Sturgeon have been swimming through our rivers for millions of years, but in the Danube, these majestic prehistoric fish are on the brink of extinction. That is exactly what this project aims to change. A spectacular EU project is bringing salvation for these endangered giants right to Austria—or, more precisely, to Vienna.
A specially converted ship is mooredon Vienna’s Danube Island, serving as a floating breeding station. The goal of the ambitious LIFE-Boat 4 Sturgeon project is to breed rare species such as the sterlet sturgeon and the imposing beluga sturgeon and to save them from extinction through targeted releases into the wild. What makes this project unique is that the young fish are raised directly in filtered Danube water. This allows them to becomeaccustomed to their natural habitat from an early age, which drastically increases their chances of survival in the wild.
Up-close insights into a floating high-tech laboratory for sturgeon
Visitors to the ship are immersed in the world of modern species conservation. On site, they gain an exclusive insight into how scientists preserve the genetic diversity of sturgeons and raise the fish from tiny eggs to robust juveniles.
At the same time, ecological knowledgeis brought to life. You’ll learn why sturgeons are indispensable as a keystone species for a healthy Danube and what extreme dangers— from river dams to habitat loss—the animals face. Researchers also demonstrate fascinating methods for examining and caring for the fish without causing them stress, as well as marking them for later identification.
An unforgettable experience for young and old alike
The project offers far more than just theory. A real highlight is the regular educational programs and hands-on activities right on the water. At special events, interested visitors can even witness firsthand the ceremonialrelease of the newly reared sturgeons into the wild. And anyone who wants to support this ambitious project can even adopt a sturgeon and give it a name!
LIFE-Boat 4 Sturgeon turns nature conservation into a tangible adventure right in the heart of Vienna. It impressively demonstrates how research, species conservation, and experiential education work together to guide these prehistoric giants toward a secure future right on our doorstep.
