Conference Paper
Full-text available
The WCPFC Bycatch Management Information System (BMIS) is an online resource for fisheries managers, scientists, fishers, educators and the public (see Figure 1). The database consolidates information on the mitigation and management of species of special interest, including seabirds, sharks and rays, marine turtles and marine mammals, incidentally...
Conference Paper
Full-text available
The Western and Central Pacific Fisheries Commission (WCPFC) has a responsibility to assess the impact of fishing on non-target species. In this report, we estimate the bycatch of the large-scale purse seine fishery operating primarily in tropical waters of the WCPFC Area east of 140°E. These large vessels, typically greater than 500 tonnes carryin...
Conference Paper
Full-text available
A comprehensive overview of the redevelopment of the Western and Central Pacific Fisheries Commission (WCPFC) Bycatch Management Information System (BMIS) 1 was tabled at the 2017 Scientific Committee meeting (Fitzsimmons et al., 2017). The work under the final year of funding from the FAO Common Oceans (Areas Beyond National Jurisdiction - ABNJ) T...
Conference Paper
Full-text available
This report summarises progress on the Project 60 work plan as endorsed by the 2017 Scientific Committee. The main activities undertaken since SC13 were: updating the availability model currently used to correct grab sample bias; updating a simple multinomial model initially proposed during external reviews of Project 60 in 2012; negotiations to re...

Conference Paper
Full-text available
WCPFC has responsibilities in: assessing the impact of fishing and environmental factors on non-target species and species belonging to the same ecosystem or dependent upon or associated with the target stocks; to minimize catch of non-target species; to protect biodiversity; and, to adopt, when necessary, conservation and management measures for n...
Preprint
Full-text available
Long-term collection of data and samples appears critical to contribute to our understanding of the impacts of fisheries and climate change on the marine ecosystems, and for the implementation of management measures for sustainable use of the resources. In the western and central Pacific Ocean, the source of 50% of the worldwide tuna catches, sever...

Conference Paper
Full-text available
The WCPFC Bycatch Management Information System (BMIS) has been redeveloped as a global resource with funding provided by the FAO Common Oceans (Areas Beyond National Jurisdiction -ABNJ) Tuna Project. The new BMIS offers a broader range of curated material, retaining an emphasis on mitigation techniques and their efficacy, while expanding managemen...
Conference Paper
In 2017 the Pacific Community and the Japanese National Research Institute of Far Seas Fisheries collaborated on analyses of Japanese purse seine vessels catch data. The analyses focused on the estimation and comparison of species and size compositions of purse seine catches based on a variety of data sources. This collaborative effort is an input...
Conference Paper
Full-text available
This report documents the construction of the tagging files used in the 2016 skipjack stock assessment in the western and central Pacific Ocean. Methods closely follow those used by Berger et al. (2014) with several improvements made to the construction process, particularly simplifying and generalizing the process and code. The procedure for produ...
Article
Full-text available
8217 days of data downloaded from 47 archival tags, recovered from bigeye tuna (Thunnus obesus) 51-134 cm in length (x-=86.9cm), 0.87-3.44 years of age (x-=1.89years) at liberty from 36 to 851 days (x-=183days) in the equatorial central Pacific Ocean, are evaluated herein. Analyses of depth and temperature records resulted in the classification of...
Conference Paper
Full-text available
The Bycatch Management (formerly ‘Mitigation’) Information System (BMIS) is being redeveloped as a global resource with funding provided by the ABNJ (Common Oceans) Tuna Project. It is proposed that the new look BMIS will present a broader range of material, particularly regarding the management of bycatch, e.g., bycatch species interaction rates a...
Article
A total of 31,242 bigeye tuna was captured, tagged, and released, 30,793 with dart tags (DTs) and 449 with geolocating archival tags (ATs), in the equatorial central Pacific Ocean along the 140° W, 155° W, 170° W, and 180° meridians, during 2008 through 2012, of which 10,029 (32.1%) of the DTs and 74 (16.5%) of the ATs were returned. A subset of hi...
Article
Full-text available
In the Western and Central Pacific Ocean (WCPO), which accounts for over half of world tuna production, purse seine effort and catch on floating objects have increased significantly due to a rapid increase in the use of fixed and free-floating fish aggregation devices (FADs). FAD fishing has had an impact on the current status of the stocks of the...

Article
Full-text available
The Western and Central Pacific Ocean sustains the highest tuna production in the world. This province is also characterized by many islands and a complex bathymetry that induces specific current circulation patterns with the potential to create a high degree of interaction between coastal and oceanic ecosystems. Based on a large dataset of oceanic...

Project
The BIOPELAGOS project aims at supporting the Pacific French territories of New Caledonia and Wallis and Futuna to make informed decisions for the sustainable management and the conservation of their oceanic biodiversity and ecosystems through: • acquiring new knowledge on oceanic biodiversity and functioning of the ecosystem (scientific cruises and seabird surveys) • capacity building (students, information to the public); • provision of scientific advices and recommendations to support decision on conservation, sustainable management and resilience of oceanic ecosystem. http://www.spc.int/oceanfish/ofpsection/ema/biopelagos
