Particularly in France, aquariologists are very fond of this species: they propose exchanges, sell and buy through internet. They even gave to the species the (obviously erroneous) Latin name of “Procambarus marmor” with the “Procambarus marmor blue” and “Procambarus marmor cherry” as options (P. Nöel, pers. comm., 2009).
I was unaware that Marmorkrebs had a French following. Google Analytics says that French readership of this blog is behind four other European countries.
