Gooseneck Barnacles are a delicacy in Spain and Portugal and a species harvested for subsistence or commercial fishing across their global range. They are ubiquitous on the Oregon coastline and grow in dense aggregation in the intertidal zone. Reproductive biology of the species makes them particularly susceptible to overfishing, and in the interest of sustainability, aquaculture was explored as one option to supply a commercial product without impacting local ecological communities. A novel aquaculture system was developed and tested that caters to the unique feeding behavior of Pollicipes polymerus. Modified feeds of bio-enhanced rotifers and a blend of up-cycled commercial fish byproduct were administered to barnacles of three different size classes. Growth and propagule potential were tracked in the culture tanks. In addition, a separate experiment was performed to investigate various biometrics associated with feed efficiencies and nutritive content to assess the overall sustainability of this aquaculture system.
