Fisheries of the Caribbean, Gulf of Mexico, and South Atlantic; 
Reef Fish and Red Drum Fisheries of the Gulf of Mexico; Amendments 48/5

AGENCY: National Marine Fisheries Service (NMFS), National Oceanic and 
Atmospheric Administration (NOAA), Commerce.

ACTION: Notice of availability; request for comments.

-----------------------------------------------------------------------

SUMMARY: Combined in a single document, the Gulf of Mexico (Gulf) 
Fishery Management Council (Gulf Council) has submitted Amendment 48 to 
the Fishery Management Plan (FMP) for Reef Fish Resources of the Gulf 
of Mexico and Amendment 5 to the FMP for the Red Drum Fishery of the 
Gulf of Mexico (Amendments 48/5) for review, approval, and 
implementation by NMFS. Amendments 48/5 would establish or modify 
maximum sustainable yield (MSY) proxies, maximum fishing mortality 
thresholds (MFMTs), minimum stock size thresholds (MSSTs), and optimum 
yield (OY) for stocks in the Reef Fish and Red Drum FMPs. The need for 
this action is to have biological reference points that can be used for 
determining status of the stocks or stock complexes consistent with the 
requirements of the Magnuson-Stevens Fishery Conservation and 
Management Act (Magnuson-Stevens Act).

SUPPLEMENTARY INFORMATION: The Magnuson-Stevens Act requires each 
regional fishery management council to submit any FMP or amendment to 
the FMP to NMFS for review and approval, partial approval, or 
disapproval. The Magnuson-Stevens Act also requires that NMFS, upon 
receiving a plan or amendment to the plan, to publish an announcement 
in the Federal Register notifying the public that the FMP or amendment 
to the FMP is available for review and comment.
    Amendments 48/5 were prepared by the Gulf Council and, if approved, 
would be incorporated into the management of Gulf reef fish and red 
drum through the respective FMPs.

Background

    The Magnuson-Stevens Act and the National Standard 1 Guidelines 
require that FMPs specify a number of reference points for managed fish 
stocks, including maximum sustainable yield (MSY) or MSY proxy, and 
optimum yield, as well as status determination criteria (SDC), 
including an MFMT or an overfishing limit (OFL), and an MSST. These SDC 
represent the point at which a stock is determined to be overfished 
(i.e., below MSST) or experiencing overfishing (i.e., above MFMT or 
OFL). In 1999, the Gulf Council submitted the Generic Sustainable 
Fisheries Act (SFA) Amendment, which proposed definitions of MSY, OY, 
MFMT, and MSST for all reef fish stocks. NMFS approved most of the MFMT 
criteria, but disapproved all of the definitions for MSY, OY, and MSST 
because they were not based on biomass.
    While NMFS refers to the document as ``Amendments 48/5'' in this 
notice of availability, each amendment applies separately to the stocks 
in the respective FMPs. Amendment 5 applies to the red drum stock. 
Amendment 48 applies to several reef fish stocks and stock complexes 
that either have not been assessed or were assessed but still require 
stock status determinations. These include: Cubera snapper, lane 
snapper, goliath grouper, the shallow-water grouper complex (scamp, 
black grouper, yellowmouth grouper, and yellowfin grouper), the deep-
water grouper complex (yellowedge grouper, warsaw grouper, snowy 
grouper, and speckled hind), the tilefish complex (golden tilefish, 
blueline tilefish, and goldface tilefish), the jacks complex (lesser 
amberjack, almaco jack, and banded rudderfish), and the mid-water 
snapper complex (wenchman, silk snapper, blackfin snapper, and queen 
snapper). Amendments 48/5 also addresses four reef fish stocks that 
have been assessed and have known stock status determinations: Hogfish, 
mutton snapper, yellowtail snapper, and black grouper. Amendment 43 to 
the Reef Fish FMP established references points and SDC for hogfish. 
However, OY for hogfish was not defined there and is addressed in 
Amendments 48/5. Mutton snapper, yellowtail snapper, and black grouper, 
which occur in both the Gulf Council and South Atlantic Fishery 
Management Council areas of jurisdiction but are managed separately 
under each Council's FMPs, have reference points and SDC specified in 
the South Atlantic Snapper-Grouper FMP, but not in the Gulf Reef Fish 
FMP. With respect to black grouper, that species is managed by the 
South Atlantic Council as a single stock but is managed by the Gulf 
Council as part of the shallow-water grouper complex.

Maximum Sustainable Yield

    The MSY is the largest long-term average catch or yield that can be 
taken from a stock or stock complex under

[[Page 13275]]

prevailing ecological, environmental conditions and fishery 
technological characteristics (e.g., gear selectivity), and the 
distribution of catch among fleets. However, the actual MSY can rarely 
be estimated with certainty because of the difficulty in accurately 
estimating the relationship between the size of the spawning stock and 
the subsequent annual recruitment. As a result, proxies for MSY are 
typically used because they are easier to measure. Generally, MSY 
proxies used for fish species in the Gulf are based on some percentage 
of spawning potential ratio (SPR) and are expressed as the yield when 
fishing at FPROXY (where F is fishing mortality rate). In 
using SPR, NMFS assumes that a certain amount of fish must survive and 
spawn in order to replenish the stock, thus SPR represents the average 
number of eggs per fish over its lifetime when the stock is fished, 
compared to the average number of eggs per fish over its lifetime when 
the stock is not fished. A sustainable SPR depends on the life history 
of the species, but in general, is between 20 percent and 40 percent 
for reef fish species. The advantage of using SPR as a proxy is that it 
requires less information to calculate than MSY.
    For reef fish stocks and stock complexes with the exception of 
goliath grouper, the MSY proxy selected by the Gulf Council is the 
yield when fishing at F30% SPR. This is the proxy most commonly 
recommended by the Gulf Council's SSC for assessed reef fish stocks and 
the SSC recommended this MSY proxy for the reef fish stocks and stock 
complexes in Amendment 48. For goliath grouper, the Gulf Council 
selected a more conservative MSY proxy because this species is more 
vulnerable to overfishing because of its long life-span and slow growth 
rate. The goliath grouper MSY proxy is the yield when fishing at F40% 
SPR. The MSY proxies for goliath grouper, mutton snapper and yellowtail 
snapper are consistent with MSY proxy selected by the South Atlantic 
Council.
    The harvest of red drum is prohibited in Federal waters, but 
fishing is allowed in state waters under management measures developed 
by the respective Gulf state marine fisheries agencies. These agencies 
manage the stock to achieve a 30 percent escapement rate from state to 
Federal waters. Thus, Amendments 48/5 would define the red drum MSY 
proxy as the yield that provides for an escapement rate of juvenile 
fish to the spawning stock biomass (SSB) equivalent to 30 percent of 
those that would have escaped had there been no inshore state-waters 
fishery.
    Amendments 48/5 would also adopt a streamlined procedure for future 
specification of the MSY proxies for reef fish stocks and red drum. 
This procedure would allow the Gulf Council to adopt an MSY proxy 
recommended by the SSC by including a discussion of the change in a 
plan amendment. If the Council chooses to use this procedure, which 
would not include the consideration of alternatives to the MSY proxy 
recommended by the SSC, NMFS expects the Council to document its 
rationale for that decision. If more than one MSY proxy is supported by 
the best scientific information available, NMFS expects the Council to 
provide an appropriate analysis of these alternatives.

Maximum Fishing Mortality Thresholds

    MFMT is the rate of fishing mortality above which a stock is 
experiencing overfishing. Overfishing can also be determined using the 
OFL, which is the annual amount of catch that corresponds to fishing at 
MFMT. Consistent with the Generic Annual Catch Limits and 
Accountability Amendment, NMFS uses the MFMT to determine overfishing 
for stocks or stock complexes that have stock assessments only in years 
in which a stock assessment is conducted. For other years, and for 
stocks or stock complexes without stock assessments, NMFS uses catch 
compared to the OFL to determine overfishing.
    The Generic SFA Amendment set MFMT equal to F50% SPR for goliath 
grouper, equal to F30% SPR for red drum, and equal to F30% SPR for all 
reef fish stocks except red snapper (MFMT = F26% SPR). To keep MFMT 
consistent with the proposed MSY proxies, Amendments 48/5 would set 
this threshold for the relevant stocks equal to the F at the MSY proxy 
for each stock or stock complex as discussed above.

Minimum Stock Size Thresholds

    The MSST is a biomass reference point that measures how many fish 
are left in the water rather than how many fish are caught, and 
determines at what biomass level a stock or stock complex is 
overfished. The MSST can be specified in terms of pounds of fish, 
numbers of fish, or the expected egg production from the SSB of the 
adult stock. The long-term average size of a stock that results from 
harvesting at MSY is called the biomass at MSY (BMSY). If 
the stock level falls below BMSY, it cannot sustain harvest 
at the MSY level without further depletion. However, biomass may 
fluctuate over time because of changes in environmental conditions, 
recruitment to the stock, or other variables. Because of these natural 
fluctuations, the MSST is generally set at some level below 
BMSY, but cannot be set lower than 50 percent of 
BMSY. The greater the difference between BMSY and 
MSST, the less likely a stock is to be declared overfished, but the 
more difficult it may be to rebuild the stock back to BMSY 
should the stock size fall below MSST.
    In Amendments 48/5 the Council considered several alternatives for 
MSST that would apply to all of the stocks and stock complexes for 
which the Council is also establishing MSY and MFMT. These alternatives 
ranged from (1-M)*BMSY (or proxy), where M is the natural 
mortality, to 0.50*BMSY (or proxy), and the Council chose to 
set MSST for these stocks and stock complexes at 0.75*BMSY 
(or proxy). This value is between the BMSY (or proxy) stock 
level and the 50 percent of BMSY (or proxy) level used by 
the Gulf Council for assessed reef fish stocks as defined in Amendment 
44 to the Reef Fish FMP. The Gulf Council determined that this more 
conservative value is appropriate for the unassessed stocks and stock 
complexes addressed in Amendments 48/5. The Council also considered and 
selected an additional alternative that would apply only to those 
individual stocks that span both the South Atlantic and Gulf Councils' 
areas of jurisdiction and would set MSST consistent with the MSST 
specified by the South Atlantic Council. These stocks are goliath 
grouper, black grouper, mutton snapper, and yellowtail snapper. The 
MSST specified by the South Atlantic Council is 0.75*BMSY 
(or proxy) for black grouper, mutton snapper, and yellowtail snapper, 
and (1-M)*BMSY (or proxy) for goliath grouper.
    As discussed previously, and unlike the South Atlantic Council, the 
Gulf Council manages black grouper as part of the shallow water grouper 
complex, not as a single stock. Therefore, although black grouper was 
included in preferred alternative 5 that addressed the other three 
stocks that span both the South Atlantic and Gulf Councils' areas of 
jurisdiction, Amendment 48 does not consider specifying an MSY for 
black grouper as a single stock. Instead, consistent with the Gulf 
Council's current management of this stock, Amendment 48 would specify 
an MSY for the entire shallow-water grouper complex, which includes 
black grouper. NMFS invites specific comments on the part of Amendments 
48/5 that proposes to specify MSST for black grouper as a single stock.

Optimum Yield

    The Magnuson-Stevens Act and NS1 guidelines state that OY is based 
on MSY as reduced by relevant economic, social, or ecological factors. 
Additionally, the NS1 guidelines state that OY should include some 
consideration of uncertainty. If the estimates of MFMT and current 
biomass are known with a high level of certainty, and management 
controls can accurately limit catch, then OY could be set very close to 
MSY, assuming no other reductions are necessary for social, economic, 
or ecological factors. However, OY cannot exceed MSY. To the degree 
that such MSY estimates and management controls are lacking or 
unavailable, OY should be reduced farther from MSY.
    For the assessed reef fish stocks that are not addressed in 
Amendments 48/5, the Gulf Council has defined OY as the yield from 
fishing at some percentage of FMSY (or proxy). However, the 
NMFS Southeast Fisheries Science Center (SEFSC) staff and the Gulf 
Council's SSC have recommended against specifying OY as the yield at a 
certain value of F. They have suggested instead that OY be a percentage 
of MSY for three reasons: (1) If OY is specified as a percentage of 
FMSY (or proxy), SEFSC staff would need to provide two sets 
of yield projections when running stock assessments (one for MSY and 
one for OY), adding complexity to the projections; (2) it is possible 
that the calculated long-term yield at the FOY proxy could 
be greater than the calculated long-term yield at the FMSY 
proxy, which would be inconsistent with the Magnuson-Stevens Act and 
NS1 guidelines; and (3) defining OY as a percent of MSY is more 
intuitive and easier to understand than using a percentage of the 
FMSY proxy to define OY. Therefore, the Gulf Council 
proposes setting OY at 90 percent of the MSY or MSY proxy for all reef 
fish stocks addressed in Amendments 48/5 with the exception of goliath 
grouper.
    For goliath grouper, the Council proposes using the ratio between 
the annual catch limit (ACL) and OFL to determine how much the OY 
should be reduced from the MSY. This relationship accounts for 
scientific and management uncertainty and would apply that knowledge to 
guide where OY should be set relative to MSY for this stock. Because 
possession of goliath grouper is prohibited, the OY value would be 
zero.
    For red drum, the Gulf Council decided to keep the existing OY 
definition, which is based on a 1987 SEFSC stock assessment that 
concluded under certain escapement rates of juveniles, the stock could 
rebuild. This OY definition is: (1) All red drum commercially and 
recreationally harvested from Gulf state waters landed consistent with 
state laws and regulations under a goal of allowing 30 percent 
escapement of the juvenile population; and (2) all red drum 
commercially or recreationally harvested from the Primary Area 
(Louisiana, Mississippi, and Alabama) of the exclusive economic zone 
(EEZ) under the total allowable catch (TAC) level and allocations 
specified under the provisions of the Red Drum FMP, and a zero-
retention level from the Secondary Areas (Florida and Texas) of the 
EEZ. The red drum TAC for the Gulf EEZ has been zero since 1988 with 
the implementation of Amendment 2 to the Red Drum FMP and harvest in 
the EEZ is prohibited (53 FR 34662; June 29, 1988). Therefore, to 
achieve the OY, the Gulf states have independently and cooperatively 
implemented red drum regulations to achieve a 30 percent or greater 
escapement rate to the spawning stocks for each year class.

Procedural Aspects of Amendments 48/5

    The Council has submitted Amendments 48/5 for Secretarial review, 
approval, and implementation. NMFS' decision to approve, partially 
approve, or disapprove Amendments 48/5 will be based, in part, on 
consideration of comments, recommendations, and information received 
during the comment period on this notice of availability. After 
consideration of these factors, and consistency with the Magnuson-
Stevens Act and other applicable laws, NMFS will publish a notice of 
agency decision in the Federal Register announcing the Agency's 
decision to approve, partially approve, or disapprove Amendments 48/5. 
Because none of the measures included in the amendments involve 
regulatory changes, no proposed or final rule is required at this time. 
If approved, the provisions of Amendments 48/5 would not be specified 
in regulations but would be considered amendments to the respective 
FMPs.

Consideration of Public Comments

    Comments on Amendments 48/5 must be received by May 9, 2022. 
Comments received during the comment period for this notice of 
availability will be considered by NMFS in its decision to approve, 
partially approve, or disapprove Amendments 48/5. Comments received 
after the comment period will not be considered by NMFS in this 
decision. All comments received by NMFS during the comment period will 
be addressed in the notice of agency decision.
