Source of Base Data Creating these Units:

The shoreline was created using Acropora critical habitat data (from NOAA NCCOS Benthic Habitat Mapping 2000-2002 - land and mangrove attribute combined for shoreline) https://coastalscience.noaa.gov/project/benthic-habitat-mapping-puerto-rico-virgin-islands/. Contours were derived from the National Geophysical Data Center’s 2004 U.S. Coastal Relief Model https://www.ngdc.noaa.gov/mgg/coastal/crm.html. The NCCOS Benthic Habitat Mapping program provides data and maps at http://products.coastalscience.noaa.gov/collections/benthic/default.aspx, which was used to pull in substrate data. Benthic data was also used from The Nature Conservancy and can be found and downloaded here: https://sites.google.com/view/caribbean-marine-maps

Standardized metadata has been prepopulated for the Fields and Values and the standard spatial reference is the World Geodetic System 1984 geographic coordinate system (GCS_WGS_1984, EPSG well-known identifier 4326).

Listing Status = Federal status of a taxon under the federal Endangered Species Act.

Critical Habitat Status = Status of Critical Habitat Designation (i.e. Proposed or Designated)

Unit = Location of Identified Critical Habitat

Taxon = Taxon

Lead Office = NMFS Regional Office

Federal Register Rule = Public official notice of Rule

Publication Date = Publication Date of Federal Register Notice

Effective Date = Effective Date of Rule

Area SqKm = Area of Unit in Square Kilometers

eCFR = Link to designated critical habitat regulatory text and maps published in the eCFR.

Shape_Length = dynamic geodatabase field. Automatically calculated in the units of the output coordinate system specified by the Spatial Reference parameter by ESRI.

Shape_Area = dynamic geodatabase field. Automatically calculated in the units of the output coordinate system specified by the Spatial Reference parameter by ESRI.

Purpose:

This layer displays the Proposed Critical Habitat designations for Nassau grouper, Epinephelus striatus. NMFS proposes to designate critical habitat for the threatened Nassau grouper pursuant to section 4 of the Endangered Species Act (ESA). Specific occupied areas proposed for designation as critical habitat contain approximately 2,353.19 sq. kilometers (908.57 sq. miles) of aquatic habitat located in waters off the coasts of southeastern Florida, Puerto Rico, Navassa, and the United States Virgin Islands (USVI).

The Nassau grouper is a reef fish. It is a member of the family Serranidae, which includes groupers valued as a major fishery resource such as the gag grouper and the red grouper. These large fish are associated with hard structures like reefs (both natural and artificial), rocks, and ledges. They are late-maturing, long-lived, top-level predators found in tropical and subtropical waters of the western North Atlantic. This includes Bermuda, Florida, Bahamas, the Yucatan Peninsula, and throughout the Caribbean to southern Brazil.

The Nassau grouper is considered a reef fish, but undergo ontogenetic shifts in habitat utilization: larvae settle in nearshore habitats and then as juveniles move to nearshore patch reefs (Eggleston, 1995), and eventually recruit to deeper waters and reef habitats (Sadovy and Eklund, 1999). As adults, individuals are sedentary except for when they aggregate to spawn - the timing of which appears to be linked to both lunar cycles and water temperature (Kobara et al., 2013). Maximum age has been estimated as 29 years, based on an ageing study using sagittal otoliths (Bush et al., 2006). Maximum size is about 122 cm total length (TL) and maximum weight is about 25 kg (Heemstra and Randall, 1993).

Nassau grouper used to be one of the most common species of grouper in the United States. It was easy for commercial and recreational fisherman to catch Nassau grouper and it soon became scarce. The remaining stocks are overexploited. In some cases, Nassau grouper is commercially extinct through much of its geographical range.

Currently, all harvest of Nassau grouper is prohibited in the United States. Nassau grouper is listed as threatened under the Endangered Species Act. NOAA Fisheries is dedicated to the conservation of Nassau grouper.
