摘要研究了光照强度、光质和光周期对马来沙水母Sanderia malayensis幼体(伞径为2.3～2.8 cm)生长的影响。结果表明:光照强度、光质和光周期对马来沙水母幼体生长均有显著影响。自然光组(1 500 lx)和弱光组(750 lx)马来沙水母幼体的伞径显著高于黑暗组(P＜0.05);红光组水母幼体的伞径一直表现出明显的优势,试验第11天后白光组水母幼体的伞径也开始显现优势,白光组与红光组水母幼体的伞径均显著高于蓝光组(P＜0.05),说明水母幼体对蓝光很不适应;光周期(L∶D)为16 h∶8 h组水母幼体的伞径显著高于其它试验组(P＜0.05),说明马来沙水母幼体喜光照,适当延长光照时间有利于其幼体生长。

Abstract: The effects of light(light intensity,light spectrum and photoperiod)on the growth of jellyfish Sanderia malayensis larvae were studied.The results showed that there were better grown under natural light and lower light than those in darkness(P＜0.05).The larvae in red light group showed the best growth performance all the time, and the larvae in white light group had a better growth performance at the last two parts of the experiment,their umbrella diameters being all significant higher than those in the blue light group(P＜0.05),indicating that the larvae were not sensitive to blue light.There was significantly larger umbrella diameter in the larvae in the photoperiod of 16 h L∶8 h dark than that in the other groups(P＜0.05).It is suggested that suitable length of light period facility the growth of the jellyfish larvae.

Key words: Sanderia malayensis growth of larva light intensity light spectrum photoperiod
