Baikal sturgeon (Acipenser baerii 'baicalensis')

Have you seen any Siberian taimen here?

@Veno Yes, one animal. I uploaded my picture to the Czech wildlife database Biolib.

@Sicarius
I was beginning to doubt whether this species still existed in the place because no photos were circulating, as if Japanese aquarium enthusiasts were unaware of its value. But it's good to know that it still exists. Does this species exist in captivity anywhere else? By the way, it's an excellent photo!

@Veno I am not aware of any other holders worldwide. Thank you
