Michigan's Aquaculture Industry Could Grow, but Concerns Remain


US - Michigan has the capacity to support a much larger aquaculture industry compared to what now exists, according to an integrated assessment project from Michigan Sea Grant and Michigan State University Extension.

On a global scale, aquaculture has grown tremendously in recent decades to meet half of the world’s seafood demand. In contrast, commercial aquaculture development in Michigan has been stagnant for decades.

The integrated assessment project has shown that Michigan can expand its aquaculture operations. Reasons for this include Michigan’s abundant water supply, affordable real estate, a need for new economic opportunities, existing expertise in fisheries, and existing agriculture and food processing capacity.

As a result of the project, aquaculture stakeholders in Michigan identified Great Lakes net pen aquaculture as a segment for development that should be explored.

Great Lakes net pen aquaculture is not without controversy as it would involve the farming of fish in the public waters of the Great Lakes. A full day public forum coordinated by Originz was recently held to exchange dialogue over open water fish production in the Great Lakes.

A variety of stakeholder groups from Michigan participated in this event to initiate public discussion on how Michigan’s water resources can best be utilised for society’s benefit to deliver fresh, healthy and affordable seafood.

Topics that were discussed by stakeholders who were both for and against Great Lakes net pen aquaculture included fish feeds and waste, fish health and antibiotics, types of aquaculture production systems and siting, genetics, and ecosystem and socio-economic impacts.

Michigan Sea Grant Extension staff participated in this event and discussed how Seafood HACCP (Hazard Analysis and Critical Control Point) can be implemented to address the use of antibiotics in fish. The state of Michigan has also convened a panel of experts to address the topic of Great Lakes net pen aquaculture and should have a report available sometime this fall.
