From November 10 to November 12, 2021, I visited the Hellenic Agricultural Organization - Demeter for the ongoing AquaTech4Feed project. The discussion took place with project participants from the University of Malta, Istituto Sperimentale Italiano (Lazzaro Spallanzani), Bantry Marine Research Station, Leibniz-Institut für Agrartechnik, University of Almeria, Teagasc a G-FISH. This cooperation should lead to future studies focusing on the use of new raw materials (macroalgae, microalgae, biofloc, insect meal, duckweed meal) in feed for different fish species.
