项目摘要
1. We tried to establish the method to rear juvenile sea urchins from fertilized eggs in the marine laboratories where the equipment for aquaculture is not fully available.2. We could obtain several thousands of juvenile sea urchins in 7 species, Pseudocentrotus depressus, Anthocidaris crassispina, Hemicentrotus pulcherrimus, Temnopleurus toreumaticus, Echinostrephus aciculatus, Strongylocentrotus nudus and Mespilia globulus.3. Pluteus lavae were kept in 25 litter paper-filtered sea water in 30 litter plastic vessels (6 plutei/ml). A diatom, Chaetoceros gracilis, was found to be the most suitable food of the larvae.4. When the larvae reached 8-arm stage and the sea urchin primordium grew large enough within them, they were transferred into a 500 litter plastic vessel and given plastic plates which were covered by diatoms. The larvae immediately began metamorphosis on the plates.5. The juveniles were fed by sea weeds such as Ulva and Sargassum. When they became 5-10 mm, they were released into the sea.6. The maximum number of juveniles obtainable from a 500 litter vessel will be 10,000.
1.在水产养殖设备不齐全的海洋实验室中,尝试建立用受精卵培育海胆幼鱼的方法。我们可以获得7种数千只幼海胆,分别是:低位伪球藻、粗刺花球藻、粉刺半球藻、金龟子、尖刺棘球藻、裸圆球藻和球囊海胆。在30个塑料容器(6个/ml)中,用25个滤纸过滤的海水保存大口海藻。一种硅藻--纤细角毛藻--被发现是该幼虫最适宜的食物。当幼虫发育到8臂阶段,体内的海胆原基足够大时,将它们转移到500升的塑料容器中,并给出覆盖有硅藻的塑料盘。幼虫立即开始在平板上变态。幼虫以石杉和马尾藻等海草为食。当它们长到5-10毫米时,它们被释放到海里。从500只小船上最多可以获得10,000只幼鱼。
