Different kinds of predators of fish species present in nature. In order to investigate whether the prey fish would show specialized anti-predator responses to different predators, in this study, the juvenile crucian carp (Carassius auratus) was selected as prey, and both snake head fish (Channa argus) and catfish (Clarias fuscus) were selected as predators, the crucian carps were exposed to blank (control), snake head fish, catfish and double predators respectively for two months. Then the differences in growth, behavioral traits, morphology, and locomotion performance among different groups were determined. No significant difference in spontaneous activity, utilization of shelter and boldness in crucian carp was found among different groups. The crucian carp from snake head fish, catfish and double predators exposed groups all showed significantly shorter fast-start response latency compared to that of the control group (P<0.05). However, only the fast-start distance moved in 120 ms (S_120ms) and body depth (BD) of snake head fish exposed group was significantly higher than that of the control group (P<0.05). Additionally, no significant difference was found in critical swimming speed (U_crit) and active metabolic rate (M_O2active) among different groups. The improvement of fast-start performance in the crucian carp from snake head fish exposed group may be related to the increase in body depth. Additionally, the fast-start performance may be more important for escaping from predators compared to critical swimming performance. The juvenile crucian carp response to snake head fish more obvious may be because that the snake head fish have larger oral fissure, and bring more serious threat to crucian carp. On the whole, juvenile crucian carp only showed the changed morphology and fast-start performance as the response to predation stress, its behavioral traits maintained no change, which might as a compromise to growth. It is very important for fish species to adapt to the long-term predation pressure existed in habitats.
