确定了四种食物（卤虫无节幼体、轮虫、微藻小角毛藻和等鞭金藻）和四种温度条件对海洋观赏虾幼体 Lysmata wurdemanni 生存和发育的影响。用角毛藻或等鞭金藻喂养的幼虫最多只能存活 17 天，然后发育成幼虫 IV。饲喂卤虫无节幼体或轮虫的幼虫从幼体II期到后期幼体的存活率分别为66.7%和68.9%，差异不显着（P>0.05）。但用卤虫无节幼体喂养的幼虫生长速度明显快于用轮虫喂养的幼虫（P < 0.05）。用卤虫无节幼体喂养的幼虫在 29-32 天达到幼体后期，而轮虫处理的幼虫则需要 32-36 天。卤虫无节幼体也是卤虫后期幼体和幼体的合适食物。取食卤虫无节幼体的30只虾苗均在50～70 d内存活达到性成熟，全长约7～28 mm。还研究了四种温度条件对 L. wurdemanni 幼虫发育的影响。在26℃（37.4+/-5.4）和每天26-30℃（40.2+/-5.8）温度下到幼虫的持续时间（平均值+/-SDd）显着（P<0.05）长于每天28.5℃（29.3+/-4.8）和27-29℃（28.7+/-3.5）。
The effects of four kinds of foods (Artemia nauplii. rotifer, and microalgae Chaetoceros gracilis and Isochrysis galbana) and four temperature regimes on survival and development of larval Lysmata wurdemanni, a marine ornamental shrimp, were determined. The larvae fed with Chaetoceros or Isochrysis only survived for a maximum of 17 d, before developing to zoea IV. The survivorship of the larvae fed with Artemia nauplii or rotifer from zoea II to post-larvae was 66.7% and 68.9%, respectively, without significant difference (P > 0.05). But larvae fed with Artemia nauplii grew significantly (P < 0.05) faster than those fed with rotifer. Larvae fed with Artemia nauplii reached postlarvae in 29-32 d, compared with 32-36 d in the rotifer treatment. Artemia nauplii are also suitable food for the postlarvae and juveniles of L. wurdemanni. The 30 postlarvae fed on Artemia nauplii all survived to reach sexual maturity in 50 to 70 d, growing from about 7 to 28 mm in total length. The effects of four temperature regimes on larval development of L. wurdemanni was also investigated. The duration (mean +/- SD d) to the postlarvae at temperatures of 26 C (37.4 +/- 5.4) and of 26-30 C daily (40.2 +/- 5.8) was significantly (P < 0.05) longer than that at 28.5 C (29.3 +/- 4.8) and at 27-29 C daily (28.7 +/- 3.5).
