Migration, reproduction, and predator-prey interactions depend heavily on a fish's ability to swim. Swimming efficiency and performance is related to a species' physiology, morphology and behaviour, and the environmental challenges the animal faces (e.g., temperature changes, velocity changes). The focus of my research program is to understand the influence of various abiotic and biotic factors on the swimming capacity and energetics of the sturgeon, a "primitive fish." The rationales for utilizing the sturgeon as a model are many-fold, including: (i) biological, because of its intermediate evolutionary position between sharks and teleosts; (2) their excellent capacity to deal with acute and chronic stressors; (3) commercial, owing to their highly-prized meat and caviar; (4) conservation, as many populations of sturgeon are considered to be critically endangered due to overharvesting and habitat degradation/encroachment. Our recent findings show that sturgeon possess unique morphological and behavioural attributes that affect their swimming patterns (e.g., station-holding) and performance (e.g., length of time swimming).

迁移、繁殖和捕食者与猎物的相互作用在很大程度上取决于鱼的游泳能力。游泳效率和表现与物种的生理、形态和行为以及动物面临的环境挑战有关（例如，温度变化、速度变化）。我的研究计划的重点是了解各种非生物和生物因素对鲟鱼（一种“原始鱼类”）的游泳能力和能量学的影响。“利用鲟鱼作为模型的理由是多方面的，其中包括：㈠生物方面的，因为鲟鱼在进化上处于鲨鱼和硬骨鱼之间的中间位置; ㈡鲟鱼处理急性和慢性应激源的能力极佳; ㈢商业方面的，因为鲟鱼的肉和鱼子酱价值很高;（4）保护，由于过度捕捞和生境退化/侵蚀，许多鲟鱼种群被认为是极度濒危的。我们最近的研究结果表明，鲟鱼具有独特的形态和行为属性，影响他们的游泳模式（例如，站保持）和性能（例如，游泳的时间（）我
