The booklet goals at synthesizing our present wisdom of Acipenser sturio and its administration. This species, some of the most common sturgeon species in every single place Western Europe starting from the Black Sea to the Baltic, is now at the verge of extinction. significant elements of its biology and administration, together with mismanagement, are supplied in a ancient viewpoint. equally, the adjustments within the recovery courses (in situ and ex situ) initiated in France and Germany are provided. because the species happened in sympatry with Acipenser oxyrinchus in Germany and Poland and intensely lately in France besides, a short outlook on restoration-management courses of A. oxyrinchus also are supplied for either North the US and northerly eu international locations, specifically Germany and Poland. As conservation-restoration activities transcend medical matters, non-governmental stakeholders and marine specialist fishermen’s enterprises have additionally been requested to give a contribution, and the major position of a French-German cooperation plan is underlined. part of the publication is dedicated to views. Illustrations of the ecu sturgeon, in general in pictures, but in addition in stamps and work, are presented.

Example text

Sturio and A. oxyrinchus are very similar and represent a sister clade in comparison to all other sturgeon species. Moreover, the molecular data favour the hypothesis that A. sturio and A. oxyrinchus are the oldest clade within the genus Acipenser (Ludwig et al. 2000). It is reasonable to presume that about 90 M years ago there was an ancestral Atlantic Acipenser form (Birstein and Doukakis 2000), which later divided into two forms (presumably A. sturio and A. oxyrinchus), now surviving on the opposite sides of the North Atlantic: therefore, their interbreeding is presently prevented.

Some works deal with other species (Bartosiewicz and Takacs 1997) or address specific aspects (Findeis 1997; Hilton and Bemis 1999). Working on animals listed as threatened with extinction and appearing on the red list of endangered species sets the problem of constituting a reference collection of individual skeletons characterizing size, mass, age and origin.
