At the Aquaworld exhibition of the VÖAFV – Verband der Österreichischen-Arbeiter-Fischerei-Vereine, our project was allowed to be part of the tour stop in Vienna. In the 60 000 liter tank outside you could find the large sturgeon species such as Beluga sturgeon and Russian sturgeon, whilst 5 of our sterlets from this year’s rearing could be viewed in a small aquarium in the exhibition tent.
