Electronic Monitoring ProgramPacific States Marine Fisheries Commission
66th Annual Meeting September 23, 2013Coeur d'Alene, Idaho
Dave Colpo
Why are we here?
To test the viability of Electronic Monitoring (EM) as a source of data to document individual accountability of
catch and bycatch in the Pacific Trawl Rationalization Program.
Pacific Fisheries Management CouncilDecision from April 2013 Council Meeting
“The Council indicated their desire to move ahead with consideration of electronic monitoring (EM) by stating that compliance monitoring, rather than the collection of biological data, would be the primary focus for EM in the trawl catch share program[...]”
Is it Science or Compliance?

Issue – 5. Data review time / Cost
• Data collection mechanism (affects % review of video)– Video data (100% Review)– Self-reported catch and discard (logbook) (< 100% Review?)
• Trawl: Mirrored retained federal logbook for discard reporting• Fixed gear: Used Oregon FG logbook as a template• At-sea Catcher Vessel: New logbook to capture location of haul,
retained and discarded weights.
• Speed results are needed– Frequency of data retrievals
• Will a shoreside CM, tech, or the skipper be allowed to pull own drive?• Confidentiality concerns (encryption)
– % review of video
Issue – 4. Definitions of Catch and Discard
13
I. Logbooks as data collection mechanism
I. PSMFC receives Logbook at landingII. Logbook catch data into a database within 72
hoursIII. Vessel Account System hits logbook database for
discard debits
So far, 100% self-reported

I. Logbooks as data collection mechanismII. Video for auditing
Video is reviewed to confirm accurate reporting on the logbook
Still to be addressed:I. Frequency of hard drive retrievalsII. % of video to be reviewedIII. Speed of video review
Vision
15
I. Logbooks as data collection mechanismII. Video for auditingIII. Emulate CM/eTix protocols to check haul
and species level reporting
I. Trip passes if logbook record is “good enough”II. Trip gets flagged if not

1. What is the data source? Logbooks or Video?- If logbooks:
- What % of video is audited?- What is a “good enough” match?- What happens if the match is not good enough?
2. How fast are the reviewed data needed?3. What are the definitions of terms (maximized
retention, catch, discard, etc)?4. Quantifying discards only or both retained and
discarded?5. What about halibut mortality?
