We, the U.S. Fish and Wildlife Service (Service), announce a 90-day finding on a petition to list 10 sturgeon species as endangered or threatened under the Endangered Species Act of 1973, as amended (Act). Based on our review, we find that the petition presents substantial scientific and commercial information indicating that the petitioned action may be warranted. Therefore, with the publication of this notice, we are initiating a review of the status of these species to determine if listing these 10 species is warranted. To ensure that this status review is comprehensive, we request scientific and commercial data and other information regarding these species. At the conclusion of this review, we will issue a 12-month finding on the petition, as provided in section 4(b)(3)(B) of the Act.
