Catch reporting

Catch reporting is a part of Monitoring control and surveillance of Commercial fishing. Depending on national and local fisheries management practices, catch reports may reveal illegal fishing practices, or simply indicate that a given area is being overfished.

Manual Catch Reporting

The general industry practice is to write out a catch report on paper, and present it to a fisheries management official when they return to port. If information does not seem plausible to the official, the report may be verified by physical inspection of the catch. Alternatively, a suspicious vessel may need to carry an independent observer on future voyages.

Semi-automated Catch Reporting

Some Vessel monitoring systems have features that collect, from keyboard input, the data that constitutes a catch report for the entire voyage. More advanced systems periodically transmit the current catch as electronic mail, so fisheries management centers can determine if a controlled area needs to be closed to further fishing.

While there is no standardization as yet for catch reports, a starting point came from an 1981 Conference of Experts:

  • Catch on entry to each controlled area
  • Weekly catch
  • Transshipment
  • Port of landing
  • Catch on exiting a controlled area
  • Days at sea
  • Daily time at sea
  • Seasonal catch limits
  • Per-trip catch limits
  • Limits on catch within certain areas
  • Individual (vessel) transferable quotas
  • Minimum or maximum fish (or shellfish) sizes
  • This was extended, in 1993, to include: to include the measurement of:

  • catch
  • species composition
  • fishing effort
  • Bycatch (i.e., species unintentionally caught, such as dolphins in tuna fishery)
  • area of operations
  • A number of programs require tracking of days at sea (DAS) for a given vessel. They may require tracking the total cumulative catch of a given fishery.

    Major Trends

    Where the local fishery economy permits, perhaps with international funding, near-real-time catch reporting will become a basic feature of vessel management systems. Software at fisheries management centers will cross-correlate VMS position information, catch reports, and spot inspection reports.
