中文摘要:
      中国龙虾叶状幼体孵出后1~2h就开始摄食,其适宜的开口饵料为卤虫无节幼体.叶状幼体Ⅱ、Ⅲ、Ⅳ期摄食卤虫无节幼体后的变态率分别为80%、40%和32.5%.卤虫幼体和贻贝卵巢混合投喂.可提高叶状幼体的存活率.叶状幼体对不同饵料具有选择性,昼夜均可摄食,没有明显的摄食节律性;光照和黑暗对叶状幼体的摄食和存活没有影响.在适宜的卤虫无节幼体密度下,叶状幼体5~9min就可饱食,然后经过45~90min消化完毕;初孵叶状幼体对不同大小的卤虫无节幼体(349.5~604.9μm)的摄食没有明显差异.本试验可为开展中国龙虾的人工育苗积累资料.
英文摘要:
      The phyllosoma of Panulirus stimpsoni begin to feed about 1 -2 hours after hatching , and suitable diet of phyllosoma is Artimia salina nauplii. During phyllosoma stage Ⅱ、Ⅲand Ⅳ they eat A . salina nauplii. Its metamorphosis rate could reach 80 % ,40 % and 32. 5 % respectively. Phyllosoma have choice on different diets , and they can feed all day , and they have no rhythm of feeding. Light and darkness have no effect on their feeding and survival. In suitable density of A . salina nauplii , phyllosoma ( Ⅰ) can be full in 5 -9minutes and digest in 45 -90 minutes. The feeding of phyllosoma on different sizes of A . salina nauplii (349. 5 -604. 9μm) makes no obvious difference. This study can accumulate materials for the artificial culture of Panulirus stimpsoni phyllosoma.
