Age‐ or length‐structured stock assessments require reliable life history demographic parameters (growth, mortality, reproduction) to model population dynamics, potential yields and stock sustainability. This study synthesized life history information for 84 commercially exploited tropical reef fish species from Florida and the U.S. Caribbean (Puerto Rico and the U.S. Virgin Islands). We attempted to identify a useable set of life history parameters for each species that included lifespan, length at age, weight at length and maturity at length. Key aspects of the life history synthesis were development of: (a) a database that characterized study details including sampling region, biological and statistical methods, length range of sampled individuals, sample size, capture gears and sampling time frame; (b) reproducible procedural criteria for parameter identification for a given species; and (c) a reliability metric for each parameter type. Complete life history parameter sets were available for 46 species analysed. Of these, only 16 species had parameter sets meeting the highest standards for reliability, highlighting future research needs.

佛罗里达和加勒比开发的珊瑚礁鱼类的生活史人口统计学参数合成

年龄或长度结构的种群评估需要可靠的生活史人口统计学参数(生长,死亡率,繁殖)来模拟种群动态,潜在产量和种群可持续性。这项研究综合了来自佛罗里达和美国加勒比海(波多黎各和美属维尔京群岛)的84种商业开发的热带礁鱼物种的生命史信息。我们试图为每个物种确定一套有用的生命历史参数,包括寿命,年龄长短,体重长短和成熟度长。生活史综合的关键方面是:(a)一个数据库,其特征是研究细节,包括采样区域,生物学和统计方法,被采样个体的长度范围,样本大小,捕获装置和采样时间框架;(b)可重复的程序标准,用于确定给定物种的参数;(c)每种参数类型的可靠性指标。完整的生命史参数集可用于分析的46个物种。在这些物种中,只有16个物种的参数集符合最高的可靠性标准,从而突出了未来的研究需求。
