Fish-aggregating devices (FADs) have been used in centuries to attract fish and facilitate their captures. Drifting FADs developed at a large and industrial scale, but moored fish-aggregating devices (MFADs) are mostly used by artisanal fishers and often implemented to shift the pressure away from depleted coastal fish stocks and toward large migratory pelagic fish populations. Indeed, as pelagic fish aggregate around the devices, MFADs allow small-scale fishers to access this resource and improve their income. If there are many studies on the development of MFADs, the underlying assumption that the development of the MFAD fishery leads to the redeployment of the coastal fleet toward large pelagic species remains unproven. In the French archipelago of Guadeloupe, Lesser Antilles (FAO area 31), an important small-scale MFADs fleet targeting dolphinfish and tuna species developed since the end of the 80s. Available data on vessels, fishers and fishing effort permitted to develop a stock-flow framework and to analyse allocation of fishing effort between coastal and MFADs fisheries over the 2008–2019 period as well as the fleet and sub-fleet dynamics. The framework showed that the redeployment of fishing effort towards pelagic species thanks to MFADs was not straight forward. Pelagic vessels were more likely to become coastal than the opposite, and there was no influence of MFADs on the likelihood of pelagic vessels to quit their coastal activity. Instead, vessels fishing both on MFADs and coastal stocks were the dominant sub-fleet in the pelagic fleet in 2019. Nevertheless, pelagic vessels fished less and less on coastal stocks during the period, which was correlated with an increased use of MFAD. It also showed that the MFAD fishery remained more attractive for younger fishers but, as for the coastal fishery, MFADs failed to attract enough newcomers to compensate the outflows of ageing fishers as working conditions and barriers to enter the fishery remain key issues.

几个世纪以来，集鱼装置 (FAD) 一直被用来吸引鱼类并促进捕获。漂流 FAD 已大规模工业化发展，但系泊鱼类聚集装置 (MFAD) 主要由手工渔民使用，通常用于将压力从枯竭的沿海鱼类种群转移到大型洄游中上层鱼类种群。事实上，随着远洋鱼类聚集在这些设备周围，MFAD 允许小规模渔民获取这种资源并提高他们的收入。尽管对 MFAD 的发展有很多研究，但关于 MFAD 渔业的发展导致沿海船队重新部署到大型中上层物种的基本假设仍未得到证实。在法属瓜德罗普岛、小安的列斯群岛（粮农组织 31 区），自 80 年代末以来，一支重要的小规模 MFAD 船队以海豚鱼和金枪鱼物种为目标发展起来。有关船只、渔民和捕捞努力量的现有数据有助于制定种群流量框架，并分析 2008-2019 年期间沿海渔业和 MFAD 渔业之间捕捞努力量的分配以及船队和子船队动态。该框架表明，通过 MFAD 将捕捞努力重新部署到中上层物种并不是一帆风顺的。远洋船只比相反的更有可能进入沿海，并且 MFAD 对远洋船只退出沿海活动的可能性没有影响。相反，在 MFAD 和沿海种群上捕捞的船只是 2019 年远洋船队中的主要子船队。尽管如此，在此期间，远洋船只对沿海种群的捕捞量越来越少，这与 MFAD 使用的增加有关。它还表明，MFAD渔业对年轻渔民仍然更具吸引力，但就沿海渔业而言，MFAD未能吸引足够的新来者来补偿老龄渔民的外流，因为工作条件和进入渔业的障碍仍然是关键问题。
