Résumé : Over the last 16 years, the Secretariat of the Pacific Community (SPC - formerly the South Pacific Commission) has been developing and providing information on mid-water fishing techniques targeting the larger, deeper-swimming tunas that aggregate around FADs. SPC masterfishermen have conducted in-country fishing trials to test methods, such as vertical longlines, and train local fishermen in their construction and use. Vertical longline catch rates have varied considerably due to a range of reasons with no catches reported in some locations, or just sharks, to highs of over 6.5 kg /10 hooks/hour being recorded in other locations. Other methods like drop-stone, palu-ahi, and single-hook drifting lines have been developed within the region, with SPC adopting and transferring this technology to other locations. To further disseminate this information, SPC has recently published a technical manual outlining a range of mid-water fishing gears and techniques that can be used in association with FADs. An outline of the main gears and techniques with catch data where available is presented, with factors influencing catches discussed based on the findings of SPC masterfishermen over the years.

Résumé : Since the early 1980's, the Secretariat of the Pacific Community (SPC, formerly the South Pacific Commission) has contributed to the development of FAD programmes for the artisanal fisheries sector in the Pacific region. In particular, it has put considerable efforts into developing technology that would assure a two-year average FAD lifespan, while maintaining costs under US$ 4,000 per FAD unit. From 1996 to 1998, this work led to the publication of three volumes of the SPC FAD Manual. Volume 2 of this manual, "Rigging Deep-Water FAD Moorings", describes in great detail two FAD models that were developed from the original 1983 SPC-recommended model, and gives precise instructions on the way to construct them. Despite SPC's work, the objectives set, in particular the two-year average lifespan for FADs, have not been consistently met, resulting in many FAD programmes in the region being suspended. An analysis of the reasons why this has occurred is presented, along with a short description of the practical research that could be pursued, using different objectives, to introduce new FAD programmes in the region.Original Abstract: Depuis le debut des annees quatre-vingt, le secretariat general de la communaute du Pacifique (SPC, anciennement commission du Pacifique Sud) a soutenu et accompagne le developpement de programmes DCP destines au secteur de la peche artisanale, dans la region Pacifique. Il s'est en particulier efforce de mettre au point des modeles de DCP repondant principalement aux deux criteres suivants: duree de vie superieure a deux ans et cout unitaire moyen inferieur a 4 000 dollars US. Entre 1996 et 1998, ces travaux ont abouti a la publication en trois volumes du manuel de la SPC sur les DCP. Le volume 2 de ce manuel, " La fabrication de DCP pour grandes profondeurs ", presente deux evolutions d'un modele concu en 1983 et en detaille tres precisement les methodes de fabrication. Le present document analyse les raisons pour lesquelles, malgre les efforts deployes, les objectifs fixes, et en particulier la duree de vie minimum de deux ans pour les DCP, n'ont pas ete pleinement atteints et la plupart des programmes DCP de la region ont ete interrompus. Il donne egalement une breve description des axes de recherche appliquee qui pourraient etre suivis, en se fixant d'autres objectifs, pour relancer des programmes DCP dans la region.

Résumé : In the area served by the Secretariat of the Pacific Community (SPC), which includes 22 Pacific Island countries and territories, anchored FADs have been used since the late 1970s. First introduced from the Philippines, via Hawaii, they were quickly adopted by both industrial and artisanal fisheries sectors : in 1984 more than 600 anchored FADs had been deployed in the region. Since these early days, the development of the technique by the industrial and the artisanal sectors have followed parallel paths with little interaction. In the industrial private sector, companies are funding, deploying and monitoring their own FADs. For some fishing companies, using purse seiners and pole-and-line vessels, from the Solomon Islands or Papua-New-Guinea, these FADs have become a necessity. FAD programmes for small-scale fisheries have been almost exclusively run by the public sector, with technical support from regional and international development agencies and financial assistance from overseas funding agencies. These programmes have had mixed successes : becoming an on-going and essential tool in some places like French Polynesia or Guam; or being momentarily suspended, like in Vanuatu or Tonga, because of the lack of funds, partly due to the scarcity of proven economic return to the fishing communities. This document is an attempt to synthesise the current information on these very diverse situations, including technical, economical and social considerations.
