Take Aways
• We need to do, and are committed to doing,
Ecosystem-based Fisheries Management
• Science-based Options exist to do EBFM, and can
be inserted into LMR management, now
• The risks of not doing EBFM are not fading

3 Levels of Marine Ecosystem Management (in relation to fisheries)
1. Ecosystem-Based Management (EBM)
– multiple ocean use sectors are discussed and strategic
decisions made as to various tradeoffs among sectors
2. Ecosystem-Based Fisheries Management (EBFM)
– has facets of both strategic & tactical decisions solely
within the fisheries sector
3. Ecosystem Approach to Fisheries (EAF)
– adds ecosystem factors into fisheries stock assessments
for tactical management decisions

Some Benefits of EB(F)M
• More information to bear on management decisions, which
should improve our ability to sustainably manage fisheries.
• We will have increased predictability of management actions.
• More stability of ecosystem levels measures,
• translates into better regulatory stability and business plans
• Facilitates trade-offs, balancing social and ecological needs

Are We Allowed to Do Ecosystem Based
Management?
• Numerous mandates drive
how we manage Marine
Fisheries & Ecosystems in
the US.
• Able to do EB(F)M under/
within existing mandates.
• Need to do EBM to
address all mandates

Moving Forward
• Ecosystem-Based Fisheries
Management is feasible now
• Ecosystem-Based Fisheries
Management requires that we
directly confront tradeoffs
