Sturgeons are among the most endangered species of fish worldwide. The project “Sustainable protection of lower Danube sturgeons by preventing and counteracting poaching and illegal wildlife trade” is coordinated by WWF Austria and implemented by WWF in Austria, Bulgaria, Romania, Serbia and Ukraine, together with Danube Delta Biosphere Reserve Authority in Romania and IZW Leibniz Institute for Zoo and Wildlife Research in Germany. ��������IP���lw0�4�;p0�;��`�ghX�����Aw����@�*$A�60F0�LO`���� �`��#��G8;��0,�1�`e�-u@�P*��ό�K��32pU��Lsࢬ\=���� ��$|

In collaboration, they work on the foundations for developing and conserving stable sturgeon stocks. Under the Endangered Species Act, NOAA Fisheries must list threatened and endangered marine species regardless of where they are found. Both North Sea tributaries were once dominated by the European variety of sturgeon (Acipenser sturio). h�b``�f``�```�*��� The European sturgeon is found in southwestern France and western Georgia. %PDF-1.4
