4. 3. Population viability analysis of the Danube sturgeon populations

   University essay from SLU/Swedish Biodiversity Centre

   Author : Ivan Jarić; [2009]
   Keywords : Acipenser; Huso; sturgeon; PVA; extinction risk; life history; modelling; pectoral fin microchemistry; Sr : Ca ratio; sighting records; Danube;

   Abstract : Populations of six sturgeon species in the Danube River (Beluga, Russian sturgeon, Stellate sturgeon, Sterlet, Ship sturgeon and Atlantic sturgeon) have experienced severe decline during the last several decades, mostly due to the unsustainable fishery, river fragmentation and water pollution. In the present study, the question of viability of Danube sturgeon populations and the poor knowledge of their ecology have been addressed through three different research activities: 1) statistical methods that infer extinction based on sighting records have been used to assess probability of extinction of the Ship and Atlantic sturgeon, whose presence n the Danube basin is uncertain; 2) assessment of microelement accumulation in sturgeon pectoral fin rays, especially of strontium and calcium, has been conducted as a method that can reveal migration patterns of anadromous sturgeons; 3) population viability analysis in a Vortex simulation model has been conducted in order to assess the state of the six Danube sturgeon species, their future risk of extinction and to determine the most suitable conservation and management measures.
