鱼类是许多湖泊的重要组成部分，也是许多国家的宝贵资源，但对过去鱼类种群如何波动的了解非常有限。渔业动态信息的一个潜在来源是古湖沼学。本文综述了利用双翅目昆虫Chaoborus（通常被称为幻影蠓）的沉积物遗骸重建过去鱼类种群的存在或不存在。我们提供了一个简短的概述Chaoborus幼虫的生态，并审查的因素被认为是重要的，在确定其分布和丰度。特别是，我们概述了重要的作用，鱼在结构chaoborid组合。我们强调最近的几项研究利用Chaoborus仍然在重建过去的鱼类动态，包括他们在确定酸化和杀鱼剂添加对鱼类种群的影响，并跟踪鱼类引进到以前无鱼的湖泊。最后，我们讨论了其他水生无脊椎动物的潜在应用，如枝角类和摇蚊科，推断鱼类种群的变化，并建议，通过整合这些不同的代理提供的信息，我们可以进一步提高我们的能力，推断过去的鱼类种群的变化。
Fish are an important component of many lakes, and a valuable resource in many countries, yet knowledge of how fish populations have fluctuated in the past is very limited. One potential source of information on fisheries dynamics is paleolimnology. This paper reviews the use of the sedimentary remains of the dipteran insect Chaoborus (commonly referred to as the phantom midge) in reconstructing past presence or absence of fish populations. We provide a brief overview of the ecology of Chaoborus larvae, and review the factors believed to be important in determining their distribution and abundance. In particular, we outline the important role fish have in structuring chaoborid assemblages. We highlight several recent studies utilizing Chaoborus remains in reconstructing past fish dynamics, including their use in determining the effects of acidification and piscicide additions on fish populations, and to tracing fish introductions into previously fishless lakes. We conclude by discussing the potential applications of other aquatic invertebrates, such as the Cladocera and Chironomidae, to infer changes in fish populations, and suggest that by integrating the information provided by these different proxies, we may further improve our ability to infer changes in past fish populations.
