通过数值试验研究了日本骏河湾亮尾草卵和幼虫的输运过程，重点研究了河水扩散的物理效应。实验中，将标记粒子视为无（或弱）游泳能力的亮球藻卵或早期幼虫，在海洋环流模式计算的流场中进行被动输运。在没有大陆架的海湾最里面的区域（富士河口外），卵和幼虫可以在营养丰富的环境中停留很长一段时间的滞留区，特别是在它们的居住层的上部，由反气旋（顺时针）环流的大凸起形成。在海湾西部地区（Oi河口和Abe河口附近）没有形成保留区，在另一个实验中，在最里面的区域人工建立了一个大陆架。据估计，在保留区，卵和早期幼虫的停留时间延长约一个月。滞留区的形成受河水扩散动力学控制，受海底地形和地球自转的影响。此外，还对骏河湾中的亮球藻数量较多的原因进行了讨论。
Numerical experiments were performed to investigate the transport processes of eggs and larvae of Sergia lucens in Suruga Bay, Japan, focusing on the physical effects of the river water spreading. In the experiments, labeled particles, which were regarded as the eggs or early larvae of S. lucens with no (or weak) swimming ability, were passively transported in flow fields that were calculated by an ocean general circulation model. In the innermost region of the bay (off the Fuji River mouth) where there is no continental shelf, a retention area where the eggs and larvae could stay in a nutrient-rich environment for a long time was formed, especially in the upper part of their habitation layers, by the large bulge with anticyclonic (clockwise) circulation. No retention area was formed in the western region of the bay (off the Oi and Abe River mouths) or in an additional experiment in which a continental shelf was artificially created in the innermost region. It was estimated that in the retention area, the residence time of the eggs and early larvae is prolonged by about a month. The formation of the retention area is controlled by the dynamics of the river water spreading, affected by the bottom topography and the Earth’s rotation. Moreover, the reason why S. lucens are only caught in abundance in Suruga Bay was discussed.
