My comments about a name change has stirred some debate among readers of this blog, my reason for a change is simple it is acceptance, the name black fish is a good description most of the time, it is true when you catch a fish out of a over grown river or stream they are black however in a world where perception is everything cod is a far more appealing sounding name and might engender more good will towards the  fish, southern cod is probably not correct because there range extended far outside the southern reaches of east Aust perhaps eastern cod or as I said in a previous post marbled cod .
