1 / 13

This paper reviews example cases where scientists have had success in using ecosystem analysis and modeling to inform management priorities and stakeholder activities, and identifies practices that help bring new ecosystem science information into existing policy processes.

New England Herring MSE: strategic advice

Models quantitatively linked to performance metrics, management objectives

  • Tern productivity at 1.0 or above > 90% of the time
  • Herring biomass > 90% of SSBmsy
  • Fishery yield > 90% of MSY
  • AND fishery closures (F=0) < 1% of the time.

Conclusions

  • Broad suite of tools needed that can address

    • Biophysical factors
    • Stock/species interactions
    • Social and economic factors

  • Must plug into policy-making process

  • Consider fisheries and other mandates (habitat)

  • Communication essential

    • Among modelers
    • Between modelers, managers, and stakeholders

  • Iteration helps

    • With stakeholders and managers for particular projects
    • Annual products such as ESRs
