The good: -In the last days we obtained roughly 90.000 sterlet eggs from two wild females, fertilized by two wild males.
On Easter Sunday, the documentary "Vienna, a Water City in Climate Change" was broadcast on ORF. In this very informative contribution about the past and future of Vienna's waters we are also represented with our project. For the documentary by Susanne Riegler, a film team visited us in the breeding station in mid-March.
Thanks to our Hungarian colleagues from Naik Haki the first batch of eggs is incubated.
Our own wild spawners look nice as well and with the steady rise of water temperature we will start artificial propagation by the end of next week.
It's that time of the year again. Operating with a skeleton crew and working from home as much as possible we still need to collect our broodstock for reproduction in April.
New LIFE-sterlet team member! Oihane from Bilbao, Spain is doing a three-month internship in our project, supporting us in the catch of broodstock, reproduction, rearing and telemetry tracking. Welcome!
Yesterday we chose 29 fish that had the right size and today they went into surgery. They were anesthetized and then we implanted the hydroacoustic tag and stitched the small cut. Afterwards we observed them for several hours before they were released into the Danube. Together with Viadonau we already set up the receiver stations at the Nationalpark Donauauen last week and starting today we will learn more about their habitat use and movements. This will be supplemented via active tracking by boat.
The LIFE team and the sterlets wish you happy holidays and a good start to 2020. IA
The ICPDR meets annually to review recent activities and plans for the upcoming year. On the second day the first We Pass Stakeholder Workshop took place. We Pass is an initiative aiming to facilitate fish migration in the Danube River Basin. Their focus is on the preservation and reestablishment of endangered fish species migration routes in the Danube River, its tributaries, and specifically at the Iron Gates.
Talks by experts from the field were held, including two lectures by Thomas Friedrich on our activities to protect the sturgeon. Experts from the Danube Sturgeon Task Force discussed in working groups the key question of the project: How do we get the public to engage with the issues of disruption to fish migration in the Danube River Basin?
Another season has ended well, and we are happy about the continuing attention at our sterlets. In November the Augustin interviewed us for their kids page and the Wiener Bezirksblätter visited us and published an article.nbsp]
A cooperation with the Federal Agency for Water Management in Scharfling enables us to raise potential future mother fish in the fish farm Kreuzstein and to keep them available for future projects. Therefore, we transferred 80 sterlets to Scharfling.
