于1995年2－5月，在L：D为4：20，8：16，12：12和24：0四种光周期条件下，用卤虫无节幼体作饵料培养罗氏沼虾幼体，测定其生长和能量收支。结果表明，随着光照时间（对的延长，幼体生长率（g）增大，两者关系为：g＝6．5245＋3．6045lnT,但光周期对幼体C，N含量和C：N值没有显著的影响；与最短的光照条件相比，长光照条件下摄食能分配于生长的比例增加9．5％，损失于排粪排泄的比例减少7．7％。实验证明，长光照特别是连续光照能提高幼体的生长率和能量效率，可为幼体大量培育时提高生产效益的有效措施。
From February to May in 1995, the larvae of Artemisia macrophylla were cultured with Artemia nauplii under the four photoperiod conditions of L: D of 4: 20,8: 16,12: 12 and 24: 0. Its growth and energy budget. The results showed that with the increase of illumination time, the growth rate of juveniles (g) increased, the relationship between them was: g = 6.5245 + 3.6045lnT, but the photoperiod did not significantly affect the contents of C, N and C: N Compared with the shortest light conditions, the proportion of long-exposure light that can be allocated to growth increased by 9.5%, and the loss from excretion decreased by 7.7% .Experimental results show that long light, especially continuous light Can increase the growth rate and energy efficiency of larvae, and can be an effective measure to increase production efficiency when larvae are cultured in large quantities.
