Tuna Fishery Data Collection Logsheet data
Recorded by Vessel captain Fishing
company Unit of collection Data cover a
Vessel trip Coverage required 100 (i.e.
covering all activity) Latest form version DCC
2004 (all fisheries)
Main characteristics

• Effort and catch are reported at the fishing
  operation level
• Logsheet data collection cover the commercial,
  artisanal and recreational/sports fisheries
• The logsheet focuses on reporting the catch of
  target species and primary by-catch species
• The catch in weight recorded is usually a visual
  estimate
• Validated by Unloadings, Port Sampling and
  Observer data

10
Tuna Fishery Data Collection Unloadings data
Recorded by Fishing company / Agent for
unloadings Unit of collection Data represent
catch from a Vessel trip Coverage required
100 (i.e. covering all unloadings) Latest form
version DCC 2004
Main characteristics

• Provide the actual, measured weight of the catch
  (by species) from a vessel trip LONGLINE.
• Longline unloadings are a summary of the packing
  list, the reject list and the list of
  cannery-bound fish (e.g. albacore)
• Provide an independent estimate of the trip
  catch, which can be used to verify and correct
  the logsheet data.
• Can be validated by Logsheet, Port Sampling and
  Observer data

11
Tuna Fishery Data Collection Port Sampling data
Recorded by Fisheries staff (Port
samplers) Unit of collection Data represent
catch from a Vessel trip Coverage required 20
(recommended target coverage) Latest form
version DCC 2004
Main characteristics

• Offers a convenient, cost effective method to
  obtain considerable quantities of species and
  size composition data for stock assessment work
• Provides an independent verification of the data
  submitted by the fishing company (i.e. logsheets,
  unloadings data and packing/reject/cannery lists)
• Only partial coverage of port sampling data is
  required (Target 20 - randomly-selected
  unloadings)
• The entire unloaded catch from a trip must be
  sampled, or accounted for

  species, and the effort expended than any other
  data source
• Provides the only reliable means to determine the
  extent of non-target catch and discards in the
  fishery
• Provides the only means of verifying catch and
  effort data recorded on logsheets at the fishing
  operation level
• Vessel and Gear Details
• Provides an opportunity for biological sampling
• Both Compliance and Scientific Aspects

• Summary list of vessel trips and periods in port
  during the calendar year
• Specifically checks the periods when vessels are
  in-port throughout the calendar year

forms reqd. electronically received)
Main characteristics

• Provides highly accurate information on the
  position of vessel, often at intervals of very
  short time periods (e.g. every 4 minutes?)

19
Types and functions of data

• 3.1 EXERCISE SESSION
• Group Discussion Think about the data
  collection in your country (Share experiences
  on each type of data collected). Are there any
  other types of data collected in your country not
  mentioned here ?
• Exercise (Individual countries) You will be
  provided handouts/exercises designed to
• Test your knowledge on two types of Data
  Collection (logsheets and unloadings), and
• Prompt you with questions to provide specific
  information on these data collection systems in
  your country
• You can start completing the questions in these
  exercises now, but there will be some questions
  that might be better attempted after covering the
  material in subsequent sessions The output will
  be incorporated into your National Procedures
  document.
• If you have time later you can continue this
  exercise for other types of data collected in
  your country.
