采用FVCOM物理模型生成三维物理场,基于个体模型参数化东海鲐鱼早期生物过程,通过拉格朗日质点的方法将模拟生成的3—7月物理场和生物模型进行耦合,构建了基于个体的东海鲐鱼早期生态模型.结果表明:所构建模型可很好地模拟东海鲐鱼鱼卵和仔鱼的输运过程和丰度分布,台湾暖流、黑潮和对马暖流直接影响鱼卵和仔鱼的输运和分布,通过输运到不同育肥场的温度和食物差异间接地影响鱼卵和仔鱼的生长、生存.东海南部产卵场对东海东北部渔场有很大的补充量,但对长江口和舟山外海渔场的补充量很少.产卵场的西北部、西南部与济州岛、对马海峡育肥场之间有很大的连通性,产卵场的东北部、东南部与九州岛、太平洋育肥场之间有很大的连通性.
The FVCOM physics model was used to generate three-dimensional physics field. Based on the individual model, the parameters of the early marine bigeye procession were parameterized, and the simulated 3- The results showed that the model could well simulate the transport process and abundance distribution of fish eggs and larvae in the East China Sea, and the warm current, the Kuroshio current and the warm horse current in Taiwan directly affected the transport of the eggs and larvae Distribution and the difference in temperature and food transported to different fattening farms indirectly affect the growth and survival of fish eggs and larvae.The southern part of the East China Sea spawning ground has a great complement to the fisheries in the northeast of the East China Sea, Replenishment of the fisheries is very small.The northwestern part of the spawning grounds, southwestern part and Jeju Island, have great connectivity to the Mathai Strait fattening farm, and the southeastern part of the spawning grounds, the southeastern part and the Kyushu Island, the pacific fattening farm There is great connectivity between.
