Embryonic and larval development and artificial breeding of sea urchin (Temnopleurus hardwickii)

  • Fund Project: 国家重点研发计划"蓝色粮仓科技创新"项目(2018YFD0901603)
  • 为实现哈氏刻肋海胆(Temnopleurus hardwickii)的人工繁育,对其进行人工催产、授精、孵化、幼体培育及人工养成,并在显微镜下观察了哈氏刻肋海胆从受精卵到稚胆的发育过程。结果表明:通过注射KCl溶液的方法催产,可以顺利促进哈氏刻肋海胆排放精卵,排出的卵受精率为93.6%±2.1%;哈氏刻肋海胆胚胎和幼体发育过程可分为受精卵、卵裂期、囊胚期、原肠期、棱柱幼体、二腕幼体、四腕幼体、六腕幼体、八腕幼体和稚胆等10个时期;在水温23~24 ℃条件下,受精卵在50 min时开始卵裂,5 h时进入囊胚期,10 h时进入原肠期,18 h时进入棱柱幼体阶段,23 h时进入二腕幼体阶段,1 d 16 h时进入四腕幼体阶段,7 d 2 h时进入六腕幼体阶段,10 d 16 h时进入八腕幼体阶段,35 d时变态为稚胆;与其他种类海胆相比,哈氏刻肋海胆在四腕幼体之前发育较快,在四腕幼体之后发育较慢。研究表明,在水温23~24 ℃、盐度29~32条件下,哈氏刻肋海胆可以在室内实现人工育苗并进行人工繁殖。
