AB  - The presence of Atlantic sturgeon (Acipenser sturio) and ship sturgeon (Acipenser nudiventris) in the Danube has been known through only occasional, chance sightings; significant uncertainty remains as to whether these species are already extinct or still present in the Danube River basin. In this study, five different statistical methods were applied for assessment of their extinction probability. All methods provided a significant probability that the Atlantic sturgeon is extinct, with extinction having occurred somewhere between 1966 and 1970. Although the applied methods provided different results, all indicated that the ship sturgeon is probably still present, but that extinction may occur within a few decades. Sensitivity analyses of these statistical methods projected that new sightings of ship sturgeon in the coming years would not extend the length of extinction by more than a few years. The best management approach for these two species, given the lack of knowledge on their presence in the Danube River basin, could be to apply all feasible protection measures for the other four Danube sturgeon species. These measures could at the same time provide protection for these two species, presuming they are not already extinct or beyond recovery.

AB  - Sturgeon species in the Danube River basin have experienced severe decline. Besides overexploitation, habitat loss, and pollution, they are further endangered by lack of efficient policy and management, as well as by serious lack of knowledge about their life history. Although population viability analysis (PVA) could represent an extremely valuable tool to cope with these problems, it has not so far been applied to Danube populations. This paper represents an assessment of different PVA methods and models developed for sturgeon species. It analyzes their results, main advantages, drawbacks, and problems, and discusses the possibility of applying PVA to sturgeon populations in the Danube River basin.
