Acadian Seaplants Limited is a Canadian company that produces a marine-plant products for a variety of global**markets. One arm of their company produces a high-value human food product from Irish moss (Chondrus**crispus) through on-land aquaculture. Customers demand 100% seaweed product free of any foreign material**and despite numerous technological and labour-intensive quality control measures implemented by ASL,**customers perform additional quality control practices. The number one customer complaint is insect**fragments. A randomized sampling protocol carried out in the summer of 2017 through the support of an**NSERC Engage grant made two conclusions. First, we determined that rotting wood on tanks is providing**ample habitat for terrestrial isopods - which are commonly recorded as a customer complaint. Second, we**determined that tanks located on the site perimeter contributed disproportionately to insect capture, and**suggested barrier-fencing may be an effective means of reducing insect abundance in production tanks. The**company is using this information to take preventative measures. Currently, ASL is in the process of replacing**wooden supports with composite to remove this resource. In the future, ASL plans to erect fencing around**tanks to prevent insects from inadvertently entering the tank. However, before implementation, ASL must**determine a barrier height which prevents insect entry that simultaneously has little interference with harvesting**equipment. This summer, we propose a continuation of our initial project to determine how insect flight height**is vertically stratified via the use of a randomized passive sampling approach. We believe that analysis of this**data will inform the height of future barriers used to exclude insects and improve product quality.

阿卡迪亚海洋植物有限公司是一家加拿大公司，为各种全球**市场生产海洋植物产品。他们公司的一个分支通过陆上水产养殖从爱尔兰苔藓(Chondrus**Cripus)中生产出一种高价值的人类食品。客户要求100%的海藻产品不含任何异物**，尽管ASL实施了许多技术和劳动力密集型的质量控制措施，**客户仍执行额外的质量控制实践。客户投诉最多的是昆虫碎片。2017年夏天在NSERC Engage赠款的支持下进行的随机抽样方案得出了两个结论。首先，我们确定罐子上腐烂的木头为陆地等足类动物提供了**充足的栖息地--这通常被记录为客户投诉。其次，我们**确定了位于场地周边的储罐对昆虫捕获的贡献不成比例，并**建议屏障围栏可能是减少生产储罐中昆虫丰度的有效手段。**公司正在利用这些信息采取预防措施。目前，ASL正在用复合材料取代**木制支架，以移除这一资源。未来，ASL计划在**坦克周围竖起栅栏，以防止昆虫无意中进入坦克。然而，在实施之前，ASL必须**确定一个屏障高度，以防止昆虫进入，同时对收获设备几乎没有干扰**。今年夏天，我们建议继续我们最初的项目，通过使用随机的被动抽样方法来确定昆虫飞行高度**是如何垂直分层的。我们相信，对这些数据的分析将告知未来用于排除昆虫和提高产品质量的障碍的高度。
