The last big release of this year‘s fish took place on the Morava in Czech together with Povodi Moravy. In total we could release around 72.000 juveniles this year, together with the last years this adds up to 145.000 released sterlets so far – yay!
Our latest monitoring catch, a nice sterlet lady we caught three times in different seasons over the last year in the very same spot. It is nice to see that she recovered well from when we spawned her artificially this April. Also she did not grow a bit over one year, underlining our assumption that she ist an older gal. We also got our first 0+ recapture..exciting times for sure...and field season only just started!

Visiting the German broodstock facilities and rearing systems for reintroduction of the European sturgeon (A. sturio) and Baltic sturgeon (A. oxyrinchus) in Berlin, Born and the riverbanks of the Odra.
Today we visited the aquatic conservation center for marbled trout (Salmo marmoratus) and white clawed crayfish (Austropotamobius pallipes). The center focuses on cocooning (incubating eggs in the river) and nature like rearing with structures in the tanks, natural food and low densities, following a strict genetic protocol. We were absolutely impressed what was done in the last two years and got many ideas we will include in our concept for a large streamside rearing and holding facility for the Danube Sturgeons.
Film teams from Viennese and German TV stations portrayed our project and its progress.
Successful Summer Sampling. 3 nice sterlets caught, tagged, released. Hope to see you again for spawning season!
