When feeding on mysid swarms (Paramesopodopsis rufa), juvenile Australian salmon (Arripis trutta) had higher rates of successful attacks when foraging in a group of six fish (55% total advances) than when foraging alone (39% total advances). Six schooling fish had lower approach rates than solitary fish (25% and 37% of total advances, respectively). This result indicated that schooling fish were better at reducing the confusion effect of swarming prey, resulting in more efficient feeding. In larger areas, schools achieved higher rates of successful attacks (19 prey/fish in the large tank, compared with 11 prey/fish in the smaller tank). There was no influence on the feeding success of individual fish when changes were made to the number of prey presented to each fish. Nearest neighbour distances were smallest in the absence of prey, and increased with the introduction of prey and again in an attack sequence. Six fish schooled more cohesively than three fish, indicating increased benefits of schooling in larger groups that contribute to advanced vigilance and foraging techniques.

学校教育会影响澳大利亚鲑鱼 (Arripis trutta) 在捕食糠虾群 (Paramesopodopsis rufa) 时的取食成功

当以糠虾群 (Paramesopodopsis rufa) 为食时，澳大利亚幼鲑 (Arripis trutta) 在一组六条鱼中觅食时的成功攻击率（总进步 55%）比单独觅食时（总进步 39%）更高。六种鱼群的接近率低于独居鱼（分别占总进步的 25% 和 37%）。这一结果表明，群居鱼能更好地减少蜂拥而至的猎物的混淆效应，从而提高捕食效率。在较大的区域，鱼群的成功攻击率更高（大水箱中 19 条猎物/鱼，而小水箱中 11 条猎物/鱼）。当每条鱼的猎物数量发生变化时，对每条鱼的摄食成功没有影响。在没有猎物的情况下，最近邻距离最小，并随着猎物的引入而增加，并在攻击序列中再次增加。六条鱼比三条鱼更有凝聚力，这表明在更大的群体中进行训练的好处增加，这有助于提高警惕和觅食技术。
