on a trip to cologne, germany last weekend i learnt of this project in cologne aquarium. I managed to get a 20 page leaflet (in german) from the very useful staff (who didnt speak english) which i am currently translating, it contains useful info on: astacus astacus, austropotamobius torrentium, astacus leptodactylus, orconectes limosus, pacifastacus leniusculus, procambarus clarkii and a few more as well as a table which could prove very useful for cray ID. I will post up bits here as i translate as well as adding pics and other bits of info.
