Seatone supported NOAA Fisheries, the Atlantic States Marine Fisheries Commission and a steering committee of academic experts and practitioners to design and facilitate a national workshop on artificial reefs in US waters. The workshop brought together planners, resource managers, scientists and fishermen from around the country to assess the current state of science and determine the effectiveness and efficacy of artificial reefs as a fishery management planning tool. Seatone conducted a pre-workshop survey of participant views and perspectives, and then utilized results with the steering committee to design the workshop agenda, identify guest speakers and then facilitate all elements of the two-day workshop in the Washington D.C. area. Seatone also researched state programs and current artificial reef science, and then prepared a participant workbook as a resource tool for all attendees. Seatone prepared a workshop summary which provides a detailed description of the outputs generated from this national event.
