Fisheries of the Caribbean, Gulf of Mexico, and South Atlantic;
Reef Fish Fishery of the Gulf of Mexico; Amendment 44
AGENCY: National Marine Fisheries Service (NMFS), National Oceanic and
Atmospheric Administration (NOAA), Commerce.
ACTION: Notification of Agency decision.
-----------------------------------------------------------------------
SUMMARY: NMFS announces the approval of Amendment 44 to the Fishery
Management Plan for the Reef Fish Resources of the Gulf of Mexico (FMP)
as submitted by the Gulf of Mexico (Gulf) Fishery Management Council
(Council). Amendment 44 revises minimum stock size thresholds (MSST)
for seven stocks in the Gulf of Mexico (Gulf) reef fish fishery
[[Page 61488]]
management unit. The MSST is revised for the gag, red grouper, red
snapper, vermilion snapper, gray triggerfish, greater amberjack, and
hogfish stocks. The need for Amendment 44 is to provide a sufficient
buffer between spawning stock biomass at maximum sustainable yield
(BMSY) and MSST to reduce the likelihood that stock status
changes frequently between overfished and not overfished as a result of
scientific uncertainty or natural fluctuations in biomass levels.
DATES: The amendment was approved December 21, 2017.
ADDRESSES: Electronic copies of Amendment 44 may be obtained from
www.regulations.gov or the Southeast Regional Office website at http://sero.nmfs.noaa.gov. Amendment 44 includes an environmental assessment
and a fishery impact statement.

SUPPLEMENTARY INFORMATION: NMFS and the Council manage the Gulf reef
fish fishery, which includes gray triggerfish, under the FMP. The
Council prepared the FMP and NMFS implements the FMP through
regulations at 50 CFR part 622 under the authority of the Magnuson-
Stevens Fishery Conservation and Management Act (Magnuson-Stevens Act)
(16 U.S.C 1801 et seq.). Amendment 44 was prepared by the Council and
will be incorporated into the management of Gulf reef fish through the
FMP.
On September 25, 2017, NMFS published a notice of availability
(NOA) for Amendment 44 and requested public comment (82 FR 44582).
In 1999, the Council submitted the Generic Sustainable Fisheries
Act Amendment to comply with status determination criteria (SDC)
requirements of the Sustainable Fisheries Act of 1996. NMFS approved
most of the fishing mortality threshold (MFMT) criteria, but
disapproved all of the definitions for maximum sustainable yield (MSY),
optimum yield (OY), and MSST. The Council subsequently began
establishing these reference points and SDC on a species-specific basis
as stock assessments were later conducted, and is currently preparing a
plan amendment to address all of the unassessed reef fish stocks.
Amendment 44 focuses on those assessed stocks with MSSTs, which are
gag, red grouper, red snapper, vermilion snapper, gray triggerfish,
greater amberjack, and hogfish. Red snapper, gray triggerfish, and
greater amberjack are currently considered overfished because their
stock size is below MSST and are under rebuilding plans. The other four
stocks are not considered overfished (gag, red grouper, vermilion
snapper, and hogfish) because their stock size is above MSST.
For most of the assessed federally managed reef fish stocks in the
Gulf with defined MSSTs, the overfished status, when applied, has been
evaluated using the formula: (1-M) * BMSY (M is the natural
mortality rate and B is a measure of stock biomass). For some stocks
that have a very low natural mortality rate, the formula (1-M) *
BMSY results in an MSST that is very close to the
BMSY. For example, red snapper is a moderately long-lived
fish that has a natural mortality rate of about 0.1. The above formula
results in an MSST of 90 percent of BMSY. In such situations
it can be difficult to determine if a stock is actually less than MSST
due to the imprecision and accuracy of the data used in stock
assessments. In addition, natural fluctuations in stock biomass levels
around the BMSY level may temporarily reduce the stock
biomass to be less than MSST. Setting a greater buffer between
BMSY and MSST can reduce the risk of mistakenly declaring a
stock overfished.
In Amendment 44, the Council evaluated MSSTs ranging from 0.85 *
BMSY (or proxy) to 0.50 * BMSY (or proxy), and
selected 0.50 * BMSY (or proxy) as its preferred
alternative. This is consistent with the National Standard 1 (NS1)
guidelines and reduces the likelihood of a stock being declared
overfished as a result of scientific uncertainty or natural
fluctuations in biomass levels. Setting the MSST at this level could
result in a very restrictive rebuilding plan if the biomass level of a
stock drops below the MSST and NMFS declares that the stock is
overfished. However, the Council determined that the requirements for
overfishing limits (OFLs), annual catch limits (ACLs), and
accountability measures (AMs), reduce the probability that sustained
overfishing would occur and cause a stock to fall below the MSST.
NMFS expects that with the approval of Amendment 44, the Gulf red
snapper and gray triggerfish stocks will be reclassified as not
overfished, but rebuilding, because the biomass for these two stocks is
currently estimated to be greater than 50 percent of BMSY.
The greater amberjack stock will remain classified as overfished.
Procedural Aspects of Amendment 44
Because none of the measures included in the amendment involve
regulatory changes, no proposed or final rule was prepared. The
provisions of Amendment 44 are not specified in regulations but are
considered an amendment to the FMP.
Comments and Responses
NMFS received 23 comments on the NOA. Twelve comments were in favor
of approving the amendment and four were in opposition. Other comments
received were not relevant to Amendment 44, expressing frustration with
fishing regulations and their implementation in general. Comments
specific to the action in Amendment 44 and NMFS' responses to those
comments are summarized below.
Comment 1: NMFS should disapprove Amendment 44 for several reasons.
First, the current MSST definitions appear to be working well and are
not likely to cause stocks from being unnecessarily declared overfished
due to natural variability in fish populations. Second, reducing the
MSST to 0.5 * BMSY will allow these stocks to be further
depleted before they are declared overfished, which will increase the
economic severity of rebuilding and put the stocks at a greater risk of
collapse. Third, there is too much uncertainty in the stock assessments
to lower the MSST and continue to ensure the protection of these
stocks.
Response: NMFS disagrees that Amendment 44 should be disapproved.
Amendment 44 revises the MSST for seven stocks from either 0.75 *
BMSY (hogfish) or (1-M) * BMSY (the other six
species) to 0.5 * BMSY. The National Standard 1 Guidelines
allow the Council to consider a variety of factors is determining the
appropriate MSST (50 CFR 622.310(e)(2)(ii)(B)). In Amendment 44, the
Council considered natural variability in fish populations, the time it
would take a stock to recover from various MSST levels, and the risk of
stock biomass declining below the MSST due to overfishing. The
Southeast Fisheries Science Center (SEFSC) evaluated the likelihood of
stock biomass falling below the MSST due to natural fluctuations. This
evaluation, which is included in Appendix C of Amendment 44, found that
when recruitment and natural mortality estimates are varied, stock
biomass levels declining below MSST at the (1-M) * B BMSY
level for reasons other than overfishing ranged from 5 to 30 percent
depending on a species' life history characteristics. This likelihood
of a stock declining below MSST increases as the as natural mortality
rate decreases. Therefore, the Council determined, and NMFS agrees,
that there is concern that some stocks with
[[Page 61489]]
low natural mortality rates could be determined to be overfished
because of natural variations in the population and the small buffers
between MSST and BMSY.
The SEFSC also analyzed how long it would take stocks with various
life history characteristics to recover from various MSST levels. This
analysis is included in Appendix D of Amendment 44 and found that for
all species analyzed (including red snapper and gray triggerfish),
recovery would occur in the absence of fishing mortality in 10 years or
less under any of the MSST levels, including the MSST of 0.5 *
BMSY. The Council understood that specifying an MSST of 0.5
* BMSY could result in the need for a restrictive rebuilding
plan if a stock was determined to be overfished. However, the Council
determined, and NMFS agrees, that the risk of sustained overfishing
causing a stock to become overfished is minimal given the requirement
to prevent overfishing and use of OFLs, ACLs, and AMs, to achieve this
objective.
With respect to stock assessments, there is a level of uncertainty
in the data used. However, consistent with National Standard 2, these
assessments use the best scientific information available to provide
information on stock status. In addition, for the reasons stated above,
the Council determined that the revised MSSTs, when used in combination
with OFLs, ACLs, and AMs, will continue to provide the appropriate
level of protection for these stocks. Thus, it is not appropriate to
disapprove Amendment 44 based on uncertainty in the stock assessments.
Comment 2: This action to revise the MSST will result in a decrease
in the allowable catch for these stocks.
Response: Revising the MSST will not directly affect catch levels
for the seven stocks in Amendment 44. The MSST is the threshold used to
determine whether a stock is overfished. If the stock biomass falls
below MSST, the stock is considered to be overfished and a rebuilding
plan is required. Therefore, the MSST may indirectly affect catch
levels for a stock if harvest needs to be restricted for some period of
time so the stock can recover. However, of the seven stocks included in
Amendment 44, four are not overfished (gag, red grouper, vermilion
snapper, and hogfish) and that determination will not change with the
revision to the MSSTs for these stocks. The remaining three stocks (red
snapper, gray triggerfish, and greater amberjack) are currently
classified as overfished but, with the approval of Amendment 44, NMFS
expects that red snapper and gray triggerfish stocks will be
reclassified as not overfished. However, they will still be subject to
their respective rebuilding plans until BMSY is reached. The
greater amberjack stock would continue to be classified as overfished
until that stock's biomass exceeds the MSST of 0.5 * BMSY.
Comment 3: NMFS must revisit the previous rulemaking that
implemented the quota overage adjustment (payback) for the red snapper
recreational sector to correct an error in the regulations that links
the recreational payback to ``overfished'' status as opposed to
``rebuilding status.''
Response: NMFS disagrees that it is necessary to revisit the
rulemaking that implemented the red snapper recreational AMs (80 FR
14328, March 19, 2015). The reference to overfished status in the red
snapper recreational AM in 50 CFR 622.41(q)(2)(ii) was not an error.
This provision was added to the regulations through a framework action
in 2015. Although the framework action referred to ``rebuilding,'' the
codified text for the framework that was reviewed and deemed necessary
by the Council linked the quota payback provision to overfished status,
which was consistent with the other payback provisions for Gulf-managed
species that were already in effect prior to that time, such as those
for gray triggerfish (50 CFR 622.41(b)(2)(ii)), gag (50 CFR
622.41(d)(2)(iii)), and red grouper (50 CFR 622.41(e)(2)(iii)).
Although the approval of Amendment 44 may result in the red snapper
stock no longer being classified as overfished because the biomass for
this stock is currently estimated to be greater than 50 percent of
BMSY, the stock continues to be subject to the rebuilding
plan established in Amendment 27 to the FMP (73 FR 5117, January 29,
2008). NMFS is required to review the rebuilding progress at routine
intervals and notify the Council if there has been inadequate progress
toward rebuilding. If notified, the Council would be required to take
action consistent with the rebuilding plan requirements in section
305(e) of the Magnuson-Stevens Act.
In addition, NMFS and the Council have reduced the likelihood of
the red snapper recreational ACL being exceeded by the use of
recreational annual catch targets (ACTs) to set the Federal charter
vessel/headboat (for-hire) and the private angling component
recreational season lengths. However, if an overage of the recreational
ACL does occur more than once in the last 4 years, the National
Standard 1 Guidelines advise the Council to reevaluate the system of
ACLs and AMs, and if necessary, modify the system to improve its
performance and effectiveness (50 CFR 600.310(e)(7)). If the ACL is
exceeded to such an extent that overfishing occurs, the Guidelines
state that the Secretary of Commerce will immediately notify the
Council and the Council should evaluate the cause of overfishing,
address the issue that caused overfishing, and reevaluate the ACLs and
AMs to make sure they are adequate (50 CFR 600.310(j)). All of these
safeguards will help ensure that the ACLs and AMs continue to function
effectively to prevent overfishing and rebuild the stock consistent
with the established rebuilding plan.
