Coupling effects of hydrodynamics and predatory activity of Nepthys hombergii (Savigny) (Polychaeta: Nephtyidae) on emigration of Hediste diversicolor (O.F. Müller) (Polychaeta: Nereidae) recruits were assessed in a flume. Experiments carried out in still water conditions and in the flume flow showed that predatory activity of N. hombergii is independent of the presence or the absence of flow and does not statistically influence the recruit emigration rate. It appears, however, that hydrodynamics is an inhibiting factor for the emigration of H. diversicolor which occurs in the absence of flow. The comparison of these results with literature data suggests that recruits could use hydrodynamics to leave an unsuitable habitat according to the species mobility range.
在水槽中评估了霍氏深蛇尾（Savigny）（多毛纲：深蛇尾科）的水动力与捕食活动对多变钩沙蚕（O.F. Müller）（多毛纲：沙蚕科）幼体迁出的耦合效应。在静水条件和水槽水流中进行的实验表明，霍氏深蛇尾的捕食活动与水流的有无无关，且对幼体迁出率没有统计学上的影响。然而，水动力似乎是多变钩沙蚕在无水流情况下迁出的一个抑制因素。将这些结果与文献数据进行比较表明，根据物种的移动范围，幼体可以利用水动力离开不适宜的栖息地。
