人们对鱼类集群提出了各种解释，包括捕食率2、3、社会因素4和遗传因素1。流体动力学效应似乎是重要的专性学校教育的物种。它们通常表现出迁徙运动4，并且学校通常由相同大小范围的个体组成6，7（具有相似的巡航速度，因为这些取决于体长）以同步和规则的阵列8游泳。在鱼群中，鱼的耐力被发现增加了两倍到六倍。这些因素可能具有实际意义，因为鱼群中有许多具有重要商业价值的鱼种，了解它们可能的速度和耐力有助于设计有效的渔具。
VARIOUS explanations for fish schooling have been put forward1, including the rate of predation2,3, social4and genetic1factors. Hydrodynamical effects appear to be important to obligate schooling species. They commonly show migratory movements4, and the schools usually consist of individuals of the same size range6,7(with similar cruising speeds, as these depend on body-length) swimming in synchronization and in regular arrays8. The endurance of the fish is found to be increased twice to six times when in schools16. These factors may have practical significance, as many commercially important species are found in schools and knowledge of their possible speed and stamina can help design efficient fishing gear.
