In September 2015, the first agri benchmark workshop on Fish took place at the Thünen Institute of Fisheries Ecology and the Thünen Institute of Sea Fisheries in Hamburg.

Following two years of research, the workshop participants discussed the results of a trout pilot study. 20 researchers and fish farmers from Europe, the Near and Middle East compared country reports and datasets of trout farms from different countries.

The group also visited two nearby trout farms at the Luneburg Heath. On site, potentials and drawbacks of organic fish farming and recirculated aquaculture systems were discussed with farm managers.
