早期检测水系统中的德雷森物种对于维持大坝相关结构的结构和功能至关重要。如果及早发现贻贝，设施运营商可能有大约三到五年的时间来调整系统，直到贻贝数量大到足以限制水流、堵塞管道、限制进水、影响冷却系统并阻碍发电。然而，使用当前方法对水中的德雷森生物进行早期检测存在一些固有的问题，即采样的可变性和分析方法的可靠性，这造成了管理决策的困境。由于目前这些贻贝的控制方法在调节水系统中非常有限，因此垦务局正在进行深入研究。为了改善水系统的早期检测，Reclamation 开发了一种分析策略，包括交叉偏光显微镜、扫描电子显微镜 (SEM)、流式细胞仪和聚合酶链式反应 (PCR)。这种分析策略用于使用浮游生物拖网收集的水样，主要从水库收集，也从设施内的水流（通常来自水龙头或管道）收集。
Early detection of dreissenid species in water systems is critically important to maintaining structure and function of dam related structures. If mussels are detected early, facility operators may have approximately three to five years to adjust systems before the population of mussels are large enough to restrict the flow of water, clog pipes, restrict water intakes, affect cooling systems, and impede power generation. However, early detection of dreissenids in water with the current methods has some inherent issues with variability in sampling and reliability with analytical methods which creates management decision dilemmas. Since current control methods of these mussels are very limited in regulated water systems, Reclamation is conducting intensive research. To improve early detection in water systems, Reclamation has developed an analytical strategy that includes cross polarized light microscopy, scanning electron microscopy (SEM), flow cell cytometry, and polymerase chain reaction (PCR). This analytical strategy is used on water samples collected using a plankton tow net to collect primarily from reservoirs and also from water flow within facilities, usually from a tap or pipe.
