摘 要：
对影响怀头鲶(Silurus soldatovi)自残行为的因素进行了研究。以怀头鲶仔稚鱼作为研究对象,分别考察饲养密度、饥饿、光照周期、容器颜色、个体大小5种因素对其自残行为的影响。结果发现,饲养密度、饥饿、光照周期、个体大小对怀头鲶仔稚鱼自残行为影响显著,其中饥饿对其自残行为影响最大,24 h后自残死亡率最高可达70.0%;容器颜色对其影响不显著,投饵可以缓解仔稚鱼的死亡,但不能从根本上解决怀头鲶仔稚鱼自残行为,建议生产上适时下塘、及时投饵,并积极探索新的养殖方法。

摘 要：
Studies were performed to investigate the factors affecting Silurus soldatovi larvae cannibalism,including density,hunger,lighting cycle,container color and body size.The results showed that there were significant infulence of density,hunger,lighting cycle and body size to the fish larvae cannabalim.Hunger had the most influence on fish larvae cannabalim,and 24 h hungry lead to 70.0% cannibalistic death rate.Container color had no significant infulence to cannibalism,and feeding could alleviate the larval mortality,but not fundamentally solve the problem of S.soldatovi larvae cannabalim.It suggested that during production timely stocking down,timely feeding,and explore new method.
