  1. CBO Blue Crab Assess/FMP. ASMFC Bluefish FMP ASMFC Striped Bass FMP ASMFC Alosa FMP ASMFC Croaker FMP ASMFC Menhaden FMP 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.

  2. FMP-Structured Management Stock Structure/ Regional concerns Stock Monitoring Stock Assessment/ Reference Points Fisheries/ Management Life History/ Demographics Habitat/Diets/ EFH~HOPCs Ecosystem considerations EIS

  3. 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

  4. 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

  5. Module Approach Spp Interactions Habitat Source Info Harvest

  6. 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)

  8. Translating Water Quality Control Rules to Living Resource Currency How far are we out of compliance? What are consequences and costs?

  16. Climate Trumps! Warming up the Bay by 1ºC - July Average year Average year plus 1ºC

  17. 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.
