According to Liu Jian, the Chinese sturgeon is a national first-class protected animal, and it cannot be produced or operated, let alone eaten. He said that the "Chinese sturgeon" mentioned by many merchants is actually a hybrid sturgeon. "There are 27 species of sturgeon in the world, most of which are first-class and second-class protected animals. Only one species of sturgeon can be used for food when it has legal documents." According to Liu Jian, the most direct way to distinguish between Chinese sturgeon and hybrid sturgeon is to judge from the snout of the sturgeon. The snout of the real Chinese sturgeon is round, while that of the hybrid sturgeon is slightly pointed and slightly upturned. He called on everyone to abide by national laws and establish a sense of protection for precious animals such as Chinese sturgeon.
