INAT works to build strong interactions with local and international industry and organisations. The Ecosystems Research and Aquatic Resources Unit focuses on the study of aquatic environments as well as coastal areas. This Unit takes a multidisciplinary approach, which considers both the eco-biological characterization of living resources, analysing their relationship with the environment, and their use in aquaculture. It seeks to balance conservation of ecosystems with sustainable fisheries and aquaculture. The research activities revolve around three main themes: Coastal Resources and Environment, Bio-ecology of inland waters, Aquaculture and product promotion.
