brouwer_16_western_tuna_2015_overviewTuna fisheries assessment reports provide most recent information on the tuna fisheries of the western and central Pacific Ocean and the fish stocks (mainly tuna) that are impacted by them. The information provided a summary, but a list of references (mostly accessible via the Internet) is included for those seeking further details.

This report focuses on the main tuna stocks targeted by the fisheries - skipjack tuna (Katsuwonus pelamis), yellowfin tuna (Thunnus albacares), bigeye tuna (T. obesus) and South Pacific albacore tuna (T. alalunga).

Whales, dolphins and sea birds ID cards for Pacific Islands Regional Fisheries Observers
Wednesday, 11 May 2016 10:50

These identification cards were produced to help with the identification of species of special interest (protected species) encountered by fisheries observers while onboard commercial tuna fishing vessels. Observers collect information about sightings of these species and about interactions between these species and fishing activity and/or fishing gear. Regional requirements are in place for observers to report on interactions of fishing activities with species of special interest and on mitigation methods employed by the vessel to reduce the likelihood of these associations and the possible impacts on the animals, such as injuries.

Snapper Harvest Strategy
Wednesday, 10 February 2016 13:48

Deepwater snapper are an important resource for many Pacific island countries and territories (PICTs). Fisheries for deepwater snapper supply domestic and export markets, acting as both a food source and economic commodity. However, a lack of formalised harvest policies for deepwater snapper stocks has resulted in ad-hoc management in many countries.

This fact sheet outlines three alternative stock assessment techniques for deepwater snapper fisheries and examples of their incorporation into a formal harvest strategy.

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 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.  The long-term purpose of these workshops – which have been run since 2006 – is to increase regional fisheries officers ability to: understand and interpret the results from the regional oceanic fisheries stock assessments; communicate this information to fishery managers within their countries; and increase their confidence to participate in scientific discussions of the Western and Central Pacific Fisheries Commission (WCPFC), in particular during meetings of its Scientific Committee.  The workshop will feature presentations from several OFP scientists and material presented in lectures will be covered in daily practicals where participants will learn to conduct basic stock assessment analyses using models developed in Excel spreadsheets.

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.

Fish

Tuesday, 2 September 2014

While 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.
