SCRS interseasonal meetings (N days)
• concerns over the increase in number and length of inter-sessional scientific meetings;
• the current workload for both SCRS and the Secretariat would be difficult to maintain with the current human resources.
• The majority of the meetings are scheduled in response to the work determined by the Commission.
• The use of more complex assessment models (e.g., integrated statistical models) implyies higher burden of work in both the preparatory and assessment processes:
• more time and focus than is possible in a typical 7-10 day assessment workshop meeting • much additional time in assembling and preparing the data streams needed to support
these models
• 11 intersessional meetings • 71 days

• SCRS has instituted the process of conducting a data preparatory meeting in advance of a stock assessment workshop, developing new procedures for the preparation of data and analysis (i.e., CPUE procedures in 2012) and utilizing electronic communication mechanisms to facilitate intersessional collaboration to attempt to alleviate the difficulty. [Not sufficient!]
• Other tRFMOs which most commonly apply these approaches: the Secretariats have significantly larger SA and DB management staff which is used to centralize these functions.
• SCRS reiterates its recommendation that further additions to data management staff at the Secretariat should be made to address current and future demands, which are likely to increase further.
• “The implementation of the more complex models (MFCL and SS) is not well suited to the
collaborative development of an assessment in the working group environment. These models require considerable development, evaluation and testing by dedicated assessment personnel” (ALB peer review [SCRS/13/171])
• SCRS Science Strategic Plan [2015-2020]: provides the appropriate framework for this debate

Background:
• 2011 meeting of the WG on the Organization of the SCRS (Anon., 2012) identified a set of priorities regarding Research & Development investments, participation of CPC national scientists, capacity building, quality assurance and transparency.
• Resolution on Best Available Science [Res. 2011-17]. The Resolution proposes a set of actions affecting to the different links in the chain of the development of the scientific advice: quality assurance, including aspects in the sphere of collection of data, research, participation and capacity building, Dialogue with the SCRS and, very particularly, quality control of the stock assessments and advice.
• 2012 ICCAT Working Group On Stock Assessment Methods • [SCRS/2012/40] “IMPLEMENTATION OF BEST SCIENCE IN THE SCRS” proposed the elaboration of
the 2014-2020 SCRS Science Strategic Plan. • Recommendation of the 2012 WGSAM: “During 2013 the 2014-2020 SCRS Science Strategic Plan
(including Quality Assurance, Capacity Building and Code of Conduct text,) should be developed by the SCRS.”
• 2012 SCRS meeting “It is therefore proposed, starting in 2013, to develop a draft Strategic Science Plan which will be considered at an ad hoc meeting of the SCRS. This will be peer reviewed before approval by SCRS and adoption by the Commission. The importance of the plan and its development was agreed.”

Background:
• 2013 ICCAT Working Group On Stock Assessment Methods • [SCRS/2013/24] “A PLAN FOR THE PLAN” outlined an approach for identifying key research needs
and components of and a roadmap for developing the 2015-2020 SCRS Strategic Plan • Recommendation of the 2012 WGSAM: “WGSAM endorsed and recommended the plan outlined in
SCRS/2013/024.
• 2013 SCRS meeting “The SCRS agreed that the Strategic Plan was an excellent proposal and noted that ICCAT will be the only tRFMO that will have such a holistic scientific vision”

Components of the SCRS Strategic Plan:
Period 2015-2020 Mission: Outline the purpose of the SCRS, in line with the Rules of
Procedure defined in the ICCAT Convention, its values and the necessities of the Commission. In other words, define “what business are we in?“
Vision: A statement describing where the SCRS desires to be in 2020; the target around which we pursue to focus the attention and energies of the SCRS.
SWOT Analysis: Strengths – Weaknesses – Opportunities – Threaths
Values: The guiding principles of the SCRS, including the elaboration of a code of conduct.

Goals: The goals are broad priorities for the SCRS. Objectives: Closely tied to goals. Specific and measurable milestone that must be achieved in order to reach the goal Strategies: Within each goal should be strategies, initiatives, projects and priorities that will advance the goal. Tactics, Performance measures: To accomplish the goals applying strategies identified, the plan should include accountability and performance measures. Identify who (i.e. SCRS, Secretariat, CPCs and Commission) is responsible for which elements, how success will be measured and by when (interim dates and deadlines).

Why a dialogue between SCRS & COM? [Res 11-17] Resolution by ICCAT on Best Available Science: Take all measures which would be appropriate…To improve the communication between CPCs, the Commission and the SCRS by enabling a constant and regular dialogue. 1st WG Convention Amendment [Sapporo, 2013]: In the context of the Precautionary Approach, one CPC highlighted the importance for the Commission to develop clear Harvest Control Rules (HCR) for the stocks managed by it. There was broad support for the Commission to consider this matter at the upcoming annual meeting.
2013 Meeting on Bluefin Stock Assessment Methods [Gloucester, 2013]: Conduct a ‘side event’(SCRS Chairman to co-ordinate) at the 2013 Commission meeting open to CPCs and stakeholder groups, drawing upon the experience at CCSBT to initiate the management /science/ stakeholder dialogue.
[Rec. 11.02] & [Rec. 11.04]: North Atlantic swordfish & North Atlantic Albacore … the SCRS shall develop a Limit Reference Point (LRP) for this stock. Future decisions on the management of this stock shall include a measure that would trigger a rebuilding plan, should the biomass decrease to a level approaching the defined LRP as established by the SCRS.

Reference Points (RP)
• RPs are guidelines for management; can be: • exploitation rates or biomass based; • model or empirical based
• Target Reference Points (TRPs): values for
stock size and/or fishing mortality rate that a manager aims to achieve and maintain.
• Threshold Reference Points (TrRPs), which identify a predefined management response.
• Limit Reference Points (LRPs), which describe an undesirable state of the indicator that should be avoided with high probability.

• Commission: identify management objectives and HCR that aim to achieve those objectives, define RPs, performance indicators, and also define the level of risk that is acceptable
• SCRS: help to define the LRP and the associated acceptable level of risk, as this is strongly influenced by the biology of the stock; conduct the stock assessments that inform on the status of the stock relative to RPs.

• It takes no full account of UNCERTAINTY (the model selected may not constitute the best representation of the actual resource dynamics)
• While projections based on the « best assessment » can take account of quantified uncertainty (e.g. model estimation errors & future R variability), projections typically are based on constant C of F assumptions.
• Projections of this nature do not necessarily capture the full range of uncertainty and thus may inaccurately represent risk.

Management Strategy Evaluation (MSE)
Providing scientific advice with the MSE approach: • MSE requires evaluating all aspects of a management strategy: data to be
collected, methods of analysis, management actions, and uncertain consequences of the these actions (implementation error).
• MSE helps identify management strategies that are robust to uncertainties in the stock assessment.
• HCRs with their ability to translate predetermined RPs and fish stock status into fishery management actions, is one of the essential components in MSE
• A vast majority of fishery scientists consider MSE to be a dominant issue in the future of fisheries stock assessment.
• MSE acts as a healthy antidote to the “Pygmalion effect”.

Management Strategy Evaluation (MSE)
Providing scientific advice with the MSE approach: • It was developed more than 20 years ago; it has been used by the International
Whaling Commission, CCAMLR, CCSBT and has been adopted as a standard fisheries tool in South Africa, New Zealand, Australia, EU…
• The strength of the approach is that instead of using a single model to find an optimal solution, multiple candidate models are put forward to evaluate alternate hypotheses.
• The other core strength of the process is that it is consultative - both managers and stakeholders can have input into the candidate models and management scenarios. As the approach demands clear objectives to do the evaluations against, the method forces participants to be clear about their objectives and to specify performance indicators to quantify whether goals have been achieved.

Part of the MP includes a decision about the “Data” to be collected and used.
Many current stock assessment processes end there, but the MSE paradigm insists that any useful MP should be tested by simulation before it is applied in practice.

Work plan for the Working Group of Stock Assessment Methods • The evaluation of LRP and HCR through the use of MSE is increasingly being recognized by
global tuna RFMOs as an effective means to advance their fishery management process.
• The 2013 assessments of albacore and swordfish were used as examples of how an MSE process could possibly be formally included in the management of those stocks.
• The WGSAM plans to continue this effort by 1) continuing to refine the methods within the MSE process, 2) introduce MSE more assessments when and where appropriate, and 3) foster lines of communication that keep managers informed of their benefits and
weaknesses
Work plan for ALB & SWO The main objective will be to prepare the next assessments for these stocks (not scheduled yet), by reducing uncertainty around datasets and parameters on one hand, and developing robust management procedures that cope with the uncertainty that remains.

• Review of fisheries and biological data submitted during 2013 (SCI-008)
• Improvements in T1 data reporting (catch and fleet statistics) probably related to the Data Report Card (DRC) and its implications for compliance; but DRC has limited utility in identification of data gaps which should be addressed.
• Improvements in T2 data. • However it was noted that there are numerous gaps in these data
which should be identified and rectified, where possible.
• Need to recover and report actual size frequency samples in addition to raised CAS.

A Burden on the Secretariat: How much data to process?
In 2013, a considerable volume of data were handled by the Secretariat, much of which represented revisions of data previously submitted, presumably to meet compliance deadlines and subsequently revised to reflect a more representative view of the real fishery performance. This practice increases the burden on the current staff at the Secretariat.

• The response rate to the obligation to report on national observer programs continues to be quite low.
• The Secretariat has received on average 14 responses over the past two years to the requests for information circulated to CPCs (not all in theformat specified in Form CP45)
• The information provided in the Appendix 2 of the Secretariat Report on Statistics and Coordination of Research (SCI-008) both this year and in 2012 reflects if the specified information is being collected. It does not imply the data are available to the Secretariat at this stage although several CPCs have sent their actual observer data in the format in which it is captured by their national programmes.
• During 2013, the Secretariat has updated the forms; they should facilitate the submission of both aggregated and highly dis-aggregated data to accommodate the needs of individual CPCs.
• The Sub-Committee recommended this standard form, once adopted by SCRS, be made available to all CPCs to standardise the submission of observer data and facilitate its incorporation into a database to be maintained by the ICCAT Secretariat.

• [Rec. 11-10], among other items, requires for artisanal fisheries that are not subject to ICCAT’s [Rec. 10-10] or [Rec. 03-13] that CPCs implement measures to collect by-catch and discard data through alternative means and describe these efforts in their Annual Reports, beginning in 2012. The SCRS shall evaluate these measures in 2013 and provide advice to the Commission on this matter.
• Limited information has been provided on this particular topic thus far, possibly due to complications in addressing this issue as noted in section 16.13.
• Shore-based sampling of landings would provide an adequate method to document and characterize catch composition and disposition.
• Electronic observation systems was recommended as an approach that could be used to supplement and, in some cases, substitute for human observers.

• The Sub-Committee recommends that CPCs take steps to assure that Statistical Correspondents are fully versed and equipped to meet data reporting obligations and that those individuals attend the Sub-Committee on Statistics annual meeting, at a minimum.
• Identify better ways to characterize uncertainty in unquantifiable aspects of data submissions (related to quality control). An inter-sessional discussion on refining the methodology and evaluating additional methods to characterize this uncertainty will be held.
• More focused discussions on artisanal fisheries data-collection be conducted intersessionally. Strategic investments in the short-term may make improvements, but more discussion needs be carried out to avoid duplication and improve utility.
