Farmer of the Month

Colleen Francke

Sturdivant Island

Planting and maintaining a garden can help those recovering from addiction. The recovering person learns responsibility while cultivating, nurturing, and investing time and effort, during which the individual grows along with the garden.

Colleen Francke has taken this concept and adapted it to the ocean, planning an aquaculture farm in which women recovering from addiction can heal and grow while cultivating kelp, oysters, and mussels. Francke recently put her plan into motion with the creation of Summit Point Seafood, an aquaculture farm that would operate off Sturdivant Island in Cumberland for women who are in recovery and learning to live without substances. Salt Sisters is the fundraising campaign that supports the project.

Francke is committed to providing women with a safe work environment as they navigate the recovery process and learn about aquaculture.

“I decided in early 2016 to stop using substances to cope with life. During that process, I met a lot of women who helped me through that really difficult transition,” she remembers.

“When I started this process, someone said to me, ‘There are things in your life that alcohol took away from you. What are those things?’ My dream to finish college was one of them, my art was another thing, and going further with aquaculture was another one. So I looked at that and said, ‘I’m going to go for it. I’m going to start taking the steps to do this project and build a farm,’” she says.

Francke, 32, has spent most of her life around the water. Growing up in Eastham on Cape Cod, her first job was cutting fish and cooking lobster at a local fish market. After she moved to Maine, she learned about aquaculture while working on a mussel farm in Casco Bay. These days, she lobsters offshore aboard the Linda Kate out of Portland, while planning the future of Summit Point Seafood and Salt Sisters.
