摘　　要：油彩蜡膜虾(Hymenocera picta)是一种常见的海水观赏虾,色彩鲜艳专食海星,深受水族爱好者欢迎。为此对油彩蜡膜虾繁殖习性、繁殖周期和胚胎发育过程进行了观察。油彩蜡膜虾亲虾交配行为由雄性主导,主要有接触、攀爬跨坐、转移精荚和分开4个阶段。雌性在交配2h后产卵,在水温(27±0.5)℃条件下,胚胎经14~15d发育,经过受精卵期、卵裂期、囊胚期、原肠胚期、前无节幼体期、后无节幼体期、膜内溞状幼体期和孵化前期8个阶段直至幼体孵化,幼体孵化后12~48h内雌性亲虾蜕壳,蜕壳2h内再次开始交配,进入到下一个繁殖周期。Hymenocera picta is popular in the aquarium market due to its attractive coloured pattern of the body and special feeding behavior on starfish.For this reason,observations and records have been made on the reproductive habits,reproductive cycle and embryonic development of harlequin shrimp.The results showed that the mating behavior of the broodstock was dominated by males in four main stages of contact,climb and straddle,spermatophore transfer and separation.Egg spawning occurred 2 hours after mating.Under the temperature of(27 ± 0.5) ℃,embryos developed in 14 to 15 days,going through 8 stages of fertilized egg,cleavage,blastula,gastrula,pre-nauplius,post-nauplius,membrane-zoea and pre-hatching until larvae hatched.Females molted within 12 to 24 hours after larvae hatching and began mating again within 2 hours,and then entered the next breeding cycle.Our results provide not only a better understanding of the reproductive biology in Hymenocera picta,but also a useful reference for its artificial breeding practices.
