Aquaculture is the world’s fastest growing food production sector and it now accounts for about 50% of total seafood consumption. Most aquaculture occurs under semi-natural conditions in outdoor ponds, lagoons, or at sea, but in recent years indoor farms using sophisticated recirculating aquaculture systems (RAS) technology have been established or proposed, including two salmon farms in Maine. This course will provide knowledge and scientific understanding of the opportunities and challenges presented by intensive land-based aquaculture. Students will learn about the history and importance of aquaculture as a food production system, globally and in Maine. Salmon aquaculture here and abroad will be the focus, but other species will also be discussed. Students will learn salmon biology and life history, and how the nutritional and health needs of salmon are met under culture. All aspects of recirculating aquaculture systems will be discussed, including water use and treatment, waste management, and regulatory issues. Information will be provided in the larger context of the social acceptance and environmental sustainability of intensive aquaculture.

Steve Eddy and Melissa Malmstedt are the course instructors. Both work for the University of Maine’s Center for Cooperative Aquaculture Research (CCAR). Steve began his career working in the commercial fishing sector in the Bering Sea, and then as a fisheries biologist with the National Marine Fisheries Service in Washington State studying marine pollution. In 1995 Steve moved to New Hampshire and helped establish the first commercial marine fish hatchery in the Northeast. In 2000, he began working as the Center Biologist at the CCAR, and in 2015 he became Director of the facility. Melissa worked at a remote salmon hatchery in Alaska for two years before joining the CCAR in 2012 as a Research Assistant. Melissa is now Education and Outreach Coordinator for the facility.
