SUPPLEMENTARY INFORMATION:
Background
On Jan 8, 2013 NMFS published a
Notice (78 FR 1201) that NMFS had
received an application for a permit for
scientific purposes and to enhance the
propagation and survival of a listed
species under the Endangered Species
Act of 1973. NMFS also announced the
availability for public review and
comment of a Draft Environmental
Assessment (EA) regarding issuance of
the permit, which involves take of coho
salmon listed as threatened under the
ESA. The dates that these documents
were to become available to the public
were incorrect, and this correction
clarifies when the documents will be
available for public viewing and

90-Day Finding on Two Petitions To
List White Marlin as Threatened or
Endangered Under the Endangered
Species Act

ACTION: Notice of 90-day petition
finding.
AGENCY:
We (NMFS) announce a 90day finding on two petitions to list
white marlin (Kajikia albidus) as
threatened or endangered under the
Endangered Species Act (ESA). We find
that the petitions do not present
substantial scientific information
indicating that the petitioned action
may be warranted.
ADDRESSES: Copies of the petitions and
related materials are available upon
request from the Assistant Regional
Administrator, Protected Resources

SUPPLEMENTARY INFORMATION:
Background
On February 9, 2012, we received a
petition from Mr. James Chambers to list
white marlin (Kajikia albidus) as
threatened or endangered under the
ESA. We received a separate petition to
list white marlin from the Center for
Biological Diversity (CBD) on April 3,
2012. Copies of these petitions are
available from us (see ADDRESSES,
above). The joint USFWS/NMFS
petition management handbook states
that if we receive two petitions for the
same species and a 90-day finding has
not yet been made on the earlier
petition, then the later petition will be
combined with the earlier petition and
a combined 90-day finding will be
prepared. Given that, this 90-day
finding addresses petitions from both
Mr. Chambers and CBD requesting us to
list white marlin under the ESA.

We have previously reviewed the
status of the white marlin for ESA
listing as a result of a petition and legal
action from these petitioners. In 2001,
we received our first petition from Mr.
Chambers, and the Biodiversity Legal
Foundation, requesting us to list the
white marlin as a threatened or
endangered species. We convened a
status review team to assess the species
status and the degree of threat and
prepared a status review report (Atlantic
White Marlin Status Review Document,
WMSRT, 2002). We published our
determination on September 9, 2002,
that white marlin did not warrant ESA
listing (67 FR 57204). In 2006, per a
settlement agreement between NMFS,
CBD, and the Turtle Island Restoration
Network, we revisited the status of the
white marlin following the 2006 stock
assessment by the International
Commission for the Conservation of
Atlantic Tunas (ICCAT). On December
21, 2006, we announced the initiation of
a white marlin status review and
solicited information regarding the
status of and threats to the species (71
FR 76639) and convened a new
biological review team (BRT) to
commence a status review. The report
(Atlantic White Marlin Status Review,
AWMSR, 2007) prepared by the BRT
was peer reviewed and the final
document incorporated peer review
comments. After considering the
AWMSR, we determined the white
marlin was neither threatened or
endangered (73 FR 843; January 4,
2008).
ESA Statutory and Regulatory
Provisions and Evaluation Framework
Section 4(b)(3)(A) of the ESA of 1973,
as amended (U.S.C. 1531 et seq.),
requires, to the maximum extent
practicable, that within 90 days of
receipt of a petition to list a species as
threatened or endangered, the Secretary
of Commerce make a finding on whether
that petition presents substantial
scientific or commercial information
indicating that the petitioned action
may be warranted, and to promptly
publish such finding in the Federal
Register (16 U.S.C. 1533(b)(3)(A)). When
we find that substantial scientific or
commercial information in a petition
indicates the petitioned action may be
warranted (a ‘‘positive 90-day finding’’),
we are required to promptly commence
a review of the status of the species
concerned during which we will
conduct a comprehensive review of the
best available scientific and commercial
information. In such cases, we are to
conclude the review with a finding as to
whether, in fact, the petitioned action is
warranted within 12 months of receipt

30JAN1
mstockstill on DSK4VPTVN1PROD with
6300
Federal Register / Vol. 78, No. 20 / Wednesday, January 30, 2013 / Notices
of the petition. Because the finding at
the 12-month stage is based on a more
thorough review of the available
information, as compared to the narrow
scope of review at the 90-day stage, a
‘‘may be warranted’’ finding does not
prejudge the outcome of the status
review.
Under the ESA, a listing
determination may address a ‘‘species,’’
which is defined to also include
subspecies and, for any vertebrate
species, any distinct population
segment (DPS) that interbreeds when
mature (16 U.S.C. 1532(16)). A joint
NOAA–U.S. Fish and Wildlife Service
(USFWS) policy clarifies the agencies’
interpretation of the phrase ‘‘distinct
population segment’’ for the purposes of
listing, delisting, and reclassifying a
species under the ESA (‘‘DPS Policy’’;
61 FR 4722; February 7, 1996). A
species, subspecies, or DPS is
‘‘endangered’’ if it is in danger of
extinction throughout all or a significant
portion of its range, and ‘‘threatened’’ if
it is likely to become endangered within
the foreseeable future throughout all or
a significant portion of its range (ESA
sections 3(6) and 3(20), respectively; 16
U.S.C. 1532(6) and (20)). Pursuant to the
ESA and our implementing regulations,
we determine whether species are
threatened or endangered because of
any one or a combination of the
following five section 4(a)(1) factors:
The present or threatened destruction,
modification, or curtailment of habitat
or range; overutilization for commercial,
recreational, scientific, or educational
purposes; disease or predation;
inadequacy of existing regulatory
mechanisms; and any other natural or
manmade factors affecting the species’
existence (16 U.S.C. 1533(a)(1), 50 CFR
424.11(c)).
ESA-implementing regulations issued
jointly by NMFS and USFWS (50 CFR
424.14(b)) define ‘‘substantial
information’’ in the context of reviewing
a petition to list, delist, or reclassify a
species as the amount of information
that would lead a reasonable person to
believe that the measure proposed in the
petition may be warranted. In evaluating
whether substantial information is
contained in a petition, the Secretary
must consider whether the petition: (1)
Clearly indicates the administrative
measure recommended and gives the
scientific and any common name of the
species involved; (2) contains detailed
narrative justification for the
recommended measure, describing,
based on available information, past and
present numbers and distribution of the
species involved and any threats faced
by the species; (3) provides information
regarding the status of the species over
VerDate Mar<15>2010

all or a significant portion of its range;
and (4) is accompanied by the
appropriate supporting documentation
in the form of bibliographic references,
reprints of pertinent publications,
copies of reports or letters from
authorities, and maps (50 CFR
424.14(b)(2)).
Court decisions clarify the
appropriate scope and limitations of the
Services’ review of petitions at the 90day finding stage, in making a
determination whether a petitioned
action ‘‘may be’’ warranted. As a general
matter, these decisions hold that a
petition need not establish a ‘‘strong
likelihood’’ or a ‘‘high probability’’ that
a species is either threatened or
endangered to support a positive 90-day
finding.
We evaluate the petitioner’s request
based upon the information in the
petition including its references, and the
information readily available in our
files. We do not conduct additional
research, and we do not solicit
information from parties outside the
agency to help us in evaluating the
petition. We will accept the petitioner’s
sources and characterizations of the
information presented, if they appear to
be based on accepted scientific
principles, unless we have specific
information in our files that indicates
the petition’s information is incorrect,
unreliable, obsolete, or otherwise
irrelevant to the requested action.
Information that is susceptible to more
than one interpretation or that is
contradicted by other available
information will not be dismissed at the
90-day finding stage, so long as it is
reliable and a reasonable person would
conclude it supports the petitioner’s
assertions. In other words, conclusive
information indicating the species may
meet the ESA’s requirements for listing
is not required to make a positive 90day finding. We will not conclude that
a lack of specific information alone
negates a positive 90-day finding, if a
reasonable person would conclude that
the unknown information itself suggests
an extinction risk of concern for the
species at issue.
To make a 90-day finding on a
petition to list a species, we evaluate
whether the petition presents
substantial scientific or commercial
information indicating the subject
species may be either threatened or
endangered, as defined by the ESA.
First, we evaluate whether the
information presented in the petition,
along with the information readily
available in our files, indicates that the
petitioned entity constitutes a ‘‘species’’
eligible for listing under the ESA. Next,
we evaluate whether the information
PO 00000
Frm 00012
Fmt 4703
Sfmt 4703
indicates that the species at issue faces
extinction risk that is cause for concern;
this may be indicated in information
expressly discussing the species’ status
and trends, or in information describing
impacts and threats to the species. We
evaluate any information on specific
demographic factors pertinent to
evaluating extinction risk for the species
at issue (e.g., population abundance and
trends, productivity, spatial structure,
age structure, sex ratio, diversity,
current and historical range, habitat
integrity or fragmentation), and the
potential contribution of identified
demographic risks to extinction risk for
the species. We then evaluate the
potential links between these
demographic risks and the causative
impacts and threats identified in section
4(a)(1).
Information presented on impacts or
threats should be specific to the species
and should reasonably suggest that one
or more of these factors may be
operative threats that act or have acted
on the species to the point that it may
warrant protection under the ESA.
Broad statements about generalized
threats to the species, or identification
of factors that could negatively impact
a species, do not constitute substantial
information that listing may be
warranted. We look for information
indicating that not only is the particular
species exposed to a factor, but that the
species may be responding in a negative
fashion; then we assess the potential
significance of that negative response.
Many petitions identify risk
classifications made by other
organizations or agencies, such as the
International Union on the Conservation
of Nature (IUCN), the American
Fisheries Society (AFS), or NatureServe,
as evidence of extinction risk for a
species. Risk classifications by other
organizations or made under other
Federal or state statutes may be
informative, but the classification alone
may not provide the rationale for a
positive 90-day finding under the ESA.
For example, as explained by
NatureServe, their assessments of a
species’ conservation status do ‘‘not
constitute a recommendation by
NatureServe for listing under the U.S.
Endangered Species Act’’ because
NatureServe assessments ‘‘have
different criteria, evidence
requirements, purposes and taxonomic
coverage than government lists of
endangered and threatened species, and
therefore these two types of lists should
not be expected to coincide’’ (https://
www.natureserve.org/prodServices/
statusAssessment.jsp). Thus, when a
petition cites such classifications, we
will evaluate the source information

that the classification is based upon, in
light of the standards on extinction risk
and impacts or threats discussed above.
Species Description
The white marlin is a billfish (Family
Istiophoridae) that inhabits the tropical
and temperate waters of the Atlantic
Ocean and adjacent seas. White marlin
is considered to be a panmictic species:
individuals move about freely within
the Atlantic Ocean, over thousands of
miles, and breed freely with other
members of the population. Molecular
markers have demonstrated that white
marlin move significantly among
regions (Graves and McDowell, 2003;
Wells et al., 2010). White marlin exhibit
sexually dimorphic growth patterns
with females growing faster and
achieving larger sizes than males. There
is little information regarding the age
and growth of white marlin as billfish
are extremely difficult to age. Data
limited to a single location found that
the sex ratio (proportion of females to
males) increased steadily with size and
nearly all fish larger than 2,000 cm were
female (Arocha and Barrios, 2009).
White marlin are primarily general
piscivores, but also feed on squid and
other prey items (Nakamura, 1985).
Spawning activity occurs during the
spring (March through June) in
northwestern Atlantic tropical and subtropical waters marked by relatively
high surface temperatures (20°–29°C)
and salinities (>35 ppt). The presence of
white marlin larvae suggests there are at
least five spawning areas in the western
north Atlantic Ocean: Northeast of Little
Bahama Bank off the Abaco Islands;
northwest of Grand Bahama Island;
southwest of Bermuda; the Mona
Passage, east of the Dominican
Republic; and the Gulf of Mexico
(AWMSR, 2007).
White marlin, along with other
billfish and tunas, are managed
internationally by the member nations
of the ICCAT. ICCAT, through the
Standing Committee for Research and
Statistics (SCRS), conducts regular stock
assessments for species under its
purview: white marlin stock
assessments were conducted in 2002,
2006, and 2012. Both white marlin and
roundscale spearfish (Tetrapturus
georgii) are taken as bycatch on longline
fishing gear targeting tuna and
swordfish (AWMSR, 2007). White
marlin are also targeted in recreational
fishing tournaments along the U.S. east
coast, which also often land roundscale
spearfish (AWMSR, 2007).
White marlin and the roundscale
spearfish are sympatric and
morphologically very similar.
Roundscale spearfish were validated as
VerDate Mar<15>2010
20:43 Jan 29, 2013
Jkt 229001
a genetically distinct species in 2006
(Shivji et al., 2006). Species
misidentification of the roundscale
spearfish and the white marlin has
likely occurred given the complexity of
accurate identification (AWMSR, 2007).
Little is known about the life history of
roundscale spearfish. Beerkricher et al.
(2009) examined the proportion of
spearfish in the total catch identified as
white marlin and found it ranged
between 0 and 100 percent (n=1443,
mean = 27 percent) per set observed in
the western north Atlantic, with high
variability across geographic areas.
Roundscale spearfish were found more
frequently offshore compared to
nearshore. Given the misidentification
problems between white marlin and
roundscale spearfish, the SCRS working
group decided prior to the 2012 stock
assessment that white marlin and
roundscale spearfish would be
combined as a mixed stock until more
accurate species identification and
differentiation of species catches are
available (SCRS, 2011).
Total catch of white marlin peaked in
the mid 1960’s (AWMSR, 2007). Total
catch of white marlin remained
relatively stable through the 1980s and
into the early 1990s. In the mid 1990s
there was a marked decline in white
marlin catch. ICCAT responded by
adopting numerous resolutions
protective of white marlin, including a
reduction in landings and a rebuilding
program (AWMSR, 2002; WMSRT,
2007). Both the 2002 and the 2007 white
marlin status reviews discussed this
marked decline in total catch and
described protective measures adopted
by ICCAT (WMSRT, 2002; AWMSR,
2007). White marlin catch has remained
relatively stable in recent years (SCRS,
2011; 2012). Relative fishing mortality
has been declining over the past ten
years, it is now most likely to be below
the fishing mortality rate expected to
yield maximum sustainable yield
(Fmsy), and it is highly likely to remain
below Fmsy (SCRS, 2012). The BRT
concluded that the current regulatory
mechanisms are sufficient to prevent
continued stock decline (AWMSR,
2007).
Analysis of the Petition
We evaluated whether the petitions
presented the information indicated in
50 CFR 424.14(b)(2). Both petitions
stated the administrative measures
recommended for the white marlin.
Neither petition included the scientific
name of the species. Both petitions
included a narrative justification for the
recommended measure, including some
information on numbers of the species,
historical geographic occurrences of the
PO 00000
Frm 00013
Fmt 4703
Sfmt 4703
6301
species, and threats faced by the
species. Both petitions utilize
information from the 2011 ICCAT Blue
Marlin Stock Assessment and While
Marlin Data Preparatory Meeting (SCRS,
2011). Only the CBD petition included
supporting references.
White marlin is recognized as a
taxonomically-distinct species and is
therefore an eligible entity for listing
under the ESA. We previously
determined the Atlantic white marlin
constitutes a single species throughout
the Atlantic Ocean and there are no
populations that warrant consideration
of ESA listing (73 FR 843; January 4,
2008). The Chambers petition, seeking
protection of the ‘‘North Atlantic subpopulation of the white marlin,’’
included information summarizing
spatial and temporal difference in
spawning north and south of the equator
that in turn indicates ‘‘two entirely
distinct sub-populations which do not
interbreed’’ and a graph showing total
catch of white marlin north of the
equator by gear with live and dead
discards from 1956–2010 (SCRS, 2011).
The Chambers petition did not include
any information supporting white
marlin population structure that was not
previously considered by us. Therefore
the best available information indicates
white marlin are a single species
throughout its range without separation
into populations.
Information on Impacts and Threats to
the Species
We evaluated whether the
information in the petitions and
information in our files concerning the
extent and severity of one or more of the
ESA section 4(a)(1) factors suggest these
impacts and threats may be posing a risk
of extinction for white marlin that is
cause for concern. Collectively, the
petitions state that three of the five
causal factors in section 4(a)(1) of the
ESA are adversely affecting the
continued existence of white marlin: (A)
Present or threatened destruction,
modification, or curtailment of its
habitat or range; (B) overutilization for
commercial and recreational purposes;
and (D) inadequacy of existing
regulatory mechanisms. In the following
sections, we use the information
presented in the petition and in our files
to determine whether the petitioned
action may be warranted.
Present and Threatened Destruction,
Modification, or Curtailment of Habitat
or Range
The CBD petition stated the range of
the white marlin has been reduced
between the 1960s and the 1990s per
Worm and Tittensor (2011). Other
E:\FR\FM\30JAN1.SGM
30JAN1
6302
Federal Register / Vol. 78, No. 20 / Wednesday, January 30, 2013 / Notices
information provided by CBD
contradicts this range reduction and
shows Worm and Tittensor’s (2011)
finding to be obsolete: Lynch et al.
(2011) includes a figure summarizing
distribution of white marlin in the
Atlantic Ocean from 2000 to 2006 that
indicates white marlin occur in all the
areas identified as absent by Worm and
Tittensor (2011). Information in our files
(SCRS, 2011; 2012) also indicates the
range has not contracted. Therefore we
conclude the petition does not provide
substantial information indicating the
range of the white marlin has been
constricted and further note that a slight
variation in range of a species that
occurs across the Atlantic Ocean and 70
degrees latitude would not alone
constitute an extinction risk.
The CBD petition states ‘‘studies have
found that billfish, such as white
marlin, are sensitive to water quality
conditions, which are rapidly changing
as a result of climate change and ocean
acidification’’ and refers to Lynch et al.
(2011). We reviewed Lynch et al. (2011)
and did not find statements supporting
CBDs’ assertions. Further, neither CBD
nor Lynch et al. (2011) provide any
explanation or connection of how water
quality condition, climate change, or
ocean acidification are operative threats
to the continued existence of the white
marlin. We did not find information in
our files indicating how presumed
changes in water quality from climate
change and ocean acidification would
be an extinction risk of concern to white
marlin.
In summary, information presented in
the two petitions and in our files does
not constitute substantial information
indicating that the present and
threatened destruction, modification, or
curtailment of habitat or range may be
causing extinction risk of concern for
white marlin.

Overutilization for Commercial and
Recreational Purposes
The CBD petition quotes from
Beerkircher et al. (2009) that white
marlin are among ‘‘the most
overexploited pelagic fishes.’’ The CBD
petition also attributes other statements
to ICCAT (SCRS, 2011) including
‘‘white marlin populations have failed
to rebuild, and they have also continued
to decline and landings indicate this
continued decline and the catch-perunit-effort shows instability in the
population.’’ We reviewed SCRS (2011)
and could not substantiate or find
support for the statements. In addition,
the CBD petition did not provide any
explanation on how these statements
correspond to extinction risk.
VerDate Mar<15>2010
20:43 Jan 29, 2013
Jkt 229001
The Chambers petition says the status
of the white marlin population ‘‘is well
below the level at which there is a
danger of recruitment failure which is
considered to begin at 50 percent of
MSY,’’ and, ‘‘Passing such a threshold
means there are becoming too few
breeders to replace the population
which can then spiral ever faster
towards extinction.’’ The Chambers
petition did not provide any supporting
information for these claims. It included
no information or explanation on how
this threshold corresponds to extinction
risk. The petition did not provide
information on recruitment failure or
the number of current breeders. We are
unaware of data, and did not find
information in our files, to support this
claim.
The CBD petition did provide some
information on white marlin population
size, somewhat relevant to Mr.
Chambers’ claims. It cites the decline in
B/Bmsy from 1.02 in 1970 to 0.44 in
2010 (Collette et al., 2011) as evidence
of overutilization of white marlin. B/
Bmsy is a relative abundance metric in
fishery management that expresses a
stock’s biomass as a proportion of the
biomass that would support the
continuous, maximum harvest of that
stock. Although it provides B/Bmsy
figures for white marlin, the CBD does
not provide any rationale why a B/Bmsy
of 0.44 causes an extinction risk of
concern. We do not believe 0.44 B/Bmsy
alone is a cause for concern, as it
represents fishing potential rather than
absolute abundance, and does not
necessarily have any relationship to a
species’ extinction risk. In addition, we
interpret the B/Bmsy trend presented in
Collette et al. (2011) as declining
between 1970 and 1990, followed by a
stable or increasing, but not decreasing,
stock size from 1990 through 2010.
The Chambers petition states white
marlin abundance has ‘‘fallen to about
2 percent of an unfished level of
abundance by the end of 2007.’’ While
population decline can result in
extinction risk that is cause for concern
in certain circumstances, the decline
described in the Chambers petition
appears to have been derived from
reported landings. Although a decline in
reported landings can oftentimes
indicate a decrease in total abundance,
in this case it is likely this decline in
landings is a result of the regulations
ICCAT has instituted since 1995 to
reduce white marlin landings.
Therefore, we conclude landings data
do not indicate a decline in white
marlin abundance and do not indicate
that white marlin is being negatively
impacted by overutilization. We are
unaware of any data suggesting that
PO 00000
Frm 00014
Fmt 4703
Sfmt 4703
white marlin have declined to the level
Mr. Chambers claims, which would
correspond to a B/Bmsy value of 0.04 or
one eleventh the value presented in the
CBD petition.
The CBD petition cites the
‘‘vulnerable’’ status classification made
by IUCN to support listing white marlin
as threatened or endangered under the
ESA, and includes Collette et al. (2011)
as a reference. As discussed above, risk
classifications by other organizations or
agencies (e.g., IUCN) do not alone
provide rationale for a positive 90-day
finding under the ESA. However we
have evaluated the IUCN source
information for white marlin relative to
the ESA standards of extinction risk and
we find the IUCN classification does not
present information that was not already
considered in the 2007 status review
(e.g., the 2006 ICCAT stock assessment)
or that was not included by CBD in their
petition and discussed herein (e.g.,
range constriction as described by
Worm and Tittensor, 2011 and catch
composition per Beerkircher et al.,
2009).
The CBD petition discusses how
roundscale spearfish reported in the
white marlin catch can affect ICCAT
stock assessments and requests a new
assessment. Citing Beerkircher et al.
(2009), the CBD petition suggests we
adopt a proportion of roundscale
spearfish to white marlin in the total
catch between 21 and 42 percent and reevaluate our prior finding. As
previously discussed, the proportion of
spearfish in the total catch identified as
white marlin was highly variable and
spatially limited (Beerkircher et al.,
2009). In evaluating the findings from
Beerkircher et al. (2009), ICCAT
subsequently concluded reliable
estimates on the proportion of
roundscale spearfish reported as white
marlin in the catch rates were not
available, and elected to perform a
mixed stock assessment until more
accurate species identification and
differentiation of species catch were
available (SCRS, 2011). Specifically,
ICCAT determined a comprehensive
Atlantic-wide sampling program, as
well as a large-scale retrospective
analysis, would be required for a
reliable population-level estimate of
roundscale spearfish reported as white
marlin (SCRS, 2011). All white marlin
biological material sampled prior to
2006 is currently presumed to contain
unknown proportions of roundscale
spearfish (SCRS, 2012). We
acknowledge it is important to consider
the ratio of roundscale spearfish
reported in the white marlin catch,
however we concur with ICCAT that it
is not possible at this time.

The CBD petition referenced the
simulations performed by Beerkircher et
al. (2009) and stated they were an
indication of population decline. The
CBD petition does not include any
additional information indicating how
these simulations indicate extinction
risk. We carefully reviewed the
simulations; we noted they include the
period 1955 through 1999 when the
marked decline in white marlin catch
occurred, and do not project through
subsequent years when bycatch was
stabilized and reduced. Therefore we do
not find this simulated decline in
roundscale spearfish concurrent with
white marlin surprising, as the
simulations are partitioning the noted
decline in one species’ (white marlin)
catch rates that occurred through the
1990s across two species (white marlin
and roundscale spearfish). We conclude
the simulations do not provide relevant
information regarding the extinction
risk of white marlin or information on
the current status of the white marlin.
In summary, the petitions do not
present information regarding the
decline of white marlin catches in the
1990s that we have not already
considered in prior determinations as
discussed (see ‘‘Species Description’’).
There is no information in our files to
suggest our prior conclusions regarding
the 1990s decline in white marlin catch
were incorrect or insufficient. We
conclude the characterization of
continuing population decline in the
petitions is unsubstantiated. The
petitions did not provide substantial
information that white marlin
populations are unstable or that species
misclassification poses an extinction
risk. Therefore we conclude the
petitions do not present substantial
scientific information indicating that
listing may be warranted due to
overutilization for commercial and
recreational purposes.
Inadequacy of Existing Regulatory
Mechanisms
The CBD petition states Lynch et al.
(2011) ‘‘demonstrates that existing
regulatory mechanisms are inadequate
to prevent the decline of white marlin.’’
We carefully reviewed Lynch et al.
(2011) and could not find statements
supporting CBDs’ assertions. In fact,
Lynch et al. (2011) states measures
already implemented are likely
beneficial to some degree; in
combination, reductions in landing and
live release ‘‘should slow and possibly
reverse downward population trends
* * * some evidence of population
response to these management strategies
may already be observable.’’ The
Chambers petition states that ICCAT is

not managing the white marlin to
produce the maximum sustainable
yield, but does not explain how this
leads to extinction risk of concern.
Fishery management targets, such as
maximum sustainable yield, and
statuses, are based on different criteria
than that required by the ESA and, thus,
do not necessarily have any relationship
to a species’ extinction risk. There is no
information in our files that indicates
the current regulatory mechanisms are
insufficient to prevent endangerment of
the white marlin. The petitions did not
present other information to indicate
how the inadequacy of existing
regulatory mechanisms is an extinction
risk to the white marlin.
While the petitions state additional
regulations are required to ensure
rebuilding of the marlin populations,
they do not provide any explanation on
how the existing regulatory mechanisms
are inadequate to prevent endangerment
of the white marlin. In summary we find
the petitions, and information readily
available in our files, do not present
substantial information to suggest the
existing regulatory mechanisms are
inadequate and may be causing an
extinction risk for white marlin.
After reviewing the information
contained in the petitions, as well as
information readily available in our
files, we conclude these petitions do not
present substantial scientific or
commercial information indicating the
petitioned action may be warranted.

SUPPLEMENTARY INFORMATION:
Background
On February 9, 2012, we received a petition from Mr. James Chambers
to list white marlin (Kajikia albidus) as threatened or endangered
under the ESA. We received a separate petition to list white marlin
from the Center for Biological Diversity (CBD) on April 3, 2012. Copies
of these petitions are available from us (see ADDRESSES, above). The
joint USFWS/NMFS petition management handbook states that if we receive
two petitions for the same species and a 90-day finding has not yet
been made on the earlier petition, then the later petition will be
combined with the earlier petition and a combined 90-day finding will
be prepared. Given that, this 90-day finding addresses petitions from
both Mr. Chambers and CBD requesting us to list white marlin under the
ESA.
We have previously reviewed the status of the white marlin for ESA
listing as a result of a petition and legal action from these
petitioners. In 2001, we received our first petition from Mr. Chambers,
and the Biodiversity Legal Foundation, requesting us to list the white
marlin as a threatened or endangered species. We convened a status
review team to assess the species status and the degree of threat and
prepared a status review report (Atlantic White Marlin Status Review
Document, WMSRT, 2002). We published our determination on September 9,
2002, that white marlin did not warrant ESA listing (67 FR 57204). In
2006, per a settlement agreement between NMFS, CBD, and the Turtle
Island Restoration Network, we revisited the status of the white marlin
following the 2006 stock assessment by the International Commission for
the Conservation of Atlantic Tunas (ICCAT). On December 21, 2006, we
announced the initiation of a white marlin status review and solicited
information regarding the status of and threats to the species (71 FR
76639) and convened a new biological review team (BRT) to commence a
status review. The report (Atlantic White Marlin Status Review, AWMSR,
2007) prepared by the BRT was peer reviewed and the final document
incorporated peer review comments. After considering the AWMSR, we
determined the white marlin was neither threatened or endangered (73 FR
843; January 4, 2008).
ESA Statutory and Regulatory Provisions and Evaluation Framework
Section 4(b)(3)(A) of the ESA of 1973, as amended (U.S.C. 1531 et
seq.), requires, to the maximum extent practicable, that within 90 days
of receipt of a petition to list a species as threatened or endangered,
the Secretary of Commerce make a finding on whether that petition
presents substantial scientific or commercial information indicating
that the petitioned action may be warranted, and to promptly publish
such finding in the Federal Register (16 U.S.C. 1533(b)(3)(A)). When we
find that substantial scientific or commercial information in a
petition indicates the petitioned action may be warranted (a ``positive
90-day finding''), we are required to promptly commence a review of the
status of the species concerned during which we will conduct a
comprehensive review of the best available scientific and commercial
information. In such cases, we are to conclude the review with a
finding as to whether, in fact, the petitioned action is warranted
within 12 months of receipt
[[Page 6300]]
of the petition. Because the finding at the 12-month stage is based on
a more thorough review of the available information, as compared to the
narrow scope of review at the 90-day stage, a ``may be warranted''
finding does not prejudge the outcome of the status review.
Under the ESA, a listing determination may address a ``species,''
which is defined to also include subspecies and, for any vertebrate
species, any distinct population segment (DPS) that interbreeds when
mature (16 U.S.C. 1532(16)). A joint NOAA-U.S. Fish and Wildlife
Service (USFWS) policy clarifies the agencies' interpretation of the
phrase ``distinct population segment'' for the purposes of listing,
delisting, and reclassifying a species under the ESA (``DPS Policy'';
61 FR 4722; February 7, 1996). A species, subspecies, or DPS is
``endangered'' if it is in danger of extinction throughout all or a
significant portion of its range, and ``threatened'' if it is likely to
become endangered within the foreseeable future throughout all or a
significant portion of its range (ESA sections 3(6) and 3(20),
respectively; 16 U.S.C. 1532(6) and (20)). Pursuant to the ESA and our
implementing regulations, we determine whether species are threatened
or endangered because of any one or a combination of the following five
section 4(a)(1) factors: The present or threatened destruction,
modification, or curtailment of habitat or range; overutilization for
commercial, recreational, scientific, or educational purposes; disease
or predation; inadequacy of existing regulatory mechanisms; and any
other natural or manmade factors affecting the species' existence (16
U.S.C. 1533(a)(1), 50 CFR 424.11(c)).
ESA-implementing regulations issued jointly by NMFS and USFWS (50
CFR 424.14(b)) define ``substantial information'' in the context of
reviewing a petition to list, delist, or reclassify a species as the
amount of information that would lead a reasonable person to believe
that the measure proposed in the petition may be warranted. In
evaluating whether substantial information is contained in a petition,
the Secretary must consider whether the petition: (1) Clearly indicates
the administrative measure recommended and gives the scientific and any
common name of the species involved; (2) contains detailed narrative
justification for the recommended measure, describing, based on
available information, past and present numbers and distribution of the
species involved and any threats faced by the species; (3) provides
information regarding the status of the species over all or a
significant portion of its range; and (4) is accompanied by the
appropriate supporting documentation in the form of bibliographic
references, reprints of pertinent publications, copies of reports or
letters from authorities, and maps (50 CFR 424.14(b)(2)).
Court decisions clarify the appropriate scope and limitations of
the Services' review of petitions at the 90-day finding stage, in
making a determination whether a petitioned action ``may be''
warranted. As a general matter, these decisions hold that a petition
need not establish a ``strong likelihood'' or a ``high probability''
that a species is either threatened or endangered to support a positive
90-day finding.
We evaluate the petitioner's request based upon the information in
the petition including its references, and the information readily
available in our files. We do not conduct additional research, and we
do not solicit information from parties outside the agency to help us
in evaluating the petition. We will accept the petitioner's sources and
characterizations of the information presented, if they appear to be
based on accepted scientific principles, unless we have specific
information in our files that indicates the petition's information is
incorrect, unreliable, obsolete, or otherwise irrelevant to the
requested action. Information that is susceptible to more than one
interpretation or that is contradicted by other available information
will not be dismissed at the 90-day finding stage, so long as it is
reliable and a reasonable person would conclude it supports the
petitioner's assertions. In other words, conclusive information
indicating the species may meet the ESA's requirements for listing is
not required to make a positive 90-day finding. We will not conclude
that a lack of specific information alone negates a positive 90-day
finding, if a reasonable person would conclude that the unknown
information itself suggests an extinction risk of concern for the
species at issue.
To make a 90-day finding on a petition to list a species, we
evaluate whether the petition presents substantial scientific or
commercial information indicating the subject species may be either
threatened or endangered, as defined by the ESA. First, we evaluate
whether the information presented in the petition, along with the
information readily available in our files, indicates that the
petitioned entity constitutes a ``species'' eligible for listing under
the ESA. Next, we evaluate whether the information indicates that the
species at issue faces extinction risk that is cause for concern; this
may be indicated in information expressly discussing the species'
status and trends, or in information describing impacts and threats to
the species. We evaluate any information on specific demographic
factors pertinent to evaluating extinction risk for the species at
issue (e.g., population abundance and trends, productivity, spatial
structure, age structure, sex ratio, diversity, current and historical
range, habitat integrity or fragmentation), and the potential
contribution of identified demographic risks to extinction risk for the
species. We then evaluate the potential links between these demographic
risks and the causative impacts and threats identified in section
4(a)(1).
Information presented on impacts or threats should be specific to
the species and should reasonably suggest that one or more of these
factors may be operative threats that act or have acted on the species
to the point that it may warrant protection under the ESA. Broad
statements about generalized threats to the species, or identification
of factors that could negatively impact a species, do not constitute
substantial information that listing may be warranted. We look for
information indicating that not only is the particular species exposed
to a factor, but that the species may be responding in a negative
fashion; then we assess the potential significance of that negative
response.
Many petitions identify risk classifications made by other
organizations or agencies, such as the International Union on the
Conservation of Nature (IUCN), the American Fisheries Society (AFS), or
NatureServe, as evidence of extinction risk for a species. Risk
classifications by other organizations or made under other Federal or
state statutes may be informative, but the classification alone may not
provide the rationale for a positive 90-day finding under the ESA. For
example, as explained by NatureServe, their assessments of a species'
conservation status do ``not constitute a recommendation by NatureServe
for listing under the U.S. Endangered Species Act'' because NatureServe
assessments ``have different criteria, evidence requirements, purposes
and taxonomic coverage than government lists of endangered and
threatened species, and therefore these two types of lists should not
be expected to coincide'' (https://www.natureserve.org/prodServices/statusAssessment.jsp). Thus, when a petition cites such
classifications, we will evaluate the source information
[[Page 6301]]
that the classification is based upon, in light of the standards on
extinction risk and impacts or threats discussed above.
Species Description
The white marlin is a billfish (Family Istiophoridae) that inhabits
the tropical and temperate waters of the Atlantic Ocean and adjacent
seas. White marlin is considered to be a panmictic species: individuals
move about freely within the Atlantic Ocean, over thousands of miles,
and breed freely with other members of the population. Molecular
markers have demonstrated that white marlin move significantly among
regions (Graves and McDowell, 2003; Wells et al., 2010). White marlin
exhibit sexually dimorphic growth patterns with females growing faster
and achieving larger sizes than males. There is little information
regarding the age and growth of white marlin as billfish are extremely
difficult to age. Data limited to a single location found that the sex
ratio (proportion of females to males) increased steadily with size and
nearly all fish larger than 2,000 cm were female (Arocha and Barrios,
2009).
White marlin are primarily general piscivores, but also feed on
squid and other prey items (Nakamura, 1985). Spawning activity occurs
during the spring (March through June) in northwestern Atlantic
tropical and sub-tropical waters marked by relatively high surface
temperatures (20[deg]-29[deg]C) and salinities (>35 ppt). The presence
of white marlin larvae suggests there are at least five spawning areas
in the western north Atlantic Ocean: Northeast of Little Bahama Bank
off the Abaco Islands; northwest of Grand Bahama Island; southwest of
Bermuda; the Mona Passage, east of the Dominican Republic; and the Gulf
of Mexico (AWMSR, 2007).
White marlin, along with other billfish and tunas, are managed
internationally by the member nations of the ICCAT. ICCAT, through the
Standing Committee for Research and Statistics (SCRS), conducts regular
stock assessments for species under its purview: white marlin stock
assessments were conducted in 2002, 2006, and 2012. Both white marlin
and roundscale spearfish (Tetrapturus georgii) are taken as bycatch on
longline fishing gear targeting tuna and swordfish (AWMSR, 2007). White
marlin are also targeted in recreational fishing tournaments along the
U.S. east coast, which also often land roundscale spearfish (AWMSR,
2007).
White marlin and the roundscale spearfish are sympatric and
morphologically very similar. Roundscale spearfish were validated as a
genetically distinct species in 2006 (Shivji et al., 2006). Species
misidentification of the roundscale spearfish and the white marlin has
likely occurred given the complexity of accurate identification (AWMSR,
2007). Little is known about the life history of roundscale spearfish.
Beerkricher et al. (2009) examined the proportion of spearfish in the
total catch identified as white marlin and found it ranged between 0
and 100 percent (n=1443, mean = 27 percent) per set observed in the
western north Atlantic, with high variability across geographic areas.
Roundscale spearfish were found more frequently offshore compared to
nearshore. Given the misidentification problems between white marlin
and roundscale spearfish, the SCRS working group decided prior to the
2012 stock assessment that white marlin and roundscale spearfish would
be combined as a mixed stock until more accurate species identification
and differentiation of species catches are available (SCRS, 2011).
Total catch of white marlin peaked in the mid 1960's (AWMSR, 2007).
Total catch of white marlin remained relatively stable through the
1980s and into the early 1990s. In the mid 1990s there was a marked
decline in white marlin catch. ICCAT responded by adopting numerous
resolutions protective of white marlin, including a reduction in
landings and a rebuilding program (AWMSR, 2002; WMSRT, 2007). Both the
2002 and the 2007 white marlin status reviews discussed this marked
decline in total catch and described protective measures adopted by
ICCAT (WMSRT, 2002; AWMSR, 2007). White marlin catch has remained
relatively stable in recent years (SCRS, 2011; 2012). Relative fishing
mortality has been declining over the past ten years, it is now most
likely to be below the fishing mortality rate expected to yield maximum
sustainable yield (Fmsy), and it is highly likely to remain below Fmsy
(SCRS, 2012). The BRT concluded that the current regulatory mechanisms
are sufficient to prevent continued stock decline (AWMSR, 2007).
Analysis of the Petition
We evaluated whether the petitions presented the information
indicated in 50 CFR 424.14(b)(2). Both petitions stated the
administrative measures recommended for the white marlin. Neither
petition included the scientific name of the species. Both petitions
included a narrative justification for the recommended measure,
including some information on numbers of the species, historical
geographic occurrences of the species, and threats faced by the
species. Both petitions utilize information from the 2011 ICCAT Blue
Marlin Stock Assessment and While Marlin Data Preparatory Meeting
(SCRS, 2011). Only the CBD petition included supporting references.
White marlin is recognized as a taxonomically-distinct species and
is therefore an eligible entity for listing under the ESA. We
previously determined the Atlantic white marlin constitutes a single
species throughout the Atlantic Ocean and there are no populations that
warrant consideration of ESA listing (73 FR 843; January 4, 2008). The
Chambers petition, seeking protection of the ``North Atlantic sub-
population of the white marlin,'' included information summarizing
spatial and temporal difference in spawning north and south of the
equator that in turn indicates ``two entirely distinct sub-populations
which do not interbreed'' and a graph showing total catch of white
marlin north of the equator by gear with live and dead discards from
1956-2010 (SCRS, 2011). The Chambers petition did not include any
information supporting white marlin population structure that was not
previously considered by us. Therefore the best available information
indicates white marlin are a single species throughout its range
without separation into populations.
Information on Impacts and Threats to the Species
We evaluated whether the information in the petitions and
information in our files concerning the extent and severity of one or
more of the ESA section 4(a)(1) factors suggest these impacts and
threats may be posing a risk of extinction for white marlin that is
cause for concern. Collectively, the petitions state that three of the
five causal factors in section 4(a)(1) of the ESA are adversely
affecting the continued existence of white marlin: (A) Present or
threatened destruction, modification, or curtailment of its habitat or
range; (B) overutilization for commercial and recreational purposes;
and (D) inadequacy of existing regulatory mechanisms. In the following
sections, we use the information presented in the petition and in our
files to determine whether the petitioned action may be warranted.
Present and Threatened Destruction, Modification, or Curtailment of
Habitat or Range
The CBD petition stated the range of the white marlin has been
reduced between the 1960s and the 1990s per Worm and Tittensor (2011).
Other
[[Page 6302]]
information provided by CBD contradicts this range reduction and shows
Worm and Tittensor's (2011) finding to be obsolete: Lynch et al. (2011)
includes a figure summarizing distribution of white marlin in the
Atlantic Ocean from 2000 to 2006 that indicates white marlin occur in
all the areas identified as absent by Worm and Tittensor (2011).
Information in our files (SCRS, 2011; 2012) also indicates the range
has not contracted. Therefore we conclude the petition does not provide
substantial information indicating the range of the white marlin has
been constricted and further note that a slight variation in range of a
species that occurs across the Atlantic Ocean and 70 degrees latitude
would not alone constitute an extinction risk.
The CBD petition states ``studies have found that billfish, such as
white marlin, are sensitive to water quality conditions, which are
rapidly changing as a result of climate change and ocean
acidification'' and refers to Lynch et al. (2011). We reviewed Lynch et
al. (2011) and did not find statements supporting CBDs' assertions.
Further, neither CBD nor Lynch et al. (2011) provide any explanation or
connection of how water quality condition, climate change, or ocean
acidification are operative threats to the continued existence of the
white marlin. We did not find information in our files indicating how
presumed changes in water quality from climate change and ocean
acidification would be an extinction risk of concern to white marlin.
In summary, information presented in the two petitions and in our
files does not constitute substantial information indicating that the
present and threatened destruction, modification, or curtailment of
habitat or range may be causing extinction risk of concern for white
marlin.
Overutilization for Commercial and Recreational Purposes
The CBD petition quotes from Beerkircher et al. (2009) that white
marlin are among ``the most overexploited pelagic fishes.'' The CBD
petition also attributes other statements to ICCAT (SCRS, 2011)
including ``white marlin populations have failed to rebuild, and they
have also continued to decline and landings indicate this continued
decline and the catch-per-unit-effort shows instability in the
population.'' We reviewed SCRS (2011) and could not substantiate or
find support for the statements. In addition, the CBD petition did not
provide any explanation on how these statements correspond to
extinction risk.
The Chambers petition says the status of the white marlin
population ``is well below the level at which there is a danger of
recruitment failure which is considered to begin at 50 percent of
MSY,'' and, ``Passing such a threshold means there are becoming too few
breeders to replace the population which can then spiral ever faster
towards extinction.'' The Chambers petition did not provide any
supporting information for these claims. It included no information or
explanation on how this threshold corresponds to extinction risk. The
petition did not provide information on recruitment failure or the
number of current breeders. We are unaware of data, and did not find
information in our files, to support this claim.
The CBD petition did provide some information on white marlin
population size, somewhat relevant to Mr. Chambers' claims. It cites
the decline in B/Bmsy from 1.02 in 1970 to 0.44 in 2010 (Collette et
al., 2011) as evidence of overutilization of white marlin. B/Bmsy is a
relative abundance metric in fishery management that expresses a
stock's biomass as a proportion of the biomass that would support the
continuous, maximum harvest of that stock. Although it provides B/Bmsy
figures for white marlin, the CBD does not provide any rationale why a
B/Bmsy of 0.44 causes an extinction risk of concern. We do not believe
0.44 B/Bmsy alone is a cause for concern, as it represents fishing
potential rather than absolute abundance, and does not necessarily have
any relationship to a species' extinction risk. In addition, we
interpret the B/Bmsy trend presented in Collette et al. (2011) as
declining between 1970 and 1990, followed by a stable or increasing,
but not decreasing, stock size from 1990 through 2010.
The Chambers petition states white marlin abundance has ``fallen to
about 2 percent of an unfished level of abundance by the end of 2007.''
While population decline can result in extinction risk that is cause
for concern in certain circumstances, the decline described in the
Chambers petition appears to have been derived from reported landings.
Although a decline in reported landings can oftentimes indicate a
decrease in total abundance, in this case it is likely this decline in
landings is a result of the regulations ICCAT has instituted since 1995
to reduce white marlin landings. Therefore, we conclude landings data
do not indicate a decline in white marlin abundance and do not indicate
that white marlin is being negatively impacted by overutilization. We
are unaware of any data suggesting that white marlin have declined to
the level Mr. Chambers claims, which would correspond to a B/Bmsy value
of 0.04 or one eleventh the value presented in the CBD petition.
The CBD petition cites the ``vulnerable'' status classification
made by IUCN to support listing white marlin as threatened or
endangered under the ESA, and includes Collette et al. (2011) as a
reference. As discussed above, risk classifications by other
organizations or agencies (e.g., IUCN) do not alone provide rationale
for a positive 90-day finding under the ESA. However we have evaluated
the IUCN source information for white marlin relative to the ESA
standards of extinction risk and we find the IUCN classification does
not present information that was not already considered in the 2007
status review (e.g., the 2006 ICCAT stock assessment) or that was not
included by CBD in their petition and discussed herein (e.g., range
constriction as described by Worm and Tittensor, 2011 and catch
composition per Beerkircher et al., 2009).
The CBD petition discusses how roundscale spearfish reported in the
white marlin catch can affect ICCAT stock assessments and requests a
new assessment. Citing Beerkircher et al. (2009), the CBD petition
suggests we adopt a proportion of roundscale spearfish to white marlin
in the total catch between 21 and 42 percent and re-evaluate our prior
finding. As previously discussed, the proportion of spearfish in the
total catch identified as white marlin was highly variable and
spatially limited (Beerkircher et al., 2009). In evaluating the
findings from Beerkircher et al. (2009), ICCAT subsequently concluded
reliable estimates on the proportion of roundscale spearfish reported
as white marlin in the catch rates were not available, and elected to
perform a mixed stock assessment until more accurate species
identification and differentiation of species catch were available
(SCRS, 2011). Specifically, ICCAT determined a comprehensive Atlantic-
wide sampling program, as well as a large-scale retrospective analysis,
would be required for a reliable population-level estimate of
roundscale spearfish reported as white marlin (SCRS, 2011). All white
marlin biological material sampled prior to 2006 is currently presumed
to contain unknown proportions of roundscale spearfish (SCRS, 2012). We
acknowledge it is important to consider the ratio of roundscale
spearfish reported in the white marlin catch, however we concur with
ICCAT that it is not possible at this time.

The CBD petition referenced the simulations performed by
Beerkircher et al. (2009) and stated they were an indication of
population decline. The CBD petition does not include any additional
information indicating how these simulations indicate extinction risk.
We carefully reviewed the simulations; we noted they include the period
1955 through 1999 when the marked decline in white marlin catch
occurred, and do not project through subsequent years when bycatch was
stabilized and reduced. Therefore we do not find this simulated decline
in roundscale spearfish concurrent with white marlin surprising, as the
simulations are partitioning the noted decline in one species' (white
marlin) catch rates that occurred through the 1990s across two species
(white marlin and roundscale spearfish). We conclude the simulations do
not provide relevant information regarding the extinction risk of white
marlin or information on the current status of the white marlin.
In summary, the petitions do not present information regarding the
decline of white marlin catches in the 1990s that we have not already
considered in prior determinations as discussed (see ``Species
Description''). There is no information in our files to suggest our
prior conclusions regarding the 1990s decline in white marlin catch
were incorrect or insufficient. We conclude the characterization of
continuing population decline in the petitions is unsubstantiated. The
petitions did not provide substantial information that white marlin
populations are unstable or that species misclassification poses an
extinction risk. Therefore we conclude the petitions do not present
substantial scientific information indicating that listing may be
warranted due to overutilization for commercial and recreational
purposes.
Inadequacy of Existing Regulatory Mechanisms
The CBD petition states Lynch et al. (2011) ``demonstrates that
existing regulatory mechanisms are inadequate to prevent the decline of
white marlin.'' We carefully reviewed Lynch et al. (2011) and could not
find statements supporting CBDs' assertions. In fact, Lynch et al.
(2011) states measures already implemented are likely beneficial to
some degree; in combination, reductions in landing and live release
``should slow and possibly reverse downward population trends * * *
some evidence of population response to these management strategies may
already be observable.'' The Chambers petition states that ICCAT is not
managing the white marlin to produce the maximum sustainable yield, but
does not explain how this leads to extinction risk of concern. Fishery
management targets, such as maximum sustainable yield, and statuses,
are based on different criteria than that required by the ESA and,
thus, do not necessarily have any relationship to a species' extinction
risk. There is no information in our files that indicates the current
regulatory mechanisms are insufficient to prevent endangerment of the
white marlin. The petitions did not present other information to
indicate how the inadequacy of existing regulatory mechanisms is an
extinction risk to the white marlin.
While the petitions state additional regulations are required to
ensure rebuilding of the marlin populations, they do not provide any
explanation on how the existing regulatory mechanisms are inadequate to
prevent endangerment of the white marlin. In summary we find the
petitions, and information readily available in our files, do not
present substantial information to suggest the existing regulatory
mechanisms are inadequate and may be causing an extinction risk for
white marlin.
After reviewing the information contained in the petitions, as well
as information readily available in our files, we conclude these
petitions do not present substantial scientific or commercial
information indicating the petitioned action may be warranted.
