Factors Analysis of Affecting Cannibalism in Silurus soldatovi Larvae
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.
