Juveniles in the Japan Sea form of three-spined stickleback Gasterosteus aculeatus collected from a tidal pool in eastern Hokkaido Island, Japan, had a unimodal standard length (L(S)) frequency distribution in each period, ranging from 11.9 to 31.6 mm, and those of sea-run migrating individuals collected from the outlet of this tidal pool ranged from 17.0 to 36.0 mm, suggesting juveniles of this form would migrate towards the sea when they reached >17.0 mm. In general linear models (GLM) for testing the best model, there was a relationship between the number of sea-run migratory individual and precipitation, which suggests that precipitation may trigger migration.
日本海银大麻哈鱼幼鱼在北海道岛东部潮池采集，其体长（L(S)）呈单峰频率分布，范围为 11.9 至 31.6 毫米，洄游到该潮池出口的海生洄游个体体长范围为 17.0 至 36.0 毫米，表明该形式的幼鱼在达到 >17.0 毫米时会向海洋洄游。在检验最佳模型的一般线性模型（GLM）中，海生洄游个体数量与降水之间存在关系，这表明降水可能引发洄游。
