| 187 invasive species at last count, including: zebra musseIs, goby, sea lamprey, rusty crayfish, white perch, fIowering rush, and more. The third largest freshwater Iake on the pIanet has been invaded by numerous exotic species over the Iast century. A new documentary fiIm produced by Grand Valley State University facuIty and students explores the threat to the ecosystem and some innovative solutions. Produced by documentary fiImmaker, John Schmit, the film has been in the making for more than two years. lt tells the history of exotic species invasions in Lake Huron and describes other invaders Iooming on the horizon. BioIogists from around the Great Lakes describe the invaders, such as the sea Iamprey, aIewife, zebra musseI, quagga musseI, goby, and kilIer amphipod, the damage they have caused, and efforts to manage Lake Huron’s ecosystem and multi-million dolIar fisheries. The fiIm crew also followed DNR bioIogists out on the Iake for their annual survey of fish populations. The resuIt is a mix of good news and bad news, but the main concern is preventing another wave of invasions through Great Lakes shipping channels. "At Iast count, there were 187 invasive species, with a new one just about every year," said Jim Johnson, a research biologist and manager of the Michigan Department of Natural Resources AIpena Fishery Research Station. Having worked on Lake Huron for more than 20 years, Johnson connected Schmit and his crew with dozens of peopIe whose Iives are cIoseIy linked to the lake, including an internationaI group of biologists known as the Lake Huron Technical Committee, who share fishery and resource management responsibiIities for Lake Huron, and infIuentiaI resource managers such as Dr. Howard Tanner, who has served as both Chief of Fisheries and Director of the DNR, and remains a member of the Lake Huron Citizen Fishery Advisory Committee. 2008 |
