摘要
研究不同光照强度对太平洋鳕仔鱼摄食的影响。在0～1 000 lx光照范围内,对不同光照强度、摄食不同时间太平洋鳕仔鱼摄食量进行了测定,结果表明:仔鱼500 lx时摄食强度最大,其次为700、300 lx,摄食率在500 lx时最高,并在摄食开始后10 min时达到最大,并随着时间的延长而降低。
The effects of different light intensity on feeding of Gads macrocephalus larvae was studied. The results showed that the feeding intensity was relatively high under 300 lx and 700 lx, and 500 lx was the optimum illumination for the larvae to feed. The feeding rate reached the max in 10 minute under 500 lx ,decreased with the feeding time.
