Efficacy of recreational watercraft decontamination practices to prevent the spread of aquatic invasive species

To determine the efficacy of commonly recommended decontamination methods in preventing the overland transport of aquatic invasive species via recreational watercraft, we conducted field and laboratory experiments at the Queen's University Biological Station and Queen's University involving three aquatic invasive invertebrates and three aquatic invasive plants. We assessed the amount of material removed from surfaces by pressure washing, as well as the survival of invertebrates or the viability of plants following brief exposure to hot water, air-drying, and the sequential application of hot water exposure followed by air-drying.为评估常用去污方法在防止水生入侵物种通过休闲水上交通工具进行陆上转运方面的有效性，本研究于女王大学（Queen's University）及女王大学生物站开展野外与室内实验，实验对象涵盖3种水生入侵无脊椎动物与3种水生入侵植物。本研究测定了高压冲洗对载体表面附着物的清除量，并分别评估了水生入侵无脊椎动物经短时热水浸泡、风干，以及先热水浸泡再风干的联合处理后的存活率，与水生入侵植物经上述处理后的存活活力。
