That is definitely and Acipenser species or Hybrid of such. I'm not seeing anything in it that would relate to Scaphirhynchus.
Scaphirhynchus Have very broad and flattened heads and are very narrow and elongated post Dorsal fin. While coloration is not diagnostic, Juveniles of the size depicted in Scaphirhynchus are also usually a light tan to buff coloration. Barbel count for Acipenser ruthenus, gueldenstaedtii, sturio, Huso species and the Scaphirhynchus species is the same being typically at four.
Snout in Acipenser ruthenus of this age class are also not typically as distinctly pointed as in older age class fish. I personally highly suspect given the traits figured that this fish is a Hybrid type between two of the European species A good guess would be A.ruthenus x sturio or A. ruthenus x Huso Sp. ( Huso or Dauricus).. These are common in the pet hobby and often available. A. ruthenus x A. gueldenstaedtii is a possibility also but the one pictured does not seen to have some particular traits of that hybrid.

There was an auction on e-bay from someone in Oswego, Illinois, he told me the fish were shovelnose and that he got them from someone in California. They were said to have originated from a tropical fish supplier in Asia but were supposed to have come from the USA originally. I was told at one time by a breeder that most of his shovelnose sturgeons were going to Asia. The guy sent me the pics and i asked him if I could post them to the forum to see if his ID was correct. (he wasn't completely sure) The auction has ended now, his price was far too high for me even though i have long wanted some shovelnose sturgeon.

Sadly you are correct, almost no shovelnose are ever sold in the USA, for some reason it is much cheaper to import a fish bred in Europe than to sell a fish already bred in the USA not to mention already native to the USA.
Sturgeons in captivity seems to be a much more popular idea in Europe with some color varieties and even crosses with odd scale patterns available as well.
Some West coast sturgeon, mostly white sturgeon, do make their way into the pet trade but these are fish that really need cold water and seldom live long in captivity even in ponds.
The idea that is wide spread in the pet trade that fish are disposable and the fact a fish has zero possible survival is ok as long as you can sell them before they die.
Of course from the point of view of the environment all such fish are dead already but it chaps me to see fish sold that are often misrepresented as smaller warm water fish that are actually huge cold water fish doomed to die quickly no matter how hard the person who bought them tries.
Another problem I have with Sterlets being sold as shovelnose is the possibility they might be released by well meaning people and I have heard sterlets called the "carp" of the sturgeon group. Sterlets crowding out native sturgeon is a very scary idea.
