The reproduction was very successful again this year and our fry are eating diligently. Bred brine shrimp (Artemia), also known as primeval shrimp, serve as their first food.
We can report a huge success of our project! We recaptured the first mature fish stemming from our facility. This male was hatched and released in 2017 and now 4 years later we could use it to fertilize eggs of four female wild fish we caught in the last weeks.
The current status of our project is reported in the magazine "Fisch & Wasser“ of the VÖAFV. The result is a review of a "disturbed“ year, successes in reproduction, and outlooks on what is to come.

We started the sampling for broodstock, and out of 8 sterlets we could catch, only one was not a recapture.
The new season is about to start and in the next weeks we will move our workplace more and more to the water. In addition, we are also pleased about the continuing interest in our project. The Kronen Zeitung has published a small article in its issue of February 22.
The radio show „Radiokolleg“ features the topic of drinking water in Austria from Feb 01 - Feb 04 with insights into the topic of water research.
The last fish for this year are being released and we also have a small reason to celebrate: 202.000 released sterlets. In the next few weeks the hatchery container will be be prepared for winter, and we keep looking for our tagged fish.
We already released 50.000 juveniles in all project areas in 2020. The rest of them is peacefully swimming around, sharing the basins with around 1.000 small Russian sturgeons. A share of the small Russian sturgeons was also transferred to our Hungarian partner to divide the risk and give them space to grow.
The first part of this year’s World Fish Migration Days took place as webinar on the 14th of May. Sturgeons and LIFE Sterlet were featured in a presentation. You can re-watch the whole webinar here: https://www.youtube.com/watch?v=8y9zCMzcOog&t=3392s.
This years`Danube Day took place digitally in form of a riddle-rally for kids. Supported by Robert Steiner in several YouTube Clips, the Danube detectives had to solve and learn many riddles on the Danube and its inhabitants. You can re-watch the clip with our sterlets here: https://www.youtube.com/watch?v=tVDIJdle09U.
Additionally the sterlets have been featured in the Sunday kids section of Austria’s largest newspaper.
