From October 3 to 7, Vojtěch Kašpar, Roman Franěk, Tomáš Tichopád and Martin Hubálek actively participated at the annual Aquaculture Europe 2021 conference, which took place in Funchal, Portugal. We presented our most recent results in form of posters focused on reproduction technologies for cyprinid and sturgeon fishes. At the same time, we had the opportunity to meet our foreign colleagues in person after a long time and discuss current results and opportunities for further collaboration. The business trip was supported by projects NAZV QK1910428, Biodiversity CZ.02.1.01 / 0.0 / 0.0 / 16_025 / 0007370 and LAB RVO.
