This project will analyze how cartilages, bones, and muscles develop in the various stages of developing fish larvae and juveniles. Changes in the proportions and relative sizes of the skeletal elements and muscles will result in drastic changes in the respiratory and feeding abilities. Whether a developing fish will survive these critical periods depends on the proper timing and differentiation of functional systems which will be studied in this project. It is known that there is an enormously high mortality of fish larvae during critical developmental stages. These studies will elucidate the patterns and mechanisms of development in fishes with free-living larvae and in live-bearing fishes in which the larvae are protected from environmental hazards. By comparing these two groups it will be possible to gain a precise knowledge of the factors governing the development of fishes. Such a study is expected not only to promote theoretical evolutionary knowledge, but also practical applications in reducing or managing mortality of fish larvae.

这个项目将分析软骨、骨骼和肌肉 在幼鱼发育的各个阶段发育， 青少年。 的比例和相对大小的变化， 骨骼元素和肌肉将导致剧烈的变化， 呼吸和进食能力。 无论是一条正在发育的鱼 能否在这些关键时期幸存下来取决于适当的时机 和分化的功能系统，这将是研究 在这个项目中。 据了解，有一个非常高的 在关键发育阶段的幼鱼死亡率。 这些研究将阐明 在具有自由生活的幼虫和活的生育期的鱼类中的发育 保护幼虫不受环境影响的鱼类 隐患 通过比较这两个群体， 准确了解影响发展的因素 鱼。 这样的研究不仅可以促进 理论上的进化知识， 在降低或控制鱼苗死亡率方面的应用。
