Several State agencies are looking at proposals to allow commercial net-pen aquaculture on the Great Lakes. Net-pen aquaculture is named for the offshore floating enclosures where large numbers of fish are contained and raised. The practice is controversial because of environmental concerns. WDET’s Amy Miller spoke with Tammy Newcomb; Senior Policy Advisor for the Department of Natural Resources. She says Ontario has allowed a few net-pens near Georgian Bay and now there are two Michigan proposals. This week the State is holding two public hearings on the two Great Lakes net-pen aquaculture proposals.
