Key EFP Milestones
• 2004 – ‘Full Retention’ • 2005 – ‘Maximized Retention’ • 2008 – ‘Unavoidable Discards’ – return to
port. • General trends:
– Expanding EM ‘duty of care’ requirements – Expanding vessel log data quality
15 February 2013 ©2013 Archipelago Marine Research Ltd.
Key Operational Elements • 2004 – 2006 – Annual technical reports • 2007 – 2010:
– Project operations centralized – Compliance issues defined – OLE more aligned with program – Structured data reports – 100% data archiving – Intensified emphasis on EM Log comparison
• Regular feedback to skippers
16 February 2013 ©2013 Archipelago Marine Research Ltd.
EM Technology Developments • Platform Transition
– Integrated sensor and video data – Improved reliability
• EM Analysis Software • Other
– Data encryption – IP cameras – Up to 8 cameras – Improved sensors – Real time ‘Health Statement’ via satellite
17 February 2013 ©2013 Archipelago Marine Research Ltd.
Program Cost Issues
• Average cost per Seaday – $225-300
• Key Issue – No Tenure – Large mob/demob effort – Annual EM lease cost – Limited infrastructure
• Cost could be 30-50% lower

Summary • EM program provided fine scale data to effectively
monitor full retention compliance, • Data set also better characterizes fishery,
individualize accountability and improve rule design, • EFP was effective for setting regulations, • EFP and EM program together drove significant
change in the fishery.
