The University of Maine Aquaculture Research Institute has been awarded $2.25 million per year of funding for recirculating aquaculture systems research.

The funding was awarded by the United States Department of Agriculture Agricultural Research Service(USDA-ARS), and supports studies Aquaculture Research Institute (ARI) scientists will conduct at the National Cold Water Marine Aquaculture Center.

Recirculating aquaculture systems (RASs) represent an increasingly important technology in the field of aquaculture. These land-based culture systems not only boost production and strengthen domestic aquaculture, but also reduce dependence on coastal ecosystems and enhance resilience to changing environmental conditions.

With innovative research and effective management, RAS operations have the potential to revolutionise the way we think about sustainable aquaculture.

This new funding will help establish ARI as a nationally recognised RAS research facility, focusing on shellfish and finfish species. Prioritised research includes the development of domestic broodstock, sustainable alternative feeds, the impacts of climate change, innovations in waste processing, reduction of environmental impacts, elimination of off-flavour compounds like geosmin and 2-methylisoborneol (MIB), and overall more energy efficient systems at The University of Maine’s Center for Cooperative Aquaculture (CCAR).

“We’re committed to expanding our knowledge and expertise in RAS to culture fish and shellfish in a way that’s productive and profitable, while ensuring the highest standards of animal wellbeing. The goal here is to optimise production, efficiency and sustainability,” explained Deborah Bouchard, director of the ARI, in a press release.

This $2.25 million in funding represents a significant investment not only for the future of the RAS industry but for workforce development as well. Several new full-time positions have been created through both ARI and USDA-ARS, enhancing infrastructure at CCAR and expanding the facility’s capabilities for cutting-edge research and development.

“This will allow ARI and USDA to continue work on improving Atlantic salmon reproductive inefficiencies. Low eye-up rates have plagued the salmon industry for the past 15 years. A new reproductive physiologist will be hired that will address these inefficiencies. In addition, a new fisheries biologist will be hired that will address off-flavour and water quality as it relates to salmon grown in RAS,” concluded Brian Peterson, director of the National Cold Water Marine Aquaculture Center.
