Congratulations to Moritz Benz 🥳.
He successfully defended his MSc thesis in which he examined the important role of connected tributaries for cyprinid fish species.

Our sledding happens on the Danube, not the slopes! 🚤🛷 With lights and a camera on board, our custom sled explores the riverbed—where winter vibes meet underwater research. 🌊📽️

Our 2024 sampling campaign wraps up this week! Despite chilly nights, we tagged 2,000 more fish. Excited to see how many show up on our antennas next spring as they head to spawn—some already showing staring spawning rash!

Thanks to the well thought-out installation, our antennas survived the September floods and delivered data.
Only the antenna in the Schwechat had to be reinstalled, as parts of it were twisted by the sediment movement.

Successful installation of another PIT tag antenna in the Schwechat, a tributary of the Austrian Danube.
This will provide us with further data on the migration of tagged fish in the Danube.

Our team defies the sommer heat and is out in the field day and night. Just like the algae and macroinvertebrates, we defy the ship waves and explore the gravel banks with the fish at night.
