Abstract: To evaluate the growth dynamics and utilization status of fish resources in the Henan section of the main stream of the Yellow River，fish resources were investigated in 11 sections of Henan section of the main stream of the Yellow River in June（summer）and October（autumn）of 2023，January（winter）and May（spring）of 2024. Growth and mortality parameters as well as resource utilization status were analyzed for five dominant fish species Parabramis pekinensis，Carassius auratus，Hemiculter leucisculus，Pseudobrama simoni，Cyprinus carpio by using FiSAT Ⅱ software.The Beverton‐Holt dynamic comprehensive model was applied to assess management strategies. The results showed that the growth index（b）of the five fish species ranged from 3.02 to 3.22，exhibiting positive allometric growth.The growth coefficient（K）was 0.39—0.93，so all of them were rapid growth type.The growth performance index（φ'） was 4.02—5.41.The resource exploitation rate of four fish species，except for Cyprinus carpio，were all lower than the exploitation rate which produces maximum sustainable yield，suggesting that the stocks were not over‐exploited. The results of the Bverton‐Hort dynamic comprehensive model showed that the current catchable body length of Cyprinus carpio was relatively smaller，and increasing the catchable body length was more conducive to the recovery of fish resources than reducing the fishing intensity.Optimal resource protection and management would be achieved by setting size‐at‐first‐capture limits at 236 mm for Parabramis pekinensis，165 mm for Carassius auratus，89 mm for Hemiculter leucisculus，86 mm for Pseudobrama simoni，and 490 mm for Cyprinus carpio.In summary，in the Henan section of the the main stream of the Yellow River，the growth rate of the five dominant fish species showes an accelerating trend；Cyprinus carpio resources are overexploited.

摘要： 为评估黄河干流河南省段鱼类资源生长动态和开发利用现状，于2023年6月（夏季）、10月（秋季），2024年1月（冬季）、5月（春季）对黄河干流河南省段11个断面开展鱼类资源调查。基于FiSAT Ⅱ分析5种优势鱼类——鳊（Parabramis pekinensis）、鲫（Carassius auratus）、䱗（Hemiculter leucisculus）、似鳊（Pseudobrama simoni）和鲤（Cyprinus carpio）的生长、死亡参数及资源利用状况，并应用Beverton-Holt动态综合模型评估管理策略。结果表明，5种鱼类的生长指数（b）为3.02~3.22，均为正异速增长；生长系数（K）为0.39~0.93，均为快速生长型；生长性能指数（φ'）为4.02~5.41；除鲤以外的4种鱼类资源开发率均小于获得最大持续渔获量的开发率，未达到过度捕捞状态。Bverton-Holt动态综合模型的分析表明，当前鲤的开捕体长较小，且增大开捕体长比降低捕捞强度更有利于恢复鱼类资源。鳊、鲫、䱗、似鳊和鲤的开捕体长分别控制在236、165、89、86、490 mm，可更好地保护和管理鱼类资源。综上，黄河干流河南省段5种优势鱼类的生长速度均呈加快趋势；鲤鱼资源被过度开发。
