Norway ate the poor thing so no evidence.
Well, Beluga caviar is tasty...so the whole Beluga has to be nummy too, eh?
Well, considering that Beluga Whales are mammals and therefore deliver live births as opposed to roe (fish eggs), I'm not too sure. But even Beluga Sturgeons (which produce Beluga caviar) are a member of the Sturgeon family and I have heard those fish do not taste very good. Just saying.
