Fish are important components of freshwater and marine ecosystems, are economically important through commercial fisheries and aquaculture, and have further socio-economic value in the form of recreational fishing. Relatively little is known about the details of fish behavior in the field. A major goal of the project is to develop low-cost underwater video techniques that allow analysis of fish swimming behavior. This approach has revealed that some fish use intermittent propulsion while swimming: a swimming mode where short series of tail beats are interrupted by gliding. Information from field swimming videos will be combined with physiological techniques in the lab to measure swimming energy costs and muscle properties. The researchers can then explore the potential advantages of this swimming style, for example we predict that intermittent swimming will reduce energy costs. Energy economy is biologically important for many animals, and low-cost propulsive strategies may also inform the design and operation of underwater vehicles. Improved knowledge of fish behavior and physiology can also inform management of fish habitats, commercial and recreational fisheries, and aquaculture facilities, as well as improve the design of engineered structures with which fish interact such as fish ladders and spillways. Additionally, the project will broaden the participation of underrepresented groups in STEM fields by providing research training opportunities for several undergraduate and high school students.To fully understand the links between locomotion and fitness, the investigators require information on the following: 1) how animals move in their habitats, 2) the factors that underlie the observed patterns of movement, and 3) how these factors affect the performance metrics, such as energy economy, that impact fitness. Field swimming performance data recently obtained by the Principal Investigators indicate that bluegill sunfish use an intermittent propulsive strategy for swimming, a behavior rarely observed under laboratory conditions. Intermittent propulsion is widely used during flight and may also be common during swimming, although detailed field data are scarce. Given their accessibility in their habitat, and suitability for behavioral and physiological data collection in the lab, bluegills are an ideal model system for exploring the potential benefits of intermittent propulsion during fish swimming. The project will use 3D underwater videography to provide the most detailed analysis of fish swimming performance in the field yet attempted. These data will be integrated with laboratory measurements of muscle contractile performance to quantify the potential muscle level constraints that favor intermittent propulsive strategies, and to test long-standing hypotheses regarding the potential energetic advantages of intermittent propulsion in swimming fish. The resulting data will be broadly applicable in interpreting fish behavior in the field and will inform laboratory approaches to ensure performance is measured in ways relevant to organismal fitness. Additionally, the project will provide research training opportunities for several undergraduate and high school students who are recruited from populations that are traditionally underrepresented in STEM fields.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

鱼类是淡水和海洋生态系统的重要组成部分，通过商业渔业和水产养殖具有重要的经济意义，并以休闲渔业的形式具有进一步的社会经济价值。对该领域鱼类行为的细节知之甚少。该项目的一个主要目标是开发低成本的水下视频技术，以分析鱼类的游泳行为。这种方法揭示了一些鱼在游泳时使用间歇性推进：一种游泳模式，其中短系列的尾巴跳动被滑翔打断。来自野外游泳视频的信息将与实验室中的生理技术相结合，以测量游泳的能量消耗和肌肉特性。然后，研究人员可以探索这种游泳方式的潜在优势，例如，我们预测间歇性游泳将减少能量消耗。能源经济对许多动物来说在生物学上是重要的，低成本的推进策略也可以为水下航行器的设计和操作提供信息。提高对鱼类行为和生理学的了解还可以为鱼类栖息地、商业和休闲渔业以及水产养殖设施的管理提供信息，并改善与鱼类相互作用的工程结构的设计，如鱼梯和溢洪道。此外，该项目将通过为一些本科生和高中生提供研究培训机会，扩大代表性不足的群体在STEM领域的参与。为了充分了解运动和健身之间的联系，研究人员需要以下信息：1）动物如何在其栖息地中移动，2）所观察到的移动模式的基础因素，以及3）这些因素如何影响性能指标，例如能源经济，影响健康。主要研究人员最近获得的野外游泳性能数据表明，蓝鳃太阳鱼使用间歇性推进策略进行游泳，这种行为在实验室条件下很少观察到。间歇推进在飞行中广泛使用，在游泳中也可能很常见，尽管详细的现场数据很少。考虑到它们在栖息地的可访问性，以及在实验室中收集行为和生理数据的适用性，蓝鳃金龟是探索鱼类游泳过程中间歇性推进的潜在益处的理想模型系统。该项目将使用3D水下摄像技术，提供迄今为止最详细的鱼类游泳性能分析。这些数据将与肌肉收缩性能的实验室测量相结合，以量化有利于间歇性推进策略的潜在肌肉水平限制，并测试长期存在的关于间歇性推进在游泳鱼中的潜在能量优势的假设。由此产生的数据将广泛适用于解释鱼类在该领域的行为，并将通知实验室的方法，以确保性能的测量方式相关的生物体的健身。此外，该项目将为一些本科生和高中生提供研究培训机会，这些学生来自传统上在STEM领域代表性不足的人群。该奖项反映了NSF的法定使命，并通过使用基金会的智力价值和更广泛的影响审查标准进行评估，被认为值得支持。
