海水鱼类幼体和幼体阶段的存活率变化很大，在确定招募潜力方面起着关键作用(库欣，1975；胡德，1987)。早期生命的存活是生长和死亡的函数，很明显，这些机制协同作用来决定一个人的存活概率(Houde，1996)。经历快速生长的个体在脆弱的体型范围内花费的时间更少(阶段持续时间缩短)，在给定的年龄达到更大的身体尺寸，从而增强它们发现和逃避捕食者的能力(Bailey和Houde，1989；Fuiman和Magurran，1994)。因此，招募的成功或失败与生命早期阶段的生长和死亡率的变化密切相关。我们目前对早期生命发育和死亡的大部分了解是基于对耳石微结构的检查得出的信息。在许多海洋硬骨鱼耳石上每天沉积的生长增量已经被证明，并为亚热带河口定居后红鱼的生长、死亡和补充潜力提供了一种平均的时空变异性。
Survival during the larval and juvenile stages of marine fishes is highly variable and plays a critical role in determining recruitment potential (Cushing, 1975; Houde, 1987). Early life survival is a function of both growth and mortality, and it is clear that these mechanisms act in concert to determine an individual’s probability of survival (Houde, 1996). Individuals experiencing rapid growth will spend less time in vulnerable size ranges (reduced stage duration) and achieve a larger body size at a given age, thus enhancing their ability to detect and escape predators (Bailey and Houde, 1989; Fuiman and Magurran, 1994). Consequently, recruitment success or failure is closely linked to variation in growth and mortality during the early life stage. Much of our current understanding of early life growth and mortality is based on information derived from the examination of otolith microstructures. The daily deposition of growth increments on otoliths has been demonstrated for many marine teleosts and provides a means Spatial and temporal variability in growth, mortality, and recruitment potential of postsettlement red drum, Sciaenops ocellatus, in a subtropical estuary*
