A historical analysis was conducted to evaluate monitoring data in the coastal and estuarine waters of Northern Ireland over the 20-year period between 2001 and 2022 to identify current and emerging concerns and gaps in analysis relative to the sustainability of the aquaculture industry. The effects of biological factors such as the presence of harmful algal bloom phytoplankton and marine biotoxins, and environmental factors such as chemical contamination and the water quality on shellfish production were analysed. The influence of key meteorological factors, such as sea temperature, rainfall and sunshine hours, on the levels of environmental factors was also examined. The evaluation included a socio–economic perspective, exploring the impact of the shellfish industry on the Northern Irish economy and the surrounding communities. The article examined the challenges faced by shellfish producers in terms of regulatory compliance and market access, and provides suggestions for comprehensive environmental monitoring strategies, in particular improved sampling plans to be employed to address these challenges. Overall, the compilation analysis discovered that while the shellfish industry in Northern Ireland faces a number of challenges, it remains a valuable source of local employment and income, and has the potential for growth in the coming years. The findings presented will be of interest to researchers and policymakers in the aquaculture industry, and presents a valuable historical contribution on the evaluation of chemical and microbiological contaminants affecting shellfish production that may be useful for other production areas.

与北爱尔兰贝类生产相关的环境和生物因素：来自 20 年区域监测数据的见解


进行了一项历史分析，以评估 2001 年至 2022 年 20 年期间北爱尔兰沿海和河口水域的监测数据，以确定当前和新出现的与水产养殖业可持续性相关的问题和分析差距。分析了生物因素（如有害藻华、浮游植物和海洋生物毒素）和环境因素（如化学污染和水质）对贝类生产的影响。还研究了关键气象因素（如海水温度、降雨量和日照时间）对环境因素水平的影响。评估包括社会经济视角，探讨了贝类产业对北爱尔兰经济和周边社区的影响。本文研究了贝类生产商在监管合规和市场准入方面面临的挑战，并为全面的环境监测策略提供了建议，特别是为应对这些挑战而采用的改进采样计划。总体而言，汇编分析发现，虽然北爱尔兰的贝类产业面临许多挑战，但它仍然是当地就业和收入的宝贵来源，并具有未来几年的增长潜力。所提出的研究结果将引起水产养殖业研究人员和政策制定者的兴趣，并为评估影响贝类生产的化学和微生物污染物提供宝贵的历史贡献，这些污染物可能对其他生产领域有用。
