Introduction SEDAR 1 Southpark Circle # 306 Charleston, SC 29414 SEDAR 12 Gulf of Mexico Red Grouper 1. SEDAR Overview SEDAR (Southeast Data, Assessment and Review) was initially developed by the Southeast Fisheries Science Center and the South Atlantic Fishery Management Council to improve the quality and reliability of stock assessments and to ensure a robust and independent peer review of stock assessment products. SEDAR was expanded in 2003 to address the assessment needs of all three Fishery Management Council in the Southeast Region (South Atlantic, Gulf of Mexico, and Caribbean) and to provide a platform for reviewing assessments developed through the Atlantic and Gulf States Marine Fisheries Commissions and state agencies within the southeast. SEDAR strives to improve the quality of assessment advice provided for managing fisheries resources in the Southeast US by increasing and expanding participation in the assessment process, ensuring the assessment process is transparent and open, and providing a robust and independent review of assessment products. SEDAR is overseen by a Steering Committee composed of NOAA Fisheries representatives: Southeast Fisheries Science Center Director and the Southeast Regional Administrator; Regional Council representatives: the Executive Directors and Chairs of the South Atlantic, Gulf of Mexico, and Caribbean Fishery Management Councils; and Interstate Commissions: the Executive Directors of the Atlantic States and Gulf States Marine Fisheries Commissions. SEDAR is organized around three workshops. First is the Data Workshop, during which fisheries, monitoring, and life history data are reviewed and compiled. Second is the Assessment workshop, during which assessment models are developed and population parameters are estimated using the information provided from the Data Workshop. Third and final is the Review Workshop, during which independent experts review the input data, assessment methods, and assessment products. SEDAR workshops are organized by SEDAR staff and the lead Council. Data and Assessment Workshops are chaired by the SEDAR coordinator. Participants are drawn from state and federal agencies, non-government organizations, Council members, Council advisors, and the fishing industry with a goal of including a broad range of disciplines and perspectives. All participants are expected to contribute to the process by preparing working papers, contributing, providing assessment analyses, and completing the workshop report. SEDAR Review Workshop Panels consist of a chair and 3 reviewers appointed by the Center for Independent Experts (CIE), an independent organization that provides independent, expert reviews of stock assessments and related work. The Review Workshop Chair is appointed by the SEFSC director and is usually selected from a NOAA Fisheries regional science center. Participating councils may appoint representatives of their SSC, Advisory, and other panels as observers to the review workshop. SEDAR 12 was charged with assessing red grouper (Epinephelus morio) in the U.S. waters of the Gulf of Mexico. This task was accomplished through workshops held between July 2006 and February 2007. SEDAR12-SAR1-SECTION I. 1 SEDAR 12 Gulf of Mexico Red Grouper 2. Red Grouper Management Overview 2.1. Fishery Management Plan and Amendments The following summary describes only those management actions that likely affect grouper fisheries and harvest. For a complete history of management of the entire reef fish fishery, please contact the Gulf of Mexico Fishery Management Council. Original GMFMC FMP The Reef Fish FMP, including an EIS, was implemented in November 1984. Regulations were designed to rebuild declining reef fish stocks and included prohibitions on the use of fish traps, roller trawls, and powerhead-equipped spear guns within an inshore stressed area and direction to NMFS to develop data reporting requirements in the reef fish fishery. GMFMC Amendments affecting red grouper Amendment 1 (EA/RIR/IRFA), to the Reef Fish FMP, implemented in 1990, set objectives to stabilize long-term population levels of all reef fish species by establishing a survival rate of biomass into the stock of spawning age fish to achieve at least 20 percent spawning stock biomass-per-recruit (SSBR) by January 1, 2000. Among the grouper management measures implemented were: Set a 20-inch total length minimum size limit on red, Nassau, yellowfin, black, and gag grouper; Set a 50-inch total length minimum size limit on jewfish (goliath grouper); Set a five-grouper recreational daily bag limit; Set an 11.0 MP commercial quota for grouper, with the commercial quota divided into a 9.2 MP shallow-water grouper (SWG) quota and a 1.8 MP deep-water grouper (DWG) quota. Shallow-water grouper were defined as black grouper, gag, red grouper, Nassau grouper, yellowfin grouper, yellowmouth grouper, rock hind, red hind, speckled hind, and scamp (until the SWG quota was filled). Deep-water grouper were defined as misty grouper, snowy grouper, yellowedge grouper, warsaw grouper, and scamp once the SWG quota was filled. Jewfish (goliath grouper) was not included in the quotas; Allowed a two-day possession limit for charter vessels and headboats on trips that extend beyond 24 hours, provided the vessel has two licensed operators aboard as required by the U.S. Coast Guard, and each passenger can provide a receipt to verify the length of the trip. All other fishermen fishing under a bag limit were limited to a single day possession limit; Established a framework procedure for specification of TAC to allow for annual management changes; Established a longline and buoy gear boundary at approximately the 50-fathom depth contour west of Cape San Blas, Florida, and the 20-fathom depth contour east of Cape San Blas, inshore of which the directed harvest of reef fish with longlines and buoy gear was prohibited, and the retention of reef fish captured incidentally in other longline operations (e.g., sharks) was limited to the recreational daily bag limit. Subsequent SEDAR12-SAR1-SECTION I. 2 SEDAR 12 Gulf of Mexico Red Grouper changes to the longline/buoy boundary could be made through the framework procedure for specification of TAC; Limited trawl vessels (other than vessels operating in the unsorted groundfish fishery) to the recreational size and daily bag limits of reef fish; Established fish trap permits, allowing up to a maximum of 100 fish traps per permit holder; Prohibited the use of entangling nets for directed harvest of reef fish. Retention of reef fish caught in entangling nets for other fisheries was limited to the recreational daily bag limit; Established the fishing year to be January 1 through December 31; Extended the stressed area to the entire Gulf coast; and Established a commercial reef fish vessel permit. Amendment 3 (EA/RIR/IRFA), implemented in July 1991, provided additional flexibility in the annual framework procedure for specifying TAC by allowing the target date for rebuilding an overfished stock to be changed. It revised the FMP's primary objective from a 20 percent SSBR target to a 20 percent spawning potential ratio (SPR). The amendment also transferred speckled hind from the SWG quota category to the DWG quota category. Amendment 4 (EA/RIR/IRFA), implemented in May 1992, established a moratorium on the issuance of new commercial reef fish permits for a maximum period of three years. Amendment 4 also changed the time of year TAC is specified from April to August and included additional species in the reef fish management unit. Amendment 5 (SEIS/RIR/IEFA), implemented in February 1994, established restrictions on the use of fish traps, created a special management zone (SMZ) with gear restrictions off the Alabama coast, created a framework procedure for establishing future SMZs, required that all finfish except for oceanic migratory species be landed with head and fins attached, and closed the region of Riley's Hump (near Dry Tortugas, Florida) to all fishing during May and June to protect mutton snapper spawning aggregations. Amendment 9 (EA/RIR/IRFA), implemented in July 1994, provided for collection of red snapper landings and eligibility data from commercial fishermen for the years 1990 through 1992. This amendment also extended the reef fish permit moratorium and red snapper endorsement system through December 31, 1995, in order to continue the existing interim management regime until longer-term measures could be implemented. Amendment 16B (EA/RIR/IRFA), implemented by NMFS in November 1999 set a recreational daily bag limit of one speckled hind and one warsaw grouper per vessel, with the prohibition on the sale of these species when caught under the bag limit. Amendment 18A (SEIS/RIR/IRFA) was approved by the Council at the October 2005 Council meeting for submission to the Secretary. This amendment addresses: 1) maximum crew size on charter vessels while commercially fishing, 2) use of reef fish for bait, 3) vessel monitoring systems for commercial reef

This unpublished report forms part of a series compiled by the Capture Section of the South Pacific Commission’s Coastal Fisheries Programme. These reports have been produced as a record of individual project activities and country assignments, from materials held within the Section, with the aim of making this valuable information readily accessible. Each report in this series has been compiled within the Capture Section to a technical standard acceptable for release into the public arena. However, they have not been through the full South Pacific Commission editorial process. On 6 February 1998 the South Pacific Commission (SPC) became the Pacific Community. The Secretariat of the Pacific Community (retaining the acronym SPC) is now the name for the body which administers the work program of the Pacific Community. The names have changed, the organisation and the functions continue. This report was prepared when the organisation was called the South Pacific Commission, and that is the name used in it.

We are calling on you to exercise Canadian leadership in the negotiation of a moratorium on deep-sea bottom trawl fishing on the high seas at the United Nations General Assembly this year. Supporting a moratorium would address the effects of foreign overfishing of straddling stocks that cross Canada’s EEZ on the Grand Banks of Newfoundland. In addition, such an action would be in keeping with Canada’s national and international commitments to biodiversity protection. We further urge you to take action in Canadian waters, by recognizing the effects of trawling and implementing habitat protection measures, gear restrictions and supporting the use of alternative and less destructive gear types. Both actions would be strongly supported by the Canadian public and Canada would truly be seen as a leader in the global movement to restore, conserve and protect the marine environment.
