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

该项目涉及的总体研究问题是：水产养殖治疗药物的生物和环境途径是什么，以及与具有重要商业价值的甲壳动物有关的其他遗留污染物？这些途径与观察到的贝壳病等病理之间是否存在关联？而且，如何利用规划和管理来中断这些途径中的关键环节？鉴于靠近水产养殖和渔场，当地对潜在相互作用的担忧，以及HEI合作伙伴对渔业监测活动的可获得性，奥克尼水域提供了检查这些联系的理想机会，特别关注青春期新月球藻。赫里奥特-瓦特大学的一个理科硕士项目(2018年6月至8月)发现，在另一个地点，也是在一个水产养殖设施附近，在P.puber(以前从未记录过，细节仍属机密)的组织中存在污染物化学残留物。虽然在这项小规模研究中没有确定这种化学物质与黑斑病变或畸形之间的因果联系，但建议了一个更广泛、更详细的抽样方案，以：(1)确定奥克尼青蟹种群中黑斑和畸形的频率；(2)绘制青蟹种群的活动图，并确定在水产养殖设施下允许影响区的遭遇频率；(3)分析青蟹(和其他商业上重要的螃蟹，例如癌症)组织中与水产养殖(当前和遗留)相关的化学疗法；(4)在变形和黑斑高发地点调查其他具有蜕皮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.
