SUBJECT CATEGORY: Fisheries of the Caribbean, Gulf of Mexico, and South Atlantic; Reef Fish Fishery of the Gulf of Mexico; Vermilion Snapper; Notification of an Overfished Fishery
DOCUMENT SUMMARY: NMFS has determined that the Gulf of Mexico vermilion snapper fishery is overfished and has notified the Gulf of Mexico Fishery Management Council (Council) of related responsibilities under the MagnusonStevens Fishery Conservation and Management Act (Magnuson Stevens Act).
SUMMARY: Caribbean, Gulf, and South Atlantic fisheries—; Gulf of Mexico reef fish; vermilion snapper,
NMFS' determination of the status of a stock relative to overfishing and an overfished condition is based on both the rate of removal of fish from the stock through fishing (the exploitation rate) and the current stock size. When the exploitation rate jeopardizes the capacity of a stock to produce its maximum sustainable yield (MSY) on a continuing basis, overfishing is occurring. The exploitation rate is usually expressed in terms of an instantaneous fishing mortality rate (F).
Another important factor for classifying the status of a resource is the current stock level. If a stock's biomass falls below its minimum stock size threshold, the capacity of the stock to produce MSY on a continuing basis is jeopardized, and the stock is considered to be in an overfished condition.
Estimated total landings of Gulf vermilion snapper peaked in the early 1990s and have declined through the late 1990s for both the commercial and recreational sector. Commercial catches dropped 20 percent over this time period while recreational catches declined over 30 percent. Catch per unit effort, an indication of abundance, declined in three different fishing sectors, including the commercial handline fishery, and the western and eastern Gulf paid passenger recreational fishery (headboats). The decline in catch per unit effort was most extreme in the eastern Gulf headboat fishery, with this index dropping over 75 percent in value. Reductions were also seen from 1993 to 1999 in two fisheryindependent surveys.
The 2001 vermilion snapper stock assessment evaluated the current condition of the Gulf vermilion snapper stock using two different scientific models: a surplusproduction model and a virtual population analysis (VPA). The VPA results varied greatly depending on the inputs to the model. Moreover, vermilion snapper are known to vary widely in their size at age. As a result, the Reef Fish Stock Assessment Panel (RFSAP) concluded that these analyses were highly uncertain and excluded them from consideration of stock status.
The surplusproduction models gave consistent results across a wide
range of model inputs, with only one scenario (eliminating data from
the most recent 3 years) showing significant differences. All other
model formulations indicated that vermilion snapper was overfished and
experiencing overfishing. The preferred model formulation indicated
that this stock experienced a fishing mortality rate in 1999 nearly
twice the rate associated with MSY (i.e., F
The RFSAP supported the assessment's results indicating that Gulf vermilion snapper are overfished and experiencing overfishing. The Gulf of Mexico's Scientific and Statistical Committee concluded that the RFSAP report represented the best available scientific advice to the Council for establishing catch limits for vermilion snapper.
Section 304(e) of the MagnusonStevens Act requires that within 1
year of being notified of the identification of a stock as being
overfished, the affected Regional Fishery Management Council must
develop measures to end overfishing and rebuild the stock. On October
31, 2003, the Administrator, Southeast Region, NMFS, notified the
Council of the overfished status of the Gulf of Mexico vermilion
snapper and requested that the Council take appropriate action. The letter to the Council reads as follows:

Ms. Bobbi Walker, Chairperson
Gulf of Mexico Fishery
Management Council

Tampa, Florida 33619
Dear Ms. Walker:
This is to inform the Gulf of Mexico Fishery Management Council (Council) that, based upon the best available scientific
information, the National Marine Fisheries Service (NOAA Fisheries)
has determined that the Gulf of Mexico vermilion snapper stock is
overfished and undergoing overfishing. This determination is based
on the July 2001 Status of the Vermilion Snapper Fishery in the Gulf
of Mexico Report (Assessment 5.0), the October 2001 Report of the
Reef Fish Stock Assessment Panel, and the Summary of the Standing
and Special Reef Fish SSC Meeting from the January 2002 Council
meeting. The analyses concluded that vermilion snapper biomass was
32% of the biomass associated with maximum sustainable yields (BMSY)
in 2000. This estimate fell well below the minimum stock size
threshold of 75% of BMSY. The analyses also concluded that the stock
experienced a fishing mortality rate in 1999 of nearly twice the
rate associated with MSY (FMSY). Several assessment scenarios were
examined, all but one of which gave similar results. These analyses
indicate that the vermilion snapper stock is overfished and
undergoing overfishing. Dr. Nancy Thompson, Director of the
Southeast Fisheries Science Center, will attend the November Council
meeting to respond to questions the Council may have regarding the assessment.
The MagnusonStevens Fishery Conservation and Management Act
requires that within one year of the determination that the stock is
overfished the Council must propose a rebuilding plan; however, as
pointed out in an April 12, 2002, letter from Dr. Joseph Powers, the
Council must take action as soon as possible to end overfishing. The
2001 stock assessment provided guidance on measures necessary to end [[Page 62543]]
overfishing and rebuild the stock within 10 years. It estimates that
40 to 50 percent catch reductions are necessary to end overfishing
and to rebuild vermilion snapper. Ongoing efforts have already identified options to achieve these reductions.
We are now required to develop a formal rebuilding plan. I anticipate that a single amendment to the Reef Fish Fishery Management Plan can serve as a rebuilding plan and also enact measures to end overfishing. This administrative strategy could potentially delay efforts to end overfishing of vermilion snapper. Consequently, I am willing to issue an interim rule sooner, if necessary, to end overfishing once suitable regulations have been identified.
I look forward to working with the Council in developing a plan for rebuilding the vermilion snapper stock.
Sincerely yours,
Roy E. Crabtree, Ph.D.
Regional Administrator
