TRAVERSE CITY, Mich. — October 30, 2015 — If Michigan allows commercial fish farming in the Great Lakes, the industry should begin on a small and experimental scale to enable careful monitoring of the effect on the environment and wild fish populations, scientists said in a report to state officials.
The recommendation was among many in five reports submitted by a panel of scientists, economists and other experts appointed to advise regulators considering whether a process known as “net-pen aquaculture” would be suitable for Great Lakes waters within Michigan’s boundaries.
The state departments of Environmental Quality, Natural Resources and Agriculture and Rural Development requested the study and recently posted the reports online.
State officials say they’ve heard from two operators interested in raising rainbow trout in floating enclosures in Lake Michigan and Lake Huron. The fish would remain inside the large nets until big enough for the consumer food market. But no permit applications have been submitted.
