| 摘 要： | 暗纹东方鲀育苗期饵料不同投喂量与成活率的关系表明，苗期相互残食是其行为特征．鱼苗饱食时残食减轻，饥饿时残食加重．鱼苗个体大小差异不显著时残食减轻，差异显著时残食加重．喂食人工饵料的驯化完成后，残食现象大大减轻．

| Abstract: | The relationship between the feed quantity and the survival rate of Fugu obscurus fries during the early growing period was studied, the result showed that the murdering behavior is a behavioral character of puffer fish fries.Mutual slaughter was decreased when fries had enough food,and increased when fries was hungry. The difference of body size is another factor for murdering behavior, the largest difference is, the more mutual slaughter.After the fries adapted the mixed feed, the murdering behavior is not very obvious. |
