Individual zebrafish Danio rerio were assayed for exploratory tendency in a serial open field test before and after being maintained on one of four diet treatments that differed in ration and in predictability of food delivery. Danio rerio became more exploratory after being maintained on a diet with a predictable delivery schedule. There was no effect of ration. Thus, exploratory behaviour is inducible by environmental influences independent of genetic predisposition or social interactions. These results have implications for management of correlated behavioural syndromes of exploratory and boldness of animals reared in captivity for later release into wild populations.
个体斑马鱼（Danio rerio）在进行一系列开放式田野测试之前和之后，被分配到四种不同的饮食处理组中，这些处理组在配给和食物供应的可预测性方面存在差异，以此来评估其探索倾向。斑马鱼在可预测的食物供应计划的饮食下，表现出更强的探索倾向。而配给量则没有影响。因此，探索行为是可以通过独立于遗传倾向或社会互动的环境影响来诱导的。这些结果对于管理在圈养中饲养的动物的相关行为综合征（包括探索行为和大胆行为）具有重要意义，因为这些动物在后期会被释放到野外种群中。
