Flow and stress acclimation both enhance predator avoidance in a common cyprinid fish

I investigated the impact of flow and predator stress acclimation on the swimming performance and predator avoidance ability of juvenile qingbo Spinibarbus sinensis. The experimental subjects were acclimatized for 20 d to nearly still water (control), flowing water, or nearly still water in the pres...
