Lice shielding skirts are a preventative measure against salmon lice in Atlantic salmon farming. The skirt is wrapped around the top meters of the net cage to divert the current flow around the cage, and thereby keep the salmon lice out. Despite these skirts being used actively in Norwegian aquaculture for the past decade, there is no standardised way of using them, and therefore type, depth and operating procedures vary between sites. The academic literature on the lice shielding efficiency of these skirts is not extensive and reported efficiency varies across studies and sites with some reporting favourable results, while others find none. Some also report of welfare related issues, with dissolved oxygen levels being the most prevalent, but this too varies across sites and through the production cycle.

The aim of this paper is to provide a comprehensive overview and summary of relevant academic and grey literature from the last decade to identify knowledge gaps that must be filled to achieve optimal use of lice shielding skirts. This paper focuses on three main topics: lice shielding efficiency, interaction with the current flow and rearing challenges. The positive results from some sites indicate that skirts have potential as a tool against salmon lice, however, to create a best practice recommendation for skirt use, more knowledge is necessary on the interaction between skirt and the environment, and sufficient monitoring procedures and decision-making tools must be established.

虱子防护裙是大西洋鲑鱼养殖中鲑鱼虱子的预防措施。裙边缠绕在网笼的顶部米处，以转移笼子周围的电流，从而将鲑鱼虱子挡在外面。尽管过去十年挪威水产养殖业积极使用这些裙边，但没有标准化的使用方式，因此不同地点的类型、深度和操作程序各不相同。关于这些裙子的虱子屏蔽效率的学术文献并不广泛，并且报告的效率因研究和站点而异，一些报告的结果良好，而另一些则没有。一些人还报告了与福利相关的问题，其中溶解氧水平最为普遍，但这也因地点和生产周期而异。

本文的目的是对过去十年的相关学术和灰色文献进行全面概述和总结，以确定必须填补的知识空白，以实现虱子防护裙的最佳使用。本文重点讨论三个主要主题：虱子屏蔽效率、与当前流动的相互作用和饲养挑战。一些网站的积极结果表明，裙边有潜力作为对抗鲑鱼虱的工具，但是，要为裙边的使用制定最佳实践建议，需要更多关于裙边与环境之间相互作用的知识，以及足够的监测程序和决策——必须建立制造工具。
