摘　　要：声学方法作为现代渔业资源调查评估方法的重要手段,在北太平洋渔业资源评估中应用日益广泛。其中,目标强度对声学调查评估精度影响重大。目前,已经有许多学者使用不同的方法对北太平洋一些物种的目标强度进行了研究。本文系统梳理了现有的北太平洋主要渔业资源的目标强度及其测量方法,将其归纳总结为原位测量(in situ)、非原位测量(ex situ)和模型法,分析各种方法的优缺点,并根据调查目标种类、现场调查条件等方面对目标强度测量估算方法的选取提出建议,以期为北太平洋重要经济鱼类目标强度测定工作提供参考,为北太平洋重要经济渔业资源声学评估提供科学依据。Acoustic methods are important tools in modern fishery surveys and assessments, and acoustic methods are increasingly used in fishery stock surveys in the North Pacific Ocean. However, the acoustic target strength of fish significantly affects the accuracy of resource estimations determined by acoustic methods. Researchers have studied the acoustic target strength of some species in the North Pacific Ocean using different methods. This paper reviews the existing acoustic target strength of the main fishery resources in the North Pacific Ocean and the methods used to measure this. These methods can be categorized as in situ methods, ex situ methods, and model estimation methods. We analyzed the advantages and disadvantages of each method and provide suggestions on the selection of different acoustic target strength measuring methods according to the target species, conditions of field surveys, and other factors. This paper provides a reference for acoustic target strength measurement of some commercially important fish species in the North Pacific Ocean and provides a scientific basis for acoustic assessment of fishery stocks in this area.
