Blue bastard, new fish species

It seems they discovered a new fish species, the name given to it is really funny: Plectorhinchus caeruleonothus, deriving from ‘blue bastard’. Why? It is blue when adult and ‘a bastard to catch’  :).
Here is one of the websites that describe how to deal with it with fly-fishing tackle. Wish there were some in the Stausee…..    😉
