摘要
通过对方格星虫（Sipunculus nudus）亲体进行50 d水泥池培育至成熟试验,试验水温18-24℃、盐度27.5-30.8,研究方格星虫人工培育条件下的生活习性与生殖细胞发育,成功实现亲体产卵受精。结果显示：雌星虫成熟率为93.3%,雄星虫成熟率为40.0%,培育平均死亡率为18.7%,试验方格星虫亲体生殖细胞成熟率与自然海区成熟个体无显著差异。
A50-day experiment on pro-body cultivation of Sipunculus nudusbroodstockwas conducted in cement tank at water temperature of 18-24℃ and salinity27.5-30.8.Living habitsand germ cell development were studied under artificial cultivation condition.Spawning and fertilization took place during the period of this experiment.The result showed that female and male S.nudusmaturation ratewere 93.3%and 40.0%,respectively.Average death rateof parent worms was 18.7%.There was no significant difference between the tested S.nudusbroodstockand the mature ones from the sea in terms of germ cellmaturation rates
