the grower

Jim O'Shea has been growing oysters since 2012. After earning a degree in Marine Biology from Northeastern University, Jim realized he wanted to work outdoors and be by the ocean instead of sitting at a desk. He has been harvesting seaweed over the last 25 years, but got involved in oyster aquaculture after convincing the Plymouth harbormaster to allow him to experiment with a lease site.

"Growing oysters is more fulfilling. I enjoy feeding our local community and being a part of the farm-to-table movement. It's a way of life here."

Jim and his daughter, Ina, work and manage the farm full-time. They are harvesting more each season and are excited to see their oysters go to market.
