Maine's working waterfront generates enormous amounts of waste — fish heads, viscera, eel trim — material that processors pay to get rid of. Liam Fisher thinks that's an opportunity hiding in plain sight.

In this episode of Rising Tides, Bill Perna speaks with Liam about the unlikely path that brought him from mechanical engineering in Worcester to hand-cutting eels on the Maine coast, and how a bucket of smelts from a roommate set him on the road to building Maine's first waste-stream fish sauce.

Trained in the fermentation traditions of fine dining and shaped by years working in aquaculture and seafood processing, Liam has developed a garum — an ancient fermented fish sauce — made entirely from byproducts that would otherwise be discarded. The product launched quietly in July and sold out its first case in a single day. Since launch, the product has found its way into restaurants and retail shops across the Maine coast, with demand already outpacing what he can currently produce.

Their conversation covers the science of fermentation, the economics of waste utilization, and what it takes to turn a passion project into a sustainable business on the Maine coast.

Maine’s coastal economy is being quietly reshaped by new industries, new pressures, and the people working to connect them. In this episode of Rising Tides, Bill Perna speaks with Dana Morse about what it really takes to support a changing working waterfront.

With decades of experience at Maine Sea Grant and the University of Maine’s Marine Extension program, Dana reflects on his role at the intersection of science, industry, and community. From helping shellfish farmers get started to advising on policy and innovation, he shares how aquaculture has evolved alongside Maine’s traditional fisheries and what that means for those making a living on the water.

Their conversation explores the realities behind diversification, the challenges of access and infrastructure, and how climate and market forces are shaping decisions on the ground. Grounded in long-term perspective and hands-on experience, this episode looks at how collaboration, adaptation, and practical support systems will define the future of Maine’s working waterfronts.

Maine’s working waterfronts are evolving, as aquaculture, climate change, and shifting access reshape how coastal communities make a living. In this episode of Rising Tides, Bill Perna speaks with Abby Barrows about her path from environmental science into oyster farming, and what that shift reveals about the future of Maine’s coast.

Abby reflects on why she chose to buy an oyster farm on Deer Isle, what makes that particular stretch of water unique, and the practical challenges of operating an aquaculture business in a region long dominated by lobstering. Their conversation explores how environmental pressures, infrastructure limitations, and waterfront access influence day-to-day decisions on the water.

Grounded in both scientific research and lived experience, this episode considers how aquaculture, diversification, and community collaboration may shape the next chapter of Maine’s working waterfronts.

Maine has abundant, sustainably managed fisheries, yet much of that fish never reaches local plates. In this episode of Rising Tides, Bill Perna speaks with Ben Martens about why disconnects between fishing, markets, and access continue to shape who benefits from Maine’s coastal resources.

Ben reflects on how working waterfront access, unstable markets, and shifting priorities affect fishing communities, even when fish stocks are healthy. Their conversation explores efforts to strengthen local food systems, connect Maine seafood to schools and communities, and think long-term about resilience in the face of environmental and economic change.

Decisions made today will shape Maine’s coast for decades to come. In this episode of Rising Tides, Bill Perna speaks with Bill Mook about how science, regulation, and long-term thinking influence the future of the working waterfront.

Bill Mook reflects on the role of research and governance in managing coastal change, from aquaculture development to broader environmental pressures in the Gulf of Maine. Their conversation explores how evidence, public process, and collaboration help guide difficult choices, and why patience and perspective matter when balancing growth, conservation, and community needs.

Maine’s coastal future is being shaped by people adapting in real time. In this opening episode of Rising Tides, Bill Perna speaks with oyster farmer Jeff Auger about the forces reshaping the working waterfront.

Jeff reflects on his path into aquaculture and the realities of building a livelihood on the water today. Together, they discuss cooperation between fishermen, farmers, regulators, and coastal communities, and how environmental change, access, and local knowledge increasingly shape everyday decisions along Maine’s coast.

Eric Oransky grew up in Freeport, Maine. He spent a lot of time on Casco Bay.  When he was 21, he apprenticed with the Scottish master cabinet maker James Bowie for furniture making in northern California. In 2007, at 23, Eric moved back to Maine and started his first business,  all the while spending time on the water any chance he got. He focused on woodworking, including furniture, and building for about seven years. He found he missed working on the water. So, in 2017 he formed Maine Ocean Farms with his two partners, Willy Leathers and Tom Klondenski.
