The ebook goals at synthesizing our present wisdom of Acipenser sturio and its administration. This species, some of the most common sturgeon species in all places Western Europe starting from the Black Sea to the Baltic, is now at the verge of extinction. significant points of its biology and administration, together with mismanagement, are supplied in a old point of view. equally, the adjustments within the recovery courses (in situ and ex situ) initiated in France and Germany are offered. because the species happened in sympatry with Acipenser oxyrinchus in Germany and Poland and extremely lately in France in addition, a short outlook on restoration-management courses of A. oxyrinchus also are supplied for either North the United States and northern ecu international locations, specifically Germany and Poland. As conservation-restoration activities transcend medical concerns, non-governmental stakeholders and marine specialist fishermen’s firms have additionally been requested to give a contribution, and the foremost function of a French-German cooperation plan is underlined. part of the publication is dedicated to views. Illustrations of the ecu sturgeon, mostly in images, but additionally in stamps and work, are presented.

Example text

When there is only one scute left, it is often impossible to establish if it is the largest one (which gives us information on the maximum size) or one of the smallest ones of a large individual. (ii) Another difficulty, when several scute fragments are present, is that it is hard to say whether they belong to the hundreds of scutes of a same individual or whether, on the contrary, the scutes belong to different individuals. Therefore, we will also integrate the archaeological context data (stratigraphy, spatial distribution) in order to evaluate the minimum number of individuals (Desse-Berset 2009b).

These results are supported by analyses of other sequences of mitochondrial genes in a higher number of species (Birstein et al. 2002). Moreover, molecular phylogeny analyses based on cytochrome b sequences support the separation of these two species from the other 13 species belonging to the subfamily Acipenserinae (Ludwig et al. 2001). Also, recent studies on satellite DNA distribution in the same 15 species of Acipenserinae by Southern blot hybridization show that PstI satellite DNA sequences are present in all species analyzed, while HindIII satellite DNA sequences are present in all species except A.
