　　采用物理环境因子，确定鲐鱼仔幼鱼运动和物理环境之间的响应关系，建立起了基于个体具有游泳行为的鲐鱼早期生长史模型。结果表明，具有游泳行为仔幼鱼前期对输运分布的影响不大，后期随着游泳能力的增强，逐渐在温盐梯度较大锋面，靠近暖水的一侧进行集群和滞留，并使向东北输运速度降低，输运到太平洋和日本海的幼鱼数量下降，所处水深降低，适应生长发育，死亡率降低。产卵场位置的变动使偏西产卵的集群受台湾暖流影响较大，导致集群偏西，主要聚集在偏北的台湾暖流水和长江冲淡水交汇区高温、高盐一侧。偏东产卵受黑潮影响较大，集群偏东，不形成大量聚集和滞留；在生存率方面正常产卵位置是最佳产卵位置。研究认为，物理环境和生物因素同样会对具有游泳行为仔幼鱼的输运和补充产生影响。

The response relationship between Scomber japonicus larval motion and physical environment was deter-mined using physical environmental factors. An IBM (individual-based model, IBM) including a swimming behavior submodel was developed. The result show that the impact of larval swimming behavior on transport of larvae and young juvenile is minor. With the increase in swimming ability as they grow up, larvae could gradually appear to school and made retain in larger-gradient frontiers of temperature and salinity near warm water. Speed of northeastward transport is reduced. The amount of larvae transported to the Pacific Ocean and the Japan Sea would decline. With the increase in swimming ability, the fish could move to their favorable environment of shallow water to grow. Larval mortality is then reduced. Variability of spawning ground affects the western spawning area due to Taiwan Warm Current, resulting in westward schooling of the larvae. Main school would be near higher temperature and salinity to the north where Taiwan Warm Cur-rent and the Changjiang River dilute water met. The eastern spawning area would be influenced by the Kuroshio, causing eastward larvae schooling without in-situ large-scale school and retention. In term of survival rate, normal spawning area shall be the best among the three spawning areas. Therefore, both physical environment and biological factors can affect fish transport and recruitment.
