Basic life history parameters of Arctic fishes have not been well characterized for many species in the Chukchi and Beaufort seas. Increasing environmental and anthropogenic changes in the Arctic may impact the biology of Arctic fishes and can best be evaluated if a benchmark is available against which to evaluate future changes in the biology of Arctic fishes. We used data from over 45,000 individual fishes to determine the length and weight relationships of 28 species, and further determined ages of 17 species of Arctic fishes. Specimens that we captured in the Pacific Arctic tended to be small in size, often less than 300 mm, and generally showed positive allometric growth. Despite their small sizes, individuals of some species, especially in Agonidae, Zoarcidae and Stichaeidae, were long-lived, reaching ages of up to 26 years. In the Chukchi Sea, individuals were shorter-lived and tended to be larger and longer-at-age. In contrast, the species that lived longer than a decade reached their maximum ages in the Beaufort Sea. While these long-lived species were smaller at age in the Beaufort Sea, they ultimately reached a greater maximum age than their Chukchi Sea conspecifics. Growth variation can have a large effect on management reference points, and understanding species-specific parameters would be required before any management action is considered, as mandated in the 2009 U.S. Arctic Fisheries Management Plan.

对于楚科奇海和博福特海中的许多物种，北极鱼的基本生活史参数尚未得到很好的描述。北极环境和人为变化的增加可能会影响北极鱼类的生物学，如果有基准可用来评估北极鱼类的未来变化，则最好进行评估。我们使用了来自45,000多种鱼类的数据来确定28种鱼类的长度和重量关系，并进一步确定了17种北极鱼类的年龄。我们在太平洋北极地区捕获的标本尺寸较小，通常小于300毫米，并且通常显示出正向异形生长。尽管它们的个体很小，但其中一些物种的个体寿命长，尤其是在gon科，oa科和St科中，年龄高达26岁。在楚科奇海，个体寿命较短，年龄较大，年龄较大。相反，寿命超过十年的物种在波弗特海达到了最大年龄。尽管这些长寿物种在波弗特海的年龄较小，但最终达到的最大年龄比楚科奇海的物种更大。生长变化可能会对管理参考点产生很大影响，并且根据2009年《美国北极渔业管理计划》的要求，在考虑采取任何管理措施之前，需要了解特定于物种的参数。他们最终达到的最大年龄超过了楚科奇海物种。生长变化可能会对管理参考点产生很大影响，并且根据2009年《美国北极渔业管理计划》的要求，在考虑采取任何管理措施之前，需要了解特定于物种的参数。他们最终达到的最大年龄超过了楚科奇海物种。生长变化可能会对管理参考点产生很大影响，并且根据2009年《美国北极渔业管理计划》的要求，在考虑采取任何管理措施之前，需要了解特定于物种的参数。
