中文摘要:
      本文报道了有关海胆人工育苗的方法并对大连紫海胆幼虫的生长发育和变态作了详细描述。大连紫海胆的幼虫可分为棱柱幼虫、二腕长腕幼虫、四腕长腕幼虫、六腕长腕幼虫和八腕长腕幼虫五个时期。在山东省荣城浬岛海区大连紫海胆的育苗时间为7—8月。在水温为23—24℃时自受精卵发育至变态成幼海胆的时间大约需要19—20天。幼虫的饵料以角毛藻为最佳而幼海胆的饵料早期为底栖硅藻后期以石药较为合适。
英文摘要:
      In Rongcheng county, Shandong province, the best time for artifi-cial rearing of larvae and juveniles of the purple sea urchin Strongylocentrotus nudushas been found to be from July to August. The fertilized eggs develop into young urchins for 19--20 days at 23--24℃. Thelarvae show preference to certain algae for food, among which Chactoceros mulleriis found to be the best in use. And ulva is found to be the best food for youngurchins. The duration of early embryonic development stages is summarized as follows.
