what retired Wisconsin Department of Natural Resources fishery chief Lee Kernen calls a 'sportsman's paradise.' But today, it is a paradise imperiled. This year [2005] the salmon were biting on just about anything, and commercial fisherman Dennis Hickey says he knows why: They are starving." (MILWAUKEE JOURNAL SENTINEL) This article provides an overview of how "Lake Michigan has been engineered into a system focused on producing a maximum amount of sport fish, most of which are not native to its waters," noting that mounting evidence suggests "the lake could be on the brink of 'ecosystem shock,' a food chain collapse caused by a non-stop invasion of foreign species."| Item type | Current location | Call number | Status | Date due |
