To investigate the differences in group decision making between conspecific and heterospecific shoals composed of Chinese bream (Parabramis pekinensis) and qingbo (Spinibarbus sinensis) juveniles, the 10 Chinese bream composed of 10B group, 5 Chinese bream and 5 qingbo composed of 5B5Q group, and 10 qingbo composed of 10Q group in the shoal cohesion, shoal distribution, shoal movement characteristics and other shoal behavior parameters were compared and analyzed.The results show that: 1) there was no statistical significance in the effects of shoal composition on shoal cohesion, distribution density of maze arm and maze center, grouping frequency and duration, whereas the percent time in group of 10B was significantly lower than those of 5B5Q and 10Q (p<0.05). 2) There was no statistical difference in the group moving frequency among three shoals, whereas frequency of achieved group movement of 10B were significantly lower than that of 10Q (p<0.05). 3) In the heterospecific shoals, the proportion of qingbo as the leader was higher significantly than that of Chinese bream in all group movements and all achieved group movements (p < 0.05), whereas there was no significant difference between the two species as the leader in the failed group movements. These results suggest that qingbo shoals are easier to fulfill group decision making behavior successfully than Chinese bream shoals, and have more leadership ability than Chinese bream, which may be related to the stronger swimming capacity and bolder and more explorative of qingbo than Cinese bream.
