| 为了探索龙虾叶状幼体培育的新路子,采用经沙-活性炭过滤海水与投扁藻(Platymonas subcordiformis)和金藻(Dicrateria sp.),漂白粉和孔雀石绿消毒海水与投扁藻和金藻,对虾全封闭养殖池水和底泥等多种培育水质,分别于水缸和玻璃缸进行中国龙虾(Panulirus stimpsoni)叶状幼体培育对比试验。投喂卤虫(Artemia salina)和文蛤(Meretrix meretrix)卵巢。5d投1次25×108 cfu/m光合细菌。用窗帘控制光照度为1000 lx~1500 lx。发现采用对虾养殖池水与加铺1cm厚对虾池底泥的培育水中有种类繁多,生物量丰富的浮游植物、浮游动物、底栖生物。利用光合细菌和调节光照保持浮游植物处于正常生长相,使水中微生物、浮游植物、浮游动物、底栖生物、叶状幼体处于生态平衡并相对稳定状态,取得较好的培育效果。 |

| Abstract: |
| To seek the new method for the phyllosoma culture of spiny lobster,the comparative experiment on the culture-water quality of Panulirus stimpsoni phyllosoma was carried with the seawater filtered through sand-activated and added algae Platymonas subcordiformis and Dicrateria sp,the seawater disinfected with bleaching powder and malachite green and added algae,the seawater and bottom soil from the shrimp-pond for the closed culture.The phyllosoma were fed with Artemia salina nauplii and Meretrix meretrix ovary.The photosynthetic bacteria at 25×108 cfu/m were added to the culture-cisterns per 5 d.The illumination at 1000 lx~1500 lx was controlled with curtain.It is indicated that there are many and complex species of phytoplankton, zooplankton and benthon in the culture water with 1 cm bottom soil from shrimp-pond. The phytoplankton growth phase is properly regulated with photosynthetic bacteria and illumination. The eccological equilibrium and the ecological homeostasis between microorganism, phytoplanton, zooplankton, benthon and phyllosoma are preserved in the culture-water. the culture of phyllosoma is smoothly progressed. |
