Following completion of an Endangered Species Act (ESA) status review for black abalone (Haliotis cracherodii), we, NOAA's National Marine Fisheries Service (NMFS), published a proposed rule to list black abalone as endangered on January 11, 2008. After considering public comments on the proposed rule, we issue this final rule to list black abalone as endangered under the ESA. We also solicit information relevant to the designation of critical habitat for black abalone.
