摘要/Abstract

摘要： 摘要：本文报道了2010年至2011年在两种不同粒径范围的海沙中培育裸体方格星虫中苗效果比较。结果表明，幼苗在粒径250um～500um的海沙中养殖较在粒径63um～250um的海沙中具有明显的生长优势和存活率。铺设适宜粒径的海沙是提高裸体方格星虫苗种中间培育生长率和存活率的重要因素。

Abstract: Abstract: A growth experiment was conducted to evaluate the effects of various size range of marine sand on the growth and surviva1 rate of Sipunculus nudus L. in intermediate culture stage in 2010 and 2011.The results showed that the larva of Sipunculus nudus L. have a growth advantage and a higher surviva1 rate cultured in marine sand of 250um～500um than those which cultured in marine sand of 63um～250um.The results indicated that the size of marine sand wase important to improve Sipunculus nudus L’S intermediate culture.
