The population of the Atlantic Baltic sturgeon, Acipenser oxyrinchus, occurring in the Baltic Sea was recognized as extirpated in the mid twentieth century. Since 2004, work has been underway in Poland to restore the Baltic sturgeon species. The material used in this project comprises fertilized eggs and hatch obtained from Atlantic sturgeon spawners from the St. John River and imported from Canada. The aim of the ichthyological work being done as part of this project is to rear stocking material and create a broodstock under aquaculture conditions. In the 2006-2013 period, approximately 766,300 fry individuals with mean weights ranging from of 5-9 to 1500 -2500 g were released into Polish rivers. The goal of these pilot stocking programs was to study migration routes and the behavior of the fry in the rivers. The oldest individuals in select stocks are beginning to mature. Stocking has been expanded in recent years to include Neman and Pregola river tributaries. A further consequence of stocking and expanding areas that are stocked to include all of the historic sturgeon rivers in the Baltic Sea basin, in the opinion of the authors, should lead to the restoration of the Baltic sturgeon population.
