Pacific Tuna Tagging
Wednesday, 13 October 2010 08:15

The Secretariat of the Pacific Community (SPC) is currently conducting a region-wide tuna tagging project to collect critical information for the assessment of these important resources.

Tagging consists of catching tunas and deploying conventional (plastic dart tags inserted into the dorsal musculature) or electronic tags (surgically implanted into the body cavity) before releasing them in the wild. When fishermen find a tagged tuna, information concerning the recovery is forwarded to SPC.

The specific objectives of this research are to obtain information on the growth, movements, natural mortality and fishing mortality of the tuna, information·which is required to estimate the status of the stocks and the impacts of fishing.

The Shark TAGging Information System (STAGIS)
Tuesday, 05 July 2011 11:18

Carcharhinus longimanusSPC-OFP is very pleased to announce the launching of STAGIS the Shark TAGging Information System, which is now hosted on the SPC-OFP website for free public access. It can be accessed at http://www.spc.int/ofp/shark/.

This database was populated through the contributions of numerous shark researchers, who gave generously of their information and time to support this effort, as well as through a literature review conducted by SPC-OFP.

Bycatch Management Information System (BMIS)
Friday, 29 April 2011 11:07


The Bycatch Management Information System (BMIS) focuses on bycatch mitigation and management in oceanic tuna and billfish fisheries*. It is an open resource useful for fishery managers, fishers, scientists, observers, educators and anyone with an interest in fisheries management. As a reference and educational tool, the BMIS aims to support the adoption and implementation of science-based management measures so that bycatch is managed comprehensively and sustainably.

Spatial Ecosystem and Population Dynamics Model (Seapodym)
Wednesday, 26 August 2009 14:56

altAssessment of the historical, present and future states of marine ecosystem and the effects of human exploitation and climate variation have on the state of ecosystems are necessary to implement an ecosystem-based fishery management system. In particular, understanding how tuna, tuna-like populations and by-catch species respond to environment variation and anthropogenic changes (fishing pressure) is a major challenge for developing this approach. Modeling should be focused on comprehending the mechanisms linking the biological and physical components of marine ecosystems and exploring the responses of populations at higher trophic levels to different types of physical forcing, biological interactions, exploitation and they potential synergies.

Fiji National Tuna Data Workshop : Good data = Good decisions - Fiji
Tuesday, 08 November 2011 09:12

Collecting and managing information is the core task for the majority of staff employed in Pacific Island Fishery government agencies. The tuna data they collect provides a clear picture of the fishery, a solid basis for management decisions and offers an appreciation of historical fishing patterns.  To support this work, SPC has run a series of regional workshops aimed at sharing the best practices for gathering and preparing tuna data, which are subsequently used in the management of the tuna fishery in the western and central Pacific (see http://www.spc.int/oceanfish/en/meetingsworkshops/tdw).   To convey the message even further and facilitate the implementation at the country level, a series of national data workshops have also been undertaken since the start of 2010.

6th Annual Tuna Stock Assessment Workshops
Friday, 22 July 2011 14:03

sawA record number of participants attended this year’s annual stock assessment workshops hosted by the Secretariat of the Pacific Community’s Oceanic Fisheries Programme (SPC-OFP). A total of 30 participants from 23 Pacific countries attended the workshops which are now recognised as an important program in capacity building for fisheries officers and managers in the region. This year, for the first time, participants were introduced to the Tuna Management Simulator (TUMAS) a new software tool developed by the OFP that allows fishery managers and advisors to evaluate the performance of different management options.  TUMAS allows commission members to explore and compare the results of different management options and assists them to make management decisions and negotiate at regional fisheries meetings.

Tuna Fisheries of the Western and Central Pacific Ocean
Monday, 19 July 2010 08:04


Tuna fishing in the Pacific Islands region has a rich history. For centuries, tuna have provided an important source of food for Pacific Island peoples and the traditional fishing techniques and equipment involved are part of their cultural heritage. Today, tuna are also an important source of income and employment for many SPC island members. For some, the tuna resources within their 200 mile exclusive economic zones (EEZs) represent their only significant renewable resource and their best opportunity for economic development.

The fishery in the Western and Central Pacific Ocean is therefore diverse, ranging from small-scale artisanal operations in the coastal waters of Pacific states, to large-scale, industrial purse-seine, pole-and-line and longline operations in both the exclusive economic zones of Pacific states and on the high seas. The main species targeted by these fisheries are skipjack tuna (Katsuwonus pelamis), yellowfin tuna (Thunnus albacares), bigeye tuna (T. obesus) and albacore tuna (T. alalunga). Artisanal and larger-scale commercial fisheries exploiting the same stocks of these species also occur in the Pacific Ocean waters of adjacent southeast Asian countries, particularly Indonesia, Philippines and Vietnam.

New research plan provides a blueprint for addressing shark issues in the western and central Pacific
Wednesday, 27 October 2010 08:14

What should be done about sharks? Heavy fishing pressure is believed to be threatening some shark populations. The Western and Central Pacific Fisheries Commission (WCPFC) has taken a major step toward addressing concerns about shark populations with initial approval of a three-year Shark Research Plan by its Scientific Committee (see Useful Shark Links, #1). The plan will be led by the Oceanic Fisheries Programme of the Secretariat of the Pacific Community, and will contain assessment, research coordination and fishery statistics improvement components. The overall aim of the plan is to evaluate the status of blue, mako, oceanic whitetip, silky and thresher sharks in the western and central Pacific Ocean (WCPO) and to establish better datasets to support future assessments.  Following its recent endorsement by the Scientific Committee, the Shark Research Plan will be presented for full Commission approval at its annual meeting in Hawaii in December.


This article outlines the background and context of shark issues in the WCPO, introduces the key species and previews the forthcoming assessment work.
