Lake invaders

This documentary tells the history of exotic species invasions in Lake Huron and describes other invaders looming on the horizon. Biologists from around the Great Lakes describe the invaders, the damage they have caused, and efforts to manage Lake Huron's ecosystem and multi-million dollar fisheries. The film crew also followed DNR biologists out on the lake for their annual survey of fish populations. The result is a mix of good news and bad news, but the main concern is preventing another wave of invasions through Great Lakes shipping channels. Cf. lakeinvaders.com/Lake_Invaders.html
