Fact sheets

  • Summary of Preliminary Results of Transboundary Diagnostic Analysis (TDA), 2018, four pages, WCPO Fisheries Management
    Tuna are highly mobile species that can move large distances. Tuna fisheries are not contained within one country’s exclusive economic zone (EEZ) and will move through many EEZs as well as the high seas. This makes tuna fisheries a “transboundary problem”. This fact sheet describes a diagnostic analysis of this transboundary problem. The link to the complete report is below under “Technical papers”.

Country web page reports: Bycatch

The Pacific Community (SPC) hosts a Member Countries Tuna Fisheries web site. It gives individual countries information on aspects of their fisheries. Reports on bycatch are a great example of the SPC reports produced specifically for each country. Once Pacific countries have this information, they are in a stronger position to negotiate a better deal with fishing fleets. Pacific Island countries and territories (PICTs) use their own password to access their country’s confidential data and reports. Those who need a login and password can get it from Emmanual Schneiter at SPC.

Each confidential country web page includes data and graphs that are updated 4 times a year. The main groups of data included on country pages are listed here.

  • Catch by species (of target tuna):
    – summarised by gear type and by flag
    – national fleet catch summarised inside and outside EEZ.
  • 2. Catch by gear type:
    – summarised by species and by flag
    – national fleet catch summarised inside and outside EEZ.
  • Catch per unit effort:
    – summarised by gear type and flag
    – purse-seine catch summarised by FAD association
    – spatial plots of effort and catch by 5° and 1° latitude/longitude squares.
  • Biological data for target tuna species (just length frequencies currently)
  • Gear characteristics (e.g. hooks per set for longlines, set start times for purse seines)
  • Observer collected data (longline vessels only):
    – observer coverage
    – observed CPUE (catch per unit of effort) of target and bycatch species
    – list of all bycatch species and fate of key species

The country web pages are particularly useful for helping each country to produce a Part 1 Report that summarises their historical fishing activities within their EEZ. This report is required annually for inclusion to data summaries at the annual WCPFC Scientific Committee meeting.

SPC researcher Steven Hare explains (57 secs).

Regional networks

  • Pacific Community Centre for Ocean Science (PCCOS), which aims to help Pacific Island governments and communities easily access the ocean science and expertise they need so they can make informed decisions so that they can protect and sustainably manage ocean resources
  • Pacific Data Hub, a repository of open data and knowledge products about the Pacific region that is publicly available
