采用野外观察和数值实验相结合的方法，研究了三瘤蟹（Portunus trituberculatus）在日本日中那都的捕蟹策略。在三维数值模型中计算的动物和巨蛋石阶段的扩散模式准确地再现了观察到的模式。1、2、3、4虫区垂直迁移模式的时间变化在三管圆孔虫从产卵地向苗圃的迁移过程中起着重要作用。
The recruitment strategy of swimming crabs, Portunus trituberculatus, was investigated by field observations and numerical experiments in Hiuchi-Nada, Japan. Calculated dispersal patterns of zoeal and megalopal stages in a three-dimensional numerical model reproduce observed patterns accurately. The temporal change of vertical migration patterns between the 1st and 2nd zoeas and the 3rd and 4th zoeas plays an important role in the process of recruitment of P. trituberculatus from spawning ground to nursery ground.
