April 15, 2025 — A recent study from the University of Maine’s Aquaculture Research Institute and Darling Marine Center is offering Maine scallop farmers practical insights into gear selection and its impact on growth and profitability.
The research published in Aquaculture and reported by the Penobscot Bay Pilot compared two common farming methods- lantern nets and ear-hanging- across a full grow-out cycle in Penobscot Bay and Frenchman Bay.
According to Science Daily, suspended culture is the most common approach, with farmers typically using multi-tiered lantern nets to grow scallops to a harvestable size. UMaine shares that ear-hanging, a technique adapted from Japanese scallop farming, offers a potential alternative. This method involves drilling a small hole in the scallop’s shell and suspending it on a line, allowing for better water flow and potentially reducing maintenance needs.
