摘　　要：鲐鱼(Scomber japonicus)是西北太平洋主要的经济鱼类之一,在海洋渔业中占有重要的地位。本文在充分了解西北太平洋鲐鱼早期生活史的基础上,采用拉格朗日质点的方法,将FVCOM物理模型和基于个体模型两者进行耦合,构建了基于个体模型的西北太平洋鲐鱼早期生态动力学模型,以预测其早期生命阶段的资源补充量情况与输运分布趋势。本文模拟了平均气候态下,从3月中旬至7月末西北太平洋鲐鱼的资源补充量与鱼卵和仔幼鱼从产卵场向育幼场的输运过程。研究结果表明,所构建的模型可较好地模拟西北太平洋鲐鱼早期生长、资源补充量情况和输运分布趋势;在鲐鱼的补充量方面,3—7月一直持续减少,3—4月份几乎呈直线递减,死亡率最高发生在3月末至4月末期间,5月份开始死亡率逐渐减小,6—7月由于生物因素和环境因素导致仔幼鱼的死亡率降低;在鲐鱼的输运分布方面,鱼卵和仔幼鱼的输运明显受黑潮所控制,一直沿黑潮的主流轴的方向被动输运。Scomber japonicus is one of the main economic fish species in the Northwest Pacific,and plays an important role in the marine fishery of China.Based on the full understanding of the early life history of S.japonicus in the northwest Pacific,in this study,we used lagrange particle method to couple FVCOM physical model and individual-based-model,and constructed an individual-based ecological dynamic model of S.japonicus in the northwest Pacific to predict its transportation distribution and resource recruitment in the early life stage.The recruitment of S.japonicus and the transport of eggs and larvae from ground to the nursery were simulated under normal climate conditions from midMarch to the end of July.The results showed that the model could well simulate the early growth,resource recruitment and transportation trend of S.japonicus in the northwest Pacific.The number of S.japonicus recruitment continued to decrease from March to July,and decreased almost linearly from March to April.The mortality rate reached its peak from the end of March to the end of April.From May,the mortality gradually decreased.From June to July,the mortality of larval fish decreased due to biological and environmental factors.Regarding the transport and distribution of S.japonicus,from the beginning of the simulation to the end,the transport of fish eggs and larvae are obviously controlled by the Kuroshio,and they have been passively transported along the direction of the mainstream axis of the Kuroshio.
