SSC State of the Ecosystem Working Group
Objective: make better use of existing ecosystem information presented each year, and develop more tailored products and processes to use this information in management
Possible tasks for this WG include:
- Review and prioritize current ecosystem indicator work (analyses of indicators/groups, thresholds, etc) for the 2022 SOE report or prototype stock specific reports
- Develop and test decision frameworks that use ecosystem information in setting Acceptable Biological Catch (ABC) for individual stocks
- Provide scientific support for MAFMC's comprehensive review and update of EAFM risk assessment, and for the Council's use of SOE and risk assessment in strategic planning.
4 / 6
Seeking Council Feedback
What types of ecosystem data/information, tools, or approaches may be missing or would be informative to help support Council decision making, strategic planning, and priority setting (management and research)?
Examples
- The North Pacific Fishery Management Council has used Ecosystem Status Reports to inform OFL and ABC setting for coming years (Bering Sea pollock 2006, Gulf of Alaska cod 2018-2019)
- California Department of Fish and Wildlife utilizes habitat compression and forage indices to inform their Risk Assessment and Mitigation Program for humpback whales, blue whales, and Pacific leatherback turtles

SSC Proposal in Progress
- Includes stock specific and ecosystem level processes, co-develop with stock specific reporting (ESPs)
- Overfishing Limit coefficient of variation (OFL CV) can include both
- Multispecies and system level decisions to be considered for development

- Overfishing Limit coefficient of variation (OFL CV) can include both
- Multispecies and system level decisions to be considered for development
- Potential analyses: OFL CV
- For selected stocks and/or general life history types
- Which ecosystem factors affect uncertainty in current stock biomass and Fmsy?
- Conceptual model mapping ecosystem factors to stock processes
- Which current ecosystem indicators best match relevant ecosystem factors?
- Empirical or simulation analysis: do changes in those indicators predictably change uncertainty?
- Coordinate with with upcoming research track assessments
- For selected stocks and/or general life history types

- Identify initial priorities in collaboration with Council
- Are there multi-indicator thresholds suggesting when FMP level management needs to change?
- Are there changes in ecosystem productivity that imply standardized approaches for
- Setting reference points?
- Developing rebuilding plans?
- Other analyses requiring short-term projections?
6 / 6
Under this short term objective, the SSC ecosystem group would first outline a set of hypotheses for which ecosystem factors would be reasonably expected to affect uncertainty in OFL for a range of life history types or selected individual stocks. A conceptual model mapping ecosystem factors to stock attributes and stock assessment components directly affecting OFL would be constructed to focus on the most relevant considerations for OFL CV. NEFSC staff (EDAB and others as appropriate) would match the ecosystem factors to existing ecosystem indicators, or identify information to develop new indicators if necessary. The SSC ecosystem work group would then collaborate with NEFSC staff to develop analyses relating changes in selected ecosystem indicators to increases/decreases in OFL uncertainty for general life history types, individual stocks, or both. Coordination with specific upcoming research track assessments is also possible.
We propose a longer term objective of developing prototype processes to provide multispecies and system level scientific advice appropriate for Council decision making, in particular where there are multispecies and multifleet tradeoffs linking directly to economic and social outcomes. This is obviously more complex, and requires collaborative work with the Council and Council staff to identify initial priorities with concrete endpoints. One suggestion from the working group was to evaluate thresholds across multiple indicators that, if crossed, might cause the Council to reconsider broad management objectives at the FMP level or across FMPs. Another suggestion could be to address ecosystem productivity comprehensively across stocks in estimation of reference points and approaches for short term projections as well as rebuilding plans.
