to review existing information on the biology and distribution of sturgeon species in the Danube, Black Sea, Caspian Sea and Adriatic Sea regions;
to determine long-term trends in the dynamics of the stocks and their exploitation patterns;
to determine the current status of the stocks and exploitation based on catch composition (size, species and weight caught), effort, export licences and controls;
establish a comprehensive regional catch assessment programme to support rational management of the stocks. Review existing conservation and management measures and advise on appropriate interventions for the sustainable exploitation of the stocks, including enhancement through aquaculture production and stocking.
