Small‐scale driftnets (SSDs) have been historically used in the Mediterranean without major environmental concern. The introduction of large‐scale driftnets caused unwanted catches of protected species. Specific regulations were therefore issued in European waters, culminating in a proposed moratorium on SSDs. This study aimed to characterise the SSD fishery targeting anchovy (menaide), evaluating its environmental sustainability, economic performance and social relevance. In 2013, a survey by interviews, logbooks and observers on board assessed the order of magnitude of this fishery in terms of fishing capacity and activity, volume of landings and revenues. The menaide fleet consisted in 60 vessels <12 m overall length, moored in little harbours in southern Italy. These nets are highly selective: the target species, European anchovy, Engraulis encrasicholus (L.) and sardine, Sardina pilchardus (Walbaum), dominates the catches, while discards are negligible. The anchovies caught are of high quality and large size; the high prices support fish processing by local factories. Moreover, the results of a SWOT analysis demonstrated that replacing SSDs with a semi‐industrial fishery, like purse seining, would increase impacts on the ecosystem, and a loss of socio‐economic opportunities for several coastal villages. These findings support the option of keeping SSDs operating, in the framework of specifically oriented management measures.

一种选择性的、低影响的传统渔业，维持地中海中部沿海小村庄的经济：保留还是更换小规模流网？

小规模流网（SSD）历来在地中海使用，没有重大的环境问题。大规模流网的引入导致了对受保护物种的不必要的捕获。因此，在欧洲水域颁布了具体法规，最终提议暂停使用 SSD。本研究旨在表征以鳀鱼（menaide）为目标的 SSD 渔业，评估其环境可持续性、经济绩效和社会相关性。2013 年，通过访谈、航海日志和船上观察员进行的一项调查评估了该渔业在捕捞能力和活动、上岸量和收入方面的数量级。Menaide 舰队由 60 艘船组成，总长度小于 12 m，停泊在意大利南部的小港口。这些网是高度选择性的：目标物种，欧洲凤尾鱼，Engraulis encrasicholus (L.) 和沙丁鱼 Sardina pilchardus (Walbaum) 占主导地位，而丢弃物可忽略不计。捕获的凤尾鱼质量上乘，个头大；高价格支持当地工厂进行鱼类加工。此外，SWOT 分析的结果表明，用围网等半工业渔业取代 SSD 会增加对生态系统的影响，并会导致几个沿海村庄失去社会经济机会。这些发现支持在专门面向管理措施的框架内保持 SSD 运行的选择。SWOT 分析的结果表明，用围网等半工业渔业取代 SSD 会增加对生态系统的影响，并会导致几个沿海村庄失去社会经济机会。这些发现支持在专门面向管理措施的框架内保持 SSD 运行的选择。SWOT 分析的结果表明，用围网等半工业渔业取代 SSD 会增加对生态系统的影响，并会导致几个沿海村庄失去社会经济机会。这些发现支持在专门面向管理措施的框架内保持 SSD 运行的选择。
