Information Management and Quality - Workshop IVScenarios

Best Case Scenario
• Vessel report has —matching dealer report
—which matches to dockside monitor’s report
—which matches to trip end hail
• Pounds by species from vessel report are similar to summed pounds by species from dealer report
• Dockside monitor report has similar weights as vessel report and is the same as tally sheet and final dealer report from SAFIS

ACE Utilization Calculation
• Apply discard rates by species/stock/gear/mesh• Details on calculations provided in Workshop I
—Discard Estimation for use in Weekly Sector Catch Reports -- Illustrative examples (posted in WS I web site)
• Result is trip’s ACE utilization• Sum all trips for week by species and stock area to
create Sector Manager’s Weekly Report

Not Best Case Scenario
• Vessel or dealer report for trip—Vessel report missing
—Dealer report missing
• Ancillary information about a trip—Trip hails
—VMS declaration
—Dockside monitor report
11
Possible Resolutions
• Dealer and VTR data are available—Assign all dealer groundfish landings to statistical area
based on the statistical area reported on the VTR.
• Dealer data only, no vessel data—Apply landings to all stocks for which a sector has ACE
• VTR data only, no dealer data—Use the VTR landings by statistical area until dealer
data become available. Apply hail weight correction to account for anticipated underestimation of VTR hail weights relative to dealer weights.
12
Possible Resolutions
• No vessel or dealer information, but ancillary evidence of a groundfish trip—Apply the maximum trip-level groundfish landings by
that vessel for all groundfish stocks for which the sector has ACE. If no landings by that vessel to date apply the maximum trip-level landings across all sector vessels for which the sector has ACE.
