Problem: How do we arrive at implementable E-FMPs?

Constraint: SS-FMPs are elaborate treatments on individual species/stocks that tend to stove-pipe management actions and limit EBFM.

EIS


  • Common Assessment Framework across Species

  • Biological/Management Reference Points

    • aka Harvest Objectives - 10% SPR; historical abundance level

    • Trivial (snakeheads bad) to complex (multi-axis reference points)

    • Stakeholder buy-in

  • Stock Assessment (e.g., crab dredge survey; estimates of exploitation and abundance)

  • Control Rules

  • (Decision Support)

    • Thresholds ~ limits

    • Targets ~ optima


  • Challenges/Opportunities:

  • Preserve single species stock assessments as best available science.

  • Develop decision support tools related to

    • Species Interactions

    • Habitat Dependencies

    • Externalities (Disease, Climate, Migration, Catastrophes, Science articles)

  • Build integrative structures (modules) between EB-FMPs that promote EBM by developing common source material and decision frameworks.

    • Source Modules

    • Assessment Modules


Module Approach

Spp

Interactions

Habitat

Source Info

Harvest


  • Source Modules: Reduce redundancy, improve integration.

  • Guild-specific Information

    • ASMFC – Habitat Requirements of Anadromous Fishes (under review)

    • Alaska Fisheries Center – Groundfish FMP

    • NE Center – GIS Maps of multi-spp. habitats.

  • Habitats of Particular Concern

    • SAV-maps, goals, links to fisheries productivity

    • Oyster Reefs

    • Littoral Zone

  • Assessment Modules: Lead to control rules, management actions

    • Changes in harvest policy

    • Changes in habitat policy (more creative thought needed here – mitigation, restoration, fishery reimbursements)

  • Recommendations for EB-FMP development under Chesapeake 2000.

  • STAC, CBO, MDSG, etc. Convene managers and other stakeholders to review and accept science-management framework for EB-FMP:

  • Reference Point Assessment Control Rule.

  • 2. Scientists. Innovate biological reference points, assessments, and decision support tools for Species Interactions, Habitat Dependencies, and Externalities. Continue developing single species exploitation assessments for Bay species.

  • Plan Writers. Develop integrated source documents, Use Habitat modelsand GIS maps to target geographic areas for assessment and control rules, relational databases related to descriptive elements of EB-FMPs.

  • Funding/Research Priorities (CBO, MDSG, DNR, VMRC, ASMFC).

    • Dedicated support for EB-FMP assessment activities.

    • Emphasis on science and assumptions related to carrying capacity (habitat), migration (removals), species interactions (forage spp).

    • Ecosystem Modeling/Indicators/Decision tools.
