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”.

A summary of the Strategic Action Programme (SAP), a set of actions that will resolve or reduce the problems discussed in the TDA. The small island developing states (SIDS) will implement the SAP with the support of the Forum Fisheries Agency (FFA) and the Pacific Community (SPC). The link to the complete report is below.

- As part of OFMP2, FFA has produced a fact sheet on Climate change and Pacific tuna fisheries.Topics covered include:
1. Climate naturally affects the distribution and abundance of tuna
2. Climate change under continued high greenhouse gas emissions will change tuna habitats
3. Climate change reduces nutrients and food availability for tuna
4. Climate change affects the 4 species of tuna differently
5. Climate change will affect fishing catch and revenue, but there are options
6. Decline in coastal fisheries under climate change means tuna is vital for food security
7. Research modelling addressing knowledge gaps.

The authors examine methods of protecting ongoing supplies of tuna and other seafood for human consumption. They conclude that, for highly migratory species such as tuna, protecting their environment is not sufficient: fisheries also need to be better managed. There are many ways to do this, including using remote-sensing devices to track tuna and fishers. Combining protected areas, for example by joining them with corridors that are also protected, would also help protect stocks. - Global ensemble projections reveal trophic amplification of ocean biomass declines with climate change, Heike K.

This report fills an earlier gap in the management development process for the Pacific Islands Oceanic Fisheries. When the original Strategic Action Programme (SAP) was adopted in 1997, it was not based on a detailed TDA. This document is the result of a number of working groups and consultations, with specific inputs from many organisations. Much of the information was gathered from high-quality existing reports and publications, and examines the root causes of the problems discussed.
- Strategic Action Programme for the sustainable management of living oceanic resources by the small island developing states of the Western and Central Pacific, Oceanic Fisheries Management in the Pacific, draft for review, October 2018
The Strategic Action Programme (SAP) reviews the problems and concerns that were identified in the TDA. It identifies a set of clear priorities for action by the Pacific Island countries and territories, and their partners in the region, to resolve or minimise the problems identified. All ministers on the Forum Fisheries Committee, which governs the Forum Fisheries Agency (FFA), signed their country’s agreement with the SAP in June 2019. FFA announced the signing in a media release.

This publication provides a quick and general understanding of the status of fisheries and aquaculture in the Pacific Islands region. It is an update of the 2011 FAO publication, Fisheries of the Pacific Islands: Regional and national information. In addition to a regional overview, it provides fisheries and aquaculture profiles for the 14 independent Pacific Island countries, including chapters on:
1. General geographic and main fisheries economic indicators, including a summary of fisheries statistics reported to FAO
2. Production sectors
3. Post-harvest sectors
4. Socio-economic contribution of the fishery sector
5. Trends, issues and developments
6. Institutional framework
7. Legal framework. - This report is discussed in Franscisco Blaha’s blog, May 2018

Posters & videos

Marine biologist Valerie Allain describes the SPC’s largest collection of tuna tissue samples available to scientists for research on understanding tuna (3:50 mins).
Laurent Dagorn, a senior scientist with the French Research Institute for Development, describes the utility of FADs when they are not over-used. Video in English, produced by ISSF (3.39 mins).
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).
