The coexistence of aquaculture and inshore fisheries in Scotland: An ecotoxicological approach to establish potential contamination pathways in commer

该项目解决的总体研究问题是：水产养殖治疗剂和其他遗留污染物与商业上重要的甲壳类动物有关的生物和环境途径是什么？这些途径与观察到的病理（如贝壳病）之间是否存在关联？如何利用规划和管理来中断这些途径中的关键环节？鉴于邻近水产养殖和渔场，当地对潜在相互作用的关注，以及HEI合作伙伴参与渔业监测活动的机会，奥克尼水域提供了一个理想的机会来审查这些联系，特别关注N. puber。在奥克尼岛的一个特定地点，已注意到N. puber畸形和病变的高发生率，并考虑到靠近水产养殖设施的问题，认为值得进一步调查。赫瑞瓦特大学的一个理学硕士项目（2018年6月至8月）在另一个地点（也靠近水产养殖设施）发现了N. puber组织中的污染物化学残留物（以前从未记录过，细节保密）。虽然在这个小规模的研究中没有建立化学物质与黑斑病变或畸形之间的因果关系，但提出了一个更广泛更详细的抽样计划：(1)确定奥克尼岛N. puber种群中黑斑和畸形的频率；(2)在养殖设施的允许影响范围内，绘制水虫的迁移图谱，确定遇虫频率；(3)分析与水产养殖相关的化学治疗剂（当前和遗留）的阳蟹（和其他商业上重要的螃蟹，如大闸蟹）组织；(4)在有记录的畸形和黑斑高发的地方调查其他具有脱模抑制能力的遗留化学污染物。

The overall research questions addressed by this project are: what are the biological and environmental pathways of aquaculture therapeutants and other legacy contaminants in relation to commercially important crustaceans? Is there an association between these pathways and observed pathologies such as shell disease? And, how can planning and management be used to interrupt critical links in these pathways? Given close proximity of aquaculture and fisheries grounds, local concerns about potential interactions, and access of the HEI partners to fishery monitoring activities, Orkney waters provide an ideal opportunity to examine these links, with a particular focus on N. puber.High incidences of deformities and lesions in N. puber have been noted in one particular location in Orkney and concerns regarding the close proximity of an aquaculture facility was considered merit for further investigation. An MSc project (June-Aug 2018) at Heriot-Watt University revealed contaminant chemical residues in the tissues of N. puber (never previously recorded, details remain confidential) at a different location, also in close proximity to an aquaculture facility. Whilst, no causal link between the chemical and the black-spot lesions or deformities was established in this small-scale study, a wider more detailed programme of sampling is proposed to: (1) determine the frequency of black-spot and deformities in N. puber populations in Orkney; (2) map N. puber mobility and determine frequency of encounters in allowable zone of effect under aquaculture facilities; (3) analyse N. puber (and other commercially important crabs, e.g. Cancer pagurus) tissues for chemical therapeutants associated with aquaculture (current and legacy); (4) investigate other legacy chemical contaminants with moulting-inhibitor abilities at locations where a high incidence of deformities and black-spot has been recorded.
