ABSTRACT: Sea lice are a major health hazard for farmed Atlantic salmon in Europe, and their impact is felt globally. Given the breadth of ongoing research in sea lice dispersal and population modelling, and focus on research-led adaptive management, we brought experts together to discuss research knowledge gaps. Gaps for salmon lice infection pressure from fish farms were identified and scored by experts in sea lice-aquaculture-environment interactions, at an international workshop in 2021. The contributors included experts based in Scotland, Norway, Ireland, Iceland, Canada, the Faroe Islands, England and Australia, employed by governments, industry, universities and non-government organisations. The workshop focused on knowledge gaps underpinning 5 key stages in salmon lice infection pressure from fish farms: larval production; larval transport and survival; exposure and infestation of new hosts; development and survival of the attached stages; and impact on host populations. A total of 47 research gaps were identified; 5 broad themes emerged with 13 priority research gaps highlighted as important across multiple sectors. The highest-ranking gap called for higher quality and frequency of on-farm lice count data, along with better sharing of information across sectors. We highlight the need for synergistic international collaboration to maximise transferable knowledge. Round table discussions through collaborative workshops provide an important forum for experts to discuss and agree research priorities.

鲑鱼养殖场海虱感染压力建模的差距分析。二. 识别知识差距并对其进行排名：国际研讨会的成果

摘要：海虱是欧洲养殖大西洋鲑鱼的主要健康危害，其影响遍及全球。鉴于正在进行的海虱传播和种群建模研究的广度，以及以研究为主导的适应性管理的重点，我们将专家聚集在一起讨论研究知识差距。在 2021 年的国际研讨会上，海虱-水产养殖-环境相互作用专家确定了养鱼场鲑鱼虱感染压力的差距并进行了评分。贡献者包括来自苏格兰、挪威、爱尔兰、冰岛、加拿大、法罗群岛的专家、英国和澳大利亚，受雇于政府、工业界、大学和非政府组织。研讨会重点讨论了养鱼场鲑鱼虱子感染压力的 5 个关键阶段的知识差距：幼体生产；幼虫的运输和生存；新宿主的暴露和感染；附属阶段的发展和生存；以及对东道国人口的影响。总共发现了 47 个研究空白；出现了 5 个广泛的主题，其中 13 个优先研究差距被强调为跨多个部门的重要内容。排名最高的差距要求提高农场虱子计数数据的质量和频率，以及更好地跨部门共享信息。我们强调需要进行协同国际合作，以最大限度地提高可转让知识。通过合作研讨会进行的圆桌讨论为专家们讨论和商定研究重点提供了一个重要的论坛。
