Project challenge
  • How do we include the full range of stakeholders
    in a process that conserves the resource and
  • Benefits from stakeholder knowledge
  • Is scientifically-based
  • Reflects stakeholder preference
  • Results in increased acceptance and compliance
    with management, and improved stakeholder-manageme
    nt interactions

8
The players and their roles
  • Informed stakeholders
  • Provide a vision for the future of the resource,
    identify and evaluate options for achieving that
    vision
  • Scientists
  • Provide quantitative and qualitative tools that
    permit stakeholders to evaluate the efficacy of
    alternative options
  • Facilitators
  • Manage the process to ensure full, open
    participation and representation of all
    stakeholder views
  • Managers
  • Receive results of process and provide guidance
    on legal and practical constraints

9
Case StudyKing mackerel (Scomberomorus cavalla)
  • Recreationally and commercially important
  • Management changes were likely to be made
  • Stakeholders and managers were welcoming of our
    involvement

10
Biology
  • Mobile coastal pelagic piscivore
  • Highly variable growth
  • Sexually dimorphic
  • Maximum age 26 2-10 Typical
  • Warm Water gt 20ºC
  • Supports extensive commercial (40) and
    recreational fisheries (60)

Workshop process
  • Four stakeholder-centered workshops to develop
    model, explore alternatives, and develop
    recommendations
  • Focused on developing recommendations that the
    angling community could implement voluntarily or
    could be implemented by management

12
Stakeholders
  • Recreational anglers
  • For-hire operators
  • Commercial fishermen
  • Environmental NGO representatives
  • Managers and biologists
  • Tackle shop owners
  • Tournament organizers

13
Stakeholder vision statement
  • A sustainable Atlantic king mackerel fishery
    should be managed to prevent overfishing from
    occurring, prevent the species from being
    overfished, to ensure optimum yield is not
    exceeded, while maintaining the genetic diversity
    of fish and providing acceptable levels of access
    and allocation for all sectors while conserving
    biological and ecological functions.

14
Stakeholders goals
  • Achieve the vision (population, fishery,
    ecosystem)
  • While simultaneously
  • Maximizing access
  • Reducing/simplifying regulations
  • Improving stakeholder interactions with
    management and each other
  • Improving stakeholder education

15
Options
  • Management
  • Size limits
  • Bag/creel limits
  • Season limits
  • Constant quota control rule
  • Area closures
  • Voluntary
  • Increased catch and release fishing
  • Reduction of catch and release mortality

16
Performance measures
  • Spawning stock biomass (biomass of mature
    females)
  • Proportion of the population older than 15 years
  • Average age of spawners
  • Harvest (numbers)
  • Yield (lbs)
  • Harvest in preferred size categories
  • Average size in harvest
  • Proportion of year fishery is closed
  • Number of dead fish due to release mortality

17
Weighing options
  • Stakeholders used results from a numerical
    simulation model to weigh the performance of
    different options they suggested in achieving
    their desired goals subject to the constraint of
    minimizing season closures and staying within
    Federally-mandated thresholds
  • All phases of the model development and
    evaluation were discussed and agreed upon by
    consensus of stakeholders

Model Structure
  • Model tracks
  • Males and females separately
  • Ages 1-19
  • Fork lengths 12-63 in (30-160 cm)
  • Two areas, mixing zone and Atlantic non-mixing
    zone (with migration between them)
  • Seasonal time step (Jan.-March, April-June,
    July-Sept., Oct.-Dec.)
  • 3 fisheries

20
Model Processes
  • Growth Maturity
  • von Bertalanffy - Separate patterns for males and
    females
  • Model only includes female maturity
  • Stock-Recruitment
  • Beverton-Holt - Depends on the biomass of mature
    females in both areas
  • Mortality (size-based)
  • Natural
  • Fishing
  • Migration

21
Model Structure
  • Abundance
  • Mortality
  • Catch
  • N Abundance F Inst. Fishing mort. Rate
  • M Natural mort. Z Total mort.
  • p migration rate
  • y year s season
  • a age x sex
  • o area f fishery

22
Parameter uncertainty
  • Simulations drew from parameter distributions
    that reflected either
  • Scientific uncertainty
  • System uncertainty
  • Recreational F used 3 scenarios either
    increasing, constant and decreasing scenarios
    with white noise variability (lognormal CV 10)
  • Ran multiple simulations to yield distributions
    of outcomes

23
Sample results for stakeholders
  • Stakeholders were provided with histograms
    summarizing distribution of results of 300 runs
    of the model options for each performance measure
  • Stakeholders could evaluate mean response and
    extremes so they could avoid undesirable
    conditions

24
Building consensus
  • Consensus developed by iterative voting on a 4-pt
    scale, following discussion and revision of any
    proposed stakeholder motion
  • Consensus history reported live on-screen during
    discussion
  • Consensus reached when 75 of votes are 3 or 4

Acceptability Ranking Scale 4 acceptable, I agree 3 acceptable, I agree with minor reservations 2 not acceptable, I dont agree unless major reservations addressed 1 not acceptable
25
Consensus example
Unanimous consensus was reached on most motions
relatively quickly, but not always
A.7. The FishSmart stakeholder process should be
a part of the Council decision making process for
all fisheries.

  • Members Comments and Reservations (November
    2008)
  • This is too presumptuous. Can be part of a
    presentation to the Council
  • For all fisheries

26
Criteria for recommending options
  • Option had to have a gt 50 chance of ensuring the
    stock was not overfished, nor experiencing
    overfishing over the next 15 years
  • Option must limit season closures
  • Option must meet or exceed the 75 consensus
    threshold

Status of FishSmart recommendations
  • Recommendations were presented to the SAFMC
    Statistical and Scientific Committee and to the
    full Council in December 2008
  • Council voted to add FishSmart recommendations to
    the SSCs list for public scoping
  • Decision expected Summer 2009

29
Benefits Magnusson-Stevens
  • The FishSmart process was an explicit decision
    analysis that included both scientific and
    management uncertainty
  • Separate recommendations could have been
    generated based on
  • Scientific uncertainty (ABCs)
  • E.g., recruitment dynamics
  • Management uncertainty (ACLs)
  • E.g., Change in angler behavior in response to
    regulations

30
Benefits General
  • Process led to better decisions
  • More buy-in from stakeholders
  • Structured stakeholder involvement education
  • Less conflict among stakeholders
  • New partnerships among stakeholders
  • Increased stakeholder satisfaction
  • New collaborations with research and management

31
Lessons learnedCommunication
  • Demands clear, open communication to develop
    trust and respect with and among stakeholders
  • Commitment to explanations without jargon
  • Research team external to the management process
    beneficial
  • Professional, neutral and experienced
    facilitation team is essential

32
Lessons learnedManagement involvement
  • A management request to use the process helps
    ensure stakeholder participation
  • Managers are involved as a stakeholder who can
    supply logistic and legal constraints
  • Management must listen to the outcome
  • If managers choose not to implement workgroup
    recommendations, they must provide clear reasons
    to avoid alienating stakeholders
  • FishSmart is a long term approach it cannot
    solve short-term problems

33
Lessons learnedStakeholder identification
  • Relevant stakeholder groups represented
  • Determining workgroup members is critical
  • Representatives must have clout within their own
    group
  • Effective representation ensures
  • Knowledgeable of key concerns
  • Disseminate results buy-in
  • Minimize size cost
  • Stakeholder interest groups must be balanced
  • Members must be able to work within the process
  • Commit to attending all meetings

34
Lessons learnedStakeholder involvement
  • Commitment to involving stakeholders at all
    stages
  • Stakeholders must understand model to believe in
    it
  • Implications of the results must be openly
    discussed and evaluated
  • When this happens stakeholders become passionate
    advocates for the process

35
Potential for other applications
  • Other fisheries case studies under consideration
  • Pacific rockfish
  • Snook
  • Blue crab
  • Establishing ecosystem targets and thresholds
  • Conflicts between ecosystem services and fisheries

Time line and costs
  • We completed the king mackerel process in 4
    meetings in 8 months.
  • 4 meetings per year is appropriate
  • More contentious issues will require more
    meetings and hence more time
  • King mackerel meetings cost 40k per meeting
  • 20k hotel, food, meeting expenses
  • 12k facilitation team
  • 10k overhead
  • 100k.yr-1 project costs in addition to meetings
  • 20k.yr-1 PI salaries
  • 60k.yr-1 Programmer, Admin support
  • 24k,yr-1 Overhead

38
Other
  • Facilitation team is critical
  • The facilitation team must be independent of
    management
  • Must be involved in all meetings
  • Research team must be viewed as independent
  • Cannot be seen to have an agenda
  • Must respond to all practical requests from
    stakeholders
  • Workgroup lt 30 stakeholders
  • Larger workgroups do not develop cohesion

Starting Abundance
  • Used estimated abundance from Base assessment
    model for Atlantic migratory group

54
Starting Fishing Mortality
  • Commercial and recreational fishing mortality
    rates were chosen so catches in the first year of
    the model were similar to estimated catches in
    2006
  • Estimates for the tournament fishery were
    developed by scaling up the number of tournaments
    by an average number of fish caught per
    tournament
