Chef Hayes, The two grouper species I am familar with are Black (very rare) and red. They each have sub Species Jewfish, Nassau,red,red hind, warsaw and yellow edge. A grouper in fact is one of over 400 kinds of sea bass (Serraind). The only other one I know is GAG or grey grouper,but it is not a true grouper. I am not familar with the blue grouper, so I can not answer for sure.
I hope this helps alittle
