Fish aggregating devices, or FADs, are used widely in developing countries to concentrate pelagic fish, making them easier to catch. Nearshore FADs anchored close to the coast allow access for rural communities, but despite their popularity among policy makers, there is a dearth of empirical analysis of their contributions to the supply of fish and to fisheries management. In this paper we demonstrate that nearshore FADs increased the supply of fish to four communities in Solomon Islands. Estimated total annual fish catch ranged from 4300 to 12,000 kg across the study villages, with nearshore FADs contributing up to 45% of the catch. While it is clear that FADs increased the supply of fish, FAD catch rates were not consistently higher than other fishing grounds. Villages with limited access to diverse or productive fishing grounds seemingly utilized FADs to better effect. Villagers believed FADs increased household income and nutrition, as well as providing a source of fish for community events. FADs were also perceived to increase intra-household conflict and reduce fishers' participation in community activities. FADs need to be placed within a broader rural development context and treated as another component in the diversified livelihoods of rural people; as with other livelihood options they bring trade-offs and risks.
集鱼装置(FADs)在发展中国家被广泛用于聚集中上层鱼类,使其更易于捕捞。靠近海岸锚定的近岸集鱼装置方便农村社区使用,但尽管它们在政策制定者中很受欢迎,却缺乏关于其对鱼类供应和渔业管理贡献的实证分析。在本文中,我们证明近岸集鱼装置增加了所罗门群岛四个社区的鱼类供应。整个研究村庄的年鱼类捕捞总量估计在4300至12000千克之间,近岸集鱼装置的捕捞量占比高达45%。虽然集鱼装置显然增加了鱼类供应,但其捕捞率并不总是高于其他渔场。进入多样化或高产渔场机会有限的村庄似乎能更好地利用集鱼装置。村民们认为集鱼装置增加了家庭收入和营养,也为社区活动提供了鱼类来源。集鱼装置还被认为加剧了家庭内部冲突,并减少了渔民对社区活动的参与。集鱼装置需要置于更广泛的农村发展背景中,并被视为农村居民多样化生计的另一个组成部分;与其他生计选择一样,它们带来了权衡和风险。
