NOAA Fisheries announces its intent to conduct 5-year reviews for the black abalone (Haliotis cracherodii) and the white abalone (Haliotis sorenseni) under the Endangered Species Act of 1973, as amended (ESA). Both the black abalone and white abalone are listed as endangered under the ESA. NOAA Fisheries is required by the ESA to conduct 5-year reviews to ensure that the listing classifications of the species are accurate. The 5-year reviews must be based on the best scientific and commercial data available at the time. We request submission of any such information on black abalone and white abalone, particularly information on the status, threats, and recovery of the species that has become available since the final listing decision for white abalone in May 2001 and black abalone in January 2009.
