Grand Rapids, MI – Whether commercial fish farms will be allowed operate on Michigan’s Great Lakes waters is a question far from being answered, but state officials say it is being considered. A Blue-Ribbon scientific advisory panel was established in early June to study the questions involved.
Two private companies approached the state of Michigan in 2014 with proposals to grow millions of pounds of rainbow trout in floating pens. Neither has submitted an application for a permit, but state officials say the inquiries kick-started the scientific review of potential downsides and issues. A final report with recommendations is expected in October 2015.
“The science panel is looking strictly at cage-culture, not the overall aquaculture industry” said Ed Eisch, the Michigan Department of Natural Resources Fish Production Manager and agency representative to the state’s Quality of Life Aquaculture Work Group which includes the Michigan Departments of Environmental Quality and Agriculture & Rural Development.
Cage culture, he explained, involves raising fish for market in large, floating net pens in open waters – a practice not currently used in Michigan, though it is allowed by Ontario in the North Channel and Georgian Bay waters of Lake Huron. Other fish farming methods either use self-contained systems where nothing leaves a facility, or flow-through systems like those at state hatcheries.
“A well-run and designed flow-through system is of relatively low concern to me,” said Eisch, who oversees Michigan’s hatcheries. “That’s what our facilities are. But the cages have more questions marks, for sure, because everything is happening right in the Great Lakes.” Continue reading
