The European sturgeon Acipenser sturio is the largest migratory fish in French and western European waters. Once present on most major European rivers and along the coasts of the western Atlantic, this species is now seriously threatened with extinction and breeds only in France, in the Garonne and Dordogne rivers, the last known natural reproduction dating back to 1994. The main objective is the restoration of a species, Acipenser sturio, almost extinct from the Garonne Dordogne basin. This restoration can be done from restockings resulting from assisted reproductions carried out on site. The animation of the National Plan is also a key factor in the restoration program. Horizontal principles are respected with gender equality, equality in hiring and non-discrimination, and actions for sustainable development.
