Endangered and Threatened Wildlife and Plants; Proposed Rule To List the Shovelnose Sturgeon as Threatened Due to Similarity of Appearance

摘要

We, the U.S. Fish and Wildlife Service (Service or USFWS), propose to treat the shovelnose sturgeon (Scaphirhynchus platorynchus) as threatened under the "Similarity of Appearance" provisions of the Endangered Species Act of 1973, as amended (Act). The shovelnose sturgeon (Scaphirhynchus platorynchus) and the endangered pallid sturgeon (Scaphirhynchus albus) are difficult to differentiate in the wild and inhabit overlapping portions of the Missouri and Mississippi River basins. Four States where the two species commonly coexist allow for commercial fishing of shovelnose sturgeon which is in demand for its roe (eggs sold as caviar). The close resemblance in appearance between the two species creates substantial difficulty for fishermen, State regulators, and law enforcement personnel in differentiating between shovelnose and pallid sturgeon, both whole specimens and parts (including flesh and roe). This similarity of appearance has resulted in the documented take of pallid sturgeon and is a threat to the species. The determination that the shovelnose sturgeon should be treated as threatened due to similarity of appearance will substantially facilitate law enforcement actions to prot
