The Institute of Aquaculture is open for Transnational Access (TNA) to our aquaculture research infrastructure though the EU funded AQUAEXCEL3 programme. The Institute participated in the first (AQUAEXCEL, 2011-2015) and the second (AQUAEXCEL2020, 2015-2020) of these initiatives to provide access to leading aquaculture research infrastructures. We hosted nine TNA projects in the first AQUAEXCEL programme and ten in the second. Within AQUAEXCEL3 (2020-2025) we expect to host around 14 projects, usually involving one visitor spending an average of 7 weeks at the Institute of Aquaculture. This site provides information for potential and current users of the IoA infrastructure and news about the research that is supported here.
