光照对真鲷仔、稚、幼鱼摄食的影响

Influence of light on feeding of larval,juvenile and young red sea bream

光照对真鲷（Pagrosomusmojor）仔、稚、幼鱼的摄食有重要影响。摄食的适宜光照度范围为100～102lx，最适光照度范围为101～102lx。103lx强光对仔鱼摄食的影响大于稚、幼鱼；100lx弱光对9d以前的仔鱼和稚、幼鱼的摄食影响较小，对9d以后的仔鱼影响较大。此结果和鱼的感觉器官发育及鱼所摄食的饵料种类有关。

The feeding of larval,juvenile and young red sea bream (Pagrosomus major) is influenced greatly by illumination. The light intensity suitable for feeding ranges from 100lx to 102lx, and the optimum from 101lx to 102lx. The strong light of 103lx influences the larvae more greatly than the juvenile and the young. The weak light of 100lx influences more greatly the post-iarvae than the early-larvae,juvenile and young. These results may be correlated with the development of sense organs and the sorts of food.
