The project LIFE-Boat 4 Sturgeon builds upon the methods and results of the LIFE-Sterlet project. It has the aim to establish a genetically diverse captive broodstock of mature animals for all four remaining Danube sturgeon species in at least two locations (AT and HU). Those stocks will be maintained over the long-term to preserve the gene pool and to support  all four species with genetically diverse, autochthonous and fit juveniles. In Austria, a floating rearing station in the Danube in the centre of Vienna will be built in addition to the existing LIFE-Sterlet hatchery container. The mother fish stock of all species will be constantly expanded through different genotypes and the reproduction through a studbook enables the greatest possible genetic diversity of the offspring. Existing monitoring efforts are to be continued and intensified to document the development of the populations. Furthermore, an investigation along the whole Danube for possible residual populations, will be carried out. F or the whole Danube Region and other European catchments a long-term database and manual for ex situ actions and monitoring in sturgeon conservation will be provided. Further objectives are the coordination with fishing authorities and communities along the Lower Danube and Black Sea to reduce IUU fishing and to raise general public awareness.
