Fisheries of the Caribbean, Gulf of Mexico, and South Atlantic; 
Shrimp Fishery of the Gulf of Mexico; Amendment 10

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

ACTION: Proposed rule; request for comments.

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

SUMMARY: NMFS issues this proposed rule to implement Amendment 10 to 
the Fishery Management Plan for the Shrimp Fishery of the Gulf of 
Mexico (Amendment 10), as prepared and submitted by the Gulf of Mexico 
Fishery Management Council (Council). This proposed rule would require, 
with limited exceptions, the use of NMFS-certified bycatch reduction 
devices (BRDs) in shrimp trawls in the Gulf of Mexico exclusive 
economic zone (Gulf EEZ) east of 85[deg]30' W. long. (approximately 
Cape San Blas, FL). In addition, this proposed rule would identify the 
certified BRDs currently authorized for use in the Gulf EEZ east of 
85[deg]30' W. long. and would modify the Gulf Of Mexico Bycatch 
Reduction Device Testing Protocol Manual to reflect the specific 
bycatch reduction criterion applicable for certification of BRDs used 
in this area of the Gulf EEZ. The intended effect of this proposed rule 
is to reduce bycatch in the Gulf of Mexico shrimp fishery to the extent 
practicable.

DATES: Comments must be received no later than 4:30 p.m., eastern time, 
on November 14, 2003.

ADDRESSES: Written comments on the proposed rule should be sent to Dr. 
Steve Branstetter, Southeast Regional Office, NMFS, 9721 Executive 
Center Drive N., St. Petersburg, FL 33702. Comments also may be sent 
via fax to (727) 570-5583. Comments will not be accepted if submitted 
via e-mail or Internet.
    Requests for copies of Amendment 10, which includes an 
environmental assessment, regulatory impact review (RIR), initial 
regulatory flexibility analysis (IRFA), and a social impact assessment 
should be sent to the Gulf of Mexico Fishery Management Council, 3018 
U.S. Highway 301 North, Suite 1000, Tampa, FL 33619-2266; telephone:

SUPPLEMENTARY INFORMATION: The fishery for shrimp in the Gulf EEZ is 
managed under the Fishery Management Plan for the Shrimp Fishery of the 
Gulf of Mexico (FMP). The FMP was prepared by the Council, approved by 
NMFS, and implemented under the authority of the Magnuson-Stevens 
Fishery Conservation and Management Act (Magnuson-Stevens Act) by 
regulations at 50 CFR part 622.

Background

    The Magnuson-Stevens Act requires that fishery management plans 
establish a standardized reporting methodology to assess the amount and 
type of bycatch occurring in the fishery, and include measures that 
minimize bycatch and minimize the mortality of bycatch which cannot be 
avoided. Previously, the Council prepared, and NMFS approved and 
implemented (63 FR 18139, April 14, 1998), Amendment 9 to the FMP to 
address bycatch in the Gulf shrimp fishery in the western Gulf. 
Amendment 9 focused primarily on reducing the shrimp trawl bycatch of 
juvenile red snapper and required use of NMFS-certified BRDs, with 
limited exceptions, shoreward of the 100-fathom (fm)(183-m) depth 
contour west of 85[deg]30' W. long. Bycatch of juvenile red snapper 
occurs principally in the western Gulf. Amendment 10 and this proposed 
rule would extend the requirement for use of appropriately certified 
BRDs to the eastern Gulf to further reduce shrimp trawl bycatch in 
compliance with the Magnuson-Stevens Act requirements.

BRD Requirement

    Amendment 10 specifies that the bycatch reduction criterion for 
certification of a BRD to be used in the Gulf EEZ east of 85[deg]30' W. 
long. is a minimum of 30-percent reduction, by weight, of finfish 
bycatch. This proposed rule would require a shrimp trawler in the Gulf 
EEZ east of 85[deg]30' W. long., the approximate longitude of Cape San 
Blas, FL, to have an appropriate NMFS-certified BRD installed in each 
net rigged for fishing. A shrimp trawler is defined as any vessel that 
is equipped with one or more trawl nets whose on-board or landed catch 
of shrimp is more than 1 percent, by weight, of all fish comprising its 
on-board or landed catch.
    Currently available BRDs that would meet the applicable bycatch 
reduction criterion for the eastern Gulf and would be certified for use 
in that area include: Fisheye, Gulf Fisheye, Jones-Davis, Extended 
funnel, and Expanded mesh. Descriptions of these BRDs and minimum 
construction and installation requirements are provided in 50 CFR part 
622 appendix D. As additional BRDs are tested and certified by NMFS, 
they would be added to the list of certified BRDs by publication of a 
notice in the Federal Register.
    This proposed rule would exempt the following gear from the BRD 
requirement: (1) A single try net with a headrope length of 16 ft (4.9 
m) or less; (2) up to two rigid-frame roller trawls of 16 ft (4.9 m) or 
less; (3) vessels trawling for royal red shrimp (i.e., provided that at 
least 90 percent of all shrimp on board or offloaded are royal red 
shrimp); and (4) vessels trawling for groundfish

[[Page 56253]]

or butterfish. The Council has concluded that finfish bycatch 
associated with such gear or activities is likely to be minimal and 
that the costs associated with the BRD requirement would not be 
justified in such cases.

Standardized Bycatch Reporting

    To address the Magnuson-Stevens Act requirement for a standardized 
bycatch reporting methodology, Amendment 10 proposes to use the annual 
Summer Shrimp/Groundfish and Fall Shrimp/Groundfish Trawl Surveys to 
determine annual finfish and invertebrate bycatch in the Gulf shrimp 
fishery. Trawls used in these research surveys are not equipped with 
BRDs. Because shrimp trawlers are currently required to use BRDs in the 
western Gulf, and this rule proposes to require them in the eastern 
Gulf as well, estimates of bycatch from the research surveys would be 
reduced by at least 35 percent (the estimated bycatch reduction 
achieved by the most commonly used Fisheye BRD). The surveys' sampled 
bycatch data would then be converted into 24-hour (or per-day) 
estimates. These results would then be multiplied by the same year's 
estimated shrimp effort data, in days fished, to obtain annual 
estimates of total finfish and invertebrate bycatch.

Minor Revisions to the Gulf Of Mexico Bycatch Reduction Device Testing 
Protocol Manual

    The current protocol manual was written to address testing and 
certification of BRDs based on a bycatch reduction criterion related to 
reduction of bycatch of juvenile red snapper in the western Gulf. 
Amendment 10 addresses bycatch in the eastern Gulf and establishes a 
different bycatch reduction criterion for evaluating BRDs to be used in 
that area, i.e., a minimum of a 30-percent reduction, by weight, of 
finfish bycatch. This proposed rule would revise the appended protocol 
manual to distinguish, where necessary, the different criteria that 
would apply to BRD testing and certification in the specified eastern 
and western Gulf areas.

Additional Information

    Additional background and rationale for the measures discussed here 
are contained in Amendment 10, the availability of which was announced 
in the Federal Register (68 FR 48592; August 14, 2003). The public 
comment period on Amendment 10 expires on October 14, 2003. All 
comments received on Amendment 10 or on this proposed rule during their 
respective comment periods will be addressed in the preamble to the 
final rule.

Classification

    At this time, NMFS has not determined that Amendment 10 that this 
proposed rule would implement is consistent with the national standards 
of the Magnuson-Stevens Act and other applicable laws. In making that 
determination, NMFS will take into account the data, views, and 
comments received during the comment period on Amendment 10 and this 
proposed rule.
    This proposed rule has been determined to be not significant for 
purposes of Executive Order 12866.
    The Council prepared an IRFA that describes the economic impact 
this proposed rule, if adopted, would have on small entities. 
Subsequently, NMFS prepared a supplement to the IRFA to clarify and 
correct information contained within the analyses of the social and 
economic impacts of the options in the proposed amendment, and to 
update the data used in these analyses. A description of the action, 
why it is being considered, and the legal basis for this action are 
contained at the beginning of this section in the preamble and in the 
SUMMARY section of the preamble. A summary of the analyses follows.
    As amended, the Magnuson-Stevens Act provides the statutory basis 
for the proposed rule. The objective of this amendment is to further 
reduce bycatch in the Gulf shrimp fishery to the extent practicable. 
The proposed rule will require the use of BRDs in all NMFS statistical 
zones of the eastern Gulf of Mexico EEZ.
    No duplicative, overlapping, or conflicting Federal rules have been 
identified.
    In 2001, approximately 946 shrimp trawl fishing craft were known to 
operate in statistical areas 1 through 8 off the west coast of Florida. 
Within this group of affected entities, 460 operate in statistical 
areas 1 through 3, 283 operate in statistical areas 4 and 5, and 592 
operate in statistical areas 6 through 8. Of the 946 shrimp trawlers 
affected by this proposed action, 736 craft are Coast Guard registered 
vessels and 210 are state registered boats; 474 are considered large 
vessels, while 472 are considered small vessels/boats; 868 (91.8 
percent) shrimp trawlers landed shrimp in Florida, 102 landed shrimp in 
Alabama, 4 landed shrimp in Mississippi, and 31 landed shrimp in Texas; 
49 landed in both Florida and Alabama, 7 landed in both Florida and 
Texas, and 1 each landed in Mississippi/Florida and Alabama/Texas.
    Overall, average revenue per shrimp trawler from areas 1 through 8 
is $26,440. Average total costs per shrimp trawler are $38,991, 
resulting in an average annual loss of $12,551. The average number of 
crew is 2.3 for small shrimp trawlers and 3.5 for large shrimp 
trawlers, resulting in an overall average of 2.9 crew per trawler. Each 
small trawler is assumed to use two nets, each large trawler is assumed 
to use 4 nets, and, in each case, each trawler is assumed to have at 
least one spare set of nets on board. A commercial fishing business is 
considered a small business entity if its annual gross revenues are 
less than or equal to $3.5 million. Based on the average revenue 
information provided above, all harvesting operations within this 
fishery can be considered to be small business entities.
    Additionally, 61 shrimp dealers would be affected by the proposed 
actions. Average Gulf shrimp purchases per dealer is $2,029,221, with 
an average of $692,622 coming from harvests in areas 1 through 8. The 
average number of employees per dealer is 37.
    A substantial number of small entities will be affected by the 
proposed action, regardless of whether the entire universe of Florida 
west coast shrimp trawlers or only certain groups within that universe 
(e.g., shrimp trawlers that operate in lower Florida or large shrimp 
trawlers that land in Florida) is considered. That is, the total number 
of affected shrimp trawlers are those who participate in the west 
Florida shrimp fishery, which is 946. Of those 946 shrimp trawlers, 868 
land in Florida and 399 are specifically large shrimp trawlers that 
land in Florida. Any of these estimates would be considered a 
substantial number of small entities though the primary economic 
impacts of the proposed action are on the latter group. The total 
number of shrimp trawlers operating in the entire Gulf of Mexico is not 
the appropriate universe for determining whether the substantial number 
criterion has been met, or whether the impacts to small entities are 
significant, since only those entities operating in areas 1 through 8 
off the Florida west coast will be impacted by the proposed action.
    Employment data within the dealer sector are sparse. However, for 
12 of the affected shrimp dealers, the number of employees ranged from 
1 to 168, with an average of 37 employees, based on the most recently 
available data. Further, only the single largest shrimp processor in 
the Gulf employed more than 500 workers on average per year. Since 
shrimp dealers are typically smaller operations than shrimp processors 
in terms of volume and employment, it can be assumed that all dealers 
affected by the proposed action

[[Page 56254]]

employ less than 500 workers per year on average. A dealer is 
considered a small business entity if it employs less than or equal to 
500 employees. All of the 61 affected shrimp dealers can, therefore, be 
considered to be small business entities.
    Since all shrimp harvest and dealer operations affected by the 
proposed action are considered to be small business entities, the issue 
of disproportionate effects between large and small entities does not 
arise.
    NMFS' analysis indicates that the average revenue per shrimp 
trawler is $26,440, and the average annual profit is negative, equaling 
a loss of $12,511. Under the proposed action, the average reduction in 
revenue and profits per shrimp trawler would be $1,444 and $1,112, 
which represent reductions of 5.5 percent and 8.9 percent respectively. 
Although these figures can be broken down according to various 
criteria, such as vessel size category, state of landing, and area of 
fishing, they are generally representative of the analysis' results and 
need not be presented in this summary. The detailed break-outs are 
provided in the IRFA.
    In order for a firm to continue operating in the short-run, 
revenues must at least cover variable costs. Due to the relatively 
large losses throughout the west Florida shrimp fishery, many shrimp 
trawlers cannot apparently currently cover their variable costs and 
additional regulatory burdens at the levels noted above will accelerate 
the rate at which these vessels' operations are forced to shut down. It 
is not possible at this time, however, to accurately determine how many 
more of these operations will in fact shut down as a result of the 
proposed actions.
    In terms of the value of shrimp purchases, the loss per dealer is 
estimated to be $22,393, which represents an average of 1.1 percent for 
all dealers, but 2 percent for dealers in Florida. Since profitability 
is unknown in this sector, the significance of such losses cannot be 
determined with certainty. However, given that the number of dealers 
purchasing shrimp from the west Florida fishery declined from 84 in 
1998 to 61 in 2001, and the poor economic health of the harvesting 
sector, it is logical to assume that losses are being incurred in the 
dealer sector. Dealers in Key West, Ft. Myers Beach, Tampa, St. 
Petersburg, and Tarpon Springs would likely be most susceptible to 
potential impacts of the proposed action.
    Significant alternatives to the proposed action include area 
closures, seasonal closures, and modifications to BRD requirements. 
With respect to area and seasonal closures, the proposed action is to 
retain the status quo and thus would impose no adverse economic impacts 
on small entities. With regards to BRD requirements, two alternatives 
would require BRDs over the identical geographic range, statistical 
areas 1 through 8, as the proposed action and, thus would not reduce 
the expected negative economic impacts. Two alternatives would limit 
the BRD requirement to statistical areas 4 through 8, which would 
significantly reduce the negative economic impacts attributable to the 
proposed action. Two other alternatives, the status quo, which would 
not require BRDs, and an alternative that would limit the requirement 
to statistical areas 6 through 8 would further reduce the negative 
economic impacts of the proposed action. However, none of these 
alternatives would satisfy the requirement and Councils' intent to 
minimize bycatch ``to the extent practicable.'' Of the various 
alternatives that require BRDs, the proposed action would accomplish 
the greatest total bycatch reduction since BRDs would be required over 
a greater geographic range. Requiring BRDs over the entire area 
(statistical areas 1-8) would result in the bycatch reduction of 
approximately 4.006 million pounds, whereas requiring BRDs in only 
statistical areas 4-8 would result in the bycatch reduction of 
approximately 1.91 million pounds.
    In conclusion, the proposed action is expected to create a 
significant and adverse economic impact on a substantial number of 
small entities. These impacts are likely even greater for shrimp 
trawlers that operate primarily or exclusively in lower Florida, 
particularly large shrimp trawlers. For these operations, the 
percentage increase in annual losses due to the proposed action likely 
ranges from 9.2 percent to as much as 23.4 percent. Although the impact 
on shrimp dealers is not as large in percentage terms (1.1 percent to 2 
percent), the impact on this group of small entities is also likely 
significant, given the high probability that losses are also being 
incurred in this sector.

Appendix--Gulf Of Mexico Bycatch Reduction Device Testing Protocol 
Manual

Definitions

    Bycatch reduction criterion means--
    (1) In the Gulf EEZ west of 85[deg]30' W. long., that the BRD 
reduces the mortality of juvenile (age 0 and age 1) red snapper by a 
minimum of 44 percent from the average level of bycatch mortality 
(F=2.06) on these age classes during the years 1984-1989.
    (2) In the Gulf EEZ east of 85[deg]30' W. long., that the BRD 
reduces the bycatch of total finfish by at least 30 percent by 
weight.
    Bycatch reduction device (BRD) is any gear or trawl modification 
designed to allow finfish to escape from a shrimp trawl.
    BRD candidate is a bycatch reduction device to be tested for 
certification for use in the commercial shrimp fishery of the Gulf 
of Mexico.
    Catch per unit of effort (CPUE) means the number or pounds of 
fish (e.g., red snapper) or shrimp taken during a pre-defined 
measure of fishing activity (e.g., per hour).
    Certification phase is a required testing phase whereby an 
individual so authorized by the RA may conduct a discrete testing 
program, with a sample size adequate for statistical analysis (no 
less than 30 tows), to determine whether a BRD candidate meets the 
bycatch reduction criterion.
    Certified BRD is a BRD that has been tested according to this 
protocol and has been determined by the RA as having met the bycatch 
reduction criterion.
    Control trawl means a trawl used during the certification 
testing that is not equipped with a BRD. The catch of this trawl is 
compared to the catch of the experimental trawl.
    Experimental trawl means the trawl used during the certification 
tests that is equipped with the BRD candidate.
    Evaluation and oversight personnel includes scientists, 
observers, and other technical personnel who, by reason of their 
occupational or other experience, scientific expertise or training, 
are approved by the RA as qualified to evaluate and oversee the 
application and testing process. Scientists and other technical 
personnel will (1) review a BRD certification test application for 
its merit, and (2) critically review the scientific validity of the 
certification test results.
    Observer means a person on the list maintained by the RA of 
individuals qualified to supervise and monitor a BRD certification 
test. Applicants may obtain the list of individuals qualified to be 
an observer from the RA. The observer chosen by the applicant may 
not have any current or prior financial relationship with the entity 
seeking BRD certification. For information on observer qualification 
criteria and the observer application process, see Appendix I.
    Pre-certification phase is an optional testing phase whereby an 
individual, so authorized by the RA, can experiment with the design, 
construction, and configuration of a BRD and gather data.
    Regional Administrator (RA) means the Southeast Regional 
Administrator, National Marine Fisheries Service, 9721 Executive 
Center Drive North, St. Petersburg, FL 33702, phone 727-570-5301.
    Required measurements refers to the quantification of the 
dimensions and configuration of the trawl, the BRD candidate, the 
doors, the location of the BRD in relation to other parts of the 
trawl gear, and other quantifiable criteria used to assess the 
performance of the BRD candidate.
    Sample size means the number of successful tows (a minimum of 30 
tows per test are required).
    Shrimp loss means the percent difference in average CPUE (e.g. 
kg/hr) between the amount of shrimp caught in the control trawl and 
the amount of shrimp caught in the experimental trawl.
    Successful tow means that the control and experimental trawl 
were fished in accordance with the requirements set forth in the 
protocol and the terms and conditions of the letter of 
authorization; that no indication exists that problematic events, 
such as those listed in Appendix D-5, occurred during the tow which 
would impact or influence the fishing efficiency (catch) of one or 
both nets; and, in the Gulf EEZ west of 85[deg]30' W. long., that 
the control or experimental net caught at least five red snapper 
during the tow.
    Tow time means the total time (hours and minutes) an individual 
trawl was fished while being towed (i.e., the time between ``dog-
off'' and start of haul back).
    Trawl means a net and associated gear and rigging, as 
illustrated in Appendix B-5 of this manual, used to catch shrimp. 
The terms trawl and net are used interchangeably throughout the 
manual.
    Tuning a net means adjusting the trawl and its components to 
minimize the differences in shrimp catch between the two nets that 
will be used as the control and experimental trawls during the 
certification tests.

I. Introduction

Purpose of the Protocol

    This protocol sets forth a standardized scientific procedure for 
the testing of a BRD candidate and for the evaluation of its ability 
to meet the bycatch reduction criterion. For a BRD candidate to be 
certified by the RA, the BRD candidate must meet the bycatch 
reduction criterion.
    There are two phases to this procedure: An optional, but 
recommended, pre-certification phase and a required certification 
phase. An applicant is encouraged to take advantage of the pre-
certification phase which allows experimentation with different BRD 
designs and configurations prior to certification phase testing (see 
below for details). The certification phase requires the applicant 
to conduct a discrete testing program, with a sample size of no less 
than 30 tows to determine whether the BRD candidate meets the 
bycatch reduction criterion. There is no cost to the applicant for 
the RA's administrative expenses such as preparing applications, 
issuing letters of authorization (LOAs), or evaluating test results 
or certifying BRDs. However, all other costs associated with either 
phase (e.g., field testing) are at the applicant's expense.

II. Pre-Certification Phase (Optional)

    The pre-certification phase provides a mechanism whereby an 
individual can experiment with the design, construction, and 
configuration of a prototype BRD for up to 60 days to improve the 
design's effectiveness at reducing bycatch and to determine whether 
it is likely to meet the bycatch reduction criterion. To conduct 
pre-certification phase evaluations of a prototype BRD, the 
applicant must apply for, receive, and have on board the vessel 
during testing, an LOA from the RA.

A. Application

    In order to obtain an LOA to conduct pre-certification phase 
evaluations of a prototype BRD, an individual must submit a complete 
application to the RA. A complete application consists of a 
completed application form, Application to Test A Bycatch Reduction 
Device in the Exclusive Economic Zone (the form is appended as 
Appendix J-1), and the following: (1) a brief statement of the 
purpose and goal of the activity for which the LOA is requested; (2) 
a statement of the scope, duration, dates, and location of the 
testing; (3) an 8.5-inch x 11-inch (21.6-cm x 27.9-cm) diagram drawn 
to scale of the BRD design; (4) an 8.5-inch x 11-inch (21.6-cm x 
27.9-cm) diagram drawn to scale of the BRD and approved TED in the 
shrimp trawl; (5) a description of how the BRD is supposed to work; 
(6) a copy of the testing vessel's documentation or its state 
registration; and (7) a copy of the vessel's Federal shrimp permit.
    An applicant requesting a pre-certification LOA of an unapproved 
hard or soft TED as a BRD must first apply for and obtain from the 
RA an experimental TED authorization pursuant to 50 CFR 223.207(e). 
The pre-certification phase LOA application must also append a copy 
of that authorization.

[[Page 56256]]

B. Issuance

    The RA will review the application for completeness. If the 
application is incomplete, the RA will inform the applicant of the 
incompleteness and give the applicant an opportunity to cure. If 
incompleteness is not cured within 30 days, the application will be 
returned to the applicant. Upon receipt of a complete application, 
the RA will issue a LOA to conduct pre-certification phase testing 
upon the vessel specified in the application if the BRD design is 
substantially unlike BRD designs previously determined not to meet 
the current performance criterion, or if the design is substantially 
similar to BRD designs previously determined not to meet the current 
performance criteria and the application demonstrates that the 
design could meet the bycatch reduction criterion through design 
revision or upon retesting (e.g., the application shows that 
statistical results could be improved upon retesting by such things 
as a larger sample size than that previously used). If a pre-
certification phase LOA is denied, the RA will return the 
application to the applicant along with a letter of explanation 
including relevant recommendations as to curing the deficiencies 
which caused the denial. In arriving at a decision, the RA may 
consult with evaluation and oversight personnel. Issuance of a LOA 
allows the applicant to remove or disable the existing BRD in one 
net (to create a control net), and to place the prototype BRD in 
another net in lieu of a certified BRD (to create an experimental 
net). All other trawls under tow during the test must be equipped 
with a certified BRD. All trawls under tow during the pre-
certification phase tests must be equipped with an approved TED 
unless operating under an authorization issued pursuant to 50 CFR 
223.207(e). The LOA, and experimental TED authorization if 
applicable, must be on board the vessel while the pre-certification 
phase tests are being conducted. The term of the LOA will be 60 
days.

C. Applicability

    The pre-certification phase allows an individual to compare the 
catches of a control net to the catches of the experimental net (net 
equipped with the prototype BRD) to estimate the potential 
efficiency of the prototype BRD. If that individual subsequently 
applies for a certification phase LOA to test this design, he/she 
must include the results of the pre-certification phase evaluation 
with the certification application. The RA will use this information 
to determine if there is a reasonable scientific basis to conduct 
certification phase testing. Therefore, for each paired tow, the 
applicant should keep a written record of the weight of the shrimp 
catch, the weight of the finfish catch, and, if the testing is 
related to potential certification of the BRD for use in the Gulf 
EEZ west of 85[deg]30' W. long., the total catch (in numbers) of red 
snapper of each net. The form contained in Appendix D should be used 
to record this information.

III. Certification Phase (Required)

    In order to have a BRD certified, it must, under certification 
phase testing, be consistent with the requirements of the testing 
protocol and LOA and be determined by the RA to meet the bycatch 
reduction criterion.

A. Application

    To conduct certification phase testing, an individual must 
obtain a certification phase LOA. To obtain a certification phase 
LOA, an individual must submit a complete application to the RA. The 
complete test application consists of an Application to Test A 
Bycatch Reduction Device in the Exclusive Economic Zone (Appendix J-
1), a copy of the vessel's current Coast Guard certificate of 
documentation or, if not documented, its state registration 
certificate; a copy of the vessel's Federal shrimp permit; the name 
of a qualified observer who will be on board the vessel during all 
certification test operations (see Appendix I); and a test plan 
showing: (1) An 8.5-inch x 11-inch (21.6-cm x 27.9-cm) diagram drawn 
to scale of the BRD candidate; (2) an 8.5-inch x 11-inch (21.6-cm x 
27.9-cm) diagram drawn to scale of the BRD candidate and approved 
TED in the shrimp trawl; (3) a description of how the BRD candidate 
is supposed to work; (4) the results of previous pre-certification 
phase tests; (5) the location, time, and area where the 
certification phase tests would take place; and (6) the identity of 
the observer from the list of qualified individuals maintained by 
the RA and certification that the observer has no current or prior 
financial relationship with the applicant or entity seeking BRD 
certification.
    An applicant requesting a certification phase LOA to test an 
unapproved hard or soft TED as a BRD must first apply for and obtain 
from the RA an experimental TED authorization pursuant to 
requirements of 50 CFR part 223.207(e). The application for the 
certification phase LOA also must append a copy of that 
authorization.

A.1 Special Circumstances Not Covered by Protocol

    Because actual testing conditions may vary, it may be necessary 
to deviate from the prescribed protocol to determine if a BRD 
candidate meets the bycatch reduction criterion. Any foreseeable 
deviations from the protocol must be described and justified in the 
application, and if scientifically acceptable will be approved by 
the RA in the LOA. The RA may consult with evaluation personnel to 
determine whether the deviations are scientifically acceptable. 
Without the RA's approval in the LOA, results from any tests 
deviating from the protocol may be rejected as scientifically 
unacceptable, and could result in a denial of certification.

B. Observer Requirement

    A qualified observer must be on board the vessel during all 
certification testing operations (See Appendix I). A list of 
qualified observers is available from the RA. Observers may include 
employees or individuals acting on behalf of NMFS, state fishery 
management agencies, universities, or private industry who meet the 
minimum requirements outlined in Appendix I, but the individual 
chosen may not have a current or prior financial relationship with 
the entity seeking BRD certification. It is the responsibility of 
the applicant to ensure that a qualified observer is on board the 
vessel during the certification tests. Compensation to the observer, 
if necessary, must be paid by the applicant. Any change in 
information or testing circumstances, such as replacement of the 
observer, must be reported to the RA within 30 days. Under 50 CFR 
600.746, the owner and operator of any fishing vessel required to 
carry an observer as part of a mandatory observer program under the 
Magnuson-Stevens Fishery Conservation and Management Act (16 U.S.C. 
1801, et seq.) is required to comply with guidelines, regulations, 
and conditions to ensure their vessel is adequate and safe to carry 
an observer, and to allow normal observer functions to collect 
scientific information as described in this protocol. A vessel owner 
is deemed to meet this requirement if the vessel displays one of the 
following: (i) A current Commercial Fishing Vessel Safety 
Examination decal, issued within the last 2 years, that certifies 
compliance with regulations found in 33 CFR, chapter I, and 46 CFR, 
chapter I; (ii) a certificate of compliance issued pursuant to 46 
CFR 28.710; or (iii) a valid certificate of inspection pursuant to 
46 U.S.C. 3311.

C. Issuance

    The RA will review the application for completeness. If the 
application is not complete, the RA will notify the applicant of the 
incompleteness and give the applicant an opportunity to cure. If the 
incompleteness is not cured within 30 days, the RA will return the 
application to the applicant. Upon receipt of a complete 
application, the RA will issue a LOA to conduct certification phase 
testing of the BRD candidate specified in the application if: (1) 
The test plan meets the requirements of the protocol; (2) the 
qualified observer named in the application has no current or prior 
financial relationship with the entity seeking BRD certification; 
(3) the BRD candidate design is substantially unlike BRD designs 
previously determined not to meet the current bycatch reduction 
criterion, or if the BRD candidate design is substantially similar 
to a BRD design previously determined not to meet the current 
bycatch reduction criterion, the application demonstrates that the 
design could meet the bycatch reduction criterion upon retesting 
(e.g., the application shows that statistical results could be 
improved upon retesting by such things as a larger sample size than 
that previously used); and (4) the results of any pre-certification 
phase testing conducted indicate a reasonable scientific basis for 
further testing. The submission of pre-certification phase data to 
provide a scientific basis for the conduct of certification testing 
is not an absolute requirement for the issuance of a certification 
phase LOA. For example, a request to conduct certification phase 
testing of a minor modification of a certified BRD design would not 
need to include pre-certification phase data. Similarly, a request 
for certification phase testing of a previously failed design that 
under a different test plan (e.g., larger sample sizes) could yield 
improved statistical results would likewise not need pre-
certification phase data. However, pre-

[[Page 56257]]

certification phase data would normally be needed to establish a 
reasonable scientific basis for conducting certification phase 
testing (e.g., that the BRD could meet the certification criterion 
upon certification testing). In making these determinations, the RA 
may consult with evaluation and oversight personnel. If a LOA to 
conduct certification phase testing is denied, the RA will provide a 
letter of explanation to the applicant, together with relevant 
recommendations to address the deficiencies resulting in the denial. 
Issuance of a LOA allows the applicant to remove or disable the 
existing certified BRD in one net (to create a control net) and to 
place the BRD candidate in another net in lieu of a certified BRD 
(to create an experimental net). All other trawls under tow during 
the tests must be equipped with a BRD. All trawls under tow during 
the certification tests must be equipped with an approved TED unless 
operating under an authorization issued pursuant to 50 CFR 
223.207(e). The LOA will specify the date when the applicant may 
begin to test the BRD candidate, the observer who will conduct the 
onboard data collection, and the vessel to be used during the test. 
The LOA and experimental TED authorization, if applicable, must be 
onboard the vessel while the certification phase tests are being 
conducted.

D. Testing Protocol

    Certification testing must be conducted in areas and at times 
when commercial quantities of penaeid shrimp and finfish pertinent 
to the certification testing are available to the gear.
    Certification testing of BRDs for use in the Gulf EEZ west of 
85[deg]30' W. long., must be conducted in areas and at times when 
juvenile (age 0 and age 1) red snapper are available to the gear. 
The best time for testing such a BRD candidate is July and August 
(July 1-August 31) due to the availability of red snapper on the 
penaeid shrimp commercial grounds located shoreward of the 100-fm 
(183-m) depth contour west of 85[deg]30' W. long., the approximate 
longitude of Cape San Blas, FL. A certification test conducted for 
BRD use west of 85[deg]30' W. long. may also be evaluated for BRD 
use east of 85[deg]30' W. long. because the requirement that 
``finfish'' were available to the gear would have been satisfied. 
However, it is preferable that certification testing for BRD use 
east of 85[deg]30' W. long. be conducted in that same area.
    Data for all certification testing should be recorded on the 
forms found in Appendices B through G, using the instructions 
provided for each form.

D.1. Tuning the Control and Experimental Trawls Prior to BRD 
Certification Trials

    The primary assumption in assessing the bycatch reduction 
efficiency of the BRD candidate during paired-net tests is that the 
inclusion of the BRD candidate in the experimental net is the only 
factor causing a difference in catch from that of the control net. 
Therefore, it is imperative that the fishing efficiency of the two 
nets be as similar as possible prior to starting the certification 
tests. Catch data from no more than 20 tuning tows should be 
collected on nets that will be used as control and experimental 
trawls to determine if there is a between-net or between-side (port 
vs. starboard) difference in fishing efficiency (bias). Any net/side 
bias will be reflected as differing catch rates of shrimp and total 
finfish between two nets that were towed simultaneously. During the 
tuning tows, these nets should be equipped with identical approved 
hard TEDs, without the BRD candidate being installed. Using this 
information, the applicant should identify and minimize the causes 
for any net/side bias, to the extent practicable, by making 
appropriate trawl gear adjustments. Form D-1 from Appendix D should 
be used to record the net/side bias data collected from these tows. 
These data will enable the RA to determine if any net/side bias 
existed in either trawl in assessing the BRD candidate's 
performance.
    If the applicant is testing a soft TED as a BRD, it will be 
imperative that little or no position or side bias with the trawl 
nets be demonstrated before the certification trials are initiated. 
Once any net/side bias is corrected using identical approved hard 
TEDs in both nets, any alterations in catch rate following the 
substitution of the soft TED into the experimental net can then be 
attributed to that TED's influence.

D.2. Retention of Data Collected During Tuning Trials

    All data collected during tuning trials and used for minimizing 
the net/side bias must be documented and submitted to the RA along 
with the testing data for evaluation. Additional information on 
tuning shrimp trawls is available from the Harvesting Technology 
Branch, Mississippi Laboratories, Pascagoula Facility, 3209 Frederic 
Street, Pascagoula, Mississippi 39568-1207; phone (601) 762-4591.

D.3. Certification Tests

    The certification tests must follow the testing protocol where 
paired identical trawls are towed by a trawler in acceptable testing 
areas (see introductory paragraph of section D). For tests of BRD 
candidates that do not encompass testing a hard or soft TED as the 
BRD candidate, identical approved hard TEDs are required in each 
trawl and one of the trawls must be equipped with a functioning BRD 
candidate. To test a hard or soft TED as a BRD candidate, the 
control net must be equipped with an approved hard TED, and the 
experimental net must be equipped with the TED that is acting as the 
BRD candidate.
    A minimum sample size of 30 successful tows per test is 
required. Additional tows may be necessary for sufficient 
statistical evidence, especially if catch of the species upon which 
the bycatch reduction criterion is based (e.g., red snapper) is 
highly variable. A gear change (i.e., changing nets, doors, or 
rigging) during a test constitutes the beginning of a new test. All 
certification tows must be no less than 2 hours and no more than 8 
hours in duration. The applicant may select any tow time within this 
range. Once a tow time is selected, no tow time during a series of 
tests may vary by more than 10 percent.
    To avoid potential biases associated with trynet catches, the 
outside trawls on quad-rigged vessels must be used as the control 
and experimental trawls, and for double-rigged vessels, the use of a 
trynet is prohibited.
    The functioning BRD candidate must be switched every 4-6 tows 
(approximately every 2 days) between the two trawl nets. This 
process must be repeated, ensuring that an equal number of 
successful tows are made with the BRD candidate employed in both the 
port and starboard nets, until a minimum of 30 successful tows have 
been completed. For BRDs incorporated in the codend of the net, this 
process can be facilitated by the use of zippers, or other quick-
connection devices, to more easily move the codends between nets; 
however, simply switching the entire net will not satisfy this 
requirement because doing so would not resolve net bias. Such quick-
connection devices must be attached behind the TED. The TED must not 
be moved unless the BRD is actually incorporated into the TED 
portion of the net. Where a hard TED is being tested as a BRD 
candidate, that portion of the net including the TEDs must be moved, 
and again, quick-connection devices located in front of the TEDs may 
be used.
    A different procedure must be followed to conduct tests of an 
approved or experimental soft TED as a BRD candidate. To conduct 
these tests, the applicant must first demonstrate that little or no 
side/net bias exists between the two nets to be used in the test 
(see D.1.). Removing the soft TED from one trawl net and installing 
it in the other net is not required. For these tests, the control 
(with a hard TED) and experimental (with the soft TED) nets must be 
disconnected from the doors and their positions switched from one 
side of the vessel to the other. The first switch must be made after 
successfully completing approximately 25 percent of the total number 
of intended tows. This process must be repeated, at 25 percent 
intervals, until at least 30 successful tows are completed (i.e., 
every 7-8 successful tows).
    Following each paired tow, the catches from the control and 
experimental nets must be examined separately. This requires that 
the catch from each net be kept separate from each other, as well as 
from the catch taken in other nets fished during that tow. First, 
the observer must weigh the total catch of each test net (control 
and experimental nets). If the catch in a net does not fill one 
standard 1-bushel (ca. 10 gallon) (30 liters) polyethylene shrimp 
basket (ca. 70 pounds) (31.8 kg), but the tow is otherwise 
considered successful, data must be collected on the entire catch of 
that net, and recorded as a ``select'' sample (see Appendix E). If 
the catch in a net exceeds 70 pounds (31.8 kg), a well-mixed sample 
consisting of one standard 1-bushel (ca. 10 gallon) (30 liters) 
polyethylene shrimp basket must be taken from the total catch of 
that net.
    Data must be collected on Form E-1 for the following species or 
general groups found in each of the samples: (1) Penaeid shrimp--
brown, white and pink shrimp from each sample must be separated by 
species, counted and weighed; in addition, the weight for those 
penaeid shrimp species caught in each test net, but that were not 
included in the sample, must be recorded so that a total

[[Page 56258]]

shrimp catch for each net (by weight) is documented; (2) crustacea--
mantis shrimp, sugar shrimp, seabobs, crabs, lobsters and other 
similar species--must be weighed as an aggregate; (3) other 
invertebrates--squid, jellyfish, starfish, sea pansies, shells, and 
other similar species--must be weighed as an aggregate; (4) each 
finfish species or species group listed in Appendix E must be 
weighed and counted; (5) other finfish--including all other fish not 
listed on the above-referenced form must be weighed as an aggregate; 
and (6) debris (mud, rocks, and related matter) must be weighed as 
an aggregate.
    ``Select'' finfish species (page E-3 of this Manual) (i.e., 
particular species to be quantified from the total catch and not 
just the sample) are red snapper, Spanish mackerel, and king 
mackerel. All individuals of the ``Select'' species from each test 
net (control and experimental net) must be collected, counted, 
weighed, and recorded. Lengths for as many as 30 individuals of each 
select species must be recorded on Form F-1. These data are 
necessary to robustly determine age-class composition, and specific 
mortality reductions attributable to each of the age classes.
    Applicants must also collect qualitative information, using Form 
G-1, on the condition (alive or dead) and fate (floated off, swam 
down, eaten) of the discards whenever possible, and note the 
presence of any predator species such as sharks, porpoises, and 
jacks that are observed. The condition and fate of the bycatch is 
important for determining the fishing mortality and waste associated 
with this discard.

E. Reports

    A report on the BRD candidate test results must be submitted for 
certification. The report must contain a comprehensive description 
of the tests, copies of all completed data forms used during the 
certification trials, and photographs, drawings, and similar 
material describing the BRD. The captain or owner must sign and 
submit the cover form (Appendix A). The report must include a 
description and explanation of any unforseen deviations from the 
protocol which occurred during the test. Applicants must provide 
information on the cost of materials, labor, and installation of the 
BRD candidate. In addition, any unique or special circumstances of 
the tests, including special operational characteristics or fishing 
techniques which enhance the BRD's performance, should be described 
and documented as appropriate.

F. Certification

    The RA will determine whether the required reports and 
supporting materials are sufficient to evaluate the BRD candidate's 
efficiency. The RA also will determine whether the applicant adhered 
to the prescribed testing protocol, and whether the BRD candidate 
meets the bycatch reduction criterion. In making a decision, the RA 
may consult with evaluation and oversight personnel.
    The RA will determine the effectiveness of the BRD candidate. 
For the western Gulf, the statistical protocol in Appendix H 
provides the methodology that the RA will use to estimate the 
reduction in bycatch mortality on age-1 juvenile red snapper if the 
test is conducted during the primary period (July or August). Tests 
conducted during other parts of the year will, most likely, catch 
both age 0 and age 1 red snapper. To evaluate the overall reduction 
in mortality rate of these juvenile age classes attributable to the 
BRD candidate will require alternative extensive analysis, involving 
use of the Goodyear (1995) stock assessment model to assign 
mortality reductions by specific size classes within the age 0 and 
age 1 red snapper catch.
    For the eastern Gulf the RA will determine the effectiveness of 
the BRD candidate to, on average, reduce the bycatch of finfish by 
30 percent by weight compared to the bycatch of finfish in the 
designated control net. To evaluate the efficiency of the BRD 
candidate, the RA will rely on the Southeast Fisheries Science 
Center to provide statistically valid mean reduction rates in 
finfish bycatch attributable to the BRD candidate.
    Following a favorable determination of these criteria, the RA 
will certify the BRD (with any appropriate conditions as indicated 
by test results) and publish the certification in the Federal 
Register.

IV. BRDs Not Certified and Resubmission Procedures

    The RA will advise the applicant, in writing, if a BRD is not 
certified. This notification will explain why the BRD was not 
certified and what the applicant may do to either modify the BRD or 
the testing procedures to improve the chances of having the BRD 
certified in the future. If certification was denied because of 
insufficient information, the RA will explain what information is 
lacking. The applicant must provide the additional information 
within 60 days from receipt of such notification; thereafter, the 
applicant must re-apply. If the RA subsequently certifies the BRD, 
the RA will announce the certification in the Federal Register.

V. Decertification of BRDs

    The RA will decertify a BRD whenever it is determined that it no 
longer satisfies the bycatch reduction criterion. Before determining 
whether to decertify a BRD, the Council and public will be advised 
and provided an opportunity to comment on the advisability of any 
proposed decertification. The RA will consider any comments from the 
Council and public, and if the RA elects to proceed with 
decertification of the BRD, the RA will publish proposed and final 
rules in the Federal Register with a comment period of not less than 
15 days on the proposed rule.

VI. Interactions With Sea Turtles

    The following section is provided for informational purposes. 
Sea turtles are listed under the Endangered Species Act as either 
endangered or threatened. The following procedures apply to 
incidental take of sea turtles under 50 CFR 223.206(d)(1):
    Any sea turtles taken incidentally during the course of fishing 
or scientific research activities must be handled with due care to 
prevent injury to live specimens, observed for activity, and 
returned to the water according to the following procedures:
    (A) Sea turtles that are actively moving or determined to be 
dead (as described in paragraph (B)(4) below) must be released over 
the stern of the boat. In addition, they must be released only when 
fishing or scientific collection gear is not in use, when the engine 
gears are in neutral position, and in areas where they are unlikely 
to be recaptured or injured by vessels.
    (B) Resuscitation must be attempted on sea turtles that are 
comatose or inactive by:
    (1) Placing the turtle on its bottom shell (plastron) so that 
the turtle is right side up and elevating its hindquarters at least 
6 inches (15.2 cm) for a period of 4 to 24 hours. The amount of 
elevation depends on the size of the turtle; greater elevations are 
needed for larger turtles. Periodically, rock the turtle gently left 
to right and right to left by holding the outer edge of the shell 
(carapace) and lifting one side about 3 inches (7.6 cm) then 
alternate to the other side. Gently touch the eye and pinch the tail 
(reflex test) periodically to see if there is a response.
    (2) Sea turtles being resuscitated must be shaded and kept damp 
or moist but under no circumstance be placed into a container 
holding water. A water-soaked towel placed over the head, carapace, 
and flippers is the most effective method in keeping a turtle moist.
    (3) Sea turtles that revive and become active must be released 
over the stern of the boat only when fishing or scientific 
collection gear is not in use, when the engine gears are in neutral 
position, and in areas where they are unlikely to be recaptured or 
injured by vessels. Sea turtles that fail to respond to the reflex 
test or fail to move within 4 hours (up to 24, if possible) must be 
returned to the water in the same manner as that for actively moving 
turtles.
    (4) A turtle is determined to be dead if the muscles are stiff 
(rigor mortis) and/or the flesh has begun to rot; otherwise, the 
turtle is determined to be comatose or inactive and resuscitation 
attempts are necessary.
    Any sea turtle so taken must not be consumed, sold, landed, 
offloaded, transshipped, or kept below deck.

Appendix H--Statistical Procedures for Analyzing BRD Evaluation Data 
Relative to the Western Gulf Criterion

    NMFS will calculate the reduction in bycatch mortality (F) based 
on data gathered during the testing. Both age 0 and age 1 red 
snapper, ranging in length from 10 mm to 200 mm, occur frequently in 
shrimp trawls. During the July/August (July 1-August 31) period, the 
most recently spawned year class of fish have not fully recruited to 
the shrimp grounds; thus the catch is represented by a relatively 
narrow length range of individuals, all of which are considered to 
be age 1. The numerical reduction in catch-per-unit-effort (CPUE) of 
this specific age class is expected to be a good predictor of 
fishing mortality (F) reduction, although the size composition data 
will be checked for any particular test. The analysis of the data 
collected under this testing protocol will be based on a modified 
paired t-test. Because of the varying age and size composition of 
the red snapper catch taken at other times of the year, more 
detailed analyses through use of a stock assessment model (Goodyear 
1995) incorporating the size-specific reduction performance of the 
device and the seasonal progression of F must be conducted to 
determine if the BRD candidate will meet the bycatch reduction 
criterion. Based on the time of the year that the test is conducted, 
NMFS will utilize the appropriate technique to assess the 
performance of the BRD candidate as a service for the BRD sponsor.
    All experimental tows must be conducted in conformance with the 
requirements of the BRD testing protocol. Data collected from no 
more than 20 tuning tows of the control and experimental trawls 
(without the BRD candidate installed) must be included to determine 
if any net bias exists prior to beginning certification phase 
testing. To further reduce problems caused by no or low catches, a 
tow being considered for certification in the western Gulf must 
contain a minimum catch of 5 red snapper in at least one trawl for 
inclusion in the analysis. Once conducted, the tow and the 
corresponding collected data become the permanent part of the record 
and cannot be discarded. Only the successful tows will count toward 
the minimum required; however, information from other tows, if 
appropriate, will be used in the analysis.

Statistical Approach for Calculation of Bycatch Mortality (F) Reduction 
for Devices Tested in July/August

    The statistical approach assumes that the BRD to be tested does 
not achieve the minimum required reduction rate, (Ro). 
The hypotheses to be tested are as follows:

Ho: BRD does not achieve the minimum required reduction 
rate,
[GRAPHIC] [TIFF OMITTED] TP30SE03.036

Ha : BRD does achieve the minimum required reduction 
rate,
[GRAPHIC] [TIFF OMITTED] TP30SE03.037

R denotes the actual reduction rate (unknown), Ro denotes 
the minimum required reduction rate, [mu]c denotes the actual mean 
CPUE with the control, and [mu]b denotes the actual mean CPUE with 
the BRD.

    With any hypothesis testing, there are two risks involved known 
as type I error (rejection of true Ho) and type II error 
(acceptance of false Ho). The probabilities of committing 
these errors are denoted by alpha and beta, respectively. The 
probabilities are inversely related to each other. As alpha 
increases, beta decreases and vice versa. An alpha of 10 percent 
will be used. The two hypotheses are tested using a ``modified'' 
paired t-test.
    The CPUE values for the control and BRD trawls for each 
successful tow is computed first and is used in the following 
computations:

Where:
x the observed mean CPUE for the control,
y is the observed mean CPUE for the BRD,
sd0 is the standard deviation of di = {(1-
Ro)xi-Yi{time}  values,
n is the number of successful tows used in the analysis, and
i = 1,2, . . . ,n.

    The Ho will be rejected if t  
talpha,n-1 where 
talpha,n-1 denotes the (1--alpha)100th 
percentile score in the t distribution with (n-1) degrees of 
freedom.
    A (1-alpha) 100-percent two-sided confidence interval on R 
consists of all values of Ro for which Ho: R = 
Ro (versus Ha R [ne] Ro) cannot be 
rejected at the level of significance of alpha. One-sided confidence 
intervals on R could also be computed appropriately.

Appendix I--Qualifications of Observer

    An observer:
    1. Must have a Bachelor's degree in fisheries biology or closely 
related field from an accredited college, have at least 6 months 
experience working with a university, college, state fisheries 
agency, NMFS, or private research organization such as the Gulf and 
South Atlantic Fisheries Development Foundation as an observer on a 
trawler (including research trawlers) in the southeast region, or 
have successfully completed a training course conducted or approved 
by the Director of the NMFS Southeast Fisheries Science Center.
    2. Must not have a current or prior financial relationship with 
the entity seeking BRD certification. In addition, any individual:
    1. Applying to serve as an observer must provide the names, 
addresses, and telephone numbers of at least three references who 
can attest to the applicant's background, experiences, and 
professional ability. These references will be contacted; 
unsatisfactory references may be a basis for disapproval of an 
applicant as an observer.
    2. Wishing to serve as an observer should submit a resume and 
supporting documents to the Director, Southeast Fisheries Science 
Center, 75 Virginia Beach Drive, Miami, FL 33149. The Center will 
use this information to determine which names will to be included on 
a list of qualified observers. If an applicant is not approved as an 
observer, the RA will notify the applicant of the disapproval and 
will provide an explanation for the denial.
