草河豚（Takifugu niphobles）是一种常见于咸水中的外围淡水鱼。在日本宫津的西川，我们发现草河豚在6月和7月从咸水迁移到淡水。大部分草河豚在淡水中平均停留时间为3.6h，白天返回海水。低盐耐受性试验表明，草河豚在淡水中可存活2d，但不超过4d。基于这些发现，我们讨论了迁移的生理效应和生态意义。
The grass puffer,Takifugu niphobles, is a peripheral freshwater fish often seen in brackish water. In the Sai River, Miyazu, Japan, we found that the grass puffer migrate to fresh water from salt water in June and July. Most of the grass puffer stayed in fresh water for 3.6 h on average and returned to the sea during the day. A low salinity tolerance experiment indicated that the grass puffer can live in fresh water for 2 days but not for longer than 4 days. Based on these findings, we discuss the physiological effects and ecological implications of the migration.
