On September 3, 2010, we received a petition from the WildEarth Guardians to list speckled hind (Epinephelus drummondhayi), goliath grouper (Epinephelus itajara), and Nassau grouper (Epinephelus striatus) as threatened or endangered under the ESA. Due to the scope of the WildEarth Guardians’ petition, as well as the breadth and extent of the required evaluation and response, we are providing species-specific findings on the petition. This finding addresses WildEarth Guardians’ petition to list Nassau grouper. We have reviewed the petition, the literature cited in the petition, and other literature and information available in our files. We have concluded the petition presents substantial scientific or commercial information indicating that the petitioned action may be warranted for Nassau grouper.
