2007 2008 2009 2010


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


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


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


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

Hake EM 2005 Total Project Effort


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.
