Comparisons of local population growth rates to species averages are valuable for natural resource managers because growth rates provide an integrated evaluation of abiotic and biotic factors that regulate growth in a fishery and may inform management decisions. Thus, species‐specific standard growth models pave the way for fisheries scientists to efficiently complete comparisons, evaluate status, and determine the potential of a fishery for meeting goals and objectives. Growth standards have been published for numerous freshwater fishes; however, growth standards commonly neglect differences among populations of the same species that reside in different habitat types (e.g., lotic versus lentic habitats). Furthermore, studies may use data sets that are based on age estimates from various aging structures, even those with known biases, when creating standard growth models. Our study developed a standard growth model for lotic‐dwelling Smallmouth Bass Micropterus dolomieu based on over 11,000 fish across their range in the United States. Due to differences in parameter estimates between standard growth equations that are generated with otolith‐ and scale‐aged fish, separate standard growth models were created for each structure. Standard growth models were used to calculate the following growth standards: predicted age‐specific standard length, percentile distributions of age‐specific standard length, and estimates of the time required to reach specified size‐classes for each aging structure. Thus, standard growth models and growth standards are presented for the two most common aging structures, which will facilitate comparisons of lotic Smallmouth Bass populations by providing equitable growth equations regardless of the aging structure that is used by researchers.

耳道小嘴鲈的耳石和基于鳞片的生长标准

将本地人口增长率与物种平均水平进行比较对于自然资源管理者来说非常有价值，因为增长率可以提供对调节渔业增长并可能为管理决策提供依据的非生物和生物因素的综合评估。因此，特定物种的标准生长模型为渔业科学家有效地完成比较，评估现状并确定渔业实现目标的潜力铺平了道路。已经发布了许多淡水鱼的生长标准；但是，生长标准通常会忽略居住在不同栖息地类型（例如，抽烟和lentic栖息地）的同一物种的种群之间的差异。此外，研究可能会使用基于各种年龄结构的年龄估算的数据集，即使这些数据具有已知的偏见，在创建标准增长模型时。我们的研究为居住在矮人口中的Smallmouth Bass开发了标准的生长模型在美国，Micropterus dolomieu基于其范围内的超过11,000条鱼。由于用耳石和鳞龄鱼生成的标准生长方程之间的参数估计值不同，因此为每个结构创建了单独的标准生长模型。标准增长模型用于计算以下增长标准：预测的特定年龄标准长度，特定年龄标准长度的百分位数分布，以及估算每个老化结构达到指定尺寸级别所需的时间。因此，针对两种最常见的衰老结构提出了标准的增长模型和增长标准，通过提供公平的增长方程，无论研究人员使用的衰老结构如何，都将有助于比较Lotic Smallmouth Bass种群。
