INTRODUCTION AND OPENING OF THE MEETING

1.1

Introduction

The International Scientific Committee for Tuna and Tuna-like Species in the North Pacific
Ocean (ISC) was established in 1995 through an intergovernmental agreement between Japanand the United States of America (USA). Since its establishment and first meeting in 1996, the
ISC has undergone a number of changes to its membership, charter and name (from the Interim
Scientific Committee to the International Scientific Committee) and has adopted a number ofguidelines for its operations. The two main goals of the ISC are (1) to enhance scientificresearch and cooperation for conservation and rational utilization of the species of tuna and tunalike fishes that inhabit the North Pacific Ocean during a part or all of their life cycle; and (2) toestablish the scientific groundwork for the conservation and rational utilization of these species
in this region. The ISC is made up of voting Members from coastal states and fishing entities in
the North Pacific as well as coastal states and fishing entities with vessels fishing for highly
migratory species in the region, and non-voting Members from relevant intergovernmental
fishery and marine science organizations, recognized by all voting Members.
At the twelfth Plenary session of the ISC (ISC12) held in July 2012, ISC members agreed to holdan intercessional Plenary meeting in order to resolve outstanding issues. These issues include
finalizing the ISC Operations Manual, as well as adopting the Pacific bluefin tuna assessment
and related scientific advice.
1.2

Opening of the meeting

The intercessional meeting of the ISC was convened via webinar at 2pm (HST) on 19 December
2012 by the ISC Chairman, G. DiNardo. A roll call confirmed the presence of delegates from
Canada, China, Chinese Taipei, Japan, Korea, Mexico, and USA. Representatives from theInter-American Tropical Tuna Commission attended as observers (Annex 1).

ADOPTION OF THE AGENDA

The proposed agenda of the session was considered and adopted with no changes (Annex 2). S.
Shoffler and L. Katahira were assigned lead rapporteur duties. A list of meeting documents is
contained in Annex 3.
There was a recommendation that ISC address WCPFC-SC8 requests, as well as concerns about
ISC reporting requirements, during this session. The ISC Chair reminded Members that the
WCPFC-NC is the only body that can directly task the ISC, and this relationship is outlined in
the existing Memorandum of Understanding (MOU) between ISC and WCPFC.
The ISC Chair reported that all requests and concerns were discussed in detail at the 9th Regular
Session of the WCPFC Commission (WCPFC9) in December 2012. Since WCPFC-NC8
endorsed the request made at WCPFC-SC8 for the ISC to conduct additional analyses associatedwith the striped marlin stock assessment, the BILLWG conducted the analyses and presented
them for review at WCPFC9. The Chair also reported that a potential solution to the concern
over SC reporting requirements raised during WCPFC-SC8, while unfounded, has been5

developed. The ISC would forward assessment reports to the SC as soon as they are approved
and the Plenary concluded. Members were satisfied with the progress and agreed to suspend
further discussion on these topics until ISC13.

PACIFIC BLUEFIN TUNA STOCK ASSESSMENT

Y. Takeuchi summarized results of the stock assessment conducted by the ISC Pacific Bluefin
Tuna Working Group (PBFWG) (ISC/IM12/Annex 4). The Stock Synthesis software (version
3.23b) was fit to the stock assessment input data in a likelihood-based statistical framework.
Maximum likelihood estimates of model parameters, derived outputs, and their variances wereused to characterize stock status and to develop stock projections. A single pan-Pacific stock of
PBF is assumed. The model used quarterly catch-at-length data; 14 fisheries defined by gear,
location and season; and with abundance indices from longline fleets and a troll fleet. The
PBFWG recognized there are substantial uncertainties in the current stock assessment. In
particular procedures used to standardize CPUE and weight the input data, as well as method toestimate selectivities. The influences of these uncertainties on stock dynamics were consideredusing alternative models and characterized by 20 trial runs. While no single model provided agood fit to all sources of data considered reliable, there was a general agreement among models
in terms of key model results. All plausible models depicted large long-term fluctuations inspawning stock biomass (SSB) and a highly depleted stock that has been declining for over a
decade. Model estimates of current biomass are at or near the lowest level; however there is noevidence of reduced recruitment. Estimated age-specific fishing mortalities on the stock in the
recent period (2007-2009) relative to 2002-2004 (the base period for the current WCPFC
conservation and management measure 2010-04) show 4,17, 8, 41 and 10% increases for ages
0,1,2,3 and 4+, respectively (Figure Ex-5). Although no target or limit reference points havebeen established for the Pacific Bluefin tuna stock under the auspices of the WCPFC andIATTC, the current F (average 2007-2009) is above all reasonable target and limit biologicalreference points (BRPs).
The PBFWG offers the following conservation advice:PBF is currently (2010) near historically low biomass levels and experiencing highexploitation levels above BRPs. Extending the status quo (2007-2009) fishing levels is
unlikely to improve the stock condition.
Based on projection analyses the recently implemented WCPFC (entered into force in2011) and IATTC (entered into force in 2012) conservation and management measures, if
properly implemented and enforced, are expected to contribute to the recovery of thestock.
Additional Japanese domestic regulations aimed at reducing fishing mortality are
projected to further contribute to the recovery of the stock.

The ISC Chair thanked the WG for their hard work and noted that it produced a report in very
short order. It was also noted that additional revisions are required before the stock assessment
report can be released. Plenary agreed that the assessment report would be distributed within 60
6

days and an Executive Summary of the assessment report be posted on the ISC website by
January 7, 2013.
Plenary discussed the stock assessment and sought clarification on CPUE series used in theassessment; in particular, whether EPO CPUE associated with the purse-seine fishery had beenused. The PBFWG Chair clarified that the assessment did not use CPUE from the EPO purseseine fishery due to issues concerning the representativeness of standardized CPUE from thisfleet to stock abundance. The WG recognized the importance of the information particularly as it
relates to the development of a spatially explicit PBF assessment model. In the meantime, theWG decided to rely on CPUE series in the WCPO as measures of PBF abundance in the North
Pacific Ocean.
It was noted that the report needs more detail on how CPUE time series were standardized andthe process used for weighting CPUE and size composition data. Plenary noted that the report
also needs more detail on the steepness parameter in the stock-recruit relationship, particularly
the rational and analysis that supports the adopted value (0.999) used in the assessment.
Plenary noted that a Kobe plot was not included in the assessment report. The ISC Chair
indicated that Kobe plots are standard “calculations” in any stock assessment, and the PBFWG
will need to complete that calculation for review and adoption at ISC13. To initiate discussions
on the topic, a Kobe plot using 20% of expected unfished SSB as the biomass reference pointand 20% SPR as the F reference point was computed (not included) and reviewed. In the plots
the recent Kobe trace (2010) was located in the in the upper left quadrant, indicating a stock thatis both overfished and experiencing overfishing, consistent with the stock status determination in
the stock assessment report. In addition, most of the Kobe trace (1952-2010) was restricted to theupper left quadrant, indicating that the stock had been in an overfished and overfishing state formost of the assessment period. Since the Kobe traces do not resemble the usual pattern observedin most Kobe plots (usually starting out with a relatively healthy stock before showing signs ofstress) the validity of the computed trace, as well as possible explanations for the observed
pattern, were discussed There was no resolution on this matter, therefore Plenary tasked the
PBFWG with completing the calculations and recommending a Kobe plot(s) for PBF that is
consistent with the current assessment for review at ISC13. Plausible explanations for Pacificbluefin tuna being in an overfishing and overfished state for most of the assessment period
should also be presented at ISC13.
Stock Status
Based on the reference point ratios, overfishing is occurring (see F-based ratios in Table 1) andthe stock is heavily overfished (see depletion ratios in Table 1). Model estimates of 2010
spawning stock biomass (SSB) are at or near their lowest level and SSB has been declining forover a decade; however, there is no evidence of reduced recruitment.

The current (2010) PBF biomass level is near historically low biomass levels and experiencing
high exploitation levels above all potential biological reference points (BRPs). Extending thestatus quo (2007-2009) fishing levels is unlikely to improve the stock condition.
Recently implemented WCPFC1 (entered into force in 2011) and IATTC2 (entered into force in2012) conservation and management measures combined with additional Japanese voluntary1This refers to WCPFC CMM 2010‐04 which specifies that “total fishing effort by their vessels fishing for Pacific bluefin

tuna in the area north of the 20 degrees north shall stay below the 2002‐2004 levels for 2011 and 2012, except for
artisanal fisheries. Such measures shall include those to reduce catches of juveniles (age 0‐3) below the 2002‐2004 levels,
except for Korea. Korea shall take necessary measures to regulate the catches of juveniles (age 0‐3) by managing Korean
fisheries in accordance with this CMM. CCMs shall cooperate for this purpose.” For full text see:
http://www.wcpfc.int/system/files/documents/conservation‐and‐management‐measures‐and‐resolutions/conservation‐and‐management‐measures‐/CMM%202010‐04%20%5BPacific%20Bluefin%20Tuna%5D%2004112011.pdf
2This refers to IATTC Resolution C‐12‐09 which specifies that “1. In the IATTC Convention Area, the commercial catches of
bluefin tuna by all the CPCs during the two‐year period of 2012‐2013 shall not exceed 10,000 metric tons; 2. The
commercial catch of bluefin tuna in the commercial fishery in the Convention Area shall not exceed 5,600 metric tons8

domestic regulations aimed at reducing mortality3, if properly implemented and enforced, areexpected to contribute to the recovery of the stock. Based on those findings, it should be notedthat implementation of catch limits is particularly effective in increasing future SSB when strong
recruitment occurs. It is also important to note that if recruitment is less favorable, a reduction of
F could be more effective than catch limits to reduce the risk of the stock declining.
The ISC requires advice from the WCPFC regarding which reference point managers prefer sothat it can provide the most useful scientific advice. Until which time a decision is rendered, theISC will continue to provide a suite of potential biological reference points for managers toconsider.
Future work
To finalize the PBF stock assessment report by February 21, 2013, Plenary tasked the PBFWG
with the following:
1. Clarify how the WG dealt with data weighting of the size composition data and how
CPUE standardizations were conducted;
2. Clarify justification for the adopted steepness value used in the assessment;
3. Move figures to the back of the executive summary
The Plenary also requested that the PBFWG Chair work with the ISC Chair to develop a strategy
for prioritizing and completing the following tasks for presentation and review at ISC13:
1. Conduct additional projection scenarios with recruitment levels consistent with the lower
values estimated in the 1980s;
2. Pending approval from the WCPFC-NC, conduct reference point research similar to thatbeing conducted for North Pacific albacore and swordfish (see item 4 WCPFC-NC8);
3. Conduct fishery impact analyses to determine the extent to which gears are contributing
to the overfishing and overfished status;
4. Develop and recommend Kobe plot(s) based on results from the current Pacific bluefin
tuna stock assessment. Provide plausible explanations for PBF being in an overfishedcondition throughout the entire assessment period.

WCPFC-NC8

ISC reviewed the NC8 (Nagasaki, Japan; September 2012) request to provide information for
determining appropriate reference points for both North Pacific albacore and swordfish(ISC/IM12/PLENARY/01). Plenary endorsed the requests and tasked the ALBWG and
BILLWG, respectively, with completing the assignments and presenting the results for review atduring the year 2012; 3. Notwithstanding paragraphs 1 and 2, any CPC with a historical record of Eastern Pacific bluefin
catches may take a commercial catch of up to 500 metric tons of Eastern Pacific bluefin tuna annually.” For full text see:

ISC13. Plenary also agreed that conducting similar work for Pacific bluefin tuna and stripedmarlin would be appropriate and the ISC Chair agreed to seek approval on this matter from theNC. If accepted the results would be presented and reviewed at ISC13. The Plenary also agreed
that it would be beneficial to address reference point considerations for these species even if nopositive feedback is received from the NC.

ADMINISTRATIVE MATTERS

5.1

Updates to the ISC Operations Manual

ISC has been working to update its Operations Manual (ISC/12/Plenary/05) in order to clarifyroles and tighten procedures. Members were asked to consider these changes and consider
adopting the revised Operations Manual (July 2012). ISC12 Plenary generally endorsed the
updates, but asked for more time for Members to review the changes. It was agreed that thechanges would be finalized at the 17-21 December 2012 intercessional Plenary meeting
including edits to the section on Best Available Scientific Information (BASI) that recommend
ISC support and adopt the use of BASI whenever possible (ISC/IM12/PLENARY/02). The
December Plenary adopted the changes to BASI and the ISC Chair agreed to incorporate
additional changes submitted by Members for other sections of the Operations Manual for
circulation prior to ISC13. The ISC Chair was asked to report on the progress of ISC
membership documentation that was discussed at ISC12. It was reported that the Office of the
Chair is still researching this matter and will provide a full report at ISC13.
5.2

Plenary Observers

Recently an environmental non-governmental organization (eNGO) requested to participate as anobserver in the November 2012 PBFWG Workshop in Honolulu, Hawaii. Because working
group participants are appointed by Members and must possess credible scientific and fisheries
qualifications and actively contribute to the WG proceedings, their request was denied. Because
ISC may receive additional requests from other NGOs, including industry groups, to observe ISC
Plenary meetings, the ISC discussed if and how Observers can participate in the meetings, as
specified in the ISC Operations Manual under Procedures. (ISC/IM12/PLENARY/03)
Plenary agreed that observers should be able to participate at Plenary and that the ISC Chair
would develop rules and procedures for their participation. It was noted that because ISC is an
RFO (regional fishery organization) it is not under the same dictate as RFMOs (Regional Fishery
Management Organization) that require transparency for management decision making. Plenary
agreed that the rules and procedures would include the following:Advocacy documents are not appropriate for a science organization and ISC will not
accept them.
Plenary may include a single short comment period for observers with comments limited
to technical questions about ISC assessments and procedures; they will not include
presentations or positions by observers.
Observers will be subject to rules of conduct.
Observers wishing to attend Plenary meetings will have to apply to the ISC Chair well in
10

advance of the meeting (at least 60 days), and any Member can oppose the application.
The ISC Chair will prepare rules for review and adoption by Members in time for them to be
implemented for ISC13. Plenary noted that by allowing observers additional costs, in the form ofadded space and administration, will be incurred. This cost will likely be borne by the Member
hosting the Plenary meeting.
5.3

ISC Review Update

The ISC Chair discussed the status of the independent ISC Function Review, and indicated thatthe final report is expected to be complete by late February 2013. The report will note that ISC is
unique in its science role in the Pacific Ocean, provide recommendations for incorporating BASI
and a process for standardizing reports, and recommend procedures to elevate the stature of ISC
in the scientific community.
5.4

Delegation Updates

The Chair noted some changes to the ISC delegations specifically that Dr. Xiaojie Dai now heads
the China delegation. It was noted that Heads of Delegation contact information was circulated
to all Delegation leads.
5.6

Other Matters

The Chair noted that several countries had not yet provided complete data for the blue sharkassessment and that data should be provided to the Chair of the SHARKWG immediately.
