| 摘 要： | 在10^3-10^-1lx光照度范围内，南方鲇稚鱼对团鲂鱼苗的摄食强度随光照度减弱而增强，在10^9lx时达最大值，随后下降，摄食率在开始摄食后10min，光照强度为10^0lx时最同，并随摄食时间延长而下降。

| Abstract: | The feeding intensity of southen sheatfish ( Silurus meridionalis ) was affected by illuminance. Under both the strong light of 10 3 lx and the weak light of 10 -1 lx, the feeding intensity was relatively weak, the highest feeding intensity was observed under 10 0 lx and an optimum illuminnce found for the feeding. The feeding rate decreased with the feeding time about 10 min after feeding. The feeding dynamics of the juvenile under different feeding conditions, that is, the curve of feeding dynamics, was similar in trends to the curves of feeding intensity and feeding rate.
