WCPFC Tuna Fishery Yearbook 2014
Monday, 19 October 2015 11:50

The WCPFC Tuna Fishery Yearbook 2014 has been released. It presents annual catch estimates in the WCPFC Statistical Area from 1950 to 2014.

The tables of catch statistics cover the main commercial tuna and billfish species caught in the region: albacore(Thunnus alalunga), bigeye (Thunnus obesus), skipjack (Katsuwonus pelamis), yellowfin(Thunnus albacares), black marlin (Makaira indica), blue marlin (Makaira nigricans), striped marlin(Tetrapturus audax) and swordfish (Xiphias gladius). The WCFPC, through their member countries, are now obliged to compile estimates of key shark species, some of which are now covered in the longline fleet tables: blue shark (Prionace glauca), silky shark (Carcharhinus falciformis), oceanic whitetip shark(Carcharhinus longimanus) and mako sharks (Isurus spp.).

The PDF edition is now available for download, as well as the associated Excel files. You can also query the Yearbook data through an online interface, available after a quick registration.

Identifying FAD-fishing
Tuesday, 25 August 2015 08:54

stevenh2015_08_25-sp_brailleTuna purse-seine catches associated with Fish Aggregation Devices (FADs) are typically more diverse than catches set on “free school” tuna, including both smaller target tuna as well a variety of bycatch species that are often discarded.  In response, an annual FAD-fishing moratorium, of several months’ duration and Pacific-wide, has been implemented since 2009.  Despite the moratorium, there remains concern about adherence to FAD-free fishing requirements.  Additionally, seafood producers and consumers seek certification regarding the source of purse seine captured tuna.

Given this background, we became interested in developing a FAD-association verification test.  We have developed a simple technique, based on observer catch sampling, to determine whether a purse seine set is likely to have been associated with a FAD.  Our methodology, which can be easily implemented “in the field”, has a prediction accuracy rate of up to 86%.  Details of the methodology have been published, in Open Access format, in the journal Fisheries Research.

2015 Tuna Stock Assessment Workshop
Wednesday, 17 June 2015 10:37

saw_2015_2 OFP is conducting a week-long Stock Assessment Workshop at SPC headquarters in Noumea from 22 to 27 June 2015.  A total of 26 regional scientists, representing 15 South Pacific countries as well as observers from the Forum Fisheries Agency and University of the South Pacific will participate.  The workshop will be led by OFP’s two National Scientists, Dr. Stephen Brouwer and Dr. Steven Hare.

Four years of data to enhance our knowledge on bigeye tuna
Thursday, 16 October 2014 14:21

FishPredominantly west-to-east movements and geographical concentration – the Equatorial Pacific bigeye tuna’s behaviour is gradually revealing its secrets. This and other findings have been reported in a new scientific paper authored by scientists from SPC and the Inter-American Tropical Tuna Commission, published recently in the journal Fisheries Research.

Tuna tissue bank for ecosystem management in the Pacific
Friday, 10 October 2014 12:09

FishSince 2001, SPC’s Oceanic Fisheries Programme (OFP) has been coordinating the collection of biological samples of pelagic species from all over the Pacific Islands region on behalf of its member countries.

Initially, this collection was focussed on stomach, muscle and liver samples to understand the trophic structure of the pelagic ecosystem (i.e. who eats who, where, and when); however, this has expanded to include gonads (reproductive organs), otoliths (ear bones), spines and blood, giving the opportunity to study reproduction, age, growth and contaminant concentrations.

The best way to protect heavily depleted shark populations? Stop trying to catch them!
Friday, 12 September 2014 15:01

It was previously thought that the two heavily depleted pelagic sharks in the Western and Central Pacific, the silky and the oceanic whitetip, were victims of unintended bycatch, but a startling new study from the Secretariat of the Pacific Community (SPC) shows that sharks are actually being specifically targeted by some tuna longline boats operating in the equatorial Pacific Ocean.

SPC Fisheries Newsletter #146
Tuesday, 16 October 2012 15:07

In the Pacific Island region, it is estimated that: 1) coastal fisheries resources provide the primary or secondary source of income for up to 50 per cent of households and 50–90 per cent of the animal-sourced protein consumed; 2) most coastal fish and invertebrate resources – at least all those accessible to coastal communities – are over-exploited or exploited to their limits; and 3) the population of many Pacific Island countries is growing rapidly and consequently the need for proteins is also growing.

There are a few alternative sources of protein: a bigger share of the offshore catch (primarily tuna) by industrial fleets could be reserved for local populations, and production from agriculture and livestock could probably be further developed, at least in high islands. But if coastal fisheries keep declining, these sources will not fill the gap, and they will not make up for the loss of income that coastal fisheries provide to communities.

Purse-seine fish ID cards for Pacific Islands Regional Fisheries Observers (PIRFO)
Thursday, 18 December 2014 10:33

These identification cards have been produced to help with the identification of fish species encountered by Fisheries Observers while onboard commercial tuna purse seiners that fish in the Western and Central Pacific Ocean (WCPO). The species included in these cards are the ones commonly recorded by observers on tuna purse seine vessels operating in the WCPO. The cards can be easily accessed by observers while working on deck during net hauling and brailing operations to verify and correctly identify fish species. The cards also assist in training observers operating within the Western and Central Pacific Fisheries Commission Convention Area.

CP10 tagging cruise collaborates with ISSF and industry to do research on drifting fads
Friday, 10 October 2014 16:25

FishIn last August 2014, SPC fisheries scientist Bruno Leroy was in charge for this 25 day cruise that drove the Tongan FV Pacific Sunrise through the waters of American Samoa, Tokelau, Cook Islands and Kiribati-Phoenix Islands. The Central Pacific (CP) tuna tagging cruises were originally designed to tag tuna in areas where pole and line boats could not really work due to the scarcity of live baits and also to increase the releases of tagged bigeye tuna that are rarely caught in the surface fisheries in the western part of the Pacific.

New fish species discovered in the waters of New Caledonia

FishWhile on a boat not far from Toombo Reef near Boulari Pass on 11 August 2014, Pierre and William Larue found a small silvery fish floating on the water.

The fish was first given to the IRD (French Institute of Research for Development) and then SPC took over the task of identifying this small hatchetfish from the Sternoptychidae family.

Condition of bigeye tuna in the western and central Pacific worsening, skipjack and yellowfin healthy – new SPC assessments released
Friday, 25 July 2014 15:48

johnh2014_07_25_thumbFriday 25 July 2014, Secretariat of the Pacific Community (SPC) headquarters, Noumea, New Caledonia

The Secretariat of the Pacific Community (SPC) this week released new assessments on the status of key regional tuna stocks – skipjack, yellowfin and bigeye tuna – which show that skipjack and yellowfin remain in a reasonably healthy state, but bigeye, the mainstay of the tropical longline fishery, has now been reduced to less than 20% of its unfished stock size. The assessments, along with over 40 scientific papers produced by SPC, are due to be presented at the 10th meeting of the Western and Central Pacific Fisheries Commission (WCPFC) Scientific Committee, being held in Majuro, Marshall Islands, in early August.
