Abstract
Abstract Patrick PH, Di Giuseppe M, Manolopoulos H, Tai M-K, Poulton S, Wright J. 2020. Entrainment of fish eggs and larvae at an operating nuclear generating station using improved methodology. Lake Reserv Manage. 37:186–198. Entrainment data collected from 7 December 2015 to 22 November 2016 at the Darlington Nuclear Generating Station (DNGS) using automated sampling methodology are discussed in this article, including numbers of fish eggs and larvae entrained. We used a more robust sampling design than previously used in 2004 and 2006, which involved more frequent sampling over a longer, 12 month period. The design allowed collection of daily samples with a longer sampling duration and higher total sample volumes that reduced variability compared to previous studies with less robust sampling throughout a day. Our study resulted in the capture of deepwater sculpin and burbot that were not observed in previous entrainment studies. The maximum entrainment density for eggs was about 17 times higher than that for larvae. The entrainment of fish eggs was highest in the summer months (June and July) and did not vary diurnally. The highest entrainment rates for larvae occurred during the months of August and September, with higher densities entrained at night. We recommend the use of both increased sampling frequency and sampling volumes to characterize fish entrainment for water users in the Great Lakes watershed.使用改进的方法在运行中的核电站捕获鱼卵和幼虫
摘要Patrick PH，Di Giuseppe M，Manolopoulos H，Tai M-K，Poulton S，Wright J.2020。使用改进的方法在运行中的核电站捕获鱼卵和幼虫。湖泊保护区管理。37:186–198。本文讨论了2015年12月7日至2016年11月22日在达林顿核电站（DNGS）使用自动采样方法收集的夹带数据，包括夹带的鱼卵和幼虫数量。我们使用了比2004年和2006年更稳健的采样设计，该设计涉及在更长的12个月内更频繁的采样。该设计允许以更长的采样持续时间和更高的总样本量收集每日样本，与之前全天采样不太稳健的研究相比，这降低了变异性。我们的研究结果捕获了深水双桨和burbot，这在以前的夹带研究中没有观察到。卵的最大夹带密度大约是幼虫的17倍。鱼卵的夹带量在夏季月份（6月和7月）最高，昼夜变化不大。幼虫的最高夹带率发生在8月和9月，夜间夹带的密度更高。我们建议使用增加的采样频率和采样量来表征大湖流域用水者的鱼类夹带情况。

期刊介绍：
Lake and Reservoir Management (LRM) publishes original, previously unpublished studies relevant to lake and reservoir management. Papers address the management of lakes and reservoirs, their watersheds and tributaries, along with the limnology and ecology needed for sound management of these systems. Case studies that advance the science of lake management or confirm important management concepts are appropriate as long as there is clearly described management significance. Papers on economic, social, regulatory and policy aspects of lake management are also welcome with appropriate supporting data and management implications. Literature syntheses and papers developing a conceptual foundation of lake and watershed ecology will be considered for publication, but there needs to be clear emphasis on management implications. Modeling papers will be considered where the model is properly verified but it is also highly preferable that management based on the model has been taken and results have been documented. Application of known models to yet another system without a clear advance in resultant management are unlikely to be accepted. Shorter notes that convey important early results of long-term studies or provide data relating to causative agents or management approaches that warrant further study are acceptable even if the story is not yet complete. All submissions are subject to peer review to assure relevance and reliability for management application.
