Acipenserids (sturgeons) live in large rivers and lakes in North America and Eurasia, where many species and populations are considered imperiled. One of the most pervasive threats across the global range of sturgeon is water resource development (e.g., hydropower dams, water intakes for irrigation, industrial use, or human consumption). We report on the outcome of a literature review focused on interactions between sturgeon and water resource development. We focused on the persistent issue of dam passage (both upstream and downstream), impingement, and entrainment, which are all relevant issues for both existing and planned facilities. We discuss aspects of sturgeon sensory physiology, and how knowledge of sensory physiology can be used for behavioural guidance. We also consider how the swimming ability and style of sturgeon is relevant for passage. Most of the literature emanated from research on just a few species (especially lake sturgeon, white sturgeon, green sturgeon, and shortnose sturgeon). Although there are several examples of apparent “success stories” (e.g., successful upstream fish passage, efforts to reduce impingement and entrainment), there are also many failures, and such examples are likely under-reported. Without significant investments in solutions-oriented research related to sturgeon-water resource development interactions, we submit that fish passage, entrainment and impingement problems for acipenserids will remain. There is a need for research that spans life-stages, compares different species, and considers how passage, entrainment, and impingement influence demography. Further, there is a need for investment into evidence-based implementation of mitigation infrastructure and management strategies to ensure conservation needs of sturgeons are adequately considered.

水资源开发和鲟鱼(Acipenseridae):与鱼类通过、夹带、撞击和行为指导相关的科学和研究差距状况

Acipenserids(鲟鱼)生活在北美和欧亚大陆的大型河流和湖泊中,许多物种和种群被认为处于危险之中。全球范围内鲟鱼最普遍的威胁之一是水资源开发(例如,水电大坝、灌溉用水、工业用水或人类消费)。我们报告了以鲟鱼与水资源开发之间的相互作用为重点的文献综述的结果。我们专注于大坝通过(上游和下游)、撞击和夹带的持续问题,这些都是现有和规划设施的相关问题。我们讨论了鲟鱼感官生理学的各个方面,以及如何将感官生理学知识用于行为指导。我们还考虑了鲟鱼的游泳能力和风格与通过的关系。大多数文献来自对少数物种(尤其是湖鲟、白鲟、绿鲟和短鼻鲟)的研究。虽然有几个明显的“成功故事”的例子(例如,成功的上游鱼类通过,努力减少撞击和夹带),但也有许多失败,这些例子很可能被低估了。如果不对与鲟鱼-水资源开发相互作用相关的以解决方案为导向的研究进行大量投资,我们认为鲟鱼的鱼类通过、夹带和撞击问题仍将存在。需要进行跨越生命阶段的研究,比较不同的物种,并考虑通道、夹带和撞击如何影响人口统计学。更多,
