samLate 2013 saw the departures of Dr Tim Adams to warmer and more humid climes, Dr Simon Hoyle to cooler and less humid climes, and Dr Aaron Berger downstairs to a new post within the OFP analysing tagging data. It also saw approval of the New Zealand Scientific Support project, which provided the team a second national scientist position. So over the past couple of months we have been searching far and wide for people to join the team and we are pleased to announce three new additions to the Stock Assessment and Modelling team.

A scientific perspective on current challenges for PICT domestic tuna longline fleets that are dependent on south Pacific albacore
Wednesday, 12 February 2014 10:59

grahamP2014_02_12_thumbIn recent years domestic fishing fleets targeting primarily albacore in Pacific Island Countries and Territories (PICTs) have reported difficulties in maintaining profitability, and as noted in a PITIA press article, in the last few months many vessels based in Fiji have stopped fishing altogether and are tied up at wharves. The PITIA article notes that despite their experiences on the water, scientific stock assessments “continue to produce relatively healthy results”.

The purpose of this article is to summarise some of the recent scientific analyses of south Pacific albacore. It won’t discuss issues such as the prices of fish or fuel, or the mobility of fleets that enhances or constrains their ability to follow or find fish; clearly these issues would be expected to play a large role in the profitability of individual fleets.

Pacific Island Tuna Scientists in town
Monday, 01 July 2013 00:00

 

Fisheries scientists and technicians from most of the SPC island membership converged on Noumea this week to learn more about the way that SPC’s Oceanic Fisheries Programme is assessing their shared tuna stocks, and to suggest ways in which OFP outputs could be directed even more usefully in helping them to answer the questions asked by Pacific Island tuna fishery decision-makers.

Staff movements in the Stock Assessment and Modelling section
Thursday, 05 September 2013 15:07

samI arrived to be part of a team of five people in 2008, and that has grown to nine by 2013, but the nature of our project funding means that there are always changes in the team and 2013 has been no exception.

In January Dr Carola Kirchner joined the team from Namibia where she was the lead stock assessment scientist, to work supporting the needs of the Parties to the Nauru Agreement. This position has been funded through the Pew Charitable Trusts and the World Bank and over the two years of the project Carola will be driving the development of Harvest Control Rules (HCRs) and supporting the development of bioeconomic models for the purse seine fishery.

An improved version of the MULTIFAN-CL software
Wednesday, 29 February 2012 14:29

mutifan-clScientists at SPC have been using the MULTIFAN-CL software for over ten years to assess the status of tuna and tuna-related species in the Western and Central Pacific Ocean. SPC scientist Nick Davies, along with the chief developer Dave Fournier of Otter Research Limited, has just released an updated version of the software that allows for faster and more efficient analysis of management options. The model also has new features so that it can include 300,000+ tags released in SPC’s highly successful Pacific Tuna Tagging Programme.
