摘要鱼类早期生活史阶段的常规活动发生在一个中间的水动力环境（由雷诺数确定），在一个区域之间的阻力是线性依赖于速度和阻力的推力作出很大的贡献，和一个区域的惯性力占主导地位，除了在紧邻身体表面的边界层。冲刺性能进行幼虫进入这后一个区域，因此，运动活动的幼虫和成人的生存都很重要，发生在相同的水动力环境和类似的选择压力，预计将影响运动形态的幼虫和成人。评价和解释幼虫发育的最简单的框架是将亲本形式作为发育终点，并使用成虫形式作为参考来识别幼虫结构的相似性和差异。运动结构的三个措施被用来检查在发育过程中的变化：（a）尾柄的比例，…
Abstract Routine activities of early life history stages of fishes occur in an intermediate hydrodynamic environment (as identified by Reynolds numbers), between a zone where drag is linearly dependent on velocity and resistive forces make large contributions to thrust, and a zone where inertial forces dominate except in the boundary layer immediately adjacent to the body surface. Sprint performance carries larvae into this latter zone; thus, locomotor activities important for survival of both larvae and adults occur in the same hydrodynamic environment and similar selective pressures would be expected to influence locomotor morphology of larvae and adults. The simplest framework for evaluating and interpreting development of larvae recognizes the parental form as the developmental terminus and uses adult forms as references to identify similarities and discrepancies in larva structure. Three measures of locomotor structure are used to examine changes during development: (a) the ratio of caudal peduncle d...
